The Internet of Things (IoT) on the Farm – Part 3

In Part 1 and Part 2 of this series, as well as the associated posts on the ezeio and sensor networks, I have focused primarily on IoT hardware: the part you can see and touch, and that touches your farm.

Firmware

However, in many ways, software is much more important than the hardware. As I observed in Part 2, modern technology products are remarkably similar: a CPU, some memory, some storage, and some peripherals. If the peripheral is a relay, you have a device that can turn things on and off (like a remote-controlled power plug, or a WebRelay). If the peripheral is an “Analog to Digital Converter” (ADC) then the device can monitor sensors and report the values from those sensors. Some devices like the ezeio have both (and even more).

Of course, nothing happens on these devices without software. And software is involved in at least two important places: the software that is running on the devices themselves, sometimes referred to as “firmware,” and the software running on back-end computers (local or cloud servers, PCs, or even your phone or tablet) that is used to store and interpret the results from the devices.

These two pieces of software have to be able to “talk” with each other, and we’ll assume* they do so over your network, with the device connected to your AyrMesh network and the “back-end” software on some sort of cloud-based server on the Internet. Note that the “back-end” software COULD reside on a server on your property if you are using AyrMesh.

What the devices themselves do depends on both the hardware and the firmware on the device – in most cases, that firmware will collect readings from the sensors, upload that information to the back-end server, and, if appropriate, take commands from that server and take action, from turning on a light to starting a pump or a grain auger.

In most cases, that firmware is a closed system – there is no way for you to collect data off or communicate with the device directly, or to direct it to a location other than the vendor’s cloud server. It doesn’t have to be that way, but (1) it’s simpler, and (2) that gives the vendor much more control over the data.

The back-end server usually stores the data and presents it to you (either through a web page or a mobile app, or both). What data you see, how you see it, and what you can do with it depends on that back-end software. It may just present a time series of observations in the field as a graph, it may let you set up simple or complex rules (if the soil moisture is at this level or below, turn on the irrigation system), and it be able to present data in many useful ways (different graphs, superimposed on maps, etc.) and enable very complex control of your farm machinery.

The back-end server is usually a closed system, as well – most times it can only accept data from the vendor’s own devices. Sometimes it may have an “Application Program Interface” (API) that allows it to exchange data with other programs. It may also have the ability to upload data into it for tracking and presentation, or to download data from it for importation into another program. These APIs and import/export mechanisms may be very good, well-written, and well-documented, making them extremely useful. Or they may not. APIs are generally only useful for programmers – it takes code to make them work – but well-written and well-documented APIs can enable even relatively inexperienced programmers to create custom programs to do exactly what you want, and that can be extremely valuable.

On the other hand, back-end software without good APIs and/or import/export features is a “closed box” – what you get is just what you get, and there’s no way to get more or less. Understand, of course, that a closed system like this may do EXACTLY what you need, but, if your needs change, it may suddenly become useless.

Of course, there is also the issue of your data and what happens to it. The terms and conditions for the service may be very clear about what happens to your data, or they may be quite vague. Many of the data services will anonymize and sell the data that you store on their servers (the most unethical may not even anonymize it – beware!). This may concern you or not, depending on the nature of the data and how closely tied to your operation it is. For instance, it is generally valuable to share weather data – if your neighbors do so as well, you can gain a much better insight into the local weather patterns. On the other hand, you may not want to share geo-referenced harvest data – that tells too many people exactly what your land and your harvest is worth. “Fuzzing up” the geo-reference, however, might make it a lot more shareable.

When you are considering new devices to collect data and/or control machinery on the farm, these distinctions between “open” and “closed” systems, and the availability if good, usable APIs may seem abstract. Salespeople for “closed” systems will do their best to minimize the importance of these issues, but it’s absolutely critical. Openness in the device’s firmware means that the devices can be re-purposed to work with another system if you don’t like the vendor’s services, and openness in the back-end database means you can easily get your data and move it where it can be combined with other data and used (e.g. providing it to your agronomist for analysis, or storing it in a system where it can be combined with other data for decision-making).

Being smart about buying new technology for your farm can save you a lot of money in the long term, and a lot of frustration in the short term. We’ll keep an eye out for and report on interesting products that help you on the farm using open technologies.

*some devices connect directly to the network using WiFi or Ethernet, and some devices will have low-power networking (e.g. Zigbee or Google Threads) that use a “gateway” device to connect them to your network (or directly to a public network via cellular or satellite). There are even some that don’t talk to the network at all, using either Bluetooth or an embedded WiFi server to communicate directly with your phone, tablet, or laptop. And, of course, there are still devices that use some sort of flash memory and “sneakernet” (taking the flash memory off the device and walking it to a computer).

Welcome Eero and Google to the world of Mesh

eerogoogle_wifiSince we started marketing the AyrMesh system five years ago, we have gotten inquiries from folks who have large houses, offices, and small hotels/motels – can AyrMesh work indoors? The answer, of course, is that it can work, but it’s not optimal for a number of reasons, and we do not recommend it. AyrMesh is designed for outdoor use, mainly in rural areas.

We have been able to recommend the fine Open-Mesh products for indoor and urban outdoor use, but some new products have recently entered the market.

Eero was the first in this space, with a very nice-looking product and very good technical specifications. Unlike Open-Mesh, they do not have any way to mount their units outdoors, and they only offer one model (available in a 1-, 2-, or 3-pack).

Then, this week, Google announced the new Google WiFi product, utilizing a very similar approach of very nice-looking indoor meshing access points for larger houses. The Google WiFi products will be available in November, but they can be pre-ordered.

open-meshOpen-Mesh uses their Cloudtrax website and apps to control their access points; we have used Open-Mesh here in the Ayrstone lab for years and found it to be excellent. It’s a fair bit more complicated than AyrMesh, but it has the more “commercial” features you might want for a business or a motel, and the more complex features are easily ignored for a home setup.

It’s worth mentioning that there have long been WiFi Repeaters (also known as “boosters” and “extenders”) that connect to your WiFi router and create a new WiFi signal, and devices like the Apple Airport routers that use “Wireless Distribution System” (WDS). Although a single repeater can work well, and three Apple Airport routers using WDS (one connected to the Internet and two “extenders”) can work, they don’t have the routing “smarts” of a real mesh network, and they can cause more problems than they solve. For a large house, a real WiFi meshing product like these will provide much better results without running Ethernet cables… of course, for the absolute best WiFi, there is no substitute for just running Ethernet and putting separate Access Points in each location you need WiFi. If you were clever enough to run Ethernet to the far reaches of your house before the drywall, all you have to do is plug in some dumb access points in the Ethernet – no need to mess with the indoor mesh.

The new Eero and Google WiFi products use apps to configure and control the network – I don’t know if there is a website option available, but I get the impression that the apps are the only way to control them. I don’t know about you, but my poor phone is “full” of apps, and I really don’t want another one.

So my own view is that these new players are not quite as good as what already exists in Open-Mesh, but, of course, your mileage may vary, Of course, they are being marketed like crazy, so you’re going to see them in the press all over the place.

What I think is important is that meshing WiFi is becoming mainstream, and, if you live in a large house, you don’t necessarily have to run Ethernet to get WiFi throughout the house.

Getting started with the IoT on the farm with ezeio

 

eze System

A few months ago, I was approached by the folks at eze System, who wanted to know if their ezeio product would work with AyrMesh to help farmers measure conditions on farms and control equipment.

ezeio-400px-300x239They were kind enough to send me one of the ezeio products so I could try it out. Insofar as it is a standard Ethernet (802.3) product, I had no doubt it would work perfectly with AyrMesh, and, of course, it did – I just connected it to an AyrMesh Receiver with an Ethernet cable and it appeared on my network.

What is cool about the ezeio is that it is a complete package – hardware, firmware, and back-end software – completely integrated and ready to plug in and go. It includes connection points for up to 4 analog inputs (configurable for 0-10V, 4-20mA current loop, S0-pulse, or simple on/off), Modbus devices, Microlan (1-wire) devices, and up to two relay outputs (up to 2 amps). This makes it a very versatile unit for both detecting and controlling things on the farm.

setup_smallI set mine up on a table to see how it worked. The good folks at eze System included a Microlan temperature probe, so I set up my unit with that connected to the Microlan connector and a couple of LEDs (with a battery) connected to one of the relay outputs.

loginI then went to their web-based dashboard and started setting things up. It’s pretty simple – you get a login on the dashboard, and you add your ezeio controller. You can then set up the inputs (in my case, the temperature probe) and outputs (the relay) and then set up rules to watch the inputs and take appropriate actions. If you want to see the details, I have put together a slide show for the curious so I don’t have to put it all here.

The bottom line is that I was able to quickly and easily set up a system that checked the temperature continuously and, when the temperature dropped below a certain level, lit up an LED. Big deal, I hear you say, BUT – it could easily have been starting a wind machine or an irrigation pump or some other machine, and it could have been triggered by a tank level switch or a soil moisture sensor or some other sensor or set of sensors. It also enables me to control those devices manually over the Internet, using a web browser, without having to “port forward” on my router.

The ezeio is a very powerful yet easy-to-use device which, in conjunction with the web service behind it, enables you to very easily set up monitoring and automation on your farm. For the do-it-yourselfer, it is a great way to get started on employing the Internet of Things (IoT) on your farm. Even if you’re not inclined to take this on yourself, any decent networking technician  can easily set up your AyrMesh network and the ezeio to help around the farm.

Sensor networks

Much has been written about the use of remote sensors in farming, with soil sensors leading the way. I think it’s worthwhile to understand how these sensors work and what options are available

We have highlighted some of these products (gThrive, Farmx, Edyn), and there are others coming up including Cropx and AgSmarts that we have not been able to evaluate in depth yet, although they are very promising and appear to be more focused on “mainstream” agriculture rather than specialty crops.

The soil sensor people understand that, to have soil sensors near the plants, you have to have sensors that are battery-powered (because you don’t get enough sun under the canopy to use solar). Because of that, most soil sensors use a low-power radio system; many use a “Personal-Area Network,” usually based on the 802.15.4 low-power, low-bandwidth meshing standard. These networks allow the sensors to use very little power so the batteries can last for months or even years. Additionally, the bandwidth (the amount of radio spectrum they use) is so low that they can transmit a very long distance with minimal power – frequently hundreds of yards – and the meshing capability means they can cover a very large area in a couple of hops. So these sensor networks actually ARE practical for gathering data from sensors, even in a very large field.

However, these systems, just like your home WiFi network, require a “gateway” device out in the field to connect them to the larger network (your AyrMesh network or the Internet). The Edyn sensor is an exception, because it connects directly to your WiFi network, but it is primarily aimed at gardeners, not commercial agriculture. Davis Instruments uses the weather station as the Gateway device, which makes it simple, but it does not use a meshing system, which limits how many sensors you can deploy. For almost all systems, sensors are not directly on your network or the Internet – the field network is a special network that only “talks” to the gateway device, and the gateway device “talks” to a normal Internet Protocol network – and that is usually a cellular modem connected to the Internet.

I generally discount analyst firms, but I have to reluctantly give kudos to Lux Research for hitting the nail right on the head: sensors are too expensive. With the exception of the Edyn, which you can buy at Home Depot (and connect to your AyrMesh network or other WiFi source), you have to buy:

  1. However many individual sensors you want,
  2. A Gateway device for your sensor network (possibly multiple gateway devices if you want sensors in multiple fields), and
  3. Cellular subscriptions for each gateway device.

This is a lot of “commitment” before you even figure out how to effectively use the sensors and the data that comes from them – thousands of dollars just to get started plus a monthly or annual commitment to get the data. These systems are being marketed primarily to folks growing wine grapes in California or vegetables in Arizona – high-value crops with severe water costs and restrictions.

There are changes coming, of course, but there are also ways to get started now with less commitment.

in_garden_2_smallFirst, if you’re growing a few acres of cut flowers, organic vegetables, or other high-value, high-intensity crops, the Edyn system may be very useful. Put an AyrMesh Hub near your field and deploy the Edyn sensors and valves controllers. You don’t have to save a lot of time and water to justify the expense.

Davis Weather Envoy

Second, Davis Instruments has a nice system that they don’t advertise much. Their Wireless Weather Envoy datalogger can be connected to any Ethernet network (e.g. a Remote AyrMesh Hub, an AyrMesh Receiver, or an AyrMesh Bridge) using their Weatherlink IP module. It can then connect to their Soil Sensor Station, which has up to four soil moisture and soil temperature probes.  It will also connect to a Vantage Vue wireless weather station, which is a very high-quality, low-cost, integrated weather instrument cluster that you can put up in any field in a matter of minutes. There’s a small annual fee for their cloud-based Weatherlink service, but it makes the system VERY easy to use.

If you need more soil sensors, they also build an Envoy 8x, which has the ability to simultaneously “talk” to up to 8 stations – weather stations or soil stations – within about 1000 yards.

batteriesEither the Wireless Weather Envoy or the Envoy 8x can be tucked into the cabinet of the Tycon remote power system we recommend for field Hubs, Receivers, or Bridge radios, and powered from the auxiliary power output on that system.

Third, if you do want to deploy many soil sensors using a system like gThrive or Farmx, you can connect the gateways in each field to an AyrMesh devvice to avoid exorbitant cellular fees for each gateway device. Their gateway devices have Ethernet ports, so they can be connected directly to an AyrMesh Remote Hub, Receiver, or Bridge unit, and you can skip the cellular bills.

We’ll have more on weather and soil sensors – if you have questions or comments, please leave them here (for public response) or contact us.

 

The “Third Wave” of AgTech

paydirtWe wanted to quickly share an article published recently that impressed us quite a bit.

This article in DTN/Progressive Farmer talks about how information technology is making a difference in farming and how that is likely to accelerate in the coming years.

There are a lot of unknowns in the “AgTech” field – most importantly, which vendors and technologies are going to be genuinely important and which will be forgotten. However, one thing is clear: the technology of agriculture, and particularly of agricultural data, is here to stay. And, where you have data, you HAVE to have a way to move it. And, finally, the way to move data is using networks.

So we are encouraged by this article (and others we have seen) that predict increasing importance for data on the farm – it just makes the AyrMesh network that much more valuable for our customers.

The Internet of Things (IoT) on the farm – part 1

tag_cloudI read a LOT about the “Internet of Things” (abbreviated IoT) is in the news lately; you probably have see it too, and there is a lot of excitement around it. And I would argue there’s good reason for that – it is going to change everything, perhaps more fundamentally than cellphones and, later, smartphones. But it is important to understand what the IoT is, what it is not, and how it will affect life on the farm.

The IoT is not a single thing or even a particular class of things; it refers to a new generation of devices that are connected to the Internet and perform some function, with little or no human interaction. There are already a LOT of good examples, from the Nest Thermostat to kid’s Arduino toys, from devices that can be handy almost everywhere like a network-connected lightswitch, to highly specialized devices like grain dryer controllers or irrigation controllers. I would argue that little of this stuff is new; the things we are seeing being touted as “IoT” devices are really the same as things we already have, just made smaller, smarter, and less expensive. Frequently a LOT smarter and a lot less expensive, which is important.arduino

Belkin_wemo_outlet

Belkin WeMo WiFi Outlet

But the profusion of little, inexpensive, smart things all over the place is having effects we can’t fully understand or appreciate yet. The one thing we can predict with some certainty is that the people who understand these devices and put them to use intelligently will see tremendous gains, just as those who started using computers intelligently saw huge benefits. The question, of course, is, “How do I use these devices?”

Technical knowledge is much less important at this phase than imagination – in all honesty, the most technically competent people miss a lot because they are too invested in how things ARE, so they cannot understand how things COULD BE. So I pose this question to you: what on the farm could be made better (faster, cheaper, more profitable, or more enjoyable) by little computers with accurate little sensors (for light, heat, moisture, position, dream_farmmotion, and lots of other things) and robust built-in data communications infrastructure (WiFi)? What could you monitor? What could you control remotely (or even automatically), especially using the data you are getting from monitoring?

We’ll explore this more in future blog posts, but I would like to hear what you have to say, as well.

You can find Part 2 here, as well as a good post about sensor networks.

Saving money with AyrMesh

piggy-bank-1056615_640There are all kinds of new technologies and products available for farming – these new “AgTech” products hold real promise to change the practice and the economics of farming. But you have to evaluate them realistically to understand how they will help you improve your profit: increase revenue or save costs.

AyrMesh was designed specifically to help save costs on the farm, so it provides increased profits no matter what happens to yields and crop prices. There are several ways in which AyrMesh helps you reduce costs, directly or indirectly:

  1. Reduce the cost to simply move data – your cellphone (and maybe your tablet and/or laptop) has a cellular radio for data, and you pay a premium for using more than a minimal amount of data per month. By using the AyrMesh network, however, you can be disconnected from the cellular data network and save money you would have to send to the cellular companies.
  2. Employ new technologies that can save money – because AyrMesh is a standard, Internet-Protocol (IP) network, you can avail yourself of off-the-shelf products that just connect to your network. Examples include things like networked weather stations and soil sensor systems, but also grain dryers and irrigation systems. As security becomes an increasing concern on the farm, having an AyrMesh network allows you to quickly and easily place IP cameras so you can keep an eye on distant parts of the farm
  3. Be prepared for the future – new, time-saving and money-saving products are coming up fast, and you can be ready to put them to work. New autonomous vehicles, remote sensors, and remotely-operated machinery will be able to magnify the effort you put in on the farm, just like tractors and combines did in the late 1800s, increasing the profitability of farms.

But be careful: a lot of products being sold come with a “small monthly fee” to pay for a cellular modem to move data from the device to the company’s cloud servers. It’s a business model that works and it makes it easy to install new products, because the vendor doesn’t have to worry about setting up a network. However, as you adopt more and more of those products, the number of small monthly fees is going to add up fast, and none of them will work in fields without cellular connectivity.

Look, electronics and data aren’t going to grow the crops. But the information they can provide you can help you make better decisions, both season to season and day to day, to save money and increase yields. Smart investment in AgTech begins with thinking about the data – what you can use, how you will use it, and, most importantly, how you will get it from where it is generated to where it is useful. We are here to help with that last bit.

AyrMesh Field Hub – Solar powered to extend the network

frontWe have been asked multiple times how to extend the AyrMesh network beyond the availability of plug-in power. The key, of course, is solar panels and/or wind turbines, along with batteriessemi-front_closed to hold the power when the sun isn’t shining or the wind isn’t blowing.

Tycon Power has solved this problem for us by developing an integrated system just for the AyrMesh products: Hub, Receiver, or Bridge radio. The product to use is their RPPL-1212-36-30 unit. You can buy it directly from Tycon at their store site. This system with the 30 Watt solar panel will work in most of the country that receives an average of 3.5 hours per day or more – the red and dark orange bands on the standard insolation map. For areas in the light orange or yellow areas on that map, you will need to add a second 30W solar panel (with mounting bracket) or a wind turbine to keep the batteries charged.batteries

Tycon also makes larger systems for multiple devices. The RPST-1212-100-70 system will provide power for two or three devices – for instance, a Bridge radio and a Hub or two “back to back” bridge radios.

As with the smaller system, if you get less than an average of 3.5 hours of sunlight per day, you’ll need to augment the power generation of that system with an extra 70W solar panel (and mounting bracket) or the wind turbine.

just_hub

Higher is better

What does it take to set this up? Two things: very rudimentary wiring skills to connect the batteries and the solar panel with the solar controller, and the ability to set up a strong mast or tower. In our tests, we used a 7′ tall free-standing pole, but, for practical use, you’ll want a much taller pole or tower, embedded into the soil with concrete. You need, of course, to get the radios up as high as practical, but at least 25 feet above any obstacles for maximum range. This may require the use of a pole with guy lines or even a tower.

semi-front_openThe system provides Power over Ethernet (PoE) for the radios, just like the power supplies that come with the AyrMesh products. The mechanical considerations (attaching the solar panel and battery pack to the pole or tower) is extremely simple, using either U-bolts or hose clamps.  Using this to extend your network out into your fields will enable you to use the AyrMesh Cab Hub to automatically move data off your in-cab computers and have WiFi coverage in your cab wherever you are on the farm.

If you have any questions about this, of course, please feel free to comment on this post or get in touch with us at [email protected].whole

Long Range WiFi: two approaches

AyrMesh HubWe didn’t invent the idea of putting WiFi on farms and ranches, although I think we’ve done a lot to popularize it. And it’s not really WiFi that’s important, it’s just having a farmwide network that you can connect to and move data with.

When we started, we realized there were two ways we could build out the farm wireless network, and that we’d need to support both ways. However, we had to start somewhere, and we knew that the best short-term “proof of concept” was using the mesh network approach: a bunch of high-power WiFi Access Points that are connected to the Internet and talk to each other using a meshing protocol. That’s what gave rise to the AyrMesh Hub.

Because the Hubs can be up to 2.5 miles apart, it allows you to extend your network out quite a ways from your home place, and that’s useful for a lot of people. It also allows you to “get in the game” for a minimal investment – a few hundred bucks for a Hub and a little time putting it up high and out in the clear gets you WiFi across your farmyard and out into your fields. Then you can extend the network from there with additional Hubs.

However, sometimes you just want to connect someplace into your network, and you don’t need to have WiFi. For those cases, a different approach is optimal: point-to-point microwave links, also known as “bridges.”

AyrMesh BridgeA bridge can use WiFi or a WiFi-like signal to connect two locations and pass data between them. Typically they are “Layer 2” devices, meaning that they work just like a long, wireless Ethernet cable. You plug one radio into your network (typically your router) and then plug the other radio into whatever you want to put on your network (a computer, IP camera, WiFi access point, etc.), and everything works just like it was plugged into your router.

The AyrMesh Bridge uses microwave radios that use the 5.8 GHz. band (used for 802.11 WiFi “a,” “dual-band n,” and “ac”), but they use a special “narrow-band” microwave signal that increases the range, reduces the effects of interference, and makes the signal invisible to WiFi “sniffers.”

Of course, if you are just connecting some distant device or devices into your network, you can also use an AyrMesh Hub and an AyrMesh Receiver. It will actually work the same way; the differences are:

  • The AyrMesh Bridge is just a wireless Ethernet cable that doesn’t provide a wireless signal usable by anything else. The AyrMesh Hub provides WiFi that other devices can use.
  • The AyrMesh Bridge is a “1-to-1” system, but you can have several Receivers talking to one Hub.
  • The Receiver can be up to 2 miles from the Hub, but the Bridge radios can be up to 5 miles apart.

It’s not necessarily an “either/or” thing. Several AyrMesh users are using the AyrMesh Bridge to reposition their Gateway Hub to the top of large structures (e.g. grain legs) to give the Hubs maximum range. A couple of people are using their Hubs for WiFi but providing connectivity to other buildings using Bridges (with the Hub and the Bridge radio mounted next to each other on top of the house or office). And you can use a Bridge connected to a Remote Hub to connect a device several miles away from the Hub.

There are a lot of folks out there selling wireless bridges – we think the AyrMesh Bridge is the best for one important reason: it’s the easiest to set up and use. No configuration is needed: you just connect both radios in the Bridge to your router. They download your configuration from AyrMesh.com and then all you have to do is mount them outside pointing at each other.

Introducing the AyrMesh Bridge

AyrMesh BridgeToday we are pleased to announce the availability of the AyrMesh Bridge.

The AyrMesh Bridge is a simple, wireless, point-to-point bridge. It serves a single purpose – to connect a distant device to your local network – a 5-mile long wireless Ethernet cable.

Wireless bridges have been around for a long time, and we had initially rejected the idea of adding a wireless bridge to the AyrMesh product line. If you have the Hubs and Receivers, why do you need a Bridge?

AyrMesh Bridge mounted

Testing in California

However, several customers have come to us in the last year with the same problem: their Gateway Hubs are on top of their homes or offices, but they would be better placed on top of a grain leg or another building with a better “view” of the surrounding fields.

In these cases, it would be possible to use one Hub near their routers to feed a Hub on the high location, but that would limit the ultimate range of the AyrMesh network (because we recommend only using up to three “hops” across Hubs).

The truth is that there are a lot of places the AyrMesh Bridge can be used:

  • Connecting an isolated outbuilding to your network (if you don’t want or need WiFi – if you want or need outdoor WiFi, of course, the Hub and a Receiver is a better solution)
  • Connecting a non-WiFi device that is more than 2 miles from a Hub or Receiver
  • Any other situation where you think “I wish I had an Ethernet cable that long.”

We are using a special radio signal for the AyrMesh Bridge to maximize the range. It is a narrow-band 5 GHz. signal, which is hidden and fully encrypted. Although it uses the 5 GHz WiFi band, it does not register with any WiFi equipment because it is a narrow-band signal. This minimizes interference with 5 GHz. WiFi  signals, but does not completely eliminate it. If you are using 5 GHz WiFi equipment (802.11a, ac, or dual-band n), you’ll want to use different channels for your AyrMesh Bridge than your WiFi equipment.

Contents_1200wide

Contents of the AyrMesh Bridge package

The AyrMesh Bridge comes complete with two radios (one for each end of the Bridge), power supplies, and 10′ Ethernet cables. Like all Ayrstone AyrMesh products, each radio is initialized by plugging it into your router until it shows up on AyrMesh.com, then it can be installed.

Like all AyrMesh devices, the Bridge radios are controlled by AyrMesh.com, ayrmeshas shown here. There is only one control for the Bridge – the 5 GHz. channel can be set to 149 (the default), 153, 157 (as shown here), 161, or 165. Note that these are distinct channels; unlike the 2.4 GHz. WiFi channels they do not overlap.

The AyrMesh Bridge is the simplest way to connect a device to your network at a considerable distance. Please contact us if you have any questions or comments about it.
