Introducing the new AyrMesh HubDuo!

We are very pleased to introduce a new generation of AyrMesh Hub – the new AyrMesh HubDuo! If you order between now and October 31, you can get $30 off our special intro price of $349.95, bringing the price to only $319.95 – please use coupon code “hubduointro” for the extra discount.

The HubDuo is the first AyrMesh Hub to feature dual-band WiFi – using both the traditional 2.4 GHz. band and the 5.8 GHz. band for higher bandwidth combined with the same long range as the rest of the AyrMesh Hubs.

The HubDuo uses a single SSID (network name) for both the two WiFi radios. The result is that you can connect to the 5.8 GHz. WiFi when you’re close to the Hub and get up to 100 Mbps bandwidth (speed). Then, when you move away from the Hub, your device will automatically move to the 2.4 GHz. WiFi, where you can get up to 65 Mbps, with bandwidth reducing as you move further away.

The ultimate range of the Hub is similar to the rest of the AyrMesh Hubs, because it still has high-gain antennas to “hear” very faint signals from a long distance away. So there’s really no tradeoff – you get the same long range as the rest of our Hubs with the extra benefit of blazing-fast speed at short range.

The other main benefit of the AyrMesh HubDuo is that the output power can be adjusted so the Hubs can be placed much closer together than our other Hubs. Whereas the Hub2x2 and Hub2T need to be generally be placed at least a mile apart (so they don’t overpower each other), the HubDuo can be places as close together as a few hundred yards with proper adjustment. Just contact Ayrstone support if you need to place the Hubs less than half a mile apart and we’ll adjust the power.

The HubDuos use standard 802.11s meshing, so they will mesh with existing AyrMesh Hub2 devices (Hub2x2. Hub2T, Hub2x2C, and even the Hub2n). The HubDuo makes a great replacement Gateway Hub for your existing AyrMesh network. The HubDuo also makes use of the same external housing we used for the AyrMesh Hub2x2C, making it compact and easy to install and maintain.

We have plans to offer additional features for the AyrMesh HubDuo to give you even greater flexibility in deploying them, including the option for even more “dense” installations. Please watch this space for news – the new generation is going to open new frontiers in wireless farm networking.

The Robots are Coming! The Robots are Coming!

One idea of an autonomous farm…

Every week there seems to be an announcement about autonomous farm equipment – John Deere acquired Blue River in 2017, and then Bear Flag Robotics last year, and now they’re, essentially, announcing Bear Flag’s products as their own. Meanwhile, Case bought Raven Industries last year, after Raven had acquired DOT Technology and SmartAg. Even smaller, specialty-crop companies are getting into this, like GUSS and Fieldin.

The case for autonomous rolling stock is obvious – if you’re not driving the tractor/sprayer/combine/whatever, you can be somewhere else doing something else valuable. And there are times you would really rather have the robot driving…

I have considered tillage to be the activity most ready for automation, so I had applauded Bear Flag’s emphasis on tillage and Deere’s decision to acquire them and offer an autonomous 8R for tillage. I’ll be interested to see how this goes… it’s coming at a time when no-till or strip-till is increasingly popular, but there’s still a lot of the world still digging up fields.

Planting and harvest are difficult, complex, and time-sensitive tasks, so I expect they will be the last to be automated, but that still leaves spraying and cultivating. GUSS out here in California is already out spraying orchards, and, again, I think Deere was smart to acquire Blue River for their vision-based weeding system. It’s not ready to be a blockbuster product this year, but I can certainly see a future where weeding (and possibly other pest control) is done by a self-driving machine. The autonomous farm won’t be a complete “rip-and-replace” operation – I expect we’ll see it come one piece at a time, slowly replacing human labor, just as it has for the last 200 years.

In truth, once you are liberated from having to drive the machine, of course, you can actually employ more machines. You can have multiple large machines, like the Deere 8R tractor or the Raven (now Case) Omnipower platform, working in different fields, or you could conceivably start replacing some of them with swarms of small, nimble machines like the prototype Fendt Xaver seeder or the Australian Swarmfarm sprayer.

However, having multiple machines in the field requires that they be able to communicate with each other and, possibly, with a central server. That communications must be both low-latency (to avoid delays and collisions) and high-bandwidth (to ensure that they can “speak freely” – at times they’ll need to communicate a lot of information). There are a lot of pundits out there telling us that “5G will solve everything” – and the technical specs tell us that could be absolutely true. That leaves only one important question: do you have 5G on your farm today?

If you’re in the 95% or so who answer “no” to that question, you might want to consider another solution – a solution that might even be better. Meshing WiFi was originally designed to enable “Mobile Ad-Hoc Networks” or “MANETs” – exactly what these devices are using in the field. Instead of waiting for a carrier (or several – many farmers I know require two or more phones, because one carrier covers one part of the farm and a different carrier covers another) to come and plant a 5G network on your property, you can start establishing a WiFi network across your property using AyrMesh Hubs and AyrMesh Cab Hubs for your vehicles.

The advantages of using WiFi include:

  • You control the network: what gets covered and who gets to use it
  • It uses your existing Internet connection – no extra charges
  • It connects to your existing LAN – you can put servers on your network so data need not leave your farm
  • It’s standard, so it works with everything, from your laptop to cameras to low-cost soil sensors and controllers… including robots
  • It will get better with time – new versions of WiFi will bring advantages.

This is an exciting time for farming – things are going to change pretty quickly, and there will be real advantages for those who adopt new technologies. The AyrMesh network provides a “backbone” that allows you to adopt those technologies easily, and we’re eager to work with the companies that are producing these new technologies to maximize the value they bring to farmers.

Announcing the New AyrMesh Hub2x2C

AyrMesh Hub2x2C

We are very proud to announce a new product – the AyrMesh Hub2x2C.

The Hub2x2C is something of a departure for us – a more compact, slightly lower-power Hub with lower-gain antennas, built not for absolute maximum range but to provide continuous WiFi for smaller to medium-sized rural operations.

The AyrMesh Hub2x2C is a response to a problem we have been seeing from our customers: the ability to put Hubs 2.5 miles apart is great for covering a lot of acreage, but the “normal” Hubs don’t work well if they are LESS than 1 mile apart – they overpower each other. However, at 1 mile or more apart, the Hubs are really providing “pools” of WiFi around them, because lower-power devices may only have a usable range of a few hundred yards. There are frequently areas between the Hubs that are, effectively, uncovered for a lower-power device.

The new AyrMesh Hub2x2C can be placed half a mile apart, meaning that even a device with a maximum range of 400 yards can have continuous coverage, passing cleanly from one Hub to the next at the extent of its range.

When we first developed the AyrMesh Hubs, the predominant WiFi device was a large, sturdy laptop, with a “normal” strength WiFi radio and fairly large (although hidden) WiFi antennas. We were actually surprised at how far the Hubs allowed a device like this to communicate – typically half a mile, sometimes further.

As WiFi cameras came out, they used similar WiFi adapters as laptops and generally had similar range. Many had (and still have) removable external antennas that can be replaced with higher-gain antennas to even longer range.

However, now the predominant WiFi device is the smartphone, which uses a lower-power WiFi radio to save battery power, and has smaller antennas to minimize their size. And, on top of that, we’re seeing a new generation of “truly wireless” cameras run off batteries – again, using lower-power WiFi radios and frequently without an option for a higher-gain antenna. While a standard laptop might be able to use the Hub from half a mile or more away, these low-power devices will typically only have about half that range – 400 yards or so.

In the fields of a large farm, the problem of limited WiFi range is solved by use of the AyrMesh Cab Hub2 – the Cab Hub2 is easily fitted to tractors, combines, sprayers, pickups – even utility vehicles – to keep the vehicle and occupants in touch with the stationary Hubs.

On smaller farms and rural businesses, however, workers are frequently on foot, so the Cab Hub is not very practical.

The new AyrMesh Hub2x2C Hubs can be placed as close as 800 yards apart (even closer in some instances – we can reduce the transmit power) to completely cover an area in WiFi. Note, however, that they can still be positioned up to 2 miles apart (with reduced bandwidth), and you can still put up to three “circles” of Hubs around the Gateway Hub. So the new Hub2x2C can still be used to “light up” thousands of acres.

One question that has come up is the range from the new Hub to “ordinary” WiFi devices – the answer is that, at least in our testing, it is unchanged relative to the “big” Hubs. The range to phones, tablets, laptops, etc. is primarily determined by the transmit power and antenna quality of the device, not the Hub – we actually found no measurable difference between the performance of the Hub2x2C and the Hub2x2 and Hub2T for WiFi – the only real difference is in meshing with other Hubs.

Please have a look at the new Hub2x2C – it’s a great option for most rural WiFi users!

It’s Back! Part 2 – The AyrMesh Hub2x2

After over a year, we are happy to announce the new version of the AyrMesh Hub2x2! The new Hub2x2, just like the older model, offers twice the bandwidth (speed) of the single-antenna Hub2T and Hub2n. However, this new model offers more transmit power along with high-gain antennas for maximum range – the same as the Hub2T.

This new model of the Hub2x2 has the antenna jacks solidly molded into the case for maximum durability, with durable, high-gain antennae very similar to the antenna on the Hub2T.

We strongly recommend the Hub2x2 as your “Gateway Hub” – the Hub connected to your Router as the origin of your AyrMesh network; for Remote Hubs we now offer either the Hub2x2 or the Hub2T.

In our testing, we have found that the new Hub2x2 delivers up to 65 Mbps to a 2×2 client (as tested with a Samsung Galaxy S10), and over 30 Mbps as a Remote Hub 2 miles from a Hub2x2 Gateway Hub, so it’s much more capable as a Remote Hub than the older Hub2x2 model – faster than the Hub2T.

The one big difference between the Hub2x2 and the Hub2T is in the amount of power needed – the Hub2T requires only about 4.5 Watts, but the Hub2x2 needs about 8 Watts. For this reason, we continue to suggest the use of the Hub2T in cases where power is an issue, like a “field Hub” powered by a solar-panel battery pack.

The new Hub2x2 is available right now in the Ayrstone store – please check it out today and let us know what you think!

P.S. the new AyrMesh Bridge was part 1, this is part 2… stay tuned for part 3!

The Future is Coming – Get Ready for the Robots…

There is an image of farming – bucolic, peaceful, unfettered by the concerns of the technological age. It’s lovely, and many of us indulge it to some degree… but it is patently false. Agriculture is an industry moving quickly on the technology curve as markets demand more, higher-quality, and cheaper food and grains. Specialized implements, higher-horsepower machines, GPS steering, variable rate planting and spraying, and the cellphone have all had an impact on farm productivity. But that’s not all.

The Robots are coming.

Look, anybody who has sat in a tractor or combine moving through the field by itself using AutoSteer has to have thought, “Do I really need to be here?” In various cities around the U.S., we have been witness to Google vehicles (and others) happily (if sometimes slowly) wheeling themselves around town, their human handlers typing away on their laptops. If they can run sedans on public roads, they can run a tractor down a row of corn. There are a lot of questions about what the first (big) bunch of farm robots will be doing, but the Japanese have been using almost completely autonomous mini-tractors for rice transplanting for years. There are a lot of people and companies testing robots around the world for farming – big ones and little ones.

We have been interested in robots on the farm because we had a vague sense they need a lot more data connectivity than is available in most places now. So I read this article with interest; to quote: “Internet access is a problem,” [Scott Shearer, professor and chair of Food, Agricultural and Biological Engineering, Ohio State University] said. “We need 10 megabits per second connection speed.” Data-gathering tools today can capture gigabytes of information that must be able to flow back to the driverless machine quickly and easily; and the machine must be able to communicate to a central location too.

In some places, cellular connectivity may be enough, but, as discussed earlier in this blog, we don’t expect cellular service to improve dramatically in rural America. And it’s going to still be expensive.

Our modest proposal: set up an AyrMesh network on your farm today for long-range WiFi. And be ready for the robots!

A Whole New Kind of AyrMesh Hub – the Hub2x2

The new AyrMesh Hub2x2

After extensive research, testing, and development, we are pleased to announce the all new AyrMesh Hub2x2.

The AyrMesh Hub2x2 is our first Hub to use MIMO to dramatically improve the upload and download speed, both between the Hub and your devices and between the meshed Hubs themselves. The Hub2x2 can deliver up to twice the data speed of the Hub2T, enabling our customers to do things like:

  • Use high-definition security cameras
  • Download manuals, diagrams, videos, etc. up to twice as fast
  • Make and Receive video calls
  • Stream HD movies – even out in the garden

MIMO is a technology that allows a WiFi access point (like the AyrMesh Hubs) to use multiple antennas that receive and transmit multiple “spatial streams” of data simultaneously. Multiple antennas also help make the signal more readily available in difficult places like in trees and around buildings.

The use of MIMO represents a new strategy for AyrMesh Hubs. Previous AyrMesh Hubs traded off bandwidth to achieve maximum range. The Hub2x2 combines outstanding bandwidth and excellent range to normal WIFI-enabled devices, with a small sacrifice in Hub-to-Hub range.

The reason for this tradeoff is that we have found that most of our customers have their Hubs within a mile of each other, and are primarily interested in ensuring good WiFi coverage with excellent speed around their home, pool, gardens, farm office, workshop, barns, chicken coops, and stables. The new Ayrmesh Hub2x2 is designed specifically for those needs while still enabling you to expand your AyrMesh network out into fields and across thousands of acres.

The Hub2x2 vs. the Hub2T

The AyrMesh Hub2x2 is a perfect Gateway Hub for almost any AyrMesh network, because it provides long range and high bandwidth. The Hub2x2 is also a great Remote Hub up to a mile away, making it an excellent product for providing high-bandwidth WiFi around a rural home, farm, or estate. By placing Hubs a mile or less apart, you can ensure a continuous “cloud” of WiFi for your devices.

For Remote Hub installations more than a mile away, we recommend using the Hub2T. Its single antenna “focuses” its signal much more for longer-range applications, which provides better bandwidth at those distances than the Hub2x2.

The only time we will recommend the Hub2T as a Gateway Hub is when a Remote Hub will be positioned over 2 miles away from the Gateway. In this case, the Hub2T will provide better bandwidth to the Remote Hub2T than the Hub2x2 would.

One other point: the Hub2T has MUCH lower power requirements than the Hub2x2, so it is more suitable for solar/wind powered installations.

The new AyrMesh Hub2x2 – a new kind of AyrMesh Hub

As always, please let us know what you think!

 

Introducing the New AyrMesh Receiver

We are pleased to introduce the new model of the AyrMesh Receiver. This new model represents a significant improvement on the older model while maintaining complete compatibility with previous AyrMesh products. This product combines the proven software from our previous model AyrMesh Receiver with new, more capable hardware. The new AyrMesh Receiver is a bit larger than the old model, and offers several new features:

  • Bigger, stronger antenna for more solid links
  • Mounting tabs on the back for mounting to poles or flat surfaces
  • “Extra” external Power-over-Ethernet (PoE) port on the Receiver for connecting external PoE devices like Cameras
  • Standard 48V power injector/power supply so standard 802.3af devices can use the external PoE port

The ability to mount the Receiver on a flat surface (without additional hardware) is a feature that many users requested over the years, and the ability to add an outdoor PoE device will, we think, enable our customers to enhance security and operational awareness.

Overall, the new Receiver represents a significant improvement over the old model. While the old models will continue to work perfectly, you might want to consider replacing an older Receiver with the new Receiver if:

  • It is in a marginal location, where it is just getting enough signal to make the link – the new Receiver’s more powerful antennas can help; or
  • You want to have an external PoE device – like an outdoor PoE IP camera, connected to the Receiver.

As always, we welcome your thoughts, questions, and comments.

Introducing the New AyrMesh Hub2T

We are pleased to announce the new AyrMesh® Hub2T.

The AyrMesh Hub2T is a direct replacement for the Hub2n, but with some important differences. It meshes with the Hub2n and any other AyrMesh “Hub2” products.

First off, the Hub2T is a lot bigger than the Hub2n, with a much bigger antenna and a tougher stainless steel mounting bracket. The bigger antenna improves the performance of the Hub, while the new bracket just makes the entire Hub more stable and reliable, whether it is mounted on a pole or a flat surface.

Paradoxically, the new Hub2T has a little less radio transmitting power (about half a watt vs. almost a watt for the Hub2n), but it performs better than the more powerful Hub2n. Why? That big antenna! Reducing the transmitting power allows us to use twice as powerful an antenna, and (at least to a degree) a higher-gain antenna is better than more transmitting power. Power allows the Hub to “shout” longer distances, but a higher-gain antenna enable the Hub to both “shout louder” and “listen better” – resulting in better overall performance.

The other interesting change is the addition of a “gland” on the bottom of the radio. This gland makes it a bit trickier to install the Hub, but it protects it from water splashing up from below. This addresses concerns we have heard from some livestock operators who want to put Hubs near livestock pens or in milking parlors or farrowing houses, but worry about having to spray water around the Hub. We still don’t recommend spraying water directly up at the Hub, but this Hub will better withstand inadvertent sprays of water from below.

The Hub2T also uses less power than the Hub2n, so it is better for solar-powered field installations – if you have experienced “dropouts” in winter due to low batteries on the solar system, the Hub2T will work better (although that may also be a sign you need to replace those batteries…)

Should you replace your Hub2n with a Hub2T? In most cases, no – you’re not going to see enough of a difference in performance to make it worthwhile. The only exception is where there is a danger of water splashing up from beneath the unit.

But, if you are just starting your AyrMesh network, and as you expand, the AyrMesh Hub2T will be a low-cost, no-hassle workhorse, whether it’s on a building or out in the field.

Quick Note: “5G” technology on the farm

I have a Google Alert for “Wireless Farm” – I get about an article a week (and many of them are about wireless technologies for “server farms” and other odd things). But today I got a link to this article about “How 5G will impact the future of farming.” Intrigued, I clicked it to find a puff-piece about how Deere wants better wireless connectivity so that combines can “talk” to each other via “the cloud,” pointing out that it can take up to a minute with current technology for one combine to upload its data to the cloud, then the other combine to download that data and act on it. A couple of points here:

  1. “5G” mobile technology is based on “millimeter-wave” bands – over 20 GHz. (20,000 MHz.). Current LTE is based on 700 MHz. radios, and previous mobile data technologies (2G/3G) were “piggybacked” on existing 800 MHz. and 1900 MHz. radios. The range and, in particular, the ability of a signal to penetrate solid objects varies inversely with the frequency. So, to have 5G covering the areas cellular covers today requires a MUCH higher density of cellular towers than we have; to have it cover all of the rural U.S. will require thousands and thousands of new towers, a huge infrastructure investment
  2. As I have mentioned previously, the vast majority of cellular infrastructure investment is happening (and will continue to happen) within cities and towns, where the density of opportunities for subscriber revenue makes it profitable.
  3. Within the article, however, is this paragraph:

The term “5G” refers to the fifth-generation wireless broadband technology based on the 802.11ac standard. The packet of technology will bring speed and coverage improvements from 4G, with low-latency wireless up to 1GB/s.

802.11ac is WiFi, not mobile (cellular) technology. Specifically, it is the current generation of WiFI using the 5.8 GHz. (5,800 MHz.) radio band.

And here’s the point: “5G” mobile technology is not going to have an impact on farm operations in the forseeable future. But you can have multi-megabit WiFi technology on your farm TODAY – and you don’t have to wait for your friendly cellular carrier to put up a zillion towers. FURTHERMORE, since your AyrMesh system puts all the devices onto YOUR OWN Local-Area Network (LAN), everything on the system can just talk to each other – they don’t have to upload to the cloud and download from the cloud or anything like that. Your combines can “talk” to each other and your trucks, you can automate processes and enable autonomous vehicles – NOW – with an AyrMesh WiFi network.

 

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.

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).
