We were intrigued and excited by a recent press release from Land O’ Lakes announcing that their retail operations would be installing WiFi for the use of their customers. In the best of times the rural ag retailer can be a lifeline for local farmers; in these difficult times, offering services to help local farmers and their families keep connected and work effectively, even if remotely is absolutely commendable.
We salute the Land O’ Lakes leadership and stand ready to assist any of their affiliated retailers in deploying WiFi on their rural locations.
Whether you’re a farmer needing to have connectivity in the farm office (and perhaps share your connection with a neighbor in need) or a rural business wanting to help your employees and rural communities stay online, Ayrstone can help. Just drop us an email at firstname.lastname@example.org and we’ll work with you.
We are pleased to announce the availability of the new AyrMesh Cab Hub2, designed for use with a wide variety of farm equipment: tractors, sprayers, spreaders, harvesters, trucks, utility vehicles – just about anything that rolls and has a 12 volt utility plug.
The AyrMesh Cab Hub2 is a variation of our AyrMesh Hub2x2 design, with two high-gain magnetic mount antennas to provide MIMO (Multiple Input, Multiple Output) for high bandwidth and better signal integrity.
This new model of the AyrMesh Cab Hub combines the best qualities of our previous model of the Cab Hub – ease of setup and use – with improvements to make it even easier to set up, as well as significantly better overall performance.
We have been trying to bring out a MIMO version of the Cab Hub for quite a while, but we kept running into problems with the radios we were trying to use. This radio, however, passed all our tests with flying colors and has been rock-solid.
Because it is based on the same weather-resistant design as the Hub2x2, the Cab Hub2 can be used on enclosed cab machines or machines without a cab – open-cab tractors and even utility vehicles and ATVs.
The Cab Hub connects with the stationary Hubs in your AyrMesh network and provides both WiFi and Ethernet connectivity to your vehicle and the area around it. It even connects with other Cab Hubs to extend your WiFi network where you may not have stationary Hubs.
As Machine-to-Machine or M2M communications becomes increasingly important, the Cab Hub2 provides a simple, high-bandwidth, reliable way to connect vehicles to each other and to external servers, on the farm or in the cloud. Meshing WiFi is faster and more reliable than cellular, and available anywhere it’s needed without carriers or subscription fees.
As autonomous farm vehicles become available, M2M communications will become even more vital to farm operations. For that reason, we are also offering the Cab Hub2 in OEM packaging for integration into new autonomous platforms and products. The product is available at a board level up to the complete product, according to the integrator’s needs.
We firmly believe that meshing WiFi is the only communications solution that enables autonomy on the farm – please contact us today to talk more about your autonomous solutions and needs. At the beginning of this article I said the Cab Hub is good for anything that rolls – but we’re talking to folks who make things that fly, too!
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!
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!
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
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
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.
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:
“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
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.
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.
As you know, I think that the “Internet of Things” (IoT) has enormous potential for the farm. But we have all been recently reminded of the problems we are facing as BILLIONS of new devices come on to the Internet – Friday October 21, the IoT literally broke the Internet.
This event has been called the “Mirai botnet attack.” This is an extremely important event, because it used IoT devices to effectively bring the Internet to a stop for several hours on Friday, October 21. Even Ayrstone was affected: we use Zendesk for our customer support portal, and it was unavailable off and on on Friday.
This attack was innovative in two ways: first, it did not attack the affected sites directly, but rather attacked the Domain Name Servers (DNS, the servers that turn domain names like ayrstone.com into IP addresses like 220.127.116.11) of Dyn.com, making a huge number of websites, including Zendesk, Twitter, and others unreachable, even though they were working just fine.
But the most important innovation was the way the attack was done – using a Distributed Denial of Service (DDoS) attack from IoT devices. DDoS attacks work by sending a huge amount of data to a server from a large number of devices on the Internet, overwhelming the server and causing it to fail. Up until now, the “botnets,” as the devices sending the data are known, have mostly been personal computers infected with viruses that allow a remote user to control them and cause them to send out streams of data to the target server.
As I mentioned, however, this attack was different, because it used IoT devices – IP cameras, routers, wireless networking devices, and other little devices that people don’t see as being “computers.” But your router or IP camera has a lot more computing power than the powerful desktop computer you had just a few years ago.
Hackers were able to access these devices and install “botnet” software on them because – and this is THE IMPORTANT THING – the passwords were NEVER CHANGED from the defaults. For instance, many devices come with a default username of “admin” and a default password of “admin” or “password.” If those are not changed and they are exposed to the Internet, they are an open invitation to hackers.
Now, most of the devices on your network are NOT currently exposed to the Internet – they are safely hidden from the Internet by your router’s NAT firewall. But it is still important to change the default password on devices, and, if you have “port-forwarded” to any devices to make it accessible via the Internet, it is DOUBLY important to make sure it has a STRONG password to protect it.
Ayrstone products, of course, are protected because the username and password for each device is set from AyrMesh.com. The only way an AyrMesh device can have the default username and password is if you don’t have an AyrMesh.com account, and we regularly disable devices that are not checking into an active account. However, even at that, AyrMesh devices should always be used behind a router’s firewall and not exposed to the Internet.
These devices are incredibly useful when used properly, but you have to take some minimal precautions to keep them safe. More information about the Mirai botnet attack and security of IoT devices can be found in this article and elsewhere.
This attack is a good reminder of three things:
Make sure you always use good passwords (long, not a quotation or word) on ALL devices and keep those passwords secret,
Don’t expose devices to the Internet unless you have to, and
Purchase networking/IoT products from reliable vendors who can update the firmware to close vulnerabilities, preferably automatically and over the network. If not, make they make new firmware available to close holes as they are discovered, and install it regularly.
AyrMesh devices have firmware that is updated over the network. We issue several updates per year, and you needn’t do a thing – they happen automatically.
