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?

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.

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.

 

 

Getting the most out of your router, part 3

File not foundOnce you have your router set up properly, your devices on-line, and ports forwarded to those devices, there’s one more small problem: being able to reach your devices over the Internet. There are two problems: first, Internet Service Providers (ISPs) usually provide dynamic IP addresses, so your “home address” may change from time to time; second, IP addresses are hard to remember.

The solution is what is called “DDNS” – Dynamic Domain Name Service. Domain Name Service (DNS) is simply the service that translates a domain name (ayrstone.com) into an IP address (162.159.242.105) so you can access it. DDNS is a service that continually and automatically updates the IP address so that you can always reach your home network using a simple, easy-to-remember domain name.

There are two parts to DDNS: first, it involves a service, for which there is usually (but not always) an annual fee, and an “updater” that notifies the service when your IP address changes. Dyndns.com is the leader in this area; they used to offer a single DDNS account for free, but they have since gone to charging $25 a year. For this they offer a very good service with email support if you need it.

Using Dyndns.com is very easy: you typically sign up with a username (e.g. “ayrstone”) and you can select an extension on one of their “house” domains (e.g. ayrstone.dyndns.org – you can actually select up to 30 – or you can use a domain name you actually own). You then need to set up an “updater:”

  1. Many brands of routers have an updater “built in” for dyndns.com, or
  2. You can download a small program from http://dyn.com/support/clients/ that you run on a computer that is ONLY in use on your home network (it won’t help if it updates your domain name to point to Starbucks…) so it can automatically tell when your IP address changes and “tell” dyndns.com.

One of the advantages of using Dyndns.com is that many brands of router are pre-configured for them; all you have to do is fill in your credentials and go. Dyndns.com also has good, downloadable background programs to run on your home or office computer to update the IP address – this is actually how I use the service. My router doesn’t have a built-in Dyndns.com updater, but my office computer is always on here in the lab, so that’s the easiest way to keep Dyndns.com up-to-date on the lab’s IP address..

There are still a number of organizations that offer free DDNS, and here’s a nice article on Lifehacker that talks about them. The free DDNS services are generally not as convenient: many routers don’t even have a “generic” DDNS setup, but, if yours does, that’s what you’ll use if you want the router to update your IP address. If not, most of them have instructions how to set up a script on your home PC to update the address – entirely doable, but not as easy as just downloading an application. Also, most of the free services don’t have any technical support – they’ll typically have “FAQs” on their site, but you’re on your own. I use one of the free services at home, and it works just as well as Dyndns.com, but it was a bit tricky to set up.

Once you get it set up, accessing your home or office network is simple: just use the domain name you selected. For instance, here in the lab I have my desktop computer accessible via VNC accessible on port 7999, two IP cameras (ports 9005 and 9006), and a weather station on port 8000 (as well as my router on port 80). If the lab’s DDNS domain is ayrstone.dyndns.org (it’s not really, of course… even though everything here has a good password, I’m not inviting people to try to hack them), then I can VNC into my computer at ayrstone.dyndns.org:7999, view my IP cameras at http://ayrstone.dyndns.org:9005 and 9006 (I actually have IP Cam Viewer on my phone set up for those ports already), view my weather station at http://ayrstone.dyndns.org:8000, and re-configure my router at http://ayrstone.dyndns.org (port 80 is the default for http connections).

If your goal is to automate information-gathering and enable remote control for machinery on your farm, you need to have access to your farm’s network from wherever you are. DDNS is a way to make that much easier.

Bringing WiFi into your Cab – the new AyrMesh Cab Hub

crowded_cabThere’s a lot of data being collected by monitors in the cabs of tractors, sprayers, and combines, and getting that data someplace it can be used can be critical to your operation. Today we are introducing a way to connect your tractors, sprayers, combines, and trucks to your AyrMesh Network: the AyrMesh Cab Hub.

The AyrMesh Cab Hub is a combination of three things: our trusty, patent-pending AyrMesh Hub2n, a cable that allows the Hub to be powered from a normal 12 volt utility “cigarette lighter” plug, and an external magnetic-mount antenna to get the Hub’s antenna outside and up in the clear.assembled-2_small

When it is all set up, the AyrMesh Hub2n rides inside the cab of your vehicle, protected from shock and vibration, but mounted where you can see the “signal lights” if you need to. The cable is plugged into one of the 12v utility outlets, and the antenna is put on a ferrous surface on top of the cab. The Hub connects to the other Hubs in your AyrMesh network, giving you WiFi connectivity in your cab.cig_lighter_sm

Antenna on roofHub_mounted_smThe most valuable data on the farm, and some of the hardest data to move to where it can be effectively used, are the data trapped in the monitors on your machines: as-seeded, as-applied, and harvest data. Getting that data out has been laborious (moving Compact Flash cards) or expensive and uncertain (using cellular links), so we’re trying to make it easier with the AyrMesh Cab Hub.

By using the AyrMesh Cab Hub, you’ll have a strong WiFi signal in your Cab whenever you’re in range of one of your other AyrMesh Hubs – up to 2.5 miles away. This means you can use your smartphone, tablet, or laptop from the cab of your tractor, sprayer, combine, or truck. It also makes it easy to transfer data from your WiFi-equipped in-cab monitors, like an AgLeader monitor with their AgFinity adapter, using your AyrMesh network. If your equipment doesn’t currently have WiFi, talk to your dealer about it – vendors are rolling out new products all the time.

If your monitor supports WiFi data transfer, you can use your AyrMesh network to transfer data from your monitor without having to rely on expensive and unreliable cellular links.

Why AyrMesh.com?

ayrmeshThis is one of the questions we get in Ayrstone support from time to time: why do I HAVE to use AyrMesh.com? Why isn’t there just a setup menu on the device?

My answer is simple: if you’re using a single Hub, then it doesn’t much matter:  you have to set the configuration on the device or you have to set the configuration on AyrMesh.com. About the same amount of effort.

But, if you’re using more than one AyrMesh device – Hubs or Receivers – on your network, using AyrMesh.com saves you time, because all your devices automatically configure themselves from AyrMesh.com. Furthermore, because they check into AyrMesh.com every few minutes, you can always check there to make sure your AyrMesh devices are working properly.

Our entire goal in creating the AyrMesh System was to make it so easy that anyone could set it up and use it, and you’d spend as little time as possible fiddling with your network and as much time as possible enjoying its benefits. AyrMesh.com is an important part of that value

Great post on “Precision Ag Explained”

Adam Gittins of HTS Ag got an AyrMesh Hub2n a few weeks back, and he has published a great post about it on the outstanding blog “Precision Ag Explained.” The post helps explain how Wireless Farm Networking is going to drive better and more efficient farm operations in his view.

Here’s hoping we can see a lot more from him in the future – we really appreciate having someone of his experience and expertise writing about Ayrstone.

New Ayrstone Product: the AyrMesh Receiver

Receiver July 2013 Front_400hiToday we’re announcing a new product in the Ayrstone AyrMesh line: the AyrMesh Receiver.

The AyrMesh Receiver is actually, of course, more than a receiver – it transmits and receives data – but it is designed as a simple, low-cost way to put one or more “wired” (Ethernet) devices onto an AyrMesh network. It is very similar to our AyrMesh Hub, but with a couple of important differences:

  1. The AyrMesh Receiver connects to the Hub’s WiFi signal, not the wireless mesh signal.
  2. The AyrMesh Receiver does not create its own WiFi access point – it is a client device only
  3. The AyrMesh Receiver uses a directional antenna for maximum range – it can be positioned up to 2 miles away from an AyrMesh Hub (optimal conditions).

Typical uses for the AyrMesh Receiver include:

  1. Using high-end IP cameras or other network devices that do not have WiFi
  2. Bringing the AyrMesh network inside of metal buildings – an AyrMesh Receiver can be placed on the outside of the building and devices inside can be connected to the LAN port of the receiver. You can even put a WiFi access point inside the building so you have WiFi indoors as well as outdoors.
  3. Connecting devices like network-enabled weather stations in more distant fields – since the AyrMesh Receiver can be up to 2 miles from your furthest Hub, you can now include areas in your network that were previously unreachable.

The AyrMesh Receiver is available now from Ayrstone – please see our website for details.

This is what it’s about: Ayrstone on the farm. This is Matt Hughes’s farm in IL

This is a blog about Ayrstone, our products, networking, particularly wireless networking, the internet, farm/ranch management, and whatever else we find interesting. The primary author is Bill Moffitt, President and Chief technical guy for Ayrstone Productivity.

As Ayrstone customers who have spoken to me can attest, my interests are many and varied, but they always circle back to ways to get things done better, cheaper, safer, and more effectively. I am a strong proponent of technology, but I’m not really what you might call an “enthusiast.” I think of myself more as a crash-test dummy: I want to try new things, see what the potential is, and then talk about what I find (good or bad). The nice thing about this is, I hope, I can find things that are genuinely helpful. The bad part, of course, is that you may not always agree with my assessment. But, of course, that’s what makes this interesting: I expect some lively comments and discussions about the relative merits of different approaches here.

Just so you know what to expect, I’m a “machine gun” writer: I’ll go a long time without writing anything, and then I’ll put up several posts in rapid succession.

I welcome your comments, both positive and negative. This world of networking on the farm has a lot of big, new opportunities, and I hope I can help you make the most of it.

If so, I’ll have done my job.
