I’d like to see if we can hook up a few MOANs to those Google loons and check distance there
@chamaile0n you could try to replicate Project Loon using a bimp and goTenna mesh.

Nice, where do we follow updates on new algorithm?
I don’t think there is a single perfect place but when they increase the hop limit I’m sure there will be a big buzz in these forums. Here are some snippet from elsewhere on the forum you may find interesting.
Based on current information early 2018 will see improvements but I believe the 2.0 version of the protocol will be the one that may include infinite hops for certain situations. That will probably be late 2018.
EDIT: Something else to look forward to in 2018 is the USB SDK. That will allow us(the general public) to develop software interfaces with pretty much any devices that supports USB host.
USB SDK examples: PC, MAC, Raspberry PI, ect… I personally imagine a USB implementation that connects directly to a WiFi router and may include WiFi mesh protocols.
The problem here is that, by your own admission, it took MANY tries to get a message through at this single hop distance. With FOUR hops, EACH node must be able to successfully send a message in order for the message to go through. So if there is, say, a 10% chance that you will be able to get a message through a given distance on any single attempt (on your part, that is, since the Gotenna actually makes a few attempts on each send), the likelihood of a successful transmission drops to .01 percent for four hops! And this assumes that EACH HOP has the same chance of success. In order for meshing to work with any reasonable chance of success, you clearly cannot be operating at the ragged edge of a Gotenna’s range. You must be close enough that transmissions are decently reliable. Of course, mesh nodes with an external antenna (such as a MOAN or any possible future product developed by Gotenna) could GREATLY increase the reliability of each hop at long distances, making meshing with long hops more feasible.
@StorminMatt one advantage goTenna Mesh has is the ability to re-trying transmissions. If an acknowledgement is not received, the sender can re-try sending the same message and thus increase their probability of success.
If latency is not a major concern, the # of retries can be kept high to ensure reliable comms even when nodes are at the edge of range.
This is true. But when each node is at the very ragged edge of range, the number of tries required can easily skyrocket to the point that it becomes impractical to send a message in this way.
Of course, the ability to send a message through more hops can correct this, as the reliability of each transmission will vastly improve. GliderBen did say that 10 mile transmissions are still quite reliable, even though they are FAR beyond the advertised range of the Gotenna.
GliderBen it seems you are using GoTnna in a glider in a very similar fashion to ADSB TCAST for conventional aircraft?
StorminMatt - agree mesh nodes with any external antenna would GREATLY increase range and reliability. meshing with long hops more feasible with external antenna from an airpane or glider or car.
What is MOAN? Does any Gotenna have a connection a port for connecting an external antenna? Goes the Pro version have a port?
MOAN = Mother of all nodes, which is basically a Gotenna Mesh unit which has been modified to connect to an external antenna. A MOAN also typically includes provisions for remotely powering the unit, such as a solar panel and/or lead acid battery. With this said, the Gotenna Mesh does NOT have a port for an external antenna. The unit must be modified in order to connect it to an external antenna.
The Gotenna Pro actually DOES have a port for an external antenna. Unlike the Mesh (or V1 Gotenna), it can operate on either a UHF or VHF band. But the UHF band it operates on is different (lower frequency) than the ISM band the Mesh operates on. There IS overlap between the VHF band it operates on and the MURS frequencies the V1 operates on. But I’m not sure whether the two are compatible. The Pro operates on licensed frequencies, and therefore requires an FCC license to legally use (not sure what kind of license).
I’ve often thought that a consumer version of the Gotenna Pro would be REALLY, REALLY cool. Like the Pro, it would be dual band - you could operate without a license on either the MURS band at 2W (like the V1) or the ISM band at 1W (like the Mesh). This way, you could take advantage of the strengths of both bands (depending on what is advantageous in a given situation). And you could have compatibility with both V1 and Mesh units. Such a unit would also have an external antenna connection for those situations where extra range is desired (just imagine the point to point range with a Smiley 5/8 Slim Duck or Super Stick while operating in MURS!). I’m not sure how interested Gotenna is in developing such a product, however.
We had our first test away from our home in the trees, & I was somewhat disappointed. On the beach @ Cape Disappointment, WA. (At the mouth of the Columbia River) and only got a couple Km. 46.2967, -124.0753 to 46.2784, -124.0766. And the campsite, 0.4 Km in from the surf and about midway between was mostly occluded. Short trees and a sand dune ridge were the obstacles.
Keep in mind that placement of the units can have a HUGE effect on range. For instance, keeping your Gotenna in your pants pockets virtually guarantees poor range. Even a jacket or hoodie pocket will work LOTS better. Mounting the Gotenna high on a backpack works better yet, but make sure it is not accidentally sandwiched between the backpack and your back (I’ve made this mistake). And if you are more than just a short distance from the other Gotenna, it helps LOTS if you have your Gotenna on the side of your body facing the other Gotenna - you lose LOTS trying to transmit/receive through human flesh. Of course, if all else fails, you can hold your Gotenna in the air.
It should also be noted that these same things need to be considered on the other end. If, for instance, you try to position your Gotenna for optimal reception but the other person DOESN’T, you won’t be able to send or receive well. If you are communicating with a base camp, it is probably best to hang the Gotenna there in a tree for optimal reception.
All good points.
HT best operating procedures continue to apply.
For the most part, yes.
Hmm. Wonder if someone will invent a hiking hat with a GT slot on top!
What I call my “go to [heck] hat” is an Army surplus bush hat that I use the chin strap on to fold its wide brim into not so floppy and more triangular. I’ve stuck my goTenna up there several times and with the chin strap running across the front, you can even strap your goTenna to it for extra security.
Photos or get outta here (But seriously, am curious!)
As my brother says, if there isn’t a picture, it didn’t happen…
