I'm the current goTenna Mesh range record holder, AMA!

Hello everyone! I am George and have been doing GoTenna Mesh beta/alpha testing for the last six months and it’s been one heck of an awesome experience (not just skydiving! Most beta/alpha testing takes place on the ground and trust me the footage from that process is NOT at all as glamorous as the skydiving videos are. However both are just as fun!!!) . I’m also the current GoTenna Mesh range record holder (23 miles! Woot woot!). How did I end up jumping out of perfectly good aircraft with GoTenna!? Good question, I’ll let this interview by Nick Baker (The awesome GoTenna logistics coordinator) tell that story in the link below). So: Ask me anything!

PS: In my profile pic you will see a Gotenna Mesh unit attached to the front riser of my canopy (parachute) and heck yes my canopy (parachute) just so happen to be GoTenna colors :wink:

Added 7/26/2017: Here is the entire GoTenna Mesh record setting skydive, from start to landing. I hope you enjoy the video. I also need to thank the GoTenna app for saving my bacon on this jump. I could not see the landing area through the clouds, darn good thing for GPS and their map app having a quick refresh rate!..


I really enjoyed reading about your skydiving adventures, George! Thanks for sharing them. What do you think it’ll take to break your current 23 mile record?


Heya George: Just to clarify - the 15 mi range record in the blog post was with the firstgen GoTenna? And the 25 mi record is with Mesh? Wow.

Can anyone explain to me why the Mesh is performing potentially better than v1? I know it emits half the wattage (1 W v 2 W) but presumably it has a better antenna since it can be smaller?

Either way as a firstgen GoTenna user this is very exciting! Just got my Mesh devices but haven’t used them outside of our backyard yet. Can’t wait

EDIT: Fixed typo

  1. Was 23 mi the range limit or is that just how far the other goTenna Mesh user or unit was when you were falling to earth at who-knows-how-many miles per hour?

  2. What kind of point-to-point range have you been getting in regular (not flying out of the sky) situations with goTenna Mesh?

  3. Same as question #2 except, with meshing? (i.e. You were getting Y point-to-point but with meshing you got X.)

  4. Are you like that guy that just scaled El Capitan without harnesses and missing fear receptors in your brain? :wink: (Just kidding, sort of.)


@femmesh, great question! I’m Jin, one of the RF Engineers at goTenna, and am excited that someone finally noticed the apparent paradox and asked about it. You’ve actually already answered 90% of the question - it’s mostly the antenna.

If you are not aware already, goTenna MESH uses the 915 MHz ISM (Industrial, Scientific, Medical) band in the US, while goTenna V1 uses 152 MHz MURS (Multi-Use Radio Service) band. The ideal, not miniaturized, antenna length for 915 MHz is around 3 inches, while the ideal length for V1 is around 19 inches! As you can imagine, the trade-off of miniaturization technique used for MESH antenna is much more forgiving than V1.

In addition, we took the steps to integrate the latest and best performing Low Noise Amplifier (LNA) in conjunction with proper filters on MESH receiver chain that improves sensitivity in a low noise environment. Finally, we took full advantage of the much wider authorized spectrum of tens of MHz in MESH vs tens of kHz allowed on MURS to implemented a more resilient custom communication protocol that is capable of automatic retransmissions across much more channels.

So even though V1 is more powerful than MESH in transmit power, the MESH makes up for it by everything that is described above during George’s daredevil test (BTW, I prefer to carry out my tests with my feet safely on the ground :slight_smile:).

However, I want to point out that V1 has moments that outshines MESH! Since the ISM band is a widely used spectrum by the wireless community, it could be densely occupied and noisy. In such environments, the narrower and higher power V1 will likely to outperform MESH, but in general, we foresee MESH to be the stronger of the two.


@Jin_Gotenna thanks for your very complete answer! You taught me a few things!

Thanks Michael! First a little background: Being up at 10,000+ ft gives me awesome radio line of sight. When I exit an aircraft I do so from about 15,000 ft AGL (above ground level) and by the time I have canopy (parachute) open and my GoTenna up and running I am about 12,000 ft. At 12,000 ft I have 134 miles of radio line of sight and at 5,000 ft (the altitude I start to focus on where I am going to land) I have 86 miles of radio line off sight. The short answer: What I need to break my current record is someone more than just 23 miles away from me while I am in the air, when we got this result I only had someone 23 miles away, thus the record was only 23 miles.

Again, thank you for your kind words and I am so happy you enjoyed reading about my GoTenna skydiving adventures, it was nothing short of amazing being able to do make those jumps! And of course: There is more to come :slight_smile:

Hey @danielagotenna, well…

  1. It was technically 23 miles (that’s what the GPS told us and was backed up by checking an aviation map that shows a straight line between two points. Under canopy (parachute) I only was falling at about 10 MPH and during this test I opened my canopy (parachute) right when I left the aircraft (also known as a “high pull”) thus maximizing time spent higher up in the air in order to test Gotenna Mesh. Terminal velocity is also dependent on body position! When I fall facedown I fall at about 120 MPH, when I go feet or head down I’ve hit over 200 MPH (I think it was 216 MPH to be exact). Terminal velocity is not a number, it just means you can’t fall any faster given your current situation / body position.

I know during this test it took me at least 17 minutes (likely longer) from the time I left the aircraft to landing on the ground. A regular skydive goes like this: Leave aircraft, fall for 60 second open at 4,000 ft and enjoy 3-4 minutes under canopy (parachute).

  1. In regular situations we’ve been getting 1/2 to 4 miles of range between point to point users in a hilly suburban area with lots of trees and houses around. Range of course is going to be dependent on what’s around you (trees, buildings etc). For example if you’re inside your house your range is not going to be near as good as if you were outside. Also what your house is made of plays into it as well! Wood is going to allow RF to travel a much greater distance than let’s say brick. Oh and how can I forget your elevation in relation to other users. So many factors play into radio range! I do also know that GoTenna Mesh performed as well and in some cases better than the hand held UHF radios were using as a comparison.

That’s why we test under canopy (parachute), it gives us the perfect environment for long range clear unobstructed performance testing. It’s also a whole lot of fun!

  1. I don’t know this off the top my head but I should! I know while testing we were really focused on getting Mesh meshing perfected. I will look into this tonight and answer back.

  2. Oh I have fear receptors and they work, sometimes to well even. I have fears and feel fear just like everyone else, in fact I am scared of a lot of things come to think of it. I just got used/good at jumping out aircraft and a bunch of other things some might consider scary. In the medical field we don’t run from disease, actually the opposite: We run towards it and study the heck out of it in order to understand it so we can’t beat it. The above sounds scary and was at first however with knowledge/understanding, training, and knowing you can trust your equipment allows you to fully enjoy the experience because what was once feared is now understood. The fear melts away and you find yourself falling to earth in a highly aware zen like state where you’re only focused on the task at hand, it’s kind of a form of meditation now that I think about it.

Thanks for reading I typed this on the bus ride home so please forgive any typos!



I think Jin answered this question way better than I could have! Thanks Jin!

The answer is 3.3 miles using two people and two mesh units set up as relay nodes, however on this test we were heavy into evaluating Mesh reliability not testing out max range hops. We should do that next! In this test we were in a suburban area with lots of hills, tress, and houses in the way. Basically getting in ideal locations to make the units Mesh, this does not reflect results you’d get out hiking or other outdoor activities.


The record setting GoTenna Mesh skydive: From start to landing…


Hardly beat your range this weekend, George, but tried meshing outdoors. Very cool:



@femmesh I think my range record in the air MIGHT be outdone on the ground!


Yep! HOWEVER! To be fair I think they would be about the same. More extreme range testing to come! Gotta do it to find it out!

A little bird in public safety told me they saw goTenna Mesh at a military demo, mounted on a drone, hit closer to 30ish mi… goTenna team, is this true?


My cofounder literally told me this is the case yesterday. Are you in cahoots? :wink:

@gua742 you’re gonna have to jump out of a plane again… hard life! Haha


I can beat that range!

This message has been sent from George’s iPhone. If you need to reach him right away please call or text (206)-488-8987

Thank you.


What was the altitude of the drone? I’ll have to test this one out myself as well using my drone. On my list to do for sure! This is awesome.

Would there be any interference/issues having a gotenna mesh secured to the aircraft (drone)?


I am not sure we know the exact altitude, but this record was achieved at a public safety demonstration so they were probably using pro-level (i.e. non-consumer) drones, is my best guess.

@Rahul_Subramany Do you know the answer to this?
