Short version: Use a low gain antenna, report your location and antenna gain accurately. If you’re in the US, this isn’t a big deal, as our radios pump out enough power to get excellent range even with a low gain antenna. If you’re in a region (UK, EU, etc) where your radio output is low, PoCv11 will probably decrease your range significantly.

Want to read on for posterity? Cool!
PoCv11 is designed to help the Network more accurately assess location from radio frequency strength signals and to keep Hotspots in RF regulatory compliance. It cleans up a few mistakes Helium made early on in trying to assess radio signal strength in an attempt to combat gaming.
That’s it. If you are accurately reporting your antenna gain and your location, there’s no penalty and nothing else you need to do.
Normally I love to explain complicated things, but this one is so damn simple it’s hard to do better than Amir Haleem, CEO at Helium:
i’ll try and summarize what PoC V11 does:
adds regional support for PoC – today the network treats all PoC activity as if it’s operating in the US. this is a problem as different regions run on different radio frequencies and at different power levels (by law), so what is considered valid or invalid varies substantially. V11 adds regional awareness based on the asserted location of the Hotspot
removes SNR from the validity checks – today both the signal-to-noise ratio and free space path loss calculation (FSPL) is used to determine whether PoC packets are valid or not. this was an attempt to make it more difficult for gamers to lie about their location. it hasn’t worked well and is being removed. SNR proved to be fairly useless as a mechanism, so now only an FSPL calculation is used to determine whether Hotspots are where they say they are in relation to each other
adds a regional frequency check – V11 introduces a check to make sure that PoC packets are being sent at the correct frequency for the region the Hotspots are located in. for example if a Hotspot is transmitting packets in the US frequency bands but based in South Korea, those packets would now be invalid
complies with local power output regulations – different regions have different maximum power output laws for unlicensed radios. in the US, for example, the max EIRP is 36dBm. in the EU this is 16.5dBm. currently in PoC v10 the power output is hardcoded to 27dBm for the US and rest of the world, and 14dBm for the EU. V11 will reduce the power output if the combination of the maximum output power + antenna gain exceeds the local laws – for example, a Hotspot operating in the US with a 5.8dBi antenna would have a total EIRP of the Hotspot power output (27dBm) + the 5.8dBi antenna = 32.8dBm total EIRP, which is below the 36dBm allowed. nothing would change in this case. if instead the antenna was changed to a 10dBi antenna bringing the total EIRP to 27dBm + 10dBi = 37dBm, the miner software will reduce the power output of the Hotspot by 1dBm so that the total is less than equal to the 36dBm allowed by law. in the EU a 5.8dBi antenna would cause the Hotspot power output to be reduced to 10.7dBm so that the total EIRP is 16.5dBm
PoC V11 does not have anything to do with the 10 witness maximum, or the witness randomization changes that were added recently. we’re hoping to activate PoC V11 in early October. it is currently not active.
But, but, but, it COSTS MONEY to state my antenna gain! Relax, dawg. It costs 55,000 DC. That sounds like a lot. It’s not.
1 DC = $. 00001. So, 55,000 x .00001 = $.55. You can afford that.
I know you want to get all worked up about PoCv11 and how it will change things. Relax, it’s not a big deal as long as you’re playing by the rules. It’s part of Helium’s efforts to improve the network. Color within the lines (report your location, antenna gain, and elevation accurately) and PoCv11 will only make things better.
