What Does PoCv11 Mean For Me?

Short ver­sion: Use a low gain anten­na, report your loca­tion and anten­na gain accu­rate­ly, and PoCv11 will have more or less no effect on you.

Super short ver­sion: Don’t worry.

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 checkV11 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.

  1. With­out sound­ing crit­i­cal, it’s impor­tant that peo­ple under­stand that the above relates a lot more to the US, in the UK where a good set up, LMR400 cable, roof mount­ed sev­er­al metres above your house with good line of sight will still see a RAK 5.8 reach 4–5 hex­es if you’re lucky due to the already reduced pow­er (I have 24 hotspots in a vari­ety of envi­ron­ments run­ning and have tried mul­ti­ple anten­na in mul­ti­ple loca­tions for weeks at a time so have a lit­tle expe­ri­ence) spend­ing mon­ey on a decent 8 DBI makes a huge dif­fer­ence in HNT earn­ings here, and there’s a strong feel­ing that those in the EU are get­ting hit hard for spend­ing hun­dreds on a good set up, whilst most US users aren’t both­ered so the “don’t wor­ry” com­ments are from those like­ly to be based in the US and there­fore unaf­fect­ed — an “I’m alright Jack” atti­tude and I’d sug­gest an empha­sis in the your writ­ing that it’s a US focus only.

    There’s also a lot of con­fu­sion on Dis­cord as to whether the reduc­tion in pow­er is only tem­porar­i­ly applied at the point of broad­cast­ing a bea­con and the full strength of the anten­na is still avail­able the rest of the time, or if its applied for both broad­cast and receive.

    Cor­rect me if I am wrong, but sure­ly those in the EU (or oth­er coun­tries with a low­er EIRP lev­el) can’t real­ly grum­ble about Heli­um low­er­ing pow­er out­puts so that they are with­in legal lev­els? If the long-term growth of the net­work is what peo­ple want, sure­ly hundreds/thousands of hotspots oper­at­ing over legal lev­els in a coun­try is a good way to go about get­ting it banned?
