Well sort of.
It is true that the maximum transmission wattage is limited for many good reasons:
- the lower power transmitters are less likely to blow up and so fewer fatalities
- the Internet itself is only so fast so a typical 100mW radio signal is fine for typical homes
and the radio spectrum is limited for good reasons:
- its sold, monetized by the governments, so restricting it drives its price up, something we the consumer pay for in the products
- the spectrum is kept for discrete purposes, TV, police, emergency services, etc.
Correct radio signals do interfere, but you got some techniques:
- radio signals in domestic situations drop off to the square of distance, meaning your Wifi route 5 meters from you is 4x more powerful than your neighbours’ Wifi 10 meters from you. The inverse-square naturally forgives. I understand this camera is not using Wifi but the principals mostly apply.
- Wifi has the concept of “Auto channel” and there are 3 many channel groups meaning if you leave a Wifi router, or similar technology, all to itself, it will pick a less busy channel, less interference so on average your 5 meters away transmitter is only on the same frequency as say someone 15 meters from you so your signal is 9x stronger than the transmitter on the same frequency a few doors down. This homebase product probably does something similar.
- You can also embrace newer technology, the more people who move from 2.5Ghz to 5Ghz the better, higher frequencies pass through walls less well meaning if everyone was on 5Ghz, that 15 meter away transmitter would have to pass through multiple walls and be absorbed more so the total competition is reduced, this is the ideal answer in dense housing situations, use all those walls to keep the signals near to the transmitter and no further. I doubt Anker using higher frequencies for this product as its going to behave badly through walls, so means its more vulnerable to interference from those using the same frequency in the immediate vicinity.
- those who move to 5Ghz first will get the better experience faster.
- Radio signals go in all direction, but up close they go out mostly in the direction of the right-angle to the aerial, so pointing your aerial straight up gets the signal stronger to its side, less than the above, but this effect drops off at distance and eventually becomes inverse-cube. As it does go in all directions, reflecting the signal away from where you don’t need towards where you do need it by placing a metal sheet on the side away from your home will reflect more back to your home. This last idea is the best one if its a proprietary radio signal, simply focus it at the camera.
