please explain for what you need this.
With signals weaker then -90 you would not be able to transport anything serious
128kbps using a mobile device would be serious?
so why basebox 2 has a receive sensitivity of -100 at 1mbps while metal 52 ac has a receive of -97 if weaker than -90 is useless? Then the receive sensitivity is not a factor to choose between basebox 2 (tx 30dbm) , metal 52 ac (tx 31dbm) and metal 2 (tx 32dbm) regarding distance achieved using a mobile device?
disregarding the cpu mhgz of these devices for this question of course.
Sorry for the dumb question, im still begginer on this topics
