The CPE510 transmits relatively far. However, the counterpart must also be able to send back.
The CPE510 will send 100m without problems, but a mobile phone, for example, will never be able to answer back 100m.
If I shout something to a person 100m away, they can understand it.
However, I will not understand the person if they only speak normally and do not shout back =)
Some people's ears (comparison of WLAN reception power) may be better or worse, but they still won't hear anything at 100m when speaking normally (comparison of transmission power of CPE510 / end device, e.g. mobile phone).
