Question

Mobile development

Guys, hello!
To develop an application, I need to know how far the wifi phone takes on average.
And if someone understands, take a look, is it possible to implement such an application: allyboy.ru/iperson ?
Thank you!

Answer 1

average router ~1k rub. 30 meters (through one non-main wall) mb and establish a stable communication channel.

Answer 2

This is a highly abstract value.
In general, the range will depend on a lot of factors
- the signal strength from both sides
- the polarization of the antennas and their placement relative to each other, the design
- the electromagnetic environment
- the clogging of the channels
- working household appliances
And a lot of other factors - generally not relevant at first glance.

Answer 3

If we get lucky. More than 100 meters, I would not bet.
Also, do not forget that most mobile phones prefer to reduce the power or turn off the Wi-Fi transmitter until no application is clearly using it.

Answer 4

It also depends on the router itself, for example, my wi-fi router from Altel 4G distributes only 2-4 meters.
