TRW-24G Range

Wireless & IoT
1

Hi!,

Well I finally have something working! I set RF Power to Max (0db)

and my address is set to 8 bits. Since my current range is

30-40 meters a far cry from the specd 280 meters :? Has anyone

actually achieved 100-150 meters 100 % of the time with the TRW-

24G module? If so how was it configured? I’d say in my test works

70% of the time. Below is part of my config settings any suggestions

would be appreciated.

I havn’t tried it but I know you’ll over double your distance by lowering the bitrate to 250kbps since the sensitivity increased by 10 dB’s

Hi,

I have achieved 100-150m with TRF/W-24G with line-of-sight and speed of 250kbps, with packet loss = 0%. But when I put my hand near one transciever, some packets do get lost :x

Without line-of-sight the range is about 30-40m maximum…

What about building RF amplifier? 8)
