Model Forum / Radio Controlled / Air Models / November 2007Cell phones packed together
Does anyone know if there would be a problem using cell phones to transmit and receive data if 8 phones are closely packed together? Thanks, Goan > Does anyone know if there would be a problem using cell phones to > transmit and receive data if 8 phones are closely packed together? > > Thanks, Goan could be. Transmitter of one might overload the receiver of another..but maybe they sort themselves out and wait for each to speak. I never figured how you can have a sensitive receiver in the same band as a 500mW transmitter sharing the same antenna..so its possible allright.. >> Does anyone know if there would be a problem using cell phones to >> transmit and receive data if 8 phones are closely packed together?

An odd question. Especially when asked here. ... | > 45mhz between TX and RX IIRC on a cell phone Depends on the cell phone and the bands used. Could be more, could be less. It's also quite likely that digital cell phones (i.e. anything modern) generally don't transmit and receive at the same time -- they'll transmit for a few miliseconds, then receive for a few miliseconds, etc. | Not a lot at a gig tho, is it. 45 MHz seperation at 1000 (or whatever) MHz is quite a lot, actually. It's not like you'll require the big duplexers a 2 meter ham radio repeater needs for the 600 KHz seperation.  SignatureDoug McLaren, dougmc@frenzied.us Things have taken a turn for the surreal. |
