Ben, maybe I was mistaken, so let's walk through the basics:
> 4+2
> 4 channels incoming
- to handset, base station transmits, yes??
> 2 channels back
- handset transmits, yes??
> 4 bonded channels incoming - requiring 4x power (resultant

> drain) - and emitting a corresponding increase in
> radiation.
Correction " ..draining)- and the base station emits.."
In case the base station runs on battery it will
obviously also drain the batteries of the base station.
(for example when the 110V is cut off)
Incredible how one get things totally wrong when not even
using a carefully planted "it" to have an intellectually honest excuse.

What's your best guess on the amount of:
- battery power, and/or
- radiated (transmitted RF) power
that it takes for a handset to
- transmit and/or
- receive
(clue, the word _transmit_. I know it is difficult to
handle 2 things, 4 words at the same time correctly, but
give it a try, practice _talking_ and _listening_ with
somebody, but avoid doing it on cocktail parties)
--
One can get a very good measure of both of these modes
(talking and listening) by comparing the standard talk and
stand-by times of a regular GSM phone.
- talking (both _transmitting_ and receiving), some 2 hours
- standby (only receiving), some 100-200 hours
Note that to be able to pling-plong an incoming call
within reasonable times the handset has to receive
and detect messages like "no incoming call" and "incoming
call" every now and then (every second).
Although there isn't any incoming call the handset still
have to listen if there is one (very important point,
difficult for some)
That is, the total receive path, RF-IF-AGC-DSP-protocol
must be up and running to check for an incoming call,
even if there isn't one, _BUT_ _NOT_ _THE_ _TRANSMITTER_!
Ilmarinen.
P.S. So once more, it is _transmitting_ which
uses, produces RF "power" to do just that, to _transmit_
(like to _talk_)
Receiving (like listening) does not "drain the battery" nor
produce high power RF signals (radiation, but not alpha,
gamma nor beta, but RF)
In 4+2 the "4" is for the handset "listening", the "2" is
for the handset "talking". |
