Ronnie,

Do you have a working email address I can contact you on? The addresses in
my sig are genuine if that's easier.

Regards

Jon.

Of course there are many channels in a cell sector, but this does not change
the fact that a single channel will always have 8 physcial timeslots (even
half-rate cells operates on 8 physical timeslots per frame per channel,
expect in half-rate mode each "circuit" will transmit on every other frame).

In the infrasturture industry a BTS rack can normally accomdate several
radios (and hence several channels), but the term BTS is normally used to
discribe a single radio/channel hence leading to phrases like BTS2, BTS6
etc.

You mean not used - the timeslots are always there in the basic structure
whether they are used or not.

No, you are technically incorrect, I am sorry there is always 8 timeslots
per channel, they may not all be used for voice or data, and some may be
used for broadcast or control channels, but the timeslot structure is always
8 per frame.

As I have already stated above, HR deployment sit ontop of the 8 timeslots
per frame structure, only the TCH/H logical channels are mapped to the
physical channels by using every other frame.

Bull****. Only the clueless would say that. Oh yes, you did. Nuff sed.

Goodness, you are a cretin.

Try reading the eleventh word. It starts with a curly c, but the rest
isn't "hannel", is it? It very clearly says cell. Even the clueless
ought to be able to work out that I was talking about per cell, not
per channel.

OK, so I mistype, but further in the same paragraph I did correct myself "8
timeslot per frame".

Are you always this unpleasant? Or do you just like scoring points over a
simple typo?

This is usenet, it requires everyone to be unpleasant.

I very much object to being told I am wrong when I was completely
correct, particularly when the person telling me I was wrong is
himself wrong.

Really? Just checked the GSM Bible, which confirmed that the ETSI standards
itself is not consistent with the use of the term "Channel" - in that a
channel is also sometimes use to describe a carrier (ie a single frequency
channel) and at other times as a data or traffic channel well as . So I did
not need correct myself,

I win you lose :-)

That's what you think, clueless.

It never fails does it?
Regardless of how interesting or informative a thread might be the
abuse level always rises the longer it gets. What did we manage this
time? 17 posts before descending to the level of childish playground
name-calling, not bad by usenet standards I suppose.
How does it go?
"I didn't come here to be inslulted."
"Really - where do you normally go then?"

Think of GSM network like the WWW, the more cells the more
robust the network and generally greater the capacity

Also closer and stronger the signal, resulting in lower the handsets output

It's partially the reason. The other reason is to plug holes in
coverage.

Why do *you* think networks like to install new sites?
