I know telstra says things like 'Recommended for rural handheld coverage outside regional centres and towns.' but is there a techincal specification that can tell you how far a phone can recieve a signal or send a signal?( some way to guage between diferent mobiles)
Cheers and thanks
Graeme

No there isn't - far too many variables in the equation for simple analysis I'm afraid :(

And you can get a "Force" brand crade for the 6120 with an inductive enxernal antenna connection to get better reception still.

I use bluetooth to connect to the PC.

Works well.

Those things tend to be carefully kept away from public eyes Graeme, although I have seen some.

Its pretty straightforward to begin with things like the noise figure of the front end , but going a bit along the line of Mikes reply algorythmns (never could spell that) can make a difference of 2-3db in the effective performance of the units.

It is however practical to set them up side by side and do practical tests , with things like a spectrum analyser ,in a site out of range of cells so that the units don't talk to the base and negotiate down the power levels.
I have previously performed such tests but not on the current range of mobiles.

On less controlled side by side tests we borrowed or friends phones I have concluded the following

1/ Telstra 165
2/ Nokia 6120 (have not tested N95 which is meant to be good)
3/ A412.
.
.

4/LG 550 types


My own choice for other user reasons as well was A412 and external aerial as required.

Hi Mike - Your to subtle for me whats the question mark ?


Hi Pyro

On the various tests I undertook the Samsung A412 (a pre-paid version of the Telstra A411) had very good sensitivity and range even though it was not the best.

But it has reasonble size text, buttons and sound output (if you hold it right)

I need those magnifying glasses for close up but don't need any normally and this means that I cannot use phones like the excellent 6120 without putting glasses on and being very careful with the fingers.

The operation of the A411 , a flip phone is very simple, and in fact all you need to do to answer or close a call is to open the phone which doesn't require glasses or selecting a button.

I brought a 6120 for other family members, and while a good phone I found that a call would ring out before I finally got to answer it, or that a button would accidently get pressed.

Unlike the 6120 the A411 does have an external antenna socket at the rear. To use it you need to buy two things , an aerial and a connecting lead. They are standard acessories, and I could come up with model numbers if required.
The aerial I brought is a short magnetic base one which I stick to the cars roof as required.
I also have a vertical one about a meter long left over from CDMA days as aerials for CDMA can be used on NextG .

In practise an external aerial is not required very much, and its a slight pain to have to plug it in and out.

On a recent camp trip to a place called Coburn pines , phone signal was cutting in and out at camp. 20 ft up a nearby tree signal was better than external aerial so we wrapped phone in plastic bag and tied it to a branch. If a call or better, a text , came in, we would hear it ring as it has a loud ringer and answer it at our leisure.

I brought both of mine off the net for something like $35 total.

We were issued with the ZTE Telstra 165 at work when they were released. Great phone with great battery life and out perform all others for range. Comes with good belt clip. Screen is easy to read and menus functional. When contract up on the wifes phone will get her a 165. On jobs my phone rings and others say there is no phone coverage here, but the 165 works.
