This is going to sound really dumb but i have found in my few years working with mobiles that most people dont really know how to get the best performance from there mobile, in fact often a few simple changes in habbits, storage and use can make the difference between recieving and not recieving calls.

Any way here are a few tips until i finally sort a blog.

*When your mobile is next to your skin it loses between -5 & -15dbi which in poorer signal means often calls will go to voice mail etc. How to fix, to improve this whilst having the phone on your person don't leave the phone in your pocket instead get a holster or leave it in a bag etc. This will lessen the effect that your body has on signal , i have done some unscientific tests and it can improve the signal to within a few -db to what the phone would be away from your body .

*If you are sitting or at work at a desk leave the phone on your desk away from your PC, this will obviously ensure your phone will recieve at optimal level for indoor (the best signal in the location). Often people leave phones in their pockets at work and wonder why when they are in average to good coverage why the calls often go to voice mail. It's your skin!

*In the car if you can't get an external antenna connection (several passive holders available with antenna connectors) purchase either a windcreen mounted holder or find a way of mounting the mobile on the top of the dash of the vehicle. The majority of users leave their mobile on the seat, centre consol etc and again wonder , why when travelling using blue tooth or not using bluetooth, they often miss calls. The dash and vehicles walls absorb a huge amount of signal. Average loss is between -5 & -15dbi which again is huge and makes a big difference. Simply by installing a top of dash plastic mount or windscreen mount has improved my call holding capability. Very rarely will i not have clipping unless i am really in poor coverage.

*Use blue tooth with the phone in a mount in car as above and when at the office leave it on your desk again to get the best performance for coverage

*when holding the phone in your hand unless the antenna is on the bottom of the handset hold the phone in the bottom half of the phone to avoid skin RF shrowding. Razors and Sanyo 6600 handsets with bottom mounted antennas should be held in the top half of phone again to avoid shrowding.

Any way there a couple of things to think about, most people have no idea of how to handle a mobile and simple basic handling techniques might just avoid poor performance. Any way do with this what you want. Hope it helps

All these people whom engulf the entire top of the phone with their hands and wonder why the handsets get hot or the other person cannot hear them is just idiotic.

Also remember that holding the antenna away from any body or sheilding also improves battery life considerably.

Look at my avatar, that's a 3GHz Spectrum analyser with some bad harmonics.

Simple and basic principals of use would save Networks and retailers a lot of hassels if they actually gave some use full basic instruction the numbers of poor performing phones and un happy users would decrease dramatically.

Telecom gave some great advice about 10 years ago on their TV ads. If you're in a poor coverage area standing on top of your caravan can work wonders! :-)

And don't leave your phone next to your mouse cable - however if you do you can use the fact that your mouse cursor has just gone nuts to deduce the fact that any second your phone will start ringing...

Not that I've actually done this... Embarassed
