Hi Yorkie
If you do not want radio, how would you like to see data transfered and would it be just data or would like voice as well?
Just interested.
Best system would be one that doesn't tie you to only one technology.
One technology is radio. Radio is fine for a lot of people if you have a good coverage area from your base. Those who don't have good coverage need to invest in remote equipment on hilltops, landlines or wireless links. You basically spend the money until you have covered the area you need and then running costs are just your licence fee to Offcom (the old RA) each year.
Another technology is GPRS. GPRS is fine if you have large or unpredictable coverage area but you are in the hands of the big boys that run the networks - the people like O2 and Orange. Plenty places in Scotland or Wales will probably never get GPRS. Also, at present there is only so much capacity in the network as the network operators are still waiting for a more significant uptake on GPRS customers before they spend any more money on the network infrastructure.
I should also mention that GPRS is very good for small startup companies as they don't need to invest in radio equipment in order to get their drivers out and about.
So, look carefully for a data system supplier who can deliver a system that can use radio or GPRS. Look for a system that can decide the least cost routing for a data packet and automatically use radio or GPRS accordingly.
Even if you are only ever going to need to use only one technology or the other, it's also best to have a choice about what equipment to have in the vehicles and to not be tied to one particular datahead or PDA / Smartphone. Some drivers are less than carefull with their mobile data terminals so PDAs may not be appropriate for some but may be for others. You choose - chunky brick Mobile Data Terminals for simple messaging, plotting and accepting jobs with simple GPS reporting - or shiny precious PDAs for full voice guided navigation, colour maps and shiny buttons.
One last word about voice is that it is difficult to give it up altogether. I do know youngsters who will happily spend 1/4 hour composing a text message on their mobile phone to say something that would take 30 seconds to say!

But most of our generation just isn't like that. The radio solution gives you the simplest option by selecting 'voice' on your data terminal or by changing the channel on your radio and using your mic. Unfortunately, it's a little more involved with GPRS. You would need to have a seperate voice contract with the phone network in order to have a voice alternative to the data and most PDA based GPRS systems will persuade the driver to simply have his own phone for making such calls.
There you have it, my thruppence worth.
