The idea of tetra is a grand one, I worry however that intergration will be a nightmare. The ambulance service needs far more communication than other essential services. Where I work we have a compleate mix-match of devices: . Faxing of ECG's to CCU's (over GSM mobile network) . Terrafix Status and text Communication . GPS Tracking and Navigation . Electronic patient report forms . Mobile Phones on each vehicle . Crews own phones (because vehicle phones are naff) . VHF radios on all vehicles in constant use (and poor reception) . UHF handsets for major incedents Combine all this? in one handheld? Nation wide? IN THE NHS? not likely..... Do you worry about health risks associated with Tetra as a potential carrier of electrical emiting device on your shoulder? Could a case come where Ambulance services were neglegent to possible side effects of Tetra where it could be blamed for illness? Were supposed to be one big intergrated NHS now, Online Booking of appointments, electronic nationwide records, etc.. etc.. Will it happern? Nope!
