Just now I came to know one more wireless technology called CDPD (Cellular Digital Packet Data) runs on AT commands and UDP. Sounds similar to GPRS? Is this the name for Qualcomm's equivalent of GPRS? Distance coverage: 30 Miles If you use the public cellular service (whatever it may be) distance is irrelevant - it's just a question of whether or not you have coverage at all the necessary locations. As Erik says, cellular coverage inside buildings (especially industrial, steel-framed buildings) can be very trick... Try putting "M2M into your favourite internet search engine - short for "Machine-to-Machine" |
