Whats the deal with CDPD and GPRS?
The main advantage of using a public data network such as CDPD or GPRS is that you do not have the up front costs of building and maintaining your own wireless network. There are monthly reoccurring costs that average $30 – $50 per month per vehicle, though. CDPD and GPRS networks are owned an d operated by the cellular phone companies. As such, the coverage is typically limited to major urban areas. Another significant advantage of public packet data networks is the tremendous bandwidth they can support. The real time data volume of a 1000 vehicle fleet can easily be handled by CDPD technology.
