QAM RF Demo with 2 PE0002 Hosts
When the original QAM + RF YouTube video was created, our evaluation board recommendation for customers consisted of one PE0002 host. Since that time our customer recommendation for QAM + RF evaluation boards has evolved into using two PE0002 hosts. Consequently, the original video has been updated to reflect operation with two PE0002 hosts.

‘Starman’ Multiplexing Communications Unit Utilises CML Microcircuit’s Data Modem Design
In-Taxi dispatch control systems have traditionally consisted of mobile data units, which exchange dispatch information with the central office using Public Mobile Radio (PMR). Although GPRS can be used as an alternative communication solution, PMR remains the preferred solution as it offers more reliability in a localised area, and is more cost effective for medium and large scale fleets. In such fleets, PMR is used as the primary method of data...
