This accessory to the Motorola MC50 handheld terminal
provides the unit with Wide Area Network (WAN)
capability. The unit attaches as a sleeve around the
MC50 and contains the radio modem, a removable Li Ion
rechargeable battery, antenna and SIM card. The GPRS
modem is a tri-band Class 10 device capable of providing
high speed data access to a GSM network. A SIM holder is
mounted behind the removable battery. The incorporation
of the removable battery ensures that the MC50 battery
performance is un-affected by the use of the GPRS
module. The mechanical design of the module enables the
attachment to remain compatible with existing MC50
accessories such as the desktop charge cradle and the
car charger.
