Hardware Environment
This chapter describes the hardware characteristics of the Motorola T720 handset. Use it
to understand the hardware environment in which your software will operate.
Hardware Overview
The Motorola T720 mobile phone represents the latest generation of 2.5G capable mobile
phones from Motorola. For domestic USA and European markets, the Motorola T720 uses
GSM/GPRS wireless communications. The Motorola T720’s built-in J2ME™ environment
executes the Java™ applications that you write and customers download to the phone.
For Asian and South American markets, a version using CDMA is available that uses
BREW to write and support applications.
Supported Networks
The Motorola T720 handset supports these networks:
• GSM 900/1800 (EMEA)
• GSM 850/1900 (Americas)
• GPRS (General Packet Radio Service) packet data
• CDMA 800/1900 and 800 AMPS TriMode (Asia, S. America)
• CDMA 1XRTT
GSM Networks
The Motorola T720 uses GPRS wireless technology (in the US and European Union
versions) to manage voice calls and transfer data. Four channels are allocated for
downstream data, and one channel is dedicated to upstream data. This gives the
Motorola T720 a theoretical download rate of 54 Kbps and a theoretical upload rate of
13.4 Kbps. These rates will vary according to the network operator's channel allocation
and the signal quality.
