Course 514: Binary Runtime Environment for Wireless (BREW) Fundamentals

TDMA (also known as D-AMPS) is a technology for digital transmission of radio signals between, for example, a mobile telephone and a radio base station. In TDMA, the frequency band is split into a number of channels, which are stacked into short time units, so that several calls can share a single channel without interfering with one another. TDMA is used by the GSM digital mobile standard.

TDMA is based on the IS-136 standard. It is one of the world's most widely deployed digital wireless systems. It provides a natural evolutionary path for analog AMPS networks, offers efficient coverage and is well suited to emerging applications, such as wireless virtual private networks (VPNs), and is the ideal platform for PCS (Personal Communication Services).

This course provides you with a comprehensive business and technical foundation in TDMA networks, services and applications development.
