Advanced Pager Operating Code (APOC)

Description

Advanced Pager Operating Code. A new mode, developed by Philips Telecom and announced in 1993, that offers higher speed and some new features while retaining backwards compatibility with POCSAG. Supports bit rates between 1200 to 6400 or about 1200 to 3200 baudBaud (unit symbol Bd) is the unit for symbol rate or modulation rate in symbols per second. using 2-PAMPulse Amplitude Modulation/FMFrequency Modulation or 4-PAMPulse Amplitude Modulation/FMFrequency Modulation modulation. Extended addressing is supported, allowing support for more then 2 million pagers. As of mid-1996, Philips has dropped APOC and instead settled a cross-licensing deal with Motorola for access to FLEX.
