PD (POCSAG Decoder)
PD, together with a receiver or scanner, allows the off-air decoding of POCSAG paging signals at 512, 1200 or 2400 bits/second. This makes it extremely useful for the testing of paging transmitters and systems. Decoding of both numeric and alphanumeric pager data is supported, as is the hex dumping of raw POCSAG codewords.
P_Base Version 1.00
For users of PD.exe, the DOS POCSAG decoder, a Windows based companion database shareware program is now available for evaluation.
Pager DataScope
This commercial grade unit emulates the logic on the pager's microcomputer pager board and adds complete control of the demodulated signal. We have extensively tested the Pager DataScope, with the help of server pager service shops, with DOS 6.2 and Windows 95 - all on a standard 386/486 PC.
Paging Protocols
By Jay Moskowitz, Real Time Strategies -- A protocol is a set of "rules" that govern the form, format, data content and information flow sent over communication links that connect different devices. Put simply, a protocol is a computer "language" for communicating information. Paging networks use a wide range of protocols to provide communications between different network components. Each protocol has a specific purpose but, in concert with each other, they support all of the features and services that the radio common carrier (RCC) wishes to provide. Some protocols that have been developed are specific to a particular manufacturer's set of equipment, while other protocols have become industry standards.
POCSAG Encoding and Decoding
Have you ever wondered what all that horrible noise you hear on your scanner radio is? Well it's POCSAG. POCSAG is a data transmission system used for sending messages to personal pagers.
The POCSAG Paging Protocol
The basic signaling pattern used in many pagers is a sequence of coded binary data using the Post Office Code Standardization Advisory Group (POCSAG) code. The POCSAG code is a synchronous paging format that allows pages to be transmitted in a single-batch structure. The POCSAG code provides improved battery-saving capability and an increased code capacity.

The Purple Pager
Consumer Electronics Class EE 498 -- Spring 1995 Final Project Report at the University of Washington. The goals of the project were: Detailed description of the paging transmission system and an individual pager, Study of the signal and any signal processing techniques involved, Design and assembly of a transmitter that activates our pager, and Modification of a pager to create a `page tracker'.
