Wireless Communications Specifications

Wireless communications specifications change rapidly. Fortunately, it is rare that old spectrum is reallocated, so although much of this data was originally obtained from Data obtained from the Philips "2001 (& 2002) Worldwide Wireless Telecommunications Standards" chart, it is still valid.
