| 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.
