p language used in the WAP environment. workstation A device (e.g., display station, printer) that can transmit information to or receive information from a computer, or both, as needed to perform a job. world numbering plan An ITU-T numbering plan, E.164, that divides the world into nine zones. Each zone is allocated a number that forms the first digit of the country code for every country in that zone. The zones are as follows: (1) North America (including Hawaii and Carib- bean islands, except Cuba), (2) Africa, (3 and 4) Europe, (5) South America and Cuba, (6) South Pacific (Australasia), (7) Russia, (8) North Pacific (Eastern Asia), and (9) Asia and the Middle East. A spare code (0) is available for future use. WPA (Wi-Fi Protected Access) A wireless encryption standard that the Wi-Fi Alliance cre- ated in response to serious weaknesses in WEP. A second version of WPA is called WPA2. WPAN (wireless personal area network) A wireless network that serves a single person or small workgroup and is characterized by limited distance, limited throughput, and low vol- ume. The WPAN standards in use today include IEEE 802.15.1 (Bluetooth), IEEE 802.15.3 (WPAN-HR and WPAN-AHR), UWB, IEEE 802.15.4 (ZigBee), RFID, and NFC. WRAN (wireless regional area network) A regional wireless network being created by the IEEE 802.22 working group that is to use the UHF/VHF TV bands that the FCC is opening up for experimentation. WRR (Weighted Round Robin) A queuing mechanism that assigns a weight to each queue and then services each nonempty queue in proportion to its weight, in round-robin fashion. WRR is optimal when using uniform packet sizes, a small number of flows, and long connections. WWAN (wireless wide area network) A network that is global, national, regional scope and that operates without wires. Traditional WWAN solutions include cellular radio and PCS networks as well as early wireless data networks. Newer generations are focused on support- ing high-speed data as well as video and multimedia, with increased emphasis on
