DEFINITIONS
Seminar on Broadband Wireless Access (BWA) Brasília, May 23-25 2005
wireless access end-user radio connection(s) to core networks.
fixed wireless access wireless access application in which the location of the end-user termination and the network access point to be connected tothe end-user are fixed.
mobile wireless access wireless access application in which the location of the end-user termination is mobile.
nomadic wireless access wireless access application in which the location of the end-user termination may be in different places but it must be stationary while in use.
broadband wireless access wireless access in which the connection(s) capabilities are higher than the primary rate (i.e. >1 544 kbit/s).

ASPECTS OF WIRELESS ACCESS
Seminar on Broadband Wireless Access (BWA) Brasília, May 23-25 2005
Mobility capabilities of the terminal– fixed, nomadic, mobile, restricted mobility (e.g. within a single cell), etc.
Service support capabilities– narrow-band, broadband, multimedia, etc.
Type of telecommunication service– conversational, distribution, information retrieval.
Connectivity– e.g., Internet, PSTN, etc.
Radio transmission technology– access technique (TDMA, CDMA, etc.), modulation technique (analogue,
digital, etc.), duplex technique (FDD, TDD, etc.), etc.
Delivery mechanism– terrestrial, satellite, etc.
