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


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.

Reference: Recommendation ITU-R F.1399, “Vocabulary of terms for wireless access”

• Call for operators interest: Jan 2004

– 11 operators replied favourably

• Resolution 395– 411.675 MHz-415.850 MHz and 421.675-

425.850 MHz bands• Trunking and fixed multimedia

• Auction process is being prepared



3 G Spectrum Auction – Objectives

• Competition

– New mobile operator

• Area 1 and 2 – São Paulo• Area 10 – Northeast

• Digital inclusion

– Promote the 3 G services offer by auctioning the spectrum available in 1.9 and 2.1 GHz



3 G Spectrum Auction – 2005 Targets

• Choose one of the alternatives

• Determine the evolution on regulation existent and establish the authorisation rules

• Conduct the authorisation process

• Define the winners and sign the due authorisation
