• Proposal 3 of the 5GHz consultation was related to the 5.8GHz band. – fixed services with a maximum EIRP of

2W.– Band C is an ideal candidate to implement

a database showing the locations and other technical parameters of outdoor fixed service stations deployed in this band in order to help planning

Sharing with:Sharing with:

• Road Transport and traffic Telematics (RTTT) {Using up to 20MHz, 2W}.

– Distance between the FWA transmitter and the RTTT device

• DFS• TPC

• Video links (JFMG){3 channels of 20MHz

up to 40dBW}– Distance between the

FWA transmitter and the Video link device

• DFS• TPC

• Short Range Devices• 25mW

What can W.A.G do ?What can W.A.G do ?

• Help the RA by creating realistic scenarios of possible FWA use.– P.MP– Mesh – P-P

• Sharing analyses with existing users of the band. Expertise in all systems are here!• DFS test at the RA’s laboratory.

• Upon completion of the sharing analysis suggest ideas on the IR 2007, online registration...
