Synopsis of AUSPI’s stand


Present allocation in 800 MHz for CDMA – Not sufficient for multiple operators.

Internationally allocation for large operators varies from 10+10MHz to 20+20 MHz (average allocation 15+15 MHz).

CDMA operators need additional allocation in other bands to grow their networks.

Globally, CDMA systems work in 800 MHz and 1900 MHz, with the exception of Korea
– Korean PCS is unique and is not used anywhere else in the world.

AUSPI has proposed service neutral plan of 800 MHz and 1900 MHz for CDMA and 900 MHz and 1800 MHz for GSM in line with international standards.



Main points of NOKIA’s presentation – contd…


There is no incentive for a CDMA2000 operator to invest in filters
Experience of “mixed” CDMA/GSM in 800/900 MHz in India/Asia show that CDMA operators neglect additional filtering
Operators do not coordinate in practice

Adequate protection of the CDMA downlink Interference from IMT-2000/
WCDMA User Equipment (UE) and USPCS CDMA UE is not possible
This will result in a USPCS CDMA capacity loss up to 35%
