	CDMA2000 - Wikipedia, the free encyclopedia
		It is the second generation of CDMA digital cellular.
		CDMA (code division multiple access) is a mobile digital radio technology that transmits streams of bits and whose channels are divided using codes (PN sequences).
		In Indonesia, Mobile-8 is the major mobile wireless service provider on CDMA 2000 1x (with EVDO in Western Java).

	GSA opposes TRAI's mixed band proposal
		IMT-2000 supports both Wide-band CDMA (GSM path to 3G) and CDMA 2000 (CDMA path to 3G) systems developed for deployment on a fully co-existing basis, thus ensuring all operators and users benefit from 3G for enhanced voice and data services, the largest scale economies and international roaming, it said.
		The IMT 2000 core band is standardised to accommodate both WCDMA and CDMA 2000 technologies, and there are no harmful interference mechanisms between the two technologies when deployed in the IMT 2000 core band, Alan Hadden, President, GSA, said.
		CDMA equipment suitable for use at 1800 MHz is widely available commercially in Korea from several infrastructure suppliers.

	Quality of Service for Multimedia CDMA
		CDMA is a multiple access scheme where the terminals transmit continuously and together on the same frequency band.
		Multicarrier CDMA is a form of CDMA where the spreading procedure is applied in the frequency domain rather than in the time domain, as in DS-CDMA.
		The limits in CDMA capacity are determined by the MAI that is generated at the base station by all the uplink signals transmitted by users, in either the same or other cells.

	Satellite UMTS/IMT2000 W-CDMA Air Interfaces
		CDMA full frequency reuse permits reverse link satellite antenna arraying (similar to deep space ground reception techniques) whereby the different replicas of the same signal transponded by the different satellites are independently demodulated, time aligned, and coherently combined at the gateway station.
		Note that in a CDMA system it is possible to use very-low-rate codes without diminishing the spectral efficiency, since the coding rate contributes to the spreading process.
		One example is the Prioritized Packet Reservation CDMA (P2R-CDMA) protocol for the uplink in a multicode CDMA system, which employs centralized frame-based slot reservation along with dynamic slot assignment in the base station using the QoS-oriented dynamic priority of an individual terminal.
