3G Migration

CDMA2000 3G offers a viable solution for any existing cellular and PCS as well as new 3G licensed operator. CDMA2000 was designed so that any wireless carrier, regardless of existing air interface, frequency or core network standards can benefit from its spectrum efficiencies and data capabilities.

cdmaOne to CDMA2000 Migration
CDMA2000 is the natural 3G evolution for cdmaOne operators, requiring only minor upgrades to the network and small capital investment. CDMA2000 handsets are backward compatible with the legacy cdmaOne infrastructure. Because of this, the transition from cdmaOne to CDMA2000 1X is relatively easy for operators and transparent for consumers.

This inherent advantage of cdmaOne gives operators significant market advantage. cdmaOne operators lead deployment of 3G across markets in Asia, the Americas and Europe.

The transition from cdmaOne to CDMA2000 requires channel card and software upgrades to cdmaOne base stations (older base stations may require some hardware upgrades) and introduction of new handsets.

TDMA to CDMA2000 Migration
Lacking a technological migration path to enable higher voice capacity and bandwidth-intense mobile data services, TDMA has reached its limit. Thus, TDMA operators are faced with a difficult decision to choose a technology that will assure their future in the wireless market. CDMA2000 is an extremely attractive solution for TDMA operators. It offers them a direct path to3G, preserves their investment in the existing core network, and allows them flexibility to migrate to 3G over time, as the market for advanced service evolves.

Advantages of CDMA2000 as a migration path for TDMA:

  • Offers a direct path to 3G via a single evolutionary step rather than two or three upgrades required for an alternative path
  • Reuses IS-41 elements of the existing core network, providing for substantial cost savings and enabling service transparency for end users
  • Increases capacity of the existing TDMA air interface by 4 to 8 times to meet future demand for voice services
  • Requires only a small amount of spectrum (1.25 MHz) for advanced services while preserving capacity to service existing customers
  • Does not require new spectrum. CDMA2000 is designed to operate in all existing cellular and PCS bands, including 800 MHz and 1900 MHz where TDMA currently is deployed.
  • A wide range of competitively priced devices are commercially available
  • A number of infrastructure manufacturers offer solutions today

For TDMA operators in Latin America, CDMA2000 also opens significant roaming markets in the Americas. Because CDMA2000 is backward compatible with cdmaOne, the subscribers would be able to roam in 15 countries in South America, as well as with the U.S. and Canada.

Already a number of TDMA operators have selected CDMA2000 as a migration path either through cdmaOne or directly to CDMA2000.

Shosteck Group White Paper on TDMA 3G Migration Paths, June 2001
This white paper looks at both GSM and CDMA as possible 3G migration paths for current TDMA/IS-136 operators from independent analysis by The Shosteck Group. It concludes that CDMA offers a viable evolution path for TDMA operators.
