Code division multiple access (CDMA) is a form of multiplexing (not a modulation scheme) and a method of multiple access that does not divide up the channel by time (as in TDMA), or frequency (as in FDMA), but instead encodes data with a special code associated with each channel and uses the constructive interference properties of the special codes to perform the multiplexing. CDMA also refers to digital cellular telephony systems that make use of this multiple access scheme, such as those pioneered by Qualcomm, and W-CDMA by the International Telecommunication Union or ITU.

SIP Trunking Is Key to Accelerating Unified Communications Deployments
published by Sprint on Oct 16, 2009
Companies today are undergoing a significant transformation to a more global Anywhere Enterprise. Unified communications (UC) is a crucial component in this evolution and organizations look to collaborate better with an extended enterprise (see Exhibit 1 on the next page). UC has the power to help companies lower the overall cost of communications, bring worker productivity to new levels, enhance corporate green initiatives and completely redefine the way we work by becoming part of our application infrastructure.
Simplicity, Efficiency and Transparency Achieved Through Integrated Wireline and Wireless Services
published by Sprint on Oct 16, 2009
As enterprises recognize the strategic importance of enabling their remote and/or mobile workforce with mobility solutions, they need to determine how to best extend their existing wireline services into the mobile environment. Today, many service providers offer converged solutions that help businesses bring together their office-based telecom solution with their mobile environment.
True Convergence Demands a Communication Service Provider that Embraces a Customer- Centric Approach
published by Sprint on Oct 16, 2009
Reaching tight alignment with these objectives is not an easy task. Yet, we believe when a communication services provider integrates these customer-centric objectives into the design of its converged solution, its business customers will no longer ask if the solution will meet their objectives. Rather, the question becomes one of execution: how and when to move to a converged communication solution. converged solution. From these attributes, a framework to measure and compare providers' converged solutions emerges. We will conclude with a review of Sprint's approach to offering true convergence to business and government customers.
