The really technical details in everyday language can be read at http://electronics.howstuffworks.com/cell-pho ne.htm

On that link you can read about the TDMA/CDMA/GSM/FDMA standards etc and get a really good breakdown of the differences. I won't spoil the experience of letting you read for yourself trying to detail things here.

I will copy & paste from the Cellular South website:

What is CDMA?
CDMA stands for Code Division Multiple Access. In plain English, it means many users can occupy the same time and frequency allocations in a given space. CDMA assigns unique codes to each communication to differentiate it from others in the same spectrum. In a world of finite spectrum resources, CDMA enables many more people to share the airwaves at the same time than do other wireless technologies.



CDMA Features:
Outstanding Voice and Call Quality--

CDMA filters out background noise, cross-talk, and interference so you can enjoy crystal-clear voice quality, greater privacy, and enhanced call quality.

Greatest Coverage for Lower Cost--

CDMA's signal provides the greatest coverage in the wireless industry, allowing networks to be built with far fewer cell sites than is possible with other technologies. Fewer cell sites translates to reduced operating expenses, which results in savings to both consumers and operators.

Packet Data--

CDMA networks are built with standard IP packet data protocols. Other networks require costly upgrades to add new data equipment in the network and will require new data phones. Standard cdmaOne phones already have TCP/IP and PPP protocols built into them.

Longer Talk Time, Longer Battery Life and Smaller Phones--

CDMA handsets can also incorporate smaller batteries, resulting in smaller, lighter-weight phones. Easier to carry. Easier to use.

Fewer Dropped Calls--

CDMA's patented "soft handoff" method of passing calls between cell sites sharply reduces the risk of disruption or dropped calls during a handoff. The process of soft handoff leads to fewer dropped calls as two or three cells are monitoring your call at any given time.

Improved Security and Privacy--

CDMA's digitally encoded transmissions resist eavesdropping. Designed with about 4.4 trillion codes, CDMA virtually eliminates cloning and other types of fraud.

Greater Capacity--

CDMA uses spread spectrum technology which can provide up to 10-20 times the capacity of analog equipment and more than three times the capacity of other digital platforms. With dual-mode phones, CDMA is compatible with other technologies for seamless widespread roaming coverage.

Reduced Background Noise and Interference--

CDMA combines multiple signals and improves signal strength. This leads to the near elimination of interference and fading and keeps background noise out of your conversations.

Rapid Deployment--

CDMA systems can be deployed and expanded faster and more cost effectively than most wireline networks. And because they require fewer cell sites, CDMA networks can be deployed faster than other types of wireless networks.

Wide Product Selection

QUALCOMM has licensed CDMA technology to over 65 leading communications manufacturers worldwide, enabling service providers and customers to choose from a wide range of highly advanced, cost-competitive, CDMA-based products.

Continuing Technology Advances

With CDMA as the industry's superior standard, carriers across the globe benefit from greater choice in equipment, lower prices, and the ability to deploy equipment and services faster than ever before. Next generation products can benefit from current product efficiencies resulting in lower costs for both operators and consumers.
