No.1 benifit in my view is coverage and bandwidth.

# 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. QUALCOMM's CDMA variable rate vocoder translates voice into digital transmissions, zeroes and ones, at the highest translation rates possible (8kbps or 13kbps). This allows for crystal clear voice and also maximizes your system capacity.
# Greatest Coverage for Lower Cost
CDMA's spread spectrum signal provides the greatest coverage in the wireless industry, allowing networks to be built with far fewer cell sites than is possible with other wireless technologies. Fewer cell sites translates to reduced operating expenses, which results in savings to both operators and consumers.
# 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
You can leave your phone on with CDMA. CDMA uses power control to monitor the amount of power your system and handset need at any time. CDMA handsets typically transmit at the lowest power levels in the industry, allowing for longer battery life which results in longer talk time and standby time. 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 cells sharply reduces the risk of disruption or dropped calls during a handoff. The process of soft handoff leads to fewer dropped calls as 2 or 3 cells are monitoring your call at any given time.
# Improved Security and Privacy
CDMA's digitally encoded, spread spectrum transmissions resist eaves dropping. Designed with about 4.4 trillion codes, CDMA virtually eliminates cloning and other types of fraud.
# Greater Capacity
CDMA allows the largest number of subscribers to share the same radio frequencies, helping service providers increase their profitability. 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. Both electrical background noise (computer noise) and acoustic background noise (background conversations) are filtered out by using narrow bandwidth which corresponds to the frequency of the human voice. This 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 Advances
CDMA technology enables users to access a wide range of new services, including caller identification, short messaging services and Internet connections. Simultaneous voice and data calls are also possible using CDMA technology.
