| There are many reasons CDMA is the technology of
choice for next generation digital wireless communications products
and services: |
|
- 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.
- Continuing Technology Advances
The world's most advanced digital wireless technology, QUALCOMM's third-generation
CDMA is also the standard for the wireless industry. This flexible standard
functions in three modes -- Multi-Carrier, Direct Spread, and Time Division
Duplex -- and operates with ANSI-41 and GSM-MAP networks. With CDMA
as the industry's single 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 products cost curves resulting in lower costs
for both operators and consumers.
