About Digital PCS

What is Digital PCS?
Digital PCS is the most advanced wireless technology on the market today. And IT&E, exclusively, is bringing it to the people of Guam. Digital PCS is a dependable, integrated, efficient, convenient and powerful communication service that gives you superior clarity, and excellent resources. Digital PCS networks are 100% digital and offer customers more choice and new services. Because of its greater capacity and digital technology, Digital PCS calls are superior in quality to traditional cellular.

What is CDMA?
Code Division Multiple Access or CDMA was originally used by the U.S. military, but today has evolved into a commercial product that supports more wireless traffic at one time that any other wireless technology. Instead of time-slotting, CDMA employs a 'spread spectrum' technique that uses the airwaves more efficiently. This also provides better signal performance, reducing the fading, echo and delay that plague some wireless sytems. So the bottom line is that more capacity means almost no dropped calls or busy signals. And better signal performances means better voice quality.

How does CDMA Work?
CDMA uses the spread spectrum technique and gives each call a unique digital code. This enables several conversations to use the same radio frequency at the same time. The unique code keeps the calls separate and secure. Each conversation is spread out over the shared channel's bandwidth allowing transmissions with the same codes to be reassembled into a conversation. That's why, with CDMA, there's virtually no eavesdropping, cloning or cross-talk.

What are the benefits of CDMA?
Increased Capacity - With CDMA, the IT&E Wireless Digital PCS Network provides a system capacity that is 10 - 20 times greater than analog systems. This means virtually no dropped calls or busy signals.

Virtually no background noise or interference - Only CDMA uses a special receiver to combine multiple signals and improved signal strength. This eliminates interference and fading altogether. Background noise is filtered out by using a narrow bandwidth that corresponds to the frequency range of the human voice.

Longer Talk Time - CDMA has power control, so your phone only uses the amount of power it needs at any given time. CDMA phones use less output power than analog cellular phones. And lower power requirements mean smaller, lighter phones with more talk time and longer standby time.

Security and Privacy - with 4.4 trillion code combinations, there is less chance of eavesdroppping, cloning or cross-talk.

Almost no dropped calls - Other wireless technologies use a 'hard handoff' as you travel between cell sites and commonly drop calls mid-conversation. CDMA uses a 'soft handoff', which connects you with the next cell site before you leave the one you're on.

Enhanced voice quality - CDMA translates your voice into digital transmissions, or tiny sound bites, at the highest translation rates possible. This makes your voice clear and maximizes the system capacity.
