Personal Handy-Phone System

“Providing wireless local loop connectivity”

Personal Handyphone System, known as PHS, has been in existence in Japan for years. In the mid-1990s, UTStarcom introduced its IP-based Personal Access System, iPAS, based on the PHS standards and specification. The iPAS network is a low-cost and easy to deploy wireless alternative to copper offering the flexibility of fixed, portable and mobile voice and data services concurrently. Today UTStarcom’s iPAS networks support more than 55 million subscribers globally. These subscribers receive Class 5 NGN IP service enabled by UTStarcom’s mSwitch™ NGN core network.

Operating in the 1880-1920MHz spectrum, UTStarcom’s iPAS solution is the preferred cost-effective alternative for operators with a shortage of circuit capacity. Operators can migrate their current wireline network to an Internet iPAS network that provides wireless voice and data services within a city or community. The system enables service providers to offer new wireless services, such as citywide mobility, same-number wireless extension, email, mobile Internet access, short messaging, and location-based services. iPAS interconnects with the existing Public Switched Telephone Network (PSTN) by way of the Signaling System 7 (SS7) interface, making it an ideal solution for areas where either extra switching capacity or the V5.2 Next Generation Integrated Digital Loop Carrier (NG-IDLC) interface is not available.

The iPAS system, which ensures rapid wireless deployment, is ideal for large installations via its linear scalability and support for 10,000 to 5,000,000 subscribers on a single installation. Service providers deploying an iPAS network can rapidly build a wireless access network, bypassing the time-consuming process of copper infrastructure installation, Radio Frequency (RF) planning, and new mobile switch and backend system deployment. Voice services can be delivered more cost-effectively than traditional cellular phone service or fixed line service, which is imperative in a Wireless Local Loop deployment.
