EXHIBIT B pes Technology & Information: Background In early 1995, the Federal Communications Commission (FCC) auctioned licenses for the range of 1,850 to 1,990 MHz band of the radio spectrum for 51 Major Trading Areas (MTAs) of the United States for use as Personal Communications Services. SSLP purchased licenses for 29 of these 51 MTAs. These licenses, in combination with the licenses awarded to its affiliates and other providers, will enable SSLP to offer seamless Personal Communications Services virtually anywhere in the country. What is PCS? PCS is a new wireless telecommunications service that is personalized to the individual. PCS technology will allow a variety of telecommunication services. including: . Local and long distance telephone services; .. Cable services; . Portable telephones and facsimile transmission capability; . Paging: . Numeric paging using the portable telephone screen; . Interactive paging (2-way paging which allows the sender to track where the message is sent, and when it has been received.); . Voice mail service; . Caller 10; . International roaming capability; and . In the future, computer use and video images will be available through the PCS network. The types and features of services that each subscriber desires will be customized to his or her unique needs. Telephone numbers used in PCS handsets will be assigned specifically to an individual user, a Personal Communications Number (PCN). The main advantage of a PCN is access to a variety of features and services with a single telephone number. A PCN will also allow the network to track the individual at all times. Benefits of pes over Cellular PCS has several advantages over existing cellular telephone service, including improved service quality through the use of digital technology, enhanced service features, increased mobility, more compact radio equipment, and lowered price. Digital Technology PCS utilizes the latest digital technology. This will facilitate improved call clarity, but more importantly, clean data communication. A PCS customer will be able to communicate ~hrough voice and data simultaneously using the same handset without interference to either activity. In addition, computer users will be able to run applications and retrieve data faster from remote locations using their handset. PCS technology also assures less static and fading than current cellular technology and results in fewer dropped calls. Improved Security Digital technology provides more security than. analog, the technology traditionally used by the cellular industry. Calls in digital format cannot be overheard with the simple scanners currently used to eavesdrop on cellular calls. Eavesdropping on PCS transmissions is technically possible yet requires special equipment and technical skill which most- eavesdroppers lack. 114V2.doc
