certification programs, and its industry trade show, the Personal Communications ShowcasePCIA is committed to maintaining its position as the association for the PCS industry.
PCIA's member companies include PCS licensees and those involved in the cellular, paging, ESMR, SMR, mobile data, cable, computer, manufacturing, and local and interexchange sectors of the industry, as well as private corporate systems users, wireless system integrators, communication site owners, distributors and service professionals, and technicians.
Personal communication service includes a broad range of telecommunications services that enable people and devices to communicate independent of location. PCS networks and devices operate over a wide range of frequencies assigned and authorized by the FCC. There are currently seven different air interface technologies proposed for standardization for the new PCS licensees that will be operating in the 1.8 GHz band. Service providers that will be operating at these frequencies either are new entrants with no established network or are existing telecommunications service providers, such as cable, cellular, local exchange, and long-distance carriers. With the technology choices companies make over the next few months, there will need to be analysis of how and to what extent the various wireless and wireline networks will work together.
To facilitate roaming among PCS carriers, some degree of interoperability and interworking needs to be accomplished between the networks. PCIA defines interoperability and interworking as follows:
Standards should be developed and are currently being worked on in domestic and international standards bodies to facilitate features and services delivered consistently and in similar fashions to an end user, regardless of the air interface and/or network implementation used. All networks do not necessarily need to interoperate or interwork with every other network; those decisions will be made on a company-by-company basis. But the industry is working to make sure that if that choice is made, the technology will be available to support it.
