General Wireless Communications Service (GWCS) operates in the 4.6 GHz frequency spectrum (FCC Part 26). While WCS and GWCS do not include enough frequency spectrum alone to be considered a broadband service, many WCS and GWCS licensees combine their operations with other services (i.e. MDS and MMDS) to provide two-way broadband services to a market. Because the design of these systems can be rather complex, DC uses sophisticated software tools to meet a client's needs in the development of these systems. UNLICENSED SERVICES By unlicensed services, we refer to those transmitting devices that must meet certain defined equipment tolerances, but that are otherwise unrestricted in their deployment.  Actual systems that employ such equipment are considered unlicensed because prior FCC authorization and FCC licensing requirements of these systems are unnecessary. Part 15 of the FCC Rules establishes equipment tolerances for transmitting devices that are considered unlicensed.  FCC Part 18 covers frequency bands of certain industrial, scientific and medical (ISM) equipment that can also be used in an unlicensed manner.  Certain of the ISM frequency bands (including 2.4 and 5.8 GHz) are available for use by commercial entities. Such unlicensed facilities have extremely low power and small coverage footprints.  Also, because these systems are unlicensed, they are not protected from interference.  Such interference can become extreme in areas where multiple unlicensed systems that use the same frequency spectrum are installed. Many systems are currently being developed that employ both licensed and unlicensed services (known as hybrid systems).    Click (Here) for an easy to print downloadable PDF brochure of all our services.
