Kaval LNKFIB-R15 Cellular Fiber Repeater BDA 851-894 1931-1990 MHz RS-232 CAN

Kaval LNKFIB-R15 Cellular Fiber Repeater BDA 851-894 1931-1990 MHz RS-232 CAN

The Kaval Wireless Technologies LNKFIB-R15 is a fiber-optic bi-directional amplifier (BDA) and cellular repeater designed to extend and redistribute cellular and PCS signals across the 851–894 MHz cellular band and the 1931–1990 MHz PCS band. It handles simultaneous uplink and downlink signal paths for both Cell and PCS services via fiber-optic transport, making it suited for in-building wireless (IBW) and distributed antenna system (DAS) infrastructure deployments. Control and monitoring are provided through front-panel CAN bus and RS-232 interfaces.

Applications

Cellular fiber-optic BDA repeaters like the LNKFIB-R15 are used in distributed antenna systems (DAS) and in-building wireless (IBW) networks to extend carrier coverage into areas that cannot be reliably reached by a macrocell tower — such as large commercial buildings, tunnels, parking structures, stadiums, and campus environments. The fiber-optic transport architecture separates the donor (base station) signal from the coverage (antenna) signal, allowing low-loss signal distribution over long distances within a structure. The LNKFIB-R15 covers the 800 MHz cellular band (used by carriers like AT&T and Verizon on legacy CDMA and early LTE services) and the 1900 MHz PCS band (used for CDMA, GSM, and early LTE deployments in North America). Units of this type were widely deployed in the 2000s and early 2010s as carriers built out indoor coverage networks; they continue to see use in legacy DAS infrastructure maintenance and upgrade projects. The CAN bus interface supports network-level monitoring and control typical of managed DAS head-end and remote unit architectures.
