ADC Telecommunications Inc. will demonstrate its Homeworx hybrid fiber/coax system at SuperComm ’97 this week in New Orleans. The demonstration will show the two-way capability of multichannel multipoint distribution service for delivering voice, video and data services to a large service area, said the company. The demonstration incorporates MMDS transmitters and receivers at a central office or headend. Signals are transmitted over the air in the 2.5 GHz frequency range to “line of sight” receive antennas located at customer locations. Potential customers include small office/home office businesses, schools and residential subscribers in apartment buildings and homes.
The company also will debut its line of ancillary equipment for wireless communications cell sites including its SmarTop 1800 and 1900 dual duplex and its SmarTop 800 and 900 RX tower top amplifiers. The products feature functions such as monitoring antenna and cable by an integrated voltage standing wave radio sensor unit, remote control and alarm functions by dual-tone multifrequency signaling, bypass switch, balanced parallel single stage low noise amplifier and high mean time before failure.
