The hub connects directly to the coaxial portion of cable plant using a standard power
extracting tap and is line powered over coax using 60 or 90 VAC. The CPE is installed at
the customer site, connects to a standard cable modem, and is powered over the coax
cable using a wall mounted AC adaptor and DC to coax power inserter.
In the downstream direction the hub receives a digitally modulated EIA standard or
Harmonically Related Carrier (HRC) Offset cable channels in the range between 88 and
860 MHz from the cable plant and up converts it to one of the six available wireless
channels in the upper part of the 5.8 GHz frequency band. The CPE receives the wireless
signal and down converts it to a channel in the range 93 to 123 MHz for reception by a
cable modem.
In the upstream direction the CPE transmits the entire 10 to 42 MHZ frequency range in
the lower part of the 5.8 GHz frequency band. The hub receives the wireless channel,
tunes to the frequency carrying the active upstream channel, and down converts it back to
the original frequency in the 10 to 42 MHz range. With Arcwave’s PureBurst upstream
noise suppression technology the hub’s upstream transmitter is only “opened” when a
wirelessly attached cable modem is sending data. The digital signals are never
demodulated/modulated ensuring transparent service and equipment support.
Coverage and Range
The ARCXtend Enhanced 5.8 GHz WPE solution hubs are factory configured for
extended range or extended coverage applications. The range and coverage profile for
both solutions are detailed in the following table and illustration.
