Subsystem
Internet Subscriber Unit
The INTERWAVE '99 Internet subscriber unit (ISU) is a low cost wall- or pole-mounted transceiver (with or without the antenna) that is compatible with standard DOCSIS cable modems. Designed to operate in any 200 MHz segment of the 2100 to 2700 MHz MMDS band, the ISU architecture is implemented to minimize the spectral regrowth, adjacent-channel power and error vector magnitude critical to QPSK, QAM and DQPSK modulation used with CDMA and other wireless voice and data network architectures. Operating temperature range is -40° to +65°C. Size: 8.0" x 10.0" x 1.6".
