3 Technological Characteristics
Traditional digital microwave equipment generally transmits E1 signal only, so there is always the need to
apply for frequency channel use because of technological limitations.
In recent years, there is a dramatic change in the structure, composition and application of digital microwave
communicative equipment. The traditional system of transmission has been changed to the integration of
transmitter and receiver as well as from fixed frequency to the possibility of frequency conversion from low to
high frequency band. In view of the high frequency digital microwave communication system’s new changes
and additional newer characteristics, we had already improved the traditional system to a great length
E1 Spread Spectrum Radios has the following technological characteristics:
-- High frequency band: 2.4、5.8GHz
-- Complete capacity: 2*E1、4*E1s、8*E1、16*E1
-- Simplified set up: The ODU’s Signal Indicator indicates the correct angle adjustment of the antenna
-- Flexible interface: suitable for multiple network and service links
-- IDU and ODU unit connected by a single IF cable up to 200m length, thereby, decreasing the RF
transmission loss and increasing the receiving signal-to-noise ratio (S/N)
-- Channel conversion function reduce the cost of large and flexible network deployment
-- Digitally advanced QPSK de/modulation
-- Powerful monitoring function: simple and easy to operate LCD display. With the overall status display and
loopback test function, users can easily maintain the system without the need of special equipment to
ascertain any malfunction
-- Improved network management system suit a lot of different network topological structure. It can manage up
to 255 station equipments and also extend the monitoring support to other microwave equipments
-- Quick and easy installation
