Page 11: Typical In-Building Coverage
Indoor coverage varies greatly due to the nature of various building construction techniques materials. Approximations signal level/coverage can be determined with the following assumptions: • 10dBi to12dBi-donor antenna. Max. 9dBi indoor omni/directional antenna. Page All Rights Reserved Shyam Telecom Limited 11/43... - Page 12 • Isolation between the donor and server antennas should be 15 dB more than the gain of the repeater.

There are two types of users viz. ADMINISTRATOR and SUPERVISOR. If user logged in as an ADMINISTRATOR, all the operation through the CMC can be carried out. The password by default is “SHYAM”. SUPERVISOR is allowed to perform monitoring of the status & alarms but no change in configuration is permitted. - Page 15 Figure 4: Log-in Repeater II) Configuration Configuration means setting different repeater parameters for proper operation. Configuration of Shyam repeaters can be performed locally with a laptop / PC connected to the repeater by means of local USB serial interface cable.
