ZXG10-OB06 (V1.0) Integrated Outdoor GSM Base Station Technical Manual
• Support synchronous, asynchronous, pseudo- synchronous and pre-
synchronous handovers.
• Provide functions as protection and electromagnetic filtration. The
power system features the following:
•
•
•
•
•
•
• Power system contains external high-capacity batteries. It provides a
function for management of secondary power down and batteries.
• Uses standard RS232 interface for connection with the local operation
and maintenance terminal. It also provides rapid and reliable online
software upgrade.
• Possess prompt alarm system for the following:
•
•
•
• Support EDGE service hence has a higher data transmission rate by
means of 8PSK modulation.
• Support A51/A52 encryption algorithm at Um interface.
• Support ultra-distance coverage with a radius of 35 km ~ 120 km.
