16. It supports preprocessing of the measurement reports on the OB06. 
17. It supports BS power control: statically 6 levels and dynamically 15 
levels. 
18. It supports all paging modes defined in GSM specifications. 
19. It supports synchronous handover, asynchronous handover, pseudo-
synchronous handover, and pre-synchronous handover. 
20. It has an overall timely alarm system. 
i.  Available for implementing unattended BS and automatic alarming. 
ii.  Providing power supply and alarm for the built-in tower amplifier 
system. 
21. It supports EDGE service, realizing a higher data transmission rate by 
means of 8PSK modulation. 
22. It supports GPRS and CS1 ~ CS2 channel encoding modes. It supports 
CS3 and CS4 through software upgrading, and it can adjust the 
channel encoding mode dynamically according to the monitoring and 
measurement results. 
23. The Um interface supports A51/A52 encryption algorithm. 
24. It supports ultra-distance coverage with a radius of 35 km~120 km.
