Chapter 1
System Architecture
This chapter describes the background, the standards followed, major
functions, system features, working principles and the general structure of
both the software and hardware of the ZXG10-BTS (V2.9).
System Description
System Background
The ZXG10-BTS (V2.9), an indoor type macro cell BTS, is ZTE’s second
generation BTS product.
Apart from the advantages from the ZXG10-BTS (V1A), the ZXG10-BTS
(V2.9) features large capability (single cabinet holding twelve 40WTRXs),
compactness (the size similar to overseas 6-carrier unit), high reliability,
high cost performance ratio, comprehensive functions, and powerful
service support capability (supporting GPRS/EDGE data service function
and ARM adaptive multi rate voice service).
Note: AMR, which is the voice coding scheme of 3GPP, has eight rate modes
including 4.75, 5.15, 5.90, 6.70, 7.40, 7.95, 10.20 and 12.20. They can
adaptively change coding rates from terminals and networks respectively according
to different channel quality reports, which reduce influences caused by fading error
of channels, data congestion and delay, improve voice quallities to the maximum
extent. In order to implement smooth transition from GSM to 3G, the GSM
network need provide AMR-support to realize switching the roaming of mobile
phones between 2G and 3G network.
The ZXG10-BTS (V2.9) is not only applied to the large and medium-sized
cities with heavy traffic and the districts with heavy traffic in medium and
small-sized cities, like busy business districts and airports, but also to the
districts with little traffic in medium and small cities and rural areas. In
addition, proper network planning can make it applicable to different zones
like mountains, hills and expressways.
Development of the ZXG10 BTS(V2.9) enriches ZTE’s series of BTS
products and enables the system with more flexible networking modes,
thus producing stronger market competitiveness.
