1 Introduction to the MA 2000 System MobileAccess 2000 provides a cost effective solution that enables multi-operator indoor coverage of voice and data wireless services through a single coax antenna infrastructure. MA 2000 provides scalable indoor coverage for enterprises, where support for coverage from additional operators in any band range, for example CELLULAR 800MHz band and GSM 900MHz band, may be added as needed, without changing the infrastructure.
PAGE 14
Introduction to the MA 2000 System System Architecture Features and Capabilities 1.1 • Support for all current and future technologies such as TDMA, CDMA, WCDMA and GSM, and services such as PCS/CELLULAR, Paging, iDEN and 802.
PAGE 15
Introduction to the MA 2000 System System Architecture • 1.1.3 MA 1200 Add-on – supports a single voice service. It enables a host RU to which it is connected to provide an additional service. • MA 850 – flexible and maintainable wireless transport platform that enables large-scale WiFi deployments and distribution of data services from 802.11a/b/g APs through the same antennas as the voice services.
PAGE 16
Introduction to the MA 2000 System System Architecture 1.1.4 System Operation Figure 1-2 shows a basic block diagram of the system operation. On the downlink, the services from the BTS/BDA are transferred via interface to the Base Units. The interface, which may be passive (i.e. Interface Box) or active (RIU), is used to attenuate the RF signals to the required levels, converge them and distribute them to the BUs. The BUs are wideband – they are not service specific.
PAGE 17
Introduction to the MA 2000 System Application Example 1.2 Application Example Figure 1-3 shows an example of an MA 2000 Cabinet based solution. Five services from two different operators are distributed, where services from Operator A conflict with those from Operator B. The converted optical signal is routed from the BUs directly to the corresponding RUs in each Cabinet over optic fiber. Each BU supports connections to 8 RUs. Additional BUs are required for connection to more RUs.

7 Appendix I: Optical test Procedures 7.1 General Two parameters are of prime importance when testing optical cables or jumpers for use with Mobile Access products: • Optical Loss – the difference between the optical power at the input and output of an optical cable. It must be measured (usually in dB units) at 1310 nm. The maximum allowable loss should be < 0.5 dB/km for Single Mode (SM) cables and < 0.5 dB for every mated pair of connectors.
