As a distributed antenna system, it provides analog and digital phone systems that are served in multiple bands through one antenna. The system covers general public institutions and private facilities. Shopping malls Hotels Campus areas Airports Clinics Subways Multi-use stadiums, convention centers, etc. The system helps improve in-building radio environments in poor condition and make better poor RSSI and Ec/Io. By providing communication services at every corner of buildings, the system enables users to make a call at any site of buildings. The system uses both analog (AMPS) and digital (TDMA, CDMA and WCDMA) methods. The Alliance 2W system supports communication standards and public interface protocols in worldwide use. Frequencies: VHF,UHF, 700MHz, 800MHz,850MHz 900MHz,1900MHz,2100MHz, etc. Voice protocols: AMPS,TDMA, CDMA,GSM,IDEN, etc. Data protocols: EDGE,GPRS,WCDMA,CDMA2000,Paging, etc. Alliance 2W is in modular structure per frequency. To provide desired frequency in a building, all you need to do is to insert a corresponding frequency module into each unit. As it delivers multiple signals with one optical cable, the system, in one-body type, does not require additional facilities whenever new frequency is added. The system is featured with the following:
Flexibiltiy & Scalabiltiy Support fiber-optic ports up to 39 Clustering multiple-buildings (campus) as one coverage Modular structures Modular frequency upgrade Plug-in type module Multi-Band, Multi Operator Confidential & Proprietary 10/23 Signals with a plurality of service provider transmit simultaneously Support multi-operator in a band Low OPEX / CAPEX Compact design Upgradable design Easy installation and maintenance Web Based SNMP or GSM Modem or UDP support (Optional) 2.2 Alliance 2W L2ROU receives TX optical signals from ODU or OEU and converts them into RF signals. The converted RF signals are amplified through High Power Amp in a corresponding L2RDU, combined with Multiplexer module and then radiated to the antenna port. When receiving RX signals through the antenna port, this unit filters out-of-band signals in a corresponding L2RDU and sends the results to Remote Optic Module to make electronic-optical conversion of them. After converted, the signals are sent to a upper device of ODU or OEU. L2ROU can be equipped with up to three L2RDUs (Remote Drive Unit) and the module is composed of maximal Dual Band.
