通過光纜擴展BTS覆蓋範圍
帶有DBROU的BTS Link204 / 208雙頻光中繼器系統
BTS-Link 204/208中繼器是一種雙頻分佈式天線系統,用於點對多點的室內/室外覆蓋。它由安裝在靠近BTS的主光學單元(MOU)和安裝在遠距離(室內/室外)位置的遠程光學單元(ROU)組成。它使用單模光纖在MOU和ROU之間建立連接。 204版本最多支持4個ROU; 208版本最多支持8個ROU。
特徵
與GSM,CDMA,iDEN和WCDMA技術兼容
適用於700 MHz / SMR 800 MHz /蜂窩850 MHz / SMR 900 MHz / GSM 900 MHz / DCS 1800 MHz / PCS 1900 MHz / UMTS / AWS頻段兼容跳頻BTS低噪聲和高線性性能
MOU從DL路徑中的BTS接收預先分配的雙頻帶中的RF信號,並在轉換為單模光纖上的光信號後傳輸到不同位置的ROU
ROU將光信號轉換為RF信號並在放大後輻射
在UL路徑中,ROU接收來自移動用戶的RF信號,並將其轉換為光信號以傳輸到MOU,在MOU中,信號被重新轉換為RF信號以輸入到BTS
由於MOU和ROU之間的信號是作為光信號傳播的,因此天線隔離問題不重要。系統監視是通過具有簡單GUI的USB端口進行的
可以集成帶有RF調製解調器的遠程CMC監視(可選),可選的RMS(遠程管理系統)
微處理器控制的功能,例如本地控制,警報和RSSI指示,SNMP可選
應用領域
室內/室外覆蓋範圍取決於站點安裝的ROU
室內覆蓋的高層建築,醫院,購物中心等
隧道,高速公路和其他需要大面積覆蓋的室外場所
頻率帶寬
在任一預設服務頻段中均配備了單個子頻段,子頻段的帶寬可根據要求進行定制
Extend BTS coverage through optical cable
BTS Link204/208 Dual Frequency Optical Repeater System with DBROU.
The BTS-Link 204/208 repeater is a dual-frequency distributed antenna system for point-to-multipoint indoor/outdoor coverage. It consists of a main optical unit (MOU) installed near the BTS and a remote optical unit (ROU) installed at a long distance (indoor/outdoor) location. It uses single-mode fiber to establish a connection between the MOU and the ROU. The 204 version supports a maximum of 4 ROUs; the 208 version supports a maximum of 8 ROUs.
Features
Compatible with GSM, CDMA, iDEN and WCDMA technologies
Suitable for 700 MHz / SMR 800 MHz / Cellular 850 MHz / SMR 900 MHz / GSM 900 MHz / DCS 1800 MHz / PCS 1900 MHz / UMTS / AWS frequency band compatible frequency hopping BTS low noise and high linearity performance
The MOU receives the pre-allocated RF signal in the dual band from the BTS in the DL path, and transmits it to the ROU in a different location after being converted to an optical signal on a single-mode fiber
ROU converts optical signals into RF signals and radiates after amplification
In the UL path, the ROU receives the RF signal from the mobile user and converts it into an optical signal for transmission to the MOU. In the MOU, the signal is re-converted to an RF signal for input to the BTS
Since the signal between the MOU and the ROU is transmitted as an optical signal, the issue of antenna isolation is not important. System monitoring is performed through a USB port with a simple GUI
Can integrate remote CMC monitoring with RF modem (optional), optional RMS (remote management system)
Microprocessor control functions, such as local control, alarm and RSSI indication, SNMP optional.
Application field
Indoor/outdoor coverage depends on the ROU installed at the site
Indoor covered high-rise buildings, hospitals, shopping centers, etc.
Tunnels, highways and other outdoor places that require large area coverage
Frequency bandwidth
A single sub-band is equipped in any preset service frequency band, and the bandwidth of the sub-band can be customized according to requirements
