Integrative Outdoor Macro-BTS

Overview

The full name of CBTS O1 is Compact Base Transceiver Station (Outdoor type 1). As the new-generation CDMA compact and outdoor macro-BTS rolled out by ZTE, ZXC10 CBTS O1 is attached with transmission equipment, temperature control device and power supply system that are protected from rain, snow and dust,  guarded against theft and applicable for miserable and severe outdoor conditions.

Using an All-IP structure, ZTE's new-generation CBTS can fully satisfy user demands for multiple services.

Features 

 High Integration

The completely integrated product design meets various requirements of the outdoor BTS.

Excellent Outdoor Environment Adaptability

  • The CBTS O1 is an outdoor BS using sealed cabinet well protected from water, dust, burglary, rodent nuisance, and electromagnetic shielding.
  • The CBTS O1 is compliable with IP55 protection standards.
  • The CBTS O1 provides class-(B+C) lighting protection.
  • The CBTS O1 equipment can work normally when the ambient temperature is between -40ºC (-40ºF) and +55ºC (+131ºF). It is designed with heat exchanger technology to meet the requirements for forced cooling, thus improving the reliability of components. It uses an internal heater to make sure that non-industrial components can work normally at low temperature.

 Small Size

The ZXC10 CBTS uses a compact structure. The ZXC10 CBTS only needs a small space, thus greatly saving the equipment room space.

 Large Capacity

  A single CBTS cabinet supports up to 12 carrier-sectors (4C3S). And it supports cabinet combination. In a 1x network, a single BDS shelf can support 24 carrier-sectors; In a DO network, a single BDS shelf can support 12 carrier-sectors.

Providing both 1X and DO on a Single Cabinet

Broadband RF

The CBTS RF board supports a broad frequency band. Four carriers within 10M bandwidth can be flexibly configured.

Advanced ARIR Function

It supports the advanced ARIR (Adaptive Reverse Interference Resistance) function against reverse narrowband interference and adapts to complicated wireless environments.ZTE's ARIR function supports multi-carrier reverse interference resistance.

  High Reliability

  GPS adopts dual-ovenized crystal to ensure short-term stability of the clock. The HOLDOVER algorithm is adopted to enable 72-hour locked mode after the GPS signals are lost, so that the normal operation of the BTS can be guaranteed.

Smooth Capacity Expansion and Update

Flexible Networking Modes

When both the BTS and the BSC are installed in the same equipment room or they are placed near each other, it is recommended to connect them directly. In this case, a complicated Abis link compression protocol is not required. Thus the cost is reduced and the reliability is improved.
