Baseband Unit (BBU) is responsible for processing the baseband signals. ZTE provides three types of BBUs:
ZXSDR B8200/B8300 can be used in the integrated indoor/outdoor base station, or connected to RRUs/AAUs in the distributed base station. Based on ZTE unique SDR platform, it supports GSM/UMTS/FDD-LTE/TDD-LTE (GUFT+N) multi-mode configuration and smooth evolution. It enables operators to deploy one unified radio access network rather than independent GSM, UMTS or LTE networks, which brings simplicity and convenience with low CAPEX and OPEX.
GUFT+N multi-mode multi-band, large capacity, and smooth evolution
Higher data rate with TDD-LTE and FDD-LTE carrier aggregation (CA)
Easy expansion with GUF multi-mode base band processing board
Fast installation with small volume
Flexible networking with all-IP structure
Pad BBU is a compact BBU, which features a small volume, low power consumption, high density and zero noise. It can be used for both indoor and outdoor application scenarios with natural heat dissipation and IP65 protection. The unit can be mounted on the wall or on the pole, no need of extra cabinets. And it can be flexibly installed near the RRU to save the optical fiber resources.
GUF multi-mode large capacity
Small volume and fast deployment
Compact design and green BBU
Patent waterproof solution and tough environments adaptability
Cascaded connection and flexible networking
Distributed base station adopts the structure of separated baseband unit (BBU) and remote radio unit (RRU), which not only facilitates flexible deployment and decreases the construction cost, but also saves feeder loss and enhances network coverage. It is widely accepted by operators around the world. Therefore, RRUs with different features are customized for all kinds of scenarios such as high output power, ultra broadband, high integration, multi-PA etc.
High Output Power Ultra Broadband RRU (UBR): As the first UBR product in the industry, each RF channel of the ZTE UBR product supports an ultra broadband spanning across dual bands. One UBR supports multi-band and multi-mode networks. The network which previously required at least two RRUs per sector can now be replaced by one UBR product per sector. RRUs and feeders are cut by 50%.
Large Capacity High Maturity 8T8R RRU: As the first ultra broadband 8T8R RRU product in the industry, it provides large capacity and long-distance coverage with transmission power of 8*20W, as well as the ability to support 4 carriers. Being commercially mature, its good performance has also been validated in existing network. Its total shipment ranks first in China Mobile’s 8T8R RRUs.
Ultra Broadband High Power 4T4R RRU: As the first ultra broadband high power 4T4R RRU product in the industry, it has four key highlights as follows:
Ultra broadband: Supports up to 160MHz IBW. One RRU can cover the whole bandwidth.
High power: Power of single channel reaches 40W, greatly reducing the CAPEX.
Multi-carrier: Supports multi-mode/frequency network, four carriers and multi-carrier aggregation.
Flexible split: Supports a RRU being split into two 2T2R units, convenient and flexible deployment.
Cost-Effective 3T6R RRU: One 3T6R RRU supports GU dual-mode in 3 sectors. Dual-RRU combination supports LTE 2x2MIMO in 3 sectors, decreasing the evolution cost and protecting the existing investment. Compared to the traditional solution, the number of RRUs drops and the load requirement is lowered down, which enables fast installation and saves roof resources. In addition, 3T6R RRU adopts natural heat dissipation, eliminating the noise trouble.
High Power Wide Coverage 2T2R RRU: The 2T2R RRU has the highest transmission power among 2T2R products in the industry and supports 2x2 MIMO multi-carrier aggregation, effectively enhancing network capacity and coverage. Its compact design and diversified installation methods facilitates the fast deployment in different scenarios.
High integration iMacro (AAU): An active antenna unit (AAU) is the integration of the traditional RRU and the antenna. The integrated architecture of the AAU achieves less feeder loss, which enhances the coverage. ZTE AAU product uses the ultra broadband technology to meet the multi-band and multi-mode network construction requirements. It requires less space and is easy to be hidden from sight, which makes site acquisition and rapid deployment easier.
ZTE Macro Base Station (BS) series include three types: large capacity indoor base station ZXSDR BS8800, modularized outdoor base station ZXSDR BS8900A, and large capacity outdoor base station ZXSDR BS8900B. Based on the distributed architecture, the baseband unit B8200 and a variety of indoor RF units RSUs are combined and assembled in the base station cabinet. Among them, the outdoor BSs can also provide transmission, lightning protection, power supply and batteries, and reserved room for other devices, supporting fully functional outdoor BS solutions.
The products support ZTE unique 2T4R RF module, with a single module supporting 2 sectors or 2T4R, reducing cost and improving the performance of network; support power amplifier with high efficiency, contributing to very low power consumption; support GSM/ UMTS/LTE (GUL) multi-band multi-mode, saving CAPEX and OPEX significantly.
Large Capacity Indoor Macro BS ZXSDR BS8800 Highlights
Large Capacity: One BS8800 accommodates 2 BBUs and 12 RSUs, and connects with Remote Radio Unit (RRU) to support more cells.
Mature Application: Already being commercially applied in more than 100 countries. The excellent performance is guaranteed.
Modularized Outdoor Macro BS ZXSDR BS8900A Highlights
Modularized Design: Supports centralized or distributed cabinet installation according to the practical conditions.
Cost Effective: BS8900A contains baseband units, RF units, lightning protection, power supply and battery, and reserved room for transmission device, providing cost-effective and fully functional outdoor site solution.
Large Capacity Outdoor Macro BS – ZXSDR BS8900B Highlights
All-in-One Solution: Single rack of BS8900B contains baseband units, radio modules, lightning protection, power supply and battery, and reserved room for transmission device, providing large capacity and fully functional outdoor site solution..
Large Capacity: Single rack accommodates 2 BBUs and 9 2T4R RSUs, and connects with Remote Radio Unit (RRU) to support more cells.
During the 2016 Mobile World Congress in Barcelona, ZTE officially released a new generation of miniaturized Magic RRU products following the success of previous Magic RRUs in global business. The new generation RRUs, adapting to a variety of scenarios, set a new record in raising the power amplifier efficiency. With the minimum volume and weight in the industry, the new generation products can help operators quickly and flexibly construct a low-cost, high-performance and converged 2G/3G/4G mobile communication network.
Smallest and Lightest 2T RRU: The 2T RRU of the Magic RRU family, smallest and lightest in industry, with only 2/3 of the volume of previous generation products, is easy for site acquisition and fast for installation.
High Output Power Full Working Bandwidth (FWB) RRU: 2*80W high output power supports multi-mode large capacity. Full working bandwidth can help operators with dispersed spectrum save half of the RF modules and feeders. Four receiving ways can enhance significantly the uplink coverage and performance, reduce effectively the mobile transmit power and extend mobile standby time.
High Performance 4T4R RRU: One single RRU can support 4x4 multiple input multiple output (MIMO) technology, with nearly 50% reduction in the volume, contributing to quick and easy installation. Compared to 2x2 MIMO, the data rate per carrier doubles. Combined with multi-carriers aggregation (CA), a single user’s peak data rate exceeds 1Gbps.
Compared with the traditional macro station, the Small Cell BS features much smaller volume, transmitting power and coverage. The statistics show that the vast majority of data services occur in indoor or hot spots. Small Cell base stations (BS) effectively enhance the deep coverage, increase the network capacity, and improve the user experience, attracting more and more attention from the industry.
ZTE Small Cell series of BSs include integrated outdoor Micro station, outdoor Pad RRU, indoor Pico station, indoor Femto station and indoor Qcell series products.
