Professional bts base station manufacturer for stairwells

PRODUCT SPECIFICATIONS

ZXSDR R8882 is one distributed Remote Radio Unit (RRU) used in Uni-RAN total solution, with two transmitters. The RRU is based on the common new generation RRU platform, and can work in GSM and UMTS single mode or multi-mode in the same frequency band.

Benefits:

Software Defined Radio (SDR) is the evolution of base station technology. ZXSDR series has made great effort and invested much in this new technology for many years. And then the R8882 RRU product and B8200 BBU product based on SDR technology were released.

SDR Uni-RAN architecture supports GSM, UMTS, LTE and Uni-RAN simultaneously. Operators then can benefit a lot from SDR platform. The following part lists the key benefits for operators.

lHigh performance

To meet the growing demands for wide working bandwidth, R8882 modules with full working bandwidth are released. Maximum working bandwidth of R8882 is 75MHz for 1800M band and 35MHz for 900M band. For frequency spectrums become scarce, resources allocated for operators tend to be characterized with fragmentation and large span. RRUs with full working bandwidth integrate more spectrum resources and help to decrease hardware investment exponentially.

lClearer and simpler network

R8882 supports GSM, UMTS, LTE or mixed technologies. Instead of running hardware on independent platforms for each technology, operators can implement various wireless technologies in software on the same hardware platform.

Since hardware platforms can be reused, there is significantly less investment risk for deploying hardware. Wireless technologies are developing so fast, and investing on one technology may bring risks to operators. SDR-based solutions will decrease the investment risk since SDR platform can support various technologies.

lLower Total Cost of Ownership(TCO)

ZXSDR R8882’s PA adopts advanced efficiency enhancement technologies to realize high power efficiency, such as Doherty PA, DPD linear technology and MCPA technology. Power consumption can be greatly decreased together with these features. Passive thermal dissipation design also contributes to power saving and less noisy. The operation and maintenance of one single wireless network is much simpler than multiple system networks. Fewer engineers are required and less implementation to be taken for system interworking or upgrade.

Physical Structure:

R8882 is the multi-carrier RF module with two transmitters. It has two PAs, with both PAs working on 850M/900M/1800M/1900M/2100MHz/AWS. There are two types of R8882, 2T2R and 2T4R. The differences between 2T2R and 2T4R modules include working bandwidth and number of receivers. In the physical appearance, R8882 2T4R has four antenna feeder interfaces but R8882 2T2R only has two. Except this, there is no difference in the shell.
