The base station is at the core of your RF wireless installation. It’s where you make the connections for your cables, antennas, transmitters and receivers. And it’s where most problems can occur that can affect performance through component failures, wireless interference or incorrect installation or maintenance. The result can be unacceptable downtime for your networks, and time-consuming work to fix the problem by your field techs.
Anritsu's Base Station Central is here to help. We've gathered a variety of technical resources to help you track problems, educate your people, look up terminology and much more. You’ll also find product specs for a full line of base station testers, cable and antenna analyzers, spectrum analyzers and accessories. As the leader in the field, Anritsu makes the largest variety of high quality base station analyzers and peripheral equipment designed for reliable operation that saves you time and money.
However, you don’t have to use our products to benefit from the materials on this site since many of the measurements are universal. So please bookmark this site and come back often whenever you need specs for test and analysis equipment for GSM, W-CDMA, HSPDA, CDMA, EV-DO, WiMAX and TD-SCDMA as well as such applications as line sweeping, DTF (Distance-To-Fault) measurements and vector signal analysis.

TDD/FDD Access
LTE standards support the use of both TDD (Time Domain Duplex) and FDD (Frequency Domain Duplex) from the same set of standards, and with the same air interface characteristics.
Multiple Input Multiple Out (MIMO) MIMO is an antenna technology that, together with signal processing, can either increase capacity (spatial multiplexing) or signal-to-noise ratio (transmit diversity) in a radio link.
In LTE using 2x2 MIMO with spatial multiplexing, the user data is separated into two data sets each fed to two transmit antennas and received by two receive antennas. Because of multi-path, each data set travels a distinct RF path with different propagation characteristics. The algorithm used to split and recombine the data allows the system to make use of the independence of these two paths in order to improve throughput. The two data streams occupy the same RF channel at the same time. This doubles the data rate possible on the air interface link.
When using MIMO with transmit diversity, the same user data is transmitted from both antennas, and at each receiver, replicas of the signal are processed. This duplication enhances signal-to-noise ratio and improves signal robustness.

Wireless communication systems are becoming increasingly complicated. They are shifting to higher frequencies and wider bandwidths to support high-speed communications, with the IEEE 802.16 WiMAX Standard an excellent example.
When developing WiMAX equipment, engineers must be sure it performs in the higher frequencies of the WiMAX spectrum. At the manufacturing stage, equipment must be tested efficiently. Once delivered and deployed, WiMAX sending and receiving equipment is subject to the usual challenges of antenna and transmission device tuning and radio interference.
All of these scenarios call for a new generation of test tools with excellent accuracy and wideband analysis at the higher frequencies utilized by WiMAX. In addition, equipment must be flexible to support WiMAX profiles which may vary from region to region and are frequently revised.
Anritsu's role in WiMAX
Anritsu is a leading manufacturer of instruments used in R&D, product testing, manufacturing, network and user equipment testing, and field maintenance of wireless communications technology. Anritsu has made a strong commitment to WiMAX with the goal of offering solutions that will help manufacturers and carriers keep up with evolving standards and get products to market faster.
Anritsu is an active member of the WiMAX Forum and its products have been exhibited at the TWG (Technical Working Group) and the WiMAX Forum's Plugfests. Two products, the MG3700A Vector Signal Generator and the MS2781B Signature Vector Signal Analyzer are listed in the State of the Art (SOA) Equipment document of the WiMAX Forum.
This area is designed as a one-stop reference for engineers involved in WiMAX testing and measurement including the selection of test equipment and software suites, the setup of base stations and antennas, and ongoing maintenance of Mobile and Fixed WiMAX communications systems. Here you'll find the latest news, educational documents and web seminars, as well as information on the latest products from Anritsu. BOOKMARK this page and please come back often!
