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.

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.

Engineers need precise methods of characterizing components due to greater design complexities caused by modulation schemes such as PSK and QAM (used in WCDMA and EV-DO) and OFDM (used in WiMAX and LTE), as well as higher power-efficiency requirements and improved linearity. Modern devices and components must also introduce less distortion and be developed at lower costs. These factors make design and test a bigger challenge than ever before.

Time Division Synchronous Code Division Multiple Access (TD-SCDMA) is an air interface found in UMTS mobile telecommunications networks in China. It is a Time Division Duplex (TDD) 3G technology as opposed to Frequency Division Duplex (FDD) like W-CDMA. TD-SCDMA is primarily used for voice and it utilizes a TDD version of HSPA for data. China Mobile is the operator in China utilizing this technology making it the largest 3G network operator in the world.

For over 110 years Anritsu has been a leader in developing emerging technologies. First to provide 3G test and measurement solutions to the wireless market, we are now firmly established as the leader of 3G test. First to develop a range of products for HSPA, Anritsu is now at the forefront of developing solutions that meet not only the broader need of this technology, but also the industry's demands for implementing LTE and Next Generation Networks.

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.

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.

You expect the technology to work smoothly and seamlessly "out of the box". This is where Anritsu can help. Anritsu understands that the success of a technology, and any products integrating that technology, is dependent on users enjoying excellent high quality connections the first time it is used.

Reading email and surfing the internet while on the move, at an airport or in a café, has become an accepted part of daily life. Now WLAN technology is also being integrated into mobile phones and PDAs so that users of these products can also benefit from improved access to data while on the move.
