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.

A timely opportunity for America
Through the American Recovery and Reinvestment Act of 2009, $7.2 billion was made available to expand broadband access to unserved and underserved communities across the United States. The initiative is coordinated by the Department of Agriculture’s Rural Utilities Service (RUS) and The Department of Commerce’s National Telecommunications Information Administration (NTIA).

Anritsu is proud to contribute to Broadband Stimulus with test and measurement instruments that make it easier and faster to deliver the promise of universal high-speed connectivity. Our equipment has been proven at most major carriers and communications industry suppliers in demanding field applications around the globe.

We hope you will bookmark this section of our website and come back regularly. You’ll find constantly updated news and articles of interest, basic reference material on Broadband Stimulus, and links to appropriate Anritsu product information.

Assessing a signal environment to ensure proper deployment, installation and operation of wireless networks is no easy task. From natural obstructions such as mountains to man-made obstacles like wind turbine generators, signal integrity is one of the biggest concerns for wireless service providers, public safety users, LMR operations and government officials.

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.

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.

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.
