Coverage and Interference Mapping

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.

CPRI and OBSAI

Mobile traffic volumes are growing rapidly due to the spread of OTT video services (YouTube, Mobile IPTV, etc.). Consequently, so-called small-cell networks are being deployed to create a better communications environment by expanding available bandwidth per mobile terminal. In densely populated areas, the bandwidth per mobile terminal is inadequate and deployment of multiple small cells supports a better communications environment.

C-band Deployment and Testing

C-band spectrum is the perfect balance between low and high bands offering a good compromise between coverage and high throughput for 5G cellular networks. C-band frequency can cover wide distances and has expected peak data rates between 600 Mbps and 900 Mbps. Care must be taken to avoid interference with other RF systems in the same bands.

C-RAN

Massive network densification is required to support the surge in demand for mobile data and support of the Internet of Things (IoT). Future requirements will only be met if the implementation of the whole network is reconsidered, which is achieved by network virtualization in a C-RAN architecture.

FirstNet

Public safety professionals need reliable communications to aid them in their lifesaving missions. Many tasks today require broadband services, i.e. when these first responders need to access data-intensive applications, search databases, or share pictures and videos. There is a clear need for rugged, easy-to-use devices designed to meet public safety requirements, as well as provide advanced features and services that enhance their ability to do their jobs.

Interference Hunting

Interference hunting requires the ability to spot, find and fix a known interferer which is not always an easy task. Not only having the right tools, but the ability to properly identify the issue is key to interference hunting. As strange as it may sound, the first step to solving an interference issue is actually determining that there really is interference. Sometimes there are other issues at play that cause a communications system to work less than optimally but don’t actually involve an outside signal.

Land Mobile Radio (LMR)

Next-generation public safety communications will more than likely pair narrowband Land Mobile Radio (LMR) networks for voice with broadband LTE networks for high speed data. Ensuring these networks are properly installed and maintained is critical to ensuring mission-critical public safety communication and keeping the public safe. The Anritsu S412E LMR Master is the only solution on the market today that provides a quick, easy, and cost-effective means of verifying the operation of both narrowband LMR and broadband LTE networks, and when necessary, diagnosing problems.

LTE

LTE (Long Term Evolution) is a standard for wireless broadband communications for mobile devices and data terminals, based on the GSM/EDGE and UMTS/HSPA standards. The challenge for wireless device developers is to offer the right services and be able to support a variety of systems to ensure their devices can connect globally on any mobile network.

Passive Intermodulation (PIM)

PIM is a growing issue for cellular network operators. PIM issues may occur as existing equipment ages, when co-locating new carriers, or when installing new equipment. PIM can create interference that will reduce a cell’s receive sensitivity or even block calls. This interference can affect both the cell that creates it, as well as other nearby receivers.

Remote Spectrum Monitoring

Interference detection and spectrum monitoring is used to characterize spectrum occupancy. Using a spectrum monitoring system facilitates the identification and removal of illegal or unlicensed interference signals. By monitoring spectrum on a continual basis, problem signals can be identified as they occur in real time.

Shockline NLTL

Nonlinear Transmission Line (NLTL) technology has historically been used for pulse shaping applications and in digitizing oscilloscopes. Over the years it has proven itself to be a highly credible, robust technology. It has been refined by Anritsu for high-frequency use, and complemented with novel monolithic broadband directional bridges, multiplexers, and other key components.

Signal Integrity

Today's signal integrity engineers are challenged to meet high data rates, due to increasing demand for data generated from cloud computing, smart phones and LTE services. The need to minimize costs, and close the loop of simulation and measurement are essential. Fortunately the latest Vector Network Analyzer and Signal Quality Analyzer technologies can provide a solution to these challenges.

WiMAX

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.
