5G - Everything, Connected

Overcoming the current limitations of 4G is the principal goal of 5G, a concept that is both an evolution of wireless networks to meet future demands for data and a revolution in architecture to enable a cost conscious network that can be efficiently scaled. The technologies being proposed are also trying to look into the future and support what the networks and demand will look like in 2022 when 5G networks are expected to be deployed on a large scale.

Base Station Testing

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.

Bluetooth

By eliminating wires and simplifying connections between everyday appliances, Bluetooth wireless technology influences our lives in many ways.

Anritsu provides leading-edge technology incorporated in test and measurement solutions for the optical, RF/microwave, wireless, and datacomm/telecomm industries as well as unique solutions in electronic and optical components.

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.

The Internet of Things (IoT)

IoT, along with 5G, are “the next big thing” in the Tech World. Many industries are excited about the opportunities it presents, worried about the changes and perplexed by the challenges. If you ask 10 people what The Internet of Things means you are likely to get 10 different answers ranging from Big Data to the connected car and autonomous driving. Still, one common denominator remains: The Internet of Things relies on products that are physically connected to the outside world. Be it wired or wireless, without this connection the Internet of Things will not exist.

Ethernet

Ethernet is a communications standard used primarily for the Internet. With the increasing popularity of smartphones and the resulting increase in mobile data, the demand for higher Internet speed has driven an increase from initial speeds of 10 Mbps to 100 Mbps up to 1 Gbps to 10 Gbps and higher. Data centers, handling core data networks between cities as well as metro networks within cities, are already implementing upgrades to 40 Gbps and 100 Gbps. In addition, discussions of ultra-fast Ethernet speeds of 400 Gbps are in progress

Anritsu's Network Master Series test platform is ideal for developing and manufacturing new devices that support stable communications through the use of high-speed Ethernet and for troubleshooting and maintenance of communications networks.

Fibre Channel

Fibre Channel is a communications standard featuring efficient and fast transfer of the large data volumes required by financial institutions, data centers, etc. Cloud services, using data centers accessed via networks, are increasingly popular for storing data and are generating an increased demand for Fibre Channel testing.

Anritsu's Fibre Channel test function is designed to meet this growing need.

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.

TDD/FDD Access

LTE standards support the use of both Time Domain Duplex (TDD) and Frequency Domain Duplex (FDD) from the same set of standards, and with the same air interface characteristics.

MIMO

Multiple Input Multiple Out (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 / 4x2 MIMO with spatial multiplexing, the user data is separated into two data sets each fed to two / four 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.

Microwave Components and Device Characterization

Developing next-generation components and devices incorporating high-speed LTE and 5G design schemes requires highly accurate test solutions that can measure complex signals fast and efficiently. Anritsu has the test answers for the most difficult design questions to ensure products operate in any application, from M2M modules for IoT systems and connected cars to high-bandwidth commercial wireless networks and defense systems.

OTDR

Anritsu's comprehensive OTDR（Optical Time Domain Reflectometer）range ensures fast and highly accurate measurements of optical fiber cables with a unique range of handheld, benchtop, and OEM module solutions.

OTN, SDH/SONET, PDH/DSn

When using Ethernet communications, the data is commonly transmitted by mapping once, using the Optical Transport Network (OTN) communications standard, and is then returned to the Ethernet standard by demapping at the transmission destination.

Using OTN like this has several advantages:

A high-reliability network can be configured by using error correction during transmission (Forward Error Correction: FEC).
Using the OTN switching function supports data transmission to the destination with assured reliability.
Smooth support is assured for legacy standards like SDH/SONET, PDH/DSn, etc., as well as for as-yet-unknown future data mapping standards.

Anritsu test equipment supports OTN FEC function inspections in line with ITU-T standards, while also offering strong support for current SDH/SONET, PDH/DSn inspection standards.

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.

SyncE

The ITU-T SyncE (Synchronous Ethernet) and IEEE 1588 v2 standards support synchronized timing of data between base stations in order to permit uninterrupted transmission as the Smartphones move between base stations.

Anritsu’s Ethernet test solutions support standard Ethernet communications and provide the ideal platforms for verifying, developing and troubleshooting SyncE and IEEE 1588 v2 functions used by base stations.

TD-SCDMA

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.

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.
