The VIAVI Seeker X leakage detector provides the agility to monitor leakage anywhere in a channel lineup, with the sensitivity and speed to accurately detect leaks that other systems miss.
With support for up to 4 concurrent monitoring frequencies from 130-1220 MHz including OFDM support, Seeker X affords operators complete flexibility in defining downstream channel lineups, while providing true full-spectrum leakage detection.
Seeker X will detect tagged leaks and ignore untagged leaks, saving time from false alarms from signals not originating in your system, including overbuild situations. In addition to legacy Seeker D tag signals, Seeker X detects the revolutionary new digitally tagged carrier to provide unmatched leakage sensitivity and positive leak detection. This allows more thorough and accurate coverage of your plant in driveout testing and much more efficient find and fix processes for techs in the field.
Transition to distributed access architectures is simplified by virtualized tagging capabilities supported by most major R-PHY, R-MACPHY, and R-CCAP vendors. With this approach, no specialized hardware is required in the hub, and technicians use the same Seeker leakage detectors and work processes regardless of node type.
Seamless Transition from Seeker-D
Seeker X detectors and mobile mounts can be dropped into systems currently using Seeker D’s with no change to existing monitoring and find/fix processes. These new Seeker X units can benefit from the increased speed, sensitivity, and OFDM detection on their own, and can monitor two extra tagged frequencies if CT-4 taggers are swapped out for Seeker-D compatible CT-X units.
Regardless of the system architecture or channel lineup, Seeker X provides all the capabilities to find and fix leaks quickly, accurately, and effectively.
When home network quality is unreliable, customers become dissatisfied and are more likely to churn. At the same time technical complexity is increasing, but technician skill and experience at the installation service tier is typically minimal. It’s never been more important to have quick, effective troubleshooting tools that enable techs to quickly and efficiently verify performance as advertised.
The ONX 220 is fast, complete, and follows up testing with simple cloud data storage to enable real-time close-out and reporting.
Flexible and Affordable

Estamos solo en la mitad del 2019, y ya estamos dando forma al prometido año del 5G. Verizon, AT&T y Sprint han lanzado sus redes 5G en areas especificas de USA; Swisscom esta ofreciendo servicios comerciales de 5G en las mayores ciudades de Suiza; EE cambio a 5G en algunos ciudades el ultimo mes; y en Corea del Sur, SK Telecom, KT y LG Uplus anuciaron sus primeros suscriptores 5G en Abril.
Sin embargo, conseguir suscriptores 5G es solo una arte de este rompecabezas. Es sorprendente la cantidad de juegos de Realidad Aumentada y video en vivo en en los smartphones, habra una gran cantidad de IoT y casos de uso de IoT, los cuales realmente apalancaran el crecimiento comercial de 5G. Diferentes sectores verticlaes y diferentes casos de uso requeriran diferentes tipos de conectividad y los operadores estaran contractualmente obligadas a asegurar los servicios ofrecidos. Los clientes (y sus usuarios finales) esperan que los operadores soporten efectivamente las Comunicaciones Masivas Tipo Maquina (en ingles mMTC), el ancho de banda movil mejorado (en ingles eMBB) y las comunicaciones de baja latencia ultra confiables (en ingles URLLC).
La unica forma en que los operadores estaran habilitados para entegar estos acuerdos de servicio estaran optimizados para la red 5G, y garantizar que el masivamente diverso ecosistema IoT corra efectivamente, es por medio de la llamada Segmentacion de la Red.
Que es segmentacion de la red?
Segmentar la red significa crear una red independiente end-to-end sobre una infraestructura virtual, compartida, y que pueda atender las demandas y funciones de multiples casos de uso 5G o multiples tipos de comunicacion. Una analogia para entender esto mejor es un policia acompañante que crea un camino limpio, libre de trancones a traves de una via congestionada. El camino estara limpio y adecuado a las necesidades especificas del acompañante, por ejemplo atravesar una calle ocupada en forma rapida, confiable y perfecta, con los otros vehiculos priorizando al acompañante sobre sus propios movimientos.
Why test network slicing now?
5G deployments are still few and far between, so operators should use this current period to test and assure the architectures and approaches which will be so vital to its success across different vertical markets and customer segments. When testing network slicing, operators must consider:
Testing a 5G network loaded with multiple types of data traffic in a real-world scenario is near impossible. Imagine trying to test a URLLC use case like connected cars, for instance, which will involve a network slice supporting thousands of vehicles and ensuring their safe, regulation-complying movement within smart city environments.
For operators to prepare themselves for the 5G use cases of the future they must test network slicing in a virtual, lab environment. VIAVI Solutions has developed end-to-end, RANtoCore test and validation solutions capable of emulating the 5G core network as a whole, individual nodes such as the UPF, SMF, AMF as well as multiple other functions.
Combining TeraVM and TM500 provides operators with a solution to the network slicing challenge, which is unique in the T&M industry, enabling service providers to ready their networks for 5G, get ahead of the competition, and future-proof their business.
To find out more about the importance of testing network slicing, learn how VIAVI is supporting major operators globally, and discover the benefits of partnering with us, head to our dedicated whitepaper.
Invariably, things change. Profound I know, but even in the world of the venerable IRIG timecode there is a new search engine contender, iRig. Granted, a new guitar interface adapter for your smart phone app is a far cry from a waveform used to synchronize instrumentation, but even in IRIG there are revolutionary changes happening. To which we can collectively ask, “why did it take so long to do something so obvious?”
Here’s a little backstory: IRIG stands for Inter-Range Instrumentation Group, but is commonly the term used to refer to the waveforms passed through coaxial cables used to synchronize the time-of-day on test instrumentation used on military test ranges. These IRIG timecodes date back to mid-last century when military test ranges needed a way to time align all sorts of measurement equipment, videos, radars, strip chart recorders, etc. for flight tests conducted over the vast geographical expanse of the test range. While the formats and accuracy of the IRIG timecodes have evolved over time, IRIG in general is still very widely deployed.
For decades, generating an IRIG timecode took discreet electronic hardware and components to generate the waveform. Flexibility was characterized by DIP switches to choose IRIG formats and plug-in modules filled with BNC connectors inserted into 1U, 2U and 3U rack mount chassis. In fact, as far as I know, with one exception, all solutions offered today still deliver IRIG this way. Of course, it’s that one exception that, like a guitar interface to your smartphone, changes everything.
Innovation is often driven by someone asking, “Why can’t I just do this instead?” This is exactly what happened in IRIG timecode generation, selection and output in the Microsemi SyncServer S650. A bright timing scientist asked, “Why can’t we just take everything we do in IRIG hardware and program an FPGA to do it?” Marketing then comes along and promptly agrees with innovative ideas they don’t have to figure out how to make work. They give it a name – “FlexPorts” – and a new era in IRIG timecode generation is born in the Microsemi SyncServer S650 FlexPort™ option.
I must say that FlexPorts are obvious, innovative and cool. Imagine a module with a collection of BNC connectors that plugs into the 1U SyncServer S650. The module has its own web page in the intuitive SyncServer web GUI. You can navigate to the module web page, which is organized like the physical BNC connectors on the module, and merely select from drop down menus which IRIG signal you want to output from each connector. Configure each connector waveform output any way you please as it supports a lot more waveforms than just IRIG, press “apply” and viola! Those signals are all instantly being generated and output, all synchronized to the main clock and as perfectly aligned to each other as you can get. No changes to physical hardware, no removing modules and flipping DIP switches, no installing a module that has 3-4 connectors when you just need one. FlexPorts really are a pretty cool technology.
At this point, I suspect that you might be a bit underwhelmed, and that’s understandable. The FlexPort concept is a bit obvious and the next question is probably “Why did it take so long to figure that out?” Well, like the wheel, its benefits were obvious to some, but not to all. The Smithsonian asserts that wheels were used as potter’s wheels for 300 years before someone used them on a chariot. Not sure what a wheel-less chariot looks like, much less rides like. And kudos to the guy that figured out a stone potter’s wheel on a chariot was a non-starter and that wood was a better choice, but I digress. We’re now very glad we have wheels and we’re very glad we figured out how to use an FPGA to generate IRIG timecodes on demand instead of expensive, inflexible, purpose built IRIG timecode modules with discrete hardware parts.
If you want to learn more about FlexPort technology and what it can do, have look at the FlexPort Technology for SyncServer S650 application note here. If you have been at all involved with IRIG timecodes I think you’ll agree that while iRig for your guitar app interface may be novel, FlexPort technology for saving time, money, and ease-of-use in deploying a precise IRIG time synchronization solution like the SyncServer S650 makes a lot of sense.
The UK government has recently permitted the use of Huawei technology in the nation’s mobile networks (albeit, the radio access network or “non-core”). Without getting caught up in a debate about security, we should focus on what this signifies to the industry; that the UK is serious about 5G, and does not want to limit its options of technology suppliers in the race for 5G commercialisation.
The UK has maintained its focus on 5G development for a number of years. In 2015, the 5G Innovation Centre (5GIC), which has received considerable government funding, was opened at the University of Surrey. Since then it has supported pioneering research into the benefits of, and the obstacles preventing, the adoption of 5G technology. Supported by consultants, such as our very own Dr Li-Ke Huang and major telcos such as EE, Vodafone and Samsung, 5GIC epitomises the UK’s commitment to 5G.
However, the government’s investment in 5G doesn’t stop there. In March 2018, it announced the winners of a 5G test bed and trials competition, which saw a number of other enterprises, universities and authorities receive grants of between £2 million and £5 million to test 5G applications. In November, almost £7 billion was earmarked by the government to make 5G and fibre roll-out a reality over the next 10 to 15 years. It’s also worth noting that the UK was quick off the mark to auction 5G spectrum, a process which started in March last year.
The UK has clearly demonstrated its continued dedication to becoming a 5G leader. However, last week’s news regarding Huawei was a big wake-up call to technology firms, highlighting the importance of demonstrating their security credentials in order to play a role in the nation’s new next generation networks. Ericsson, Nokia, Huawei, Samsung and ZTE are among the major network equipment manufacturers (NEMs) that will be considered for 5G networks. However, it is very common for the NEMs to white label technology from other technology vendors. The objective for these vendors is to prove to both the NEMs and the mobile operators that their technology can make a difference; and do so quickly, in line with the UK government’s ambitious plans.
Telcos warm to multi-vendor technology
Mobile operators are increasingly open to using network hardware and software from multiple technology providers within their networks – giving them a selection of best in-class solutions. Open initiatives such as openRAN (oRAN) and Telecom Infra Project (TIP) are providing operators with blueprints for the implementation of multi-vendor technology across the network. This approach can lead to improved flexibility, scalability and cost saving for operators, and new opportunities for vendors, big and small.
With the first wave of 5G networks focussed on non-standalone technology – i.e. networks that connect to new 5G radios and the LTE core – there is an opportunity for RAN vendors to showcase their credentials in this first wave of 5G deployments. To do this successfully they must test and validate their technology against a range of real-world 5G applications.
A testing time for 5G vendors
5G technology presents a range of new innovations, from the use of active antennas, to MIMO and 3D beamforming, software defined components, and large carrier bandwidths. However, these innovations also bring new challenges when it comes to verifying the performance of the technology.
Massive MIMO, for example, requires the use of large number of antenna elements which will add a huge amount of complexity for performance testing and validating the radio frequency environment. The purpose of Massive MIMO is to help deliver high data throughput to large number of users. To achieve this requires performance testing under realistic conditions, with large number of end user devices attached to the network. New technology, such as Massive MIMO, must not only be tested in silos, but also run against a set of core network test cases within a loaded network environment.
It is now vital that 5G manufacturers test their technology in a lab before bringing it to market to account for any environmental factors that may affect the performance in a live network. If they can prove that the technology has undergone scrutinous validation at scale with a high number of both 4G and 5G carriers, under real-word conditions without QoE degradation, they will be considered favourably by operators, or the NEMs, in their network plans.
With telcos now moving from testing to field trials, technology vendors of all sizes must quickly look to offer future-proof high performance and differentiated propositions. Validating technology against live 5G applications is an important means of proving that it is primed for today’s networks. As a pioneer in test and measurement equipment and dedicated to the development and monetisation of network services, VIAVI is the ideal partner for technology vendors as they look to enter the 5G network market. VIAVI can help these businesses address challenges now – and do so simply, quickly, and cost-effectively – allowing them to demonstrate that they can make a difference in operator networks as they race towards commercialisation. VIAVI has experience in working with operators and with all the major NEMS around the world, it is best placed to validate an operator’s network from end-to-end ensuring the best performance irrespective of the RAN supplier, and core network components vendors. VIAVI can also ensure that legacy 4G services and KPIs are not compromised, especially with new low complexity devices and enhancements such as the wave of Rel-14+ Cat-M and NB-IOT. This becomes vital as 4/4.5 to 5G interactions grow and network complexity increases.
