Viavi Solutions (formerly JDSU, Arieso and Network Instruments) is very active in LTE and helping to advance the technology … how has LTE progressed since last year? 

LTE as a standard continues to evolve to meet the growing capacity and coverage demands of mobile consumers. With LTE Advanced and LTE Broadcast being two examples. Yet it is the area of VoLTE which has probably seen the greatest change from last year. At the event last year many operators were planning their VoLTE roll-out and engaging their technology partners such as Viavi on the challenges to address and ensure they deliver on the high expectations of VoLTE. Now, we have many operators who have either deployed or are very close to deploying. There is also the area of the relevance of voice today – many people of course have an iPhone or other Smartphone and use a multitude of methods to communicate –  certain generations don’t talk at all! So, the industry has had to appreciate that VoLTE needs to be integrated into the way people communicate today.

What are the top VoLTE challenges?

Working closely with our mobile operator customers and building on our experience with IP based voice services as well as RAN and Core network challenges I would say the top three challenges are:

  •  Voice Quality – measuring end-to-end (E2E) voice quality is fundamental to understanding the customers quality of experience (QoE). Knowing what metrics are important, where to measure and quickly finding the root cause of voice quality affecting issues.
  • Handovers – when you move out of an LTE service area and have an active VoLTE call, the user will want to continue with that call. SRVCC seamlessly maintains calls when a mobile user moves from LTE to non-LTE coverage areas. Of course, there is the potential for things to go wrong and calls to get dropped. Also, if the user is not supporting VoLTE but is using LTE, when they receive a call the phone the network need to fall back (CSFB) so that both data and voice are non-LTE.
  • Location – not only knowing what service is being provided to the consumer but also from where so that you can determine, for example, VoLTE hot spots  – that is where there may be too many dropped calls or handovers have failed. By accurately geo-locating voice quality metrics you can make better business decisions on service delivery.

 Presentation theme/message at the event?

In addition to introducing Viavi Solutions to the audience, Viavi will be presenting in 3 key areas, namely: VoLTE, HetNets and Network Optimization. The theme of the VoLTE presentation is how to address some of the key VoLTE challenges and ensure the subscribers gets an exceptional VoLTE service. We will be exploring voice quality- passive measuring, active measuring – how integrating handset data with core data and then geo-locate that information to maximize the business impact of the service. The E2E view of the service from device to RAN to backhaul and core. For HetNets we will be discussing workforce automation and how to ensure cell site turn up to be most cost-effective without impacting quality. Network Optimization will build on the extreme non-uniformity in cellular networks and how subscriber-based, location-aware predictive optimization is needed.


Meet Paul and the Viavi team at the upcoming LTE North America, in Dallas, next November 17th-19th!

Interview: Head of Mobile Access: Deutsche Telekom: “[LTE Radar] is nothing less than a powerful new enabler that will significantly enhance value of the mobile access.”

Is ‘LTE Radar’ a rare example of forward thinking from the telcom community? Thomas Henze, Head of Mobile Access, products & innovation, Core Telco Products, at Deutsche Telekom, certainly thinks so and in this interview he tells us more about the fledgling technology and why he’s excited about the impact it will have on consumers and the prospects it offers to operators.

Henze will be speaking on Day One of the 10th annual LTE World Summit, the premier 4G event for the telecoms industry, taking place on the 23rd-26th June 2014, at the Amsterdam RAI, Netherlands. 

Can you tell me more about “LTE Radar” and LTE proximity services?

Technically proximity services consist of two components: broadcast and discovery. This means devices will be enabled to a) broadcast digital information into their proximate environment in order to “become aware” and b) discover similar information, about and from other devices.

Integrating control of this functionality into the mobile network as well as using LTE on licensed spectrum for the transmission makes it a powerful telco grade solution.

As for the terms, at Deutsche Telekom we refer to our related project as “LTE Radar”, a name which is especially refers to user’s perception of the discovery function.  It’s not necessarily our final product name, rather a working title. The technology behind “LTE Radar” is pretty much based on Qualcomm’s “LTE Direct” concept and is currently being standardised by a 3GPP project called “Prose”.
