Accelerating 5G: Taking Gigabit LTE to the Masses

Gigabit LTE (LTE networks, services and devices supporting theoretical peak speeds of a Gigabit or more) has been a big part of 5G discussions in 2017.  But it’s also – as the name implies – an evolution of LTE.  3GPP R13 LTE-Advanced Pro, to be specific.

It’s fair to ask, then, what’s the link to 5G?

While it would be technically inaccurate to position Gigabit LTE as a 5G technology, there’s no denying that it will support 5G rollouts and services.  As 5G rolls out in targeted pockets, Gigabit LTE will ensure consistent network-wide user experiences.  Likewise, as service providers investigate the specific IoT and broadband use cases 5G will support, Gigabit LTE will help them understand the options and opportunities ahead of them not to mention fundamental 5G technologies that start getting introduced into the network with Gigabit LTE.    Continue reading “Accelerating 5G: Taking Gigabit LTE to the Masses”

TM Forum Live! 2017: Bringing Telco IT Up to Real-Time Network Speeds

David Snow – Principal Analyst, IP Services Infrastructure

Summary Bullets:

  • The 2017 edition of TM Forum Live! is in Nice, France next week, and with the nature of telco IT-network interactions undergoing radical change, the ‘Live!’ suffix is more appropriate than ever.
  • NFV MANO, advanced network analytics and 5G network slice management are all hot topics with operators and vendors alike, and all play their part towards the goal of autonomous network operation.

In the same way that Mobile World Congress has steadily evolved over the years to be far more than just a mobile network event, next week’s annual TM Forum event has continued to expand. It used to be the place for ‘telco IT’ systems and carrier operation based on OSS and BSS, and if there was any direct linkage to the telecom network, it would be largely in terms of non-real time network management interactions. In fact, the nearest to ‘real time’ these network-telco IT interactions operated at was as a continuous and one-way ‘blast’ from the network to the telco IT systems delivering such things as fault reports. OSS and carrier operations staff then had to filter all these reports, prioritize them and finally decide what to do about them; that was (and largely still is) very far from real time. Now, however, everything is changing with the advent of network functions virtualization (NFV) and NFV management and orchestration (MANO). These new telco IT-network interactions must be both two-way and very close to real time for the network to remain operational at all, similar to the manner in which some modern fighter aircraft would literally fall out of the sky without automated, real-time aerodynamic trimming.

Accelerating 5G: Bringing NR to Reality

Every new generation of cellular technology has come with its own, new, air interface.  5G is no different, introducing 5G New Radio (NR). And, as with so much of 5G, 2017 promises to be a big year for 5G NR.

Long before AT&T announced 5G Evolution services based on LTE technologies last week, it was clear that service provider strategies and vendor positioning, alike, include LTE technologies as new air interfaces in their 5G service and marketing plans.  With LTE continuing to evolve, its inclusion in 5G discussions makes sense (a topic we’ll come back to).  But it also begs the question of why a new air interface for 5G is necessary.  Beyond any interest in delineating a new technology with a new air interface, 5G NR promises a number of important features and functionalities: support for diverse spectrum, including low-band (sub-1 GHz), mid-band (1 to 6 GHz) and high-band, mmWave (24 GHz and up) assets; lower latency; added network capacity; improved spectral efficiency (lower cost-per-bit); improved service uniformity (EG, at cell edge); and the flexibility to support 5G’s diverse use cases (massive IoT, critical communications, and enhanced mobile broadband) with one unified design.

The 2017 Story

Against this backdrop – and a general interest in moving 5G forward – it’s not surprising that operators including AT&T, Verizon, and SKT have committed to commercial and pre-commercial 5G deployments this year incorporating mmWave spectrum and an air interface beyond LTE.  It would be wrong to call the technology used in these launches “5G NR” since these operators aren’t waiting for the 5G NR specifications to be complete.  Regardless, these launches are important, if only because they point to three key realities: enhanced mobile broadband (eMBB) as the first 5G use case focus; demand for moving quickly on implementing new 5G air interfaces; the progress made to date in bringing that new air interface to life.
