Benefits Of 5G Wireless

While 5G remains an imprecise term today, key objectives for the development of the advances required have become clear. These are as follows:

  • Enhanced throughput – As is the case with Wi-Fi, major advances in cellular are first and foremost defined by new upper-bound throughput numbers. The magic number here for 5G is in fact a floor of 1 Gbps, with numbers as high as 10 Gbps mentioned by some. However, and again as is the case with Wi-Fi, it’s important to think more in terms of overall individual-cell and system-wide capacity. We believe, then, that per-user throughput of 50 Mbps is a more reasonable – but clearly still remarkable – working assumption, with up to 300 Mbps peak throughput realized in some deployments over the next five years. The possibility of reaching higher throughput than that exceeds our planning horizon, but such is, well, possible.
  • Reduced latency – Perhaps even more important than throughput, though, is a reduction in the round-trip time for each packet. Reducing latency is important for voice, which will most certainly be all-IP in 5G implementations, video, and, again, in improving overall capacity. The over-the-air latency goal for 5G is less than 10ms, with 1ms possible in some defined classes of service.
  • Advances in management and OSS – Operators are always seeking to reduce overhead and operating expense, so enhancements to both system management and operational support systems (OSS) yielding improvements in reliability, availability, serviceability, resilience, consistency, analytics capabilities, and operational efficiency, are all expected. The benefits of these will, in most cases, however, be transparent to end-users.
  • Increased mobility – Very-high-speed user mobility, to as much as hundreds of kilometers per hour, will be supported, thus serving users on all modes of transportation. Regulatory and situation-dependent restrictions – most notably, on aircraft – however, will still apply.
  • Improved security – As security remains the one aspect of IT where no one is ever done, enhancements to encryption, authentication, and privacy are expected. It would not be surprising to see identity management (IDM) solutions along the lines of those now at work in many organizations available from at least a few carriers. Current IDM suppliers as well might be more than mildly interested in extending their capabilities to 5G services purchased by enterprises.
  • New spectrum – It is expected that frequencies in the so-called millimeter-wave bands above 30GHz will see service in at least some 5G deployments. Both licensed and unlicensed spectrum at these frequencies is available in many parts of the world. MM wave frequencies are often appropriate to small cells since they require smaller and less obtrusive antennas, and the inherent signal directionality can multiply spectral efficiency. The core disadvantages for MM waves are less applicability to traditional larger cells along with poor object (e.g., buildings) penetration, but such can again be advantages in terms of frequency reuse. Regardless, more spectrum is required given the throughput and capacity objectives that justify 5G development and deployment – present spectral allocations will most certainly not suffice even with the ability to aggregate smaller blocks of spectrum.
  • New enabling technologies – We expect to see higher-order MIMO implementations, sometimes described as “massive” with, for example, 16-64 streams, more aggressive modulation and channel coding, improved power-utilization efficiency, and related advances. Small cells will see frequent application, and the days of large cell towers may be numbered in more densely populated areas. Current trends otherwise at work in networks today, include SDN and NFV, will also see application in 5G, with much infrastructure implemented within cloud-based services. 5G will likely require no major advances in chip or manufacturing technologies, and device power consumption will likely benefit from more limited geographic range even as higher clock rates take a small toll here. Still, much work remains in terms of both technical and feasibility analysis as well as cost, but we see no showstoppers on the horizon. There is no danger of producing another WiMAX that offers marketing hype with no clear advantages over the previous generation, and the overall level of technical risk is low. Perhaps the greatest challenge is schedule slip, as the complex nature of the systems engineering that is required needs more time than many expect.
  • Universal application support – 5G as a wireline replacement will have to support every class of traffic and every conceivable device, from broadcast-quality video distribution to telemetry, implantable medical devices, augmented and virtual reality, and advanced interactivity and graphics – and not just for gaming. The list also includes connected and autonomous cars, remotely-piloted vehicles (drones), public safety, building and municipal automation/monitoring/control, and disaster relief. including relocatable infrastructure with moving cells and support for dynamic wireless meshing. Also in the mix are robotics and IoT devices tolerant of limited data throughput and highly-variable latency. We expect literally tens of billions of 5G devices to be deployed over the next decade or so, so the scale of both the challenge and the demand is clear.
  • Industry growth – Finally, carriers, operators, and equipment vendors of both infrastructure and subscriber devices simply require the deployment of new technologies with quantifiable end-user-visible benefits from time to time in order to continue to grow their businesses. New subscriber units alone cannot accomplish this goal.

In short, 5G is a business opportunity being designed and implemented to provide all of the communication capabilities and performance we expect from a wireline network. Getting to that point, given all of the requirements above, won’t be easy, quick, or inexpensive.

The Today And Tomorrow Of 5G Wireless

By Cradlepoint

If you were running late in the 1980s, you either showed up late or found a payphone and called ahead; today, a quick text — “running late sorry” — does the trick. If you got lost driving in the 1980s, you drove on and on until you got un-lost or stopped at a gas station to ask for directions; today, you have GPS and Google Maps.

It was a different world back then. Today, we are years into a digital revolution. Mobile communication has forever changed the pattern and rhythm of our lives. Technological innovation has been basically nonstop, and it is still going strong. Much vaunted 5G networks, when they finally come online, will deliver super-low latency, impressively high throughput, and incredible connectivity.

Future-facing organizations are trying to predict what the true impact of 5G will be. The question many are asking right now — “Where is 5G, and how long until it can help us?” — is best answered without hype and hyperbole. 5G is coming but it’s not here quite yet.

Companies will pay for 5G
A recent Gartner survey of 200 IT and business leaders indicates that three-quarters of end-user organizations would be willing to pay more for 5G mobile network capabilities, with companies in the telecommunications space being the most willing. However, most companies appear to be struggling to understand 5G, and specifically its potential and its possible effects. A great majority (92 per cent) of organizations asked have no expectation that 5G will lead to a boost in revenues; rather, they look at 5G as a means of naturally evolving their mobile network.

Kinks and misunderstandings
While more than half of those surveyed by Gartner believe they will (or will be able to) use 5G’s enhanced capabilities to drive Internet of Things (IoT) capabilities, 4G will be able to service the majority of IoT requirements for the next five years or so. Companies also appear to be laboring under a misapprehension that 5G will be at full capacity by 2020. In its white paper “State of 5G 2017 and Beyond,” cloud-based network solutions leader Cradlepoint makes it clear that the technology, while getting closer to the mark, is not yet there. In early trials, 5G is excellent for point-to-point, line-of-sight communications between antennas that don’t move. With NSA (Non Stand Alone) architecture and pre-3GPP specifications (adding mobility and interoperability capabilities), today’s 5G can get around interoperability, cell-site handoff, and mobility issues because these deployments are fixed. The data speeds are still tremendous, reaching several gigabits per second and keeping up with fiber speeds.

5G is coming soon
5G is still at least a few years away. In the meantime, organizations around the world are working to make it happen. When 5G finally comes — more than likely in the 2020 to 2022 range — it will be with the noise and fanfare befitting what will amount to a new technological era. On a human level, it stands to be an interesting time, with 5G carriers providing the kind of connectivity and speed and reliability that most in 2017 can only imagine. In everything from streaming video to online gaming to medical device connectivity, the 5G world will be an exciting one indeed.

UN steps in to end marketing war over what 5G means

With mobile operators’ marketing departments already throwing around claims about their 5G services, the United Nations is weighing in with its definition of what qualifies a network as next-generation.

Verizon Wireless will begin delivering “5G” service to select users in 11 U.S. cities in mid-2017, even though some places don’t yet have access to 4G. And at the Mobile World Congress 2017 trade show in Barcelona, companies including Intel, Qualcomm and Ericsson will be promoting their moves towards 5G.

But what marks the difference between one generation of mobile technology and the next?
