Accelerating the Virtual Infrastructure for Open RAN

Dell Technologies and Altiostar partner to accelerate adoption of open and virtualized RAN Over the last several years, 5G has been a cornerstone of the telecommunications industry technology development  – defining a radio air interface and technology architecture for the core network. Now that the promise of 5G is becoming a reality, industries looking to transform are implementing new use cases for 5G that are defining new network “edges” that foundationally change traffic flows and data analytics pipelines in Telecom networks. The snowball effect of the NFV transition started in 2012 with a focus on 4G … READ MORE

Edge Data Centers: Recent European Deployments and Looking Ahead to MWC19

We are just a few days away from Mobile World Congress (MWC) Barcelona and the big themes are already taking center stage – 5G, IoT and automotive being a few of them. As Tom Burns, SVP and GM of Networking & Solutions, mentioned earlier this week, 5G is not simply an evolution from 4G. 5G requires massive transformation and demands new distributed architectures. Simply put, in addition to internal operational efficiency and scalability, 5G needs edge computing to reduce latency and drive real-time, automated decision-making. Our Extreme Scale Infrastructure (ESI) team has been an active leader … READ MORE

How 5G Relates to SDN and NFV Technologies – Part I: Introduction and History

Will 2019 be the year when 5G takes off?

We are just a few weeks away from the Mobile World Congress (MWC), where I have absolutely no doubt that 5G will be everywhere, including at the Dell EMC and VMware booth. But what is 5G exactly? And what does 5G have to do with the NFV and SDN technologies we covered in previous blog posts?

There is a lot of confusion surrounding 5G. For example, if you use AT&T and, like me, live in Dallas, Houston, Oklahoma, Indianapolis, New Orleans or Charlotte, your phone might display something like this:

So does this mean that 5G is up and running in U.S.? Well, yes and no.

5G Availability

There is a live 5G network in the cities I mentioned but you need to use a 5G hotspot to access it, even if you have the latest iPhone Xs, Samsung Galaxy or latest LG. None of these devices have a modem or antennas that will work on a 5G network.

So is having “5G” on your phone display misleading?

Not altogether.

It is true that they have been upgrading cell towers with TLE-advanced features across the nation over the last year, including things like LTE (Long Term Evolution), advanced features like 256 QAM (Quadrature Amplitude Modulation), 4X4 Multiple-input and Multiple-output (MIMO), 3-way Carrier Aggregation, etc. A more accurate display on our phones, therefore, would read “4G-LTE for Long Term Evolution,” not “5G” (those marketing folks, again! 😃).

To be fair, other companies like T-Mobile did something similar back in the day with 3G-4G, but it misled some customers. Verizon already has 5G working on several test cities (e.g., Sacramento, L.A. and Houston) and like AT&T, the only way to really access it is through a hot spot or with prototype cellphones since we don’t have 5G compatible phones yet.

Why Do I Think this Will Be the Year of 5G?

All major U.S. operators are working against the clock to have 5G coverage in most metropolitan areas by year’s end. In addition, we’ll see the launch of the first commercial cellphones in the 3Q-4Q 2019, which I am sure we will preview at the MWC 19 in Barcelona. We are also reaching a point where both NFV and SDN technologies are reaching maturity and we can even see a consolidation of the number of SDN controllers as well as NFVI components, while the number of available VNFs are exploding.

We will see in part two of this blog series how 5G and NFV go together like peanut butter and jelly, when I’ll explain the concept of network slicing, a network technology that enables network operators to provide networks on an “as-service-basis,” allowing a single physical network to be portioned into multiple virtual networks and multiple types of customer services.

A Brief History of Mobile Cellular Communications

Okay, Javier, all of that is great, but can you get into more details on what exactly 5G is and the differences compared with 4G?

5G is the fifth generation of cellular mobile communications. The first generation (1G) of analog telecommunications standards were first launched in Japan’s NTT in 1979 and later introduced in the 1980s around the world (MNT system). Some of us may remember the Motorola DynaTAC 8000x introduced in 1984 (see below and its comparison of technologies).

The second generation (2G) started in 1991 and exploded worldwide at the end of 1990. Four years later, manufacturers formed the GSM Association. Third generation (3G) was the first mobile focused on data, not just voice and texts, and started at the beginning of 2001. The fourth generation (4G) started in 2007 and became popular worldwide after 2010.

First and Second Phases of 5G

So back to the present and 5G. The first phase of real 5G started in May 2018 with the Release-15 of whitepaper specifications by the ITU (International Telecommunication Union). ITU is made of 193 countries and has more than 800 board members, which gives rise to the reason why it takes a bit of time for them to collectively agree on a standard. The positive? It eliminates the issues we had in the past with GSM/TDMA – the dual competing technologies.

The second phase of 5G and latest global standard is Release-16 due to be completed by April 2020 as a candidate for the IMT-2020 technology. This second standard will increase speed and bandwidth exponentially, compared to the previous generation, demanding speeds of up to 20 Gb/s and frequencies of at least 15 Ghz or higher. The Third Generation Partnership Project (3GPP) is going to submit 5G New Radio (NR) as standard that will include the possibility to use lower frequencies (600 Mhz to 6Ghz versus the 15 Ghz explained before). Lower frequencies can enable telecom companies to reuse existing frequencies licenses without having to buy additional ones, reuse some of the old hardware, and get better coverage. However this 5G NR software on 4G hardware is only between 20-50% faster than traditional 4G. Regardless, if this new software is loaded on new Enhanced Mobile Broadband (eMBB) hardware, the speed bump can go up to 150% on lower frequencies and up to 12-20 times on the higher than 6Ghz frequencies.

A Final Comment on Frequencies

When I explained that lower frequencies increase coverage I was speaking to having better penetration, and by that I mean getting the signal from a tower to your cellphone though a wall, building, etc… It’s rare you’ll have an open and unstructured line of sight with a tower if you live in an urban area, and it’s one of the biggest challenges of 5G. The second biggest challenge is the operator’s need to balance performance and CAPEX costs to achieve profitability and sustainability as the cost per GB of data keeps decreasing.

NetScaler SD-WAN Virtual Path Unstable

Metering on the 4G link paths is turned on if there is at least 1 non-metered path that is in GOOD state. When this happens, metering is enabled on all paths on the 4G link and these paths are not used for control info. In other words, when at least 1 ADSL link path is in GOOD state, metering is enabled on the 4G link paths

while metering is enabled on the 4G link paths. If the quality of the ADSL link paths deteriorates to the point that the bandwidth on these paths is not sufficient for control info, the VP goes DEAD. Ss soon as the VP goes DEAD, the control plane disables metering, the 4G link paths are then used to send control info the VP goes back up.

Interesting that the swedish ISP Telia is there. You know, the ISP that makes Seppos look like backward savages.

https://www.ericsson.com/en/news/2017/4/top-speeds-reached-in-telias-commercial-network

“Residents in Stockholm can soon experience record-setting speeds in Telia’s commercial network, thanks to recent tests by Telia and Ericsson. The tests pushed 4G networks to 757Mbit/s to prove readiness for 5G, and for advanced applications and services like Virtual and Augmented Reality.”

What speeds do you get in Bumfuck, Ohio, or even in LA?

Note, 4g/5g refers to mobile internet.

Lightning Speed: The Profitable Future of 5G

EMC logo


We’re poised to see a quantum leap in telecom technology – and 5G will be at the center as the most powerful, efficient, and intelligent set of mobile phone and data communication capabilities to date.  Telecom providers need to begin transforming their networks for the 5G future today, while continuing to confront myriad legacy struggles ‒ including 4G/LTE build outs, shrinking customer revenue, and increased competition from OTT (over-the-top) competitors.

Preparing for 5G while keeping the lights on for today’s business is a heavy lift, but progress is already underway. The good news is many providers are further along the 5G migration path than they may realize. According to IDC[1], 68% of telecom leaders are actively implementing or planning network virtualization.

Network functions virtualization (NFV) and software-defined networking (SDN) are key to updating the three network areas that providers need to transform when creating a 5G network:  the radio access network, the core network, and the service creation layer.

NFV and SDN help create a composable network core that decouples the user and control planes, allowing services and applications to be moved closer to the network edge and providing the flexibility to meet the high bandwidth, low latency requirements and scale needed to support 5G.

What business benefits will 5G deliver for telecom providers?  Running a faster network enables more rapid, comprehensive data collection, which can increase revenue, enhance network performance, improve customer experience and retention and accelerate new services and revenue opportunities.

These advantages are not a given.  To experience the full power of 5G, providers will need to adopt an “intelligence-first” approach to managing core networks. Providers should begin work now to increase their network intelligence and implement analytics as this investment will pay dividends in the short and long terms. Real-time network insight – gleaned from continuously streaming session control, subscriber events/data, and other data events ‒ is an essential enabler of network and operational intelligence.

Below are just a few examples from a Dell EMC study that show how real-time analytics can help providers streamline networks and optimize revenues[2]:

  • One provider reduced call center traffic and saved $28 million in unnecessary data usage rebates after providing call center agents with a detailed customer data dashboard
  • Another enterprise cut the number of calls about mobile data usage that escalated to second or third line support and saved $7 million annually on a base of 10 million customers
  • A third provider increased conversion campaign results by 30% by identifying dynamic segments of customers eligible for a data plan upgrade and sending personalized offers in real-time

By combining real-time analytics with the flexibility introduced by network virtualization, telecom operators can stream network data in real-time and generate the insights needed to achieve results like these and much more.  But how can providers rapidly process and analyze the massive amounts of network data to unearth such vital and valuable insights?

Dell EMC has partnered with Affirmed Networks to create an industry- first and “intelligence first” implementation of integrated virtual probes with Affirmed’s Virtual Evolved Packet Core that streams data in an open format to Dell EMC’s underlying platform that can provide complex event processing on the data in realtime or store it in a data lake for historical analytics.  View our infographic for more information and to see more real world examples of what virtual probes and data analytics can do for telecom.

The future of 5G is closer than we think.  A real-time analytics investment today can put telecom providers in a strong position to leverage 5G networks and increase network intelligence well into the future.
