FWD Russia's MTS rolls with Massive MIMO for World Cup

Major sporting events are often used as showcases for next-gen networking technologies. Earlier this year, KT conducted a number of 5G tests at the Olympic Winter Games in PyeongChang, Korea. The 5G public demos were interesting but not directly relevant to fans equipped with current generation smartphones.

For the upcoming World Cup, MTS, the leading communications service provider in Russia and the CIS, has pushed ahead with what is described as Europe’s largest deployment of Massive MIMO (Multiple Input, Multiple Output) to date. Organizers are expecting more than 1.5 million international fans in Russia during the course of the tournament.

The Massive MIMO deployment is based on Ericsson, including its AIR 6468 NR-capable radio designed for compatibility with the 5G New Radio standard while also supporting LTE. This Ericsson radio features 64 transmit and 64 receive antennas enabling it to support 5G plug-ins for both Massive MIMO and Multi-User MIMO. 

If the mobile broadband coverage performs as expected, it will be a showcase deployment of Massive MIMO both for MTS and for Ericsson. Last year, MTS awarded a major network upgrade to Ericsson. 

Massive MIMO improves capacity by transmitting data to multiple user devices using the same time and frequency resources with coordinated beam forming and beam steering.

The MTS rollout includes seven of the 11 tournament cities. In Moscow alone, the deployment covers two stadiums and fan zones, Sheremetyevo airport, Red Square, Tverskaya Street and Gorky Central Park.

Saint Petersburg coverage includes stadium and fan zones, Dvortsovaya Square, and Moskovsky railway station. 

The other covered cities are Yekaterinburg, Kazan, Niznny Novgorod, Samara and Rostov-on-Don. Ericsson installed AIR 6468 for MTS at more than 40 sites across the seven cities.

Andrei Ushatsky, Vice President, Technology and IT, MTS, says: "This launch is one of Europe's largest Massive MIMO deployments, covering seven Russian cities, and is a major contribution by MTS in the preparation of the country's infrastructure for the global sporting event of the year. Our Massive MIMO technology, using Ericsson equipment, significantly increases network capacity, allowing tens of thousands of fans together in one place to enjoy high-speed mobile internet without any loss in speed or quality.”

Just last month, MTS announce the first deployment of Licensed Assisted Access (LAA) technology -- again, in partnership with Ericsson. This initial deployment only covered one shopping center in one city (Ufa) but shows the way for a much wider usage of spectrum resources for MTS. 

The new LAA network in Ufa aggregates a 20 MHz band in the 1800 MHz licensed LTE spectrum (4x4 MIMO, 256-QAM) and three 20 MHz bands (2x2 MIMO, 256-QAM) in the 5 GHz unlicensed spectrum. The installation is built on Ericsson’s ERS indoor small cell stations using 1800 (2212) and LAA (2205) broadband radio modules, while Motorola Moto Z2 Force smartphone powered by the Qualcomm Snapdragon 835 Mobile Platform was used as a smartphone. The Snapdragon 835 integrates X16 LTE modem, the first commercial modem supporting the LAA technology. The configuration yielded downlink speeds of 979 Mbps. This marked the first commercial LAA rollout in the region. Qualcomm is also listed as a technology partner.

FWD: FCC Chairman Ajit Pai advances his reform agenda

Building on a series of regulatory reforms adopted last November, the FCC under Chairman Ajit Pai has just adopted a new set of orders aimed at eliminating "unnecessary regulatory hurdles for carriers seeking to move from the networks of yesterday to the networks of tomorrow."

This set of reforms intends to:

  • Streamline the grandfathering of lower-speed data services where the carrier already provides fixed replacement data services at download speeds of 25 Megabits per second and 3 Mbps for uploads.  The streamlined process provides 10 days for public comment, and grandfathering is allowed automatically in 25 days, barring substantive objections.
  • Streamline the permanent discontinuance of services already grandfathered by the Commission for 180 days.  The process will now provide 10 days for comment and 31 days for an automatic grant.
  • Relieve carriers of discontinuance approval obligations for services with no customers and no reasonable requests for service for at least the preceding 30 days.
  • Eliminate burdensome, inflexible, and unnecessary education and outreach requirements for carriers discontinuing legacy voice services in the transition to next-generation IP services.
  • Allow carriers to seek streamlined discontinuance of legacy voice services when a carrier provides stand-alone interconnected VoIP throughout its affected service area, and at least one other stand-alone, facilities-based voice service is available from another provider.
  • Eliminate unnecessary and burdensome or redundant notifications for changes that may impact compatibility of customer premises equipment.
  • Facilitate rapid restoration of communications networks in the face of natural disasters and other unforeseen events by eliminating advance notice and waiting period requirements for network changes in exigent circumstances.

Currently, the five-person commission is missing one member, as the term of Mignon L. Clyburn, a Democrat, has expired. This means the FCC is currently served by 3 Republicans (Chairman Ajit Pai, Commissioner Michael O’Rielly, and Commissioner Brendan Carr) and only one Democrat (Commissioner Jessica Rosenworcel). Not surprisingly, on issues of regulatory reform and "elimination of burdensome rules" the Republicans voted in favor of the measuring, believing it to be business-friendly, while the lone Democrat voted against it, arguing that rules are needed as safeguards for the public.

Ajit Pai put it this way: "Last November, we took steps to accelerate the transition to next-generation networks.  Today, we do even more to modernize our rules.  These reforms can free up billions of dollars which carriers can devote to building new networks instead of propping up old ones.  This is especially important in rural America, where the business case for building broadband is often hard.
The end result of all these efforts will be more rapid deployment, which means better, faster broadband and more competition for American consumers. One example of a reform we adopt today is our decision to streamline the discontinuance process for low-speed data services if a carrier is already providing high-speed broadband—i.e., at least 25/3 Mbps.  This links regulatory relief to the provision of high-quality replacement services, which will both encourage the building of modern networks and ensure that consumers are protected." 

In dissent, Jessica Rosenworcel writes: "When a carrier wants to make big changes to its network, this agency had policies in place to ensure no consumers were cut off from communications.  In other words, leave no consumer behind.  We had rules that required carriers to educate their customers about network alterations and simply answer calls about how their service might be changed when old facilities were swapped out for new.  Today the FCC guts these basic consumer protection policies.  It tosses them out.  It says we don’t need them.  So what does that mean?  Imagine a grandmother living in a rural community.  Her service provider wants to make big network changes because the cost of serving that remote area with traditional network technology now exceeds the revenue.  That makes sense for the carrier.  But for our grandmother, she just wants to know that her phone, her health monitor, and her alarm system—all of which rely on her current network—continue to work.  She wants a heads up.  She wants to be able to navigate change and understand what will require a new contract.  She wants information about what will involve a new service and at what cost... This is mean.  It’s not just mean to my fictional grandmother, it’s mean to millions of Americans who will find that their carriers can switch out services without advance notice or consumer education, leaving them scrambling to find alternatives, reconfigure their homes and businesses in order to keep connected."

President Trump recently nominated Geoffrey Adam Starks, of Kansas, to be the replacement commission for Mignon Clyburn, for a term of five years from July 1, 2017. If approved by the Senate, his nomination is expected to restore a 3-2 balance inside the FCC. Sufficient for Ajit Pai to continue his reform program.

In the meantime, the 3-1 voting balance means that Pai has more leeway. Another order adopted this week with all 3 Republicans voting in favor waives the requirement for small, rural carriers to contribute to the Universal Service Fund (USF) on their broadband Internet access transmission service revenues. Hopefully, these small, rural carriers will pass the savings on to their end customers, thus lowering the cost of rural broadband. On the other hand, it may weaken the Universal Service Fund.

Dell'Oro: Service Provider Router & Carrier Ethernet Switch market contracts

The Service Provider Router & Carrier Ethernet Switch market contracted year-over-year to its lowest level in five years in the first quarter of 2018, according to a recently published report from Dell'Oro Group.
 
The quarterly contraction sets the stage for the first annual market decline since 2012 as telecom and cloud service providers reduce spending on IP infrastructure.

"Over the past two years, the Asia-Pacific region has been a major growth engine for the router market, but in 1Q18, driven in part by saturation in the China telecom market, router demand experienced a sharp decline," said Shin Umeda, Vice President at Dell'Oro Group.  "The weaker China market, combined with price reductions and network architecture evolution in North America, gives us a recipe for a market pull-back in 2018," added Umeda.

Additional highlights from the 1Q18 Router & Carrier Ethernet Switch Quarterly Report:

  • Despite the market's revenue contraction, 100 Gigabit Ethernet port shipments grew more than 35% year-over-year.
  • Cisco was the top ranked vendor in 1Q18, followed by Huawei, Nokia, and Juniper. These four vendors accounted for more than 90 percent of the market revenue in 1Q18.

IDC: Worldwide Quarterly Security Appliance sales up 14% in Q1

Worldwide vendor revenues for security appliances in the first quarter increased 14.3% year over year to $3.3 billion and shipments grew 18.9% year over year to 838,098 units, according to IDC's Worldwide Quarterly Security Appliance Tracker.

"The first quarter of 2018 exhibited strong growth for network security due to consistent double-digit growth across nearly every region and continued momentum from UTM as vendors reported $240.6 million more in revenue for 1Q18 than in 1Q17. Firewall and UTM are the strongest areas of growth as network refreshes drive perimeter security refreshes and as vendors add new features and improve performance across all product lines," said Robert Ayoub, program director, Security Products.

Some highlights from IDC:

  • The Unified Threat Management (UTM) sub-market reached record-high revenues of $2.1 billion in 1Q18, a year-over-year growth of 16.1%. The UTM market now represents more than 53% of worldwide revenues in the security appliance market.
