Google plans free public Wi-Fi in Mexixo

Google is launching free public Wi-Fi at locations across Mexico.

Initially, Google Station will be available in 60+ high-traffic venues across Mexico City and nationwide, including airports, shopping malls and public transit stations. Google plans to reach 100+ locations before the end of the year.

Google already provides public Wi-Fi in India and Indonesia.

The tower companies will let us know when 5G rollouts gets real - part 2

Preamble: Network densification is a key premise of 5G architecture. Once the rollouts of 5G networks begin in earnest, we should expect to see many more cell sites in urban areas across the world, so one way to measure the progress of 5G rollouts will be to keep an eye on the companies that actually will handle the deployment of physical equipment on the streets.
American Tower is one of those companies.

At this week’s Mobile World Congress, American Tower, in partnership with Philips Lighting, is announcing a street ¬¬¬pole designed to meet the capacity challenges in dense urban centres. This “Smart Fusion Pole” combines LED street lighting with mobile connectivity. Integrated antennas are concealed and can support services from multiple mobile operators on a single pole. American Tower says the design is 5G and IoT ready.

The City of Huntington Beach, California will be the first to deploy this street pole from American Tower, which has an agreement with the city for exclusive access to 200 smart pole locations. It is a start.

Although we do not know the financial terms of such an agreement, cities will soon realize that the cost of upgrading their street infrastructure in an aesthetically pleasing fashion, in this case street lights, can be paid for by the mobile industry. If the public accepts it, we could soon see thousands of such street poles even in a fairly small and lightly populated (by world standards) city such as Huntington Beach (population 200,000).

So let’s say a tower operator has 5,000 fibre-connected street poles equipped for 5G in Huntington Beach. How much can they charge Sprint or Verizon or AT&T for monthly rent? And what impact will this have on the OPEX budget of mobile operators? Will 5G networks be more costly to operate and maintain than 4G?

Expansion in Mexico

In November, American Tower American Tower acquired a subsidiary of KIO Networks that controls more than 50,000 concrete poles and approximately 2,100 route miles of fiber. The purchase price was $500 million in cash. Most of these facilities are located in dense urban areas. Mexico’s population tends to be more urban than rural.

KIO Networks is one of the major data center operators in Mexico. The company is owned by Maria Asuncion Aramburuzabala, whose family holds investments in many industrial sectors of the country.



Mexico’s Red Compartida project

Mexico’s Red Compartida (shared network) project is a private-public initiative that aimed to break-up the dominance of America Movil by providing a shared infrastructure that would allow competition in mobile services to grow. Red Compartida is sometimes described as the largest construction of a new public access network in the world, although it is eclipsed by the FirstNet emergency response project in the U.S. The primary contractor for the project is ALTÁN Redes.

Key facts of the initiative include:

•   Red Compartida will only offer wholesale mobile services.

•   Red Compartida will build a new national network covering at least 92.2% of the population.

•   Red Compartida's largest investor at 33% is Marapendi Holding BV, an indirect subsidiary of North Haven Infrastructure Partners II, an infrastructure fund with a value-add strategy to invest in OECD countries around the world, managed by Morgan Stanley Infrastructure; Caisse de dépôt et placement du Québec(CDPQ), one of North America's largest pension fund manager holds a 12.68% share; Mr. Miguel S. Escobedo holds a 9.35% share; and Mr. Eugenio Galdón, Chairman of Multitel, holds a 3.34% share.

•   Axtel and Megacable also hold a stake in ALTÁN Redes through a series of non-voting shares and without involvement in management; each has a participation of 4.01%.

•   In March, ALTÁN Redes selected Huawei and Nokia as turn-key technology providers for Red Compartida, a pure IP + LTE network.

•   Huawei technology will be used for central and southern Mexico (telecommunications regions 6 to 9), as well as providing the backbone.

•   Nokia's technology will be rolled out in the northern part of the country (regions 1 to 5). Nokia will also supply the network Core, which includes the Network Operation Center (NOC) and Security Operation Center (SOC).

As of 30-January-2018, ALTÁN Redes confirmed that the project was on target to begin operations with 30 percent coverage of Mexico’s population by 31-March-2018.

Presumably, American Tower’s newly acquired facilities will play some role, as that is the basis of the acquisition, but it remains to be seen how the economics of Red Compartida will ultimately play out. The key question ultimately is if smaller competitors will be able to challenge America Movil, and if AT&T Mexico will be able to participate in Red Compartida, and if so, to what extent it does so.

One interesting observation is the presence of Huawei as a principal vendor for Red Compartida – could that be an obstacle for AT&T Mexico?

NTT DOCOMO picks Ericsson’s virtual infrastructure manager

The tower companies will let us know when 5G rollouts get real

Network densification is a key premise of 5G architecture. Once the rollouts of 5G networks begin in earnest, we should expect to see many more cell sites in urban areas across the world. How many more? That remains to see, but the count of small cells could be 10x of the number of macro base stations common in the 3G/4G era – or maybe even higher than that. Each one of these small cells will need a physical location, which must be purchased or leased from a property owner. It requires permits and authorization from municipal authorities. It must have electrical power, and it must have the backhaul capacity to support multigigabit services – this implies fibre connectivity, although some schemes for meshed wireless backhaul are under consideration as well.

One way to measure the progress of 5G rollouts will be to keep an eye on the companies that actually will handle the deployment of physical equipment on the streets. Once we see the independent tower operators report increased rents do the deployment of massive MIMO antennas or the provisioning of new fibre contracts, then we will know the game has really begun.

Building and managing the physical infrastructure is a headache, especially when there are tens of thousands of sites dispersed across thousands of municipal jurisdictions. For this reason, mobile operators have moved quickly to exit this tricky business. In some countries, they have formed networking infrastructure sharing alliances with their rivals. In other countries, they have spun-out their cell site infrastructure into new companies. In the U.S. market, they have sold their tower operations either to Crown Castle or American Tower.

American Tower, which operates approximately 149,000 communications sites, including approximately 40,000 towers in the United States and more than 108,000 towers internationally, prides itself on being one of the largest global real estate investment trusts (REITs). In addition to the towers (masts) mentioned above, its portfolio also includes more than 800 Distributed Antenna Systems (DAS) in malls, casinos, and other indoor/outdoor venues. The Boston-based company, which was founded in 1995, has a simple missions statement – “to be the premier wireless infrastructure provider” – even if it never becomes recognized as a household name by the billions of consumers with smartphones in their hands right now.

In the United States, there are a number of requirements for a company to be considered a REIT, including that the majority of income must be generated by rents or leases rather than services. A different tax methodology can make this form of business organization more appealing than ordinary corporate structures, but there are requirements that may restrict the company’s business activities and strategic manoeuvres. For instance, REITs typically must distribute 90 percent of taxable income to shareholders, rather than using it for other purposes. The structure typically is modeled after mutual funds.  Additionally, REITs must invest at least 75 percent of its total assets in assets, which could restrict the capital investments that the company might make in network equipment.

As of press time, we are awaiting the publication of the company’s financial results for Q4 2017, but American Tower’s recent performance has been good --18 consecutive quarters of double-digit growth in terms of its adjusted EBITDA. Revenue per site is on the rise and with the exception of occasional consolidation of its mobile network customers – which is a major and perennial threat to its business, the general trend is upward and forward. In this era of exploding demand for mobile data, it is a sure bet that mobile operators will be needing more towers and more bandwidth at those towers, than ever before.

In the United States, over the past few quarters, American Tower has experienced organic tenant billings growth at a pace of over 6 percent. The company also sees solid business growth across its diverse international footprint.  American Tower is pursuing a capital allocation strategy that includes stock buybacks, dividends, and acquisitions.

Big breakaway growth opportunities include multi-year network deployments with FirstNet, the first responders' network in the U.S., and Red Compartida, the shared network infrastructure project in Mexico, along with the coming 5G upgrade cycle.

The market is waiting to see financial guidance for how 5G will impact future revenue.
American Tower’s property revenue breaks down as follows geographically.

U.S. 55%
Latin America 18%
Asia                 18%
EMEA 10%

As of June 2017, it’s major customers include the big four U.S. mobile operators

AT&T   15%
Verizon 16%
Sprint             9%
T-Mobile         8%

Corning's RocketRibbon cable packs 3,456 fibers

Corning unveiled a new "RocketRibbon" extreme-density fiber cable for data center and carrier environments.

RocketRibbon cables deliver up to 3,456 fibers in the same diameter as existing central and stranded tube cables. Corning is using a proprietary manufacturing process to create as many as 12 individually protected sub-units, each with 288 closely packed fibers. An extruded color-coded jacket protects and identifies each bundle and allows for direct and easy routing to splice trays, without the need for additional materials, ribboning processes, or furcation kits.

Corning said its new RocketRibbon cable allows operators to quickly install more capacity in the same duct space to accommodate increased bandwidth demand.

“Corning’s industry leadership and unique co-innovation approach mean our customers come to us to help solve their most important problems. RocketRibbon extreme-density cable demonstrates how we work hand-in-hand with our customers, listening to their challenges. In this case, we developed an entirely new system of ribbon protection and sub-units that provide our customers with easier, faster cable access for ribbon identification and splicing,” said Bernhard Deutsch, division vice president and general manager, Corning Optical Fiber and Cable.

Reliance JIO and Cisco collaborate on Multi-Access Edge Computing

Cisco and Reliance Jio are collaborating in multi-access edge computing. The companies are developing a use case to optimize and enhance video experience over the network by building a mobile content delivery network (CDN). In this concept, the CDN is integrated into the mobile LTE network with edge caches in close proximity to the mobile users.

The idea with a mobile CDN is for the mobile operator to deliver content via edge cloudlets to provide a better user experience with lower latency and higher performance.

Cisco said its mobile CDN work with Reliance Jio uses a combination of IP address management techniques based on the mobile core, requiring tight integration between edge cache, mid-tier cache, and the traffic router in the Cisco Open Media Distribution system. The mobile core and the Cisco Open Media Distribution are combined into one system level solution for the CDN embedded in the mobile network.

To solve the problem of user plane selection, the system uses Control/User Plane Separation (CUPS) as defined in 3GPP R14.

Cisco and Reliance Jio also solved the issue of assigning a geographically appropriate IP address to the mobile device and the issue of handover resiliency in the face of IP address changes on the client side and the CDN cache site without change or disturbance to the current services.

A version of the GX66473, the GX66474, operates with two standard supply voltages, making it suitable for the CFP2 form factor modules.

IDT will demonstrate the new device at this week's OFC in San Diego.

ZTE enhances core router with Bit Indexed Explicit Replication

ZTE has enhanced its ZXR10 T8000 core router with the addition of Bit Indexed Explicit Replication (BIER) technology -- an industry first according to the company, and useful for balancing SDN backbone network traffic.

ZTE describes BIER as a simplified multicast packet forwarding technology that does not require complex multicast protocols and multicast forwarding tables. It can efficiently distribute multicast packets only by switching the messages of the multicast senders and receivers instead of maintaining multicast flow status, which perfectly fits the philosophy of SDN centralized control.

The ZXR10 T8000 router supports multiple northbound interfaces. The company's software enables traffic optimization and scheduling based on policies, which can help achieve load balancing, reduce the link congestion ratio, delay network expansion, and improve user experiences.

Netsparker raises $40 million for its web security software

Soyuz rocket carries four O3b MEO satellites to orbit

A Soyuz rocket launched by Arianespace from the Guiana Space Center successfully carried four O3b satellites into Medium Earth Orbit (MEO).

The new Ka-band satellites will join SES’s existing constellation of 12 MEO satellites, orbiting at approximately 8,000 km from Earth – four times closer to the planet than geostationary (GEO) satellites. Thales Alenia Space built the satellites.

“We are very excited to have four more O3b satellites in orbit, and we look forward to them joining the constellation in May and serving our customers around the globe. The demand for high performance bandwidth and networks continues to grow and, as the only successful non-geostationary broadband system, we need these new satellites to fulfil demand across a wide range of verticals and applications. From connecting underserved communities and meaningfully transforming lives through improved broadband access, to delivering state of the art satellite-enabled network services to ships, planes and government platforms, our O3b fleet offers unique and differentiated performance and is driving our customers’ businesses forward,” stated Steve Collar, CEO at SES Networks. Another four O3b satellites are scheduled to launch in H1 2019, also on Soyuz rockets.
