Edge Computing Could Help Both Carriers, Tower Owners

By J. Sharpe Smith

Edge computing is becoming part of the network conversation as more companies go public with their solutions for wireless communications. Placing data center infrastructure, i.e. content, at the edge of the network will give immediate access to the internet to billions of mobile devices, such as smartphones, medical devices, industrial controls and IoT sensors.

But that vision of the future goes out a few years.

What carriers need right now is a way to cut their backhaul costs which have risen because of the increased traffic caused by unlimited data plans, Greg Pettine, founder and EVP of business development, said in a phone interview with AGL eDigest.

“The [carriers] know that if they can get some of the content out beyond their core data centers out to the wireless edge, they can significantly maintain their operating expenses regarding fiber to the tower. That’s big,” Pettine said.

Also important to today’s carrier operations is the performance of the network, which can be negatively affected by traffic congestion. “The [carriers] have admitted to throttling back users of certain applications, such as YouTube, Facebook, Netflix and Amazon,” Pettine said. “This results in churn, which they don’t want to happen.”

EdgeMicro’s answer to the traffic congestion problem is to locate the data from these websites in a micro datacenter positioned at the cell site or a central office or a mobile telephone switching office. Then, when a data request comes into the tower, the system redirects it to the micro datacenter to get the data, instead of backhauling it to the regional data center.

The organizations may take advantage of storing data in a micro datacenter because they are the ones driving the most content across the internet. Those companies including Facebook with Facebook Live; Instagram; Google with YouTube, Akamai Technologies, which is used by the ad networks; Amazon and Netflix.

Data traffic in EdgeMicro’s network-neutral micro data centers is managed by a technology known as Tower Traffic Xchange (TTX), which is a Local IPAccess (LIPA) solution that combines all the necessary LTE network components into a single, low-power, collocated appliance.

EdgeMicro gave a preview of its TTX and micro data center at the Competitive Carriers Association’s (CCA) Annual Convention earlier this year in Fort Worth.

The company’s medium-term plan is to deploy at 500 tower sites in the next five years. First, 30 micro datacenters will be deployed at busy multi-tenant towers that serve 100,000 people in the next 18 months in tier-two cities, which don’t have a lot of backhaul, content or ISP peering.

“That will provide us with the data to proliferate our micro datacenters,” Pettine said. “EdgeMicro’s prefabricated micro data centers will be deployed at ultimately thousands of cell towers globally.”

EdgeMicro’s collocation model is based on an 8-foot by 20-foot container with six racks. A quarter rack would be sold to each content provider, which works out to 24 customers in each container.

“We are in various stages with the [carriers], introducing it into their labs for testing. Ultimately, they need to start field test the acquisition of data,” Pettine said.

Micro Datacenters: Good for Towers?

What is in it for tower companies? Providing micro datacenters will make towers stickier, reducing carrier churn. Tower companies would make good strategic partners and could fund the effort as an alternative cash flow.

“Tower companies get increased rent and have the potentially to be strategically aligned in bringing in innovative cash flow,” Pettine said, “But they don’t know anything about data centers and that is where we come in. We understand the collocation model from a datacenter perspective: the cost-to-build and opex.”

Tower companies have already shown an interest in micro datacenters. For example, Crown  Castle International is a minor investor in Vapor IO, whose Project Volutus enables cloud providers, wireless carriers and web-scale companies to deliver cloud-based edge computing applications via a network of micro data centers deployed at the base of cell tower sites.

“The cloud of the future will extend past today’s large, centralized data centers. The next generation cloud will follow your car. It will follow your phone. It will follow your sensors. It will be distributed and data driven and everywhere,” Alan Bock, vice president of corporate development & strategy, Crown Castle.

Vertical Bridge announced in late September that it has partnered with its sister company DataBank to host edge computing at the base of cell towers. Additionally, AT&T has announced it also has micro datacenter plans.

One pundit has claimed that the Cloud is “dead.” While that may be an overstatement, the global market for micro data centers is certainly alive and projected to be $8.47 billion by 2022, according to a report on MarketstoMarkets Research.
