Chairman Pai Praises Tower Industry Hurricane Recovery Efforts

By J. Sharpe Smith

Cell towers were more resilient during Hurricane Harvey in South Texas than in previous storms, FCC Chairman Ajit Pai told an audience during his keynote at the Mobile World Congress Americas today in San Francisco. The news from Florida, however was not quite as upbeat with the affected disaster area losing service from more than 27 percent of the cell towers.

“About 5 percent of cell sites were down [in South Texas], as opposed to 25 percent for Hurricane Sandy,” Pai said. “That wireless connectivity was literally a lifeline for many.”

More than 96,000 calls were made to Houston’s main 911 emergency response center, many of which were from wireless phones.

“Many of the more than 11,000 people rescued by the Coast Guard were found because of wireless calls,” Pai said. “That includes one 14-year-old girl who was saved after telling Siri, ‘Call the Coast Guard.’” Smartphones were used to access social media platforms such as Facebook and Twitter to summon help and keep tabs on loved ones.

Pai applauded the “heroic efforts to quickly restore communications” of the technicians working to bring Houston and South Texas back online and on the air.

“When the rain was still coming down and the water was still rising, technicians braved the elements to fix service disruptions as quickly as possible,” Pai said.

A Tale of Two Hurricanes

Compared with Harvey, Hurricane Irma affected a much wider area striking with Category 4-force winds, as it steamed up the Gulf Coast of the state. Of the more than 14,500 cell towers located in the disaster area, nearly 4,000 cell towers had lost service as of Sept. 11.

Puerto Rico and the U.S. Virgin Islands saw improvement on Monday with 21.5 of affected towers out of service, compare with nearly 27 percent on Sunday.

“Now, reports so far indicate that communications services in the path of Hurricane Irma have not fared as well due to staggering winds,” Pai said. “But we’re grateful for the hard work people are doing to keep wireless networks up and running for as many people as possible.”

Chinese Drone Maker Dropped by U.S. Army Over Cybersecurity Worries

By J. Sharpe Smith

There is controversy brewing in the drone world. The U.S. Army has dropped the use of all UAV products made by Chinese manufacture DJI Technology because of cybersecurity concerns, in a memo released earlier this month.

DJI, whose products are the most widely used commercial, off-the-shelf drones used by the Army, was accused of caching data obtained by the drones and sending them back to DJI’s computer servers over the internet.

The army will cease the use of any system that employs DJI electrical components or software including, flight computers, cameras, radios, batteries, speed controllers, GPS units and handheld control stations.

Phil Larsen, RDF Wireless, whose company only uses American-made drone products, said the  drone industry will not be adversely affected by the news.

“Drones aren’t going anywhere,” Larsen said. “The industry will just continue to grow, and now with DJI under scrutiny American companies will get a chance in the arena.”

This week, Reuters reported that DJI is improving the data security of its products in response the U.S. Army ban. A system is being developed that automatically disconnects from the internet during flight. This would protect any flight logs, photos or videos collected by the drones.

 

Edge Computing Coming to Tower Sites; Crown Castle Buys In

June 22, 2017

Senior Editor, AGL eDigest

Remember when we all thought that 4G LTE technology with its antenna-mounted amplifiers spelled the doom of size-able equipment enclosures at the base of cell towers? Well, think again. Project Volutus was unveiled yesterday by a company called Vapor IO, which wants to build a giant network of distributed edge data centers at the bases of thousands of cell towers, which will be directly connect to wireless networks.

Removing all doubt that this is a big deal for towers, Crown Castle International, the nation’s largest provider of shared wireless infrastructure, has made a minority investment in Vapor IO to accelerate the project’s development and deployment.

Making Towers a key to 5G

Edge computing has always been part of the 5G game plan. No matter the bandwidth or the protocol, if a smart phone or robot or connected car cannot quickly access the Cloud for the needed data it will not perform at the needed latency goals of 5G. But now a company, Vapor IO, has stepped up with technology that pushes access to the cloud to the edge of the network.

“There’s a new class of applications—including IoT, virtual reality, autonomous and connected vehicles, and smart cities—where the existing model of large, centralized datacenters just won’t work,” Vapor IO said. “These applications need compute and storage to be located more closely to the device or application. The round trip back to a centralized data center takes too long and the amount of data that needs to be transferred is too large.”

Project Volutus is a collocation and “data center as a platform” service, which is a fully-managed micro data center at the base of the cell tower, literally at the true edge of the wireless network. It combines Vapor IO’s hardware and software with the network of cell towers and dense metro fiber to build and operate distributed edge data centers in major metropolitan locations.

“Project Volutus combines edge co-location with remote operations, intelligent cross-connects to wireless networks, and direct fiber routes to regional data centers and peering interconnects,” the Vapor IO said. “It provides point-to-point, multi-point and mesh tower-to-tower connections, bypassing the multi-hop high-latency backhaul of the legacy wireless networks and delivering low millisecond round trips.

Project Volutus uses Vapor IO’s “Vapor Chamber,” an energy-efficient rack and enclosure system designed for edge environments. Ecosystem partner Intel is supplying its FlexRAN and Multi-access Edge Compute (MEC) software libraries to provide an agile virtualized radio access network (vRAN) foundation platform for Project Volutus.

“By collaborating with wireless carriers and telecom equipment manufacturers running vRAN and MEC in Vapor Edge Computing locations, we can bring the network closer to the mobile user,” Caroline Chan, VP of 5G Infrastructure Division of Intel.

Project Volutus will be available for early access in Q3 and multi-city rollouts are targeted to begin later in the year.

Future Estate Communications Solutions 

The next generation of wireless networks will drive the need for all different types of communications assets: from macrocells, small cells and DAS to fiber optics, centralized RAN (C-RAN) and data centers. In a recent interview, officials from Digital Bridge said they are intent on amassing a variety of assets to serve all carriers’ needs, as well as Cloud and content players.  Wholly-owned subsidiary Vertical Bridge has accumulated assets in buildings, rooftops, utility attachments and macrocells all as part of a turnkey real estate communications solution.

“I take it personally when people call us a tower company. We are no longer a tower company,” Bernard Borghei, senior VP, operations and co-founder, said. “We are a real estate solution provider. We have all these different types of assets to meet the demands of today’s advanced technology leading into 5G and beyond.”

Even the real estate under suburban towers may come in handy as locations for micro data centers as wireless providers push their data centers closer to the edge of the network, according to Alex Gellman, Vertical Bridge CEO and co-founder.  “If C-RAN is to be located at specific sites, we look at marketing the land under our sites for a C-RAN hub,” he said.

New Regulations Affect Towers Less than 200 Feet High

August 30, 2016 —

The newly enacted FAA Extension, Safety & Security Act may require tower owners to mark structures less than 200 feet high above ground level as aviation navigation hazards.

By Jeff Jacobs

Do you own or service a tower or structure that stands less than 200 feet high above ground level (AGL)?

Do you plan on constructing one in the near future?

The lighting requirements for these towers may increase with the U.S. House of Representatives bill HR 636 that the president signed on July 15, 2016. The bill, “FAA Extension, Safety and Security Act of 2016,” was the vehicle used to reauthorize funding for the Federal Aviation Administration for fiscal year 2017, which starts on Oct. 1, 2016. Previous to the passage of the bill, the FAA did not typically consider towers less than 200 feet AGL to be hazardous to air navigation, and thus did not require such towers to be equipped with obstruction lighting equipment.

Congress passed HR 636 to extend the FAA’s operations for another 12 months through September 2017. Its three main sections are “Title I — FAA Extension,” “Title II — Aviation Safety Critical Reforms” and “Title III — Aviation Security. “ Within “Title II Subtitle A – Safety,” Section 2110 details that the FAA must enact new tower marking guidelines within one year of the enactment of the HR 636 for “covered towers.” These guidelines require that a covered tower be clearly marked per FCC advisory circular AC 70/7460/1L, dated Dec. 4, 2015.

The real question becomes: What is a covered tower? There are guyed towers and self-support towers, but what is a covered tower? Here is the definition of a covered tower per HR 636, Section 2110.d.1.A:

i. It is self-supporting or supported by guy wires and ground anchors.

ii. It is 10 feet or less in diameter at the aboveground base, excluding the concrete footing.

iii. The highest point of the structure is at least 50 feet above ground level.

iv. The highest point of the structure is not more than 200 feet above ground level.

v. It has accessory facilities on which an antenna, sensor, camera, meteorological instrument or other equipment is mounted.

vi. It is located outside the boundaries of an incorporated city or town, or on land that is undeveloped or used for agricultural purposes.

With all that, the act has some exclusions. The provisions of the act do not apply if the tower is adjacent to a house, barn, electric utility station or other building; if it is within the curtilage of a farmstead; if it supports electric utility transmission or distribution lines; if it is a wind-powered electrical generator with a rotor blade radius that exceeds 6 feet: or if it is a street light erected or maintained by a federal, state, local or tribal entity.

With the hundreds of thousands of towers dotting the landscape of America, there will be an increase in the number of affected towers that will need to be reviewed for lighting requirements to provide air navigation safety to the flying public. This is not intended for the safety of large commercial airlines, but more for the small plane pilots (crop dusters), medevac helicopters and other low-flying aircraft. Even with the exclusions, there will be thousands of covered towers that the FAA will need to have cataloged and reviewed in order to determine whether they are hazardous to air navigation.

What does this mean for tower owners? Because guidelines will not be ready for review or publication until sometime next year, the tower owners should become familiar with the FAA AC 70/7460-1L to understand the requirements for structures 200 feet AGL or less. These types of towers are typically lit with red lights for nighttime marking and painted with white and orange bands for daytime marking. AC 70/7460-1L limits the use of medium-intensity white lighting to no less than 200 feet AGL. With the good news of possibly only needing red lights comes the bad news of the requirement to apply paint.
