FAA letter invalidating the certification of lighting systems with non-OEM replacement parts

August 17, 2018

On June 27, 2018, the FAA rescinded a letter dated Nov. 22, 2005 that allowed the used of non-OEM parts for certified lighting systems.

This effectively invalidates any certified lighting systems that uses non-OEM parts.

This FAA action DOES NOT affect any Unimar lighting system where Unimar has supplied the replacement parts.

IoT Done Right™, Managed Solutions By Unimar

March 19, 2018

Internet of Things (IoT)

A lot is being said about IoT.  There are a great many resources out there talking about it, and far more vendors selling pieces of it.  That’s the issue – pieces and confusion.

What a challenge it can be to find an optimized solution that meets your specific needs.

Sure, there are big names out there that are “in” IoT, many fortune 500 Companies are there.  You may be tempted to contact one of them.  Guess what?  They will put you in touch with a software developer, who may put you in touch with a hardware guy, who may put you in touch with a Gateway supplier, who will put you in touch with a carrier…….next thing you know you are overwhelmed with the technical lingo and are feeling  “like an IdioT of IoT”.

Worse yet, the solution you may end up with will take months to implement, is a hodgepodge of expensive hardware, onerous software and monthly fees that will eat you alive. Worse yet, it ‘almost’ does what you really want.

Next thing you know you are adding staff to manage it all, paying not only for development but monthly fees to the cloud provider, the cellular carrier, an ISP and managing multiple suppliers.   Wait until one of them has a ‘required firmware update’ – now you are in for some stress…

You need a ‘hands off’ managed solution, you need it fast, you need it cheap – but most importantly, you need IoT Done Right™.

Contact us, we provide IoT done Right™, and take the IdioT out of IoT.

FCC Encourages Tall Tower Owners to Snuff L-810, Steady-Burning Lights

January 9, 2018

The FCC is encouraging owners of towers taller than 350 ft. AGL to take advantage of lighting changes passed by the FAA, to both help save migratory birds and reduce operations costs.

“Lighting changes on towers taller than 350 ft. AGL involve extinguishing L-810, non-flashing, side-markers and do not require any additional cost or fees,” states a message from the FCC to tall tower owners. “Lighting changes on towers 150-350 ft. AGL involve reprogramming non-flashing, LED, side-markers to flash synchronously with flashing L-864 lights.”

“New tower lighting schemes should now follow the revised guidance, and operators of towers with the old lighting system should submit plans explaining how and when they will transition to the new standards,” according to the FAA in 2016.

Testing conducted by the FAA determined that birds are not attracted to the flashing lights of towers but are attracted to the non-flashing, steady-burning L-810, side-marker lights. In response to these findings, the FAA determined that extinguishing the L-810, non-flashing lights on towers taller than 350 ft. AGL and reprogramming L-810 lights on towers 150-350 ft. AGL, is safe for aviation. In December 2015, the FAA changed its red tower lighting recommendations to systems without non-flashing L-810 lights and said that minimizes bird collisions by as much as 70 percent and on towers taller than 350 ft. AGL, reduces tower construction, maintenance, and energy costs.

Extinguishing the non-flashing lights on existing towers taller than 350 ft. AGL can be completed without climbing the structures, according to the FCC. Similarly, the elimination of continuously burning security lights on the buildings under towers will minimize bird attraction to the site. If security lighting is required, the FCC advises using motion sensor triggered security lighting under your tower.

Here’s how to file the necessary paperwork to process the change. A “lighting deviation” can be used to extinguish or eliminate L-810 steady-burning side lights from an existing registered tower taller than 350 ft. AGL and to reprogram L-810 steady-burning side lights to flash on registered towers 150-350 ft. AGL.

What to do:

  1. File a Marking and Lighting study electronically with the FAA (https://oeaaa.faa.gov/oeaaa/external/portal.jsp) requesting the elimination or omission of steady-burning lights (L-810) or requesting that steady-burning lights flash with Form 7460-1, Notice of Proposed Construction or Alteration. Designate structure type: “Deviation from Red Obstruction Light Standards.”
  2. Once the FAA has approved the request and assigned a FAA Study Number, file Form 854 with the FCC via the Antenna Registration System (ASR). Please select “MD – Modification” and choose the appropriate FAA Lighting Style. The FCC typically will approve the application and modify the registration within 24 hours.
  3. Once the lighting change for a tower has been granted by the FCC via ASR, the L-810 steady-burning side lights can be extinguished on towers taller than 350 ft. AGL and reprogrammed to flash in concert with L-864 lights on towers 150-350 ft. AGL. Extinguishing L-810 lights and reprogramming lights are typically accomplished in the tower transmission building and do not ordinarily require climbing the tower. Per the FAA requirements, flashing red lights should flash at 30 FPM (+/- 3 FPM).

FCC Frowns on Tower Lights Being Out 7-plus Months

November 16, 2017

Tower lights not working at a broadcast station in Arkansas got the FCC’s attention. The Enforcement Bureau sent a Notice of Violation to Bobby Caldwell owner of East Arkansas Broadcasters, Inc.

Checking its Notice to Airmen (NOTAM) database, officials find the broadcaster has received four NOTAMs since February. The latest will expire at the end of December and the agency says it has not received any indication saying the lights have been repaired. The tower is (Registration 1038728) in Jonesboro, AR, according to the FCC’s ASR database.

“Replacing or repairing of lights, automatic indicators or automatic control or alarm systems shall be accomplished as soon as practicable,” writes Ronald Ramage, regional director of the bureau in the notice. Unless reasons provided by East Arkansas Broadcasters, Inc., prove otherwise, a duration greater than seven months is beyond the bounds of “as soon as practicable.”

The broadcaster must respond within 20 days, explaining how the violations occurred, actions taken to correct them and prevent the tower lights from going out again. The response will help the agency determine what, if any, enforcement action is required to ensure compliance.

Widespread Power Outages in Puerto Rico, VI Continue to Hamper Tower Sites

September 26, 2017

As widespread power outages continue in Puerto Rico, about 92.5 percent of cell tower sites in the U.S. territory aren’t working, down slightly from 95.6 percent on Saturday, according to data submitted by communications providers to the FCC’s Disaster Information Reporting System (DIRS). Indeed, it appears there has been “minimal improvement to the communications networks in Puerto Rico since the Hurricane departed,” according to the agency. DIRS is now activated for all counties in Puerto Rico and the U.S. Virgin Islands (USVI).
PR Cell sites out of service map

Of the 78 counties in Puerto Rico, 37 (down from 48 on Saturday) have 100 percent of.their cell sites out of service, according to Sunday morning’s data. More than 75 percent of the cell tower sites are not operational in all counties.

In the USVI, 61.3 percent of cell sites are not operational, down from 66 percent on Saturday.

The two emergency call centers in Puerto Rico appear to be working normally, according to the primary service provider. In the USVI, the St. Croix 911 Call Center has been reported as completely down. FEMA has reported significant damage to the building. The St. Thomas 911 Call Center is unable to retrieve certain location information for wireless and VoIP callers.

AT&T sent planes with restoration equipment, (including generators) personnel and humanitarian supplies to Puerto Rico and the USVI over the weekend; additional flights are slated for the next few days, a carrier spokesman told Inside Towers.

“We are coordinating with local and federal authorities to support recovery efforts,” said spokesman Jeffrey Kobs. “We are working to keep our customers connected and to restore services to areas where storm damage, power outages, and flooding have interrupted service.”

In the USVI, AT&T set-up a portable cell-site near the airport in St. Thomas, and has restored some power there and on other islands. The carrier plans to bring in additional resources.

AT&T is automatically issuing credits and waiving additional fees to give unlimited data, talk, and texts to AT&T wireless customers and unlimited talk and texts to AT&T PREPAID customers in Puerto Rico and the USVI through September 29. The company is also extending payment dates for impacted AT&T PREPAID customers with voice and text service through September 29.

Sprint extended its waived text, call and data overage fees for Sprint, BoostMobile and Virgin Mobile customers in Puerto Rico and the USVI through September 29. Fees will be proactively waived during the specified timeframe. “As authorities and our teams on the ground assess the situation,” stated Sprint CEO Marcelo Claure.
