FirstNet deployment should be more than 60% complete by end of year, AT&T exec says

More than 60% of the planned buildout of the FirstNet system will be completed by the end of this year—months ahead of the contracted schedule—with a realistic possibility that even more progress will be made on the nationwide public-safety broadband network (NPSBN), an AT&T executive said yesterday.

Next 9-1-1 Vertical Location Tests Scheduled for July, Call for Interested Vendors

The 9-1-1 Location Technologies Test Bed, an entity established by CTIA, invited vendors of location accuracy technologies to participate in vertical positioning accuracy evaluation — known as Stage-Za — in the 9-1-1 indoor location technologies test bed. This testing round is the next step following the initial Stage-Z tests conducted in 2018.

The vertical location test campaign is scheduled to begin in July 2019.

The test bed independently evaluates the ability of wireless providers and location technology solutions vendors to meet the FCC’s indoor 9-1-1 location accuracy requirements through different technologies, CTIA said. Stage Z focused on emerging indoor technologies that determine the altitude, or Z-axis, of 9-1-1 callers in multistory buildings.

Technology of the Year: FirstNet

Hurricane Florence. The California wildfires. A deadly shooting at a Texas church.

The public emergencies of 2018 also served as a proving ground for FirstNet, the long-awaited wireless network offering dedicated broadband to first responders. The service was dreamed up after the 9/11 terrorist attacks, but only launched in March after years of budget troubles, debates with Congress and a search for private partners.

But in those months, the partnership between the U.S. Department of Commerce’s National Telecommunications and Information Administration (NTIA) and AT&T has proven its potential for boosting the capabilities of first responders across the country, giving them dedicated service and new technology applications that boosters say will bring public safety into the smart cities age.

The Pepro Two-Bay Micro Radio Site

The Two-Bay Micro Radio Site is a compact, self-contained and low profile mobile site designed to fill coverage gaps as well as any other situation where a rapidly deployable solution is needed. It is specifically designed to be LTE and FirstNet ready. The unit is completely self-grounded while in use, requiring no additional time or equipment for safe deployment. It needs no separate foundation and has no impact on the surrounding environment.

The Two Bay Micro Radio Site is a low-profile mobile site, standing less than six feet tall when the integrated articulated tower is lowered for easy mobility. The tower can be quickly and easily raised from the ground with all antennas and equipment already attached. The full system is deployable by one person in as little as 15 minutes. As with all Pepro products, the Two-Bay Micro Radio Site is designed for reliability and durability.

Protecting your equipment from Lightning, EMP, EMI/RFI, and PIM

A Faraday Cage, discovered by Michael Faraday in 1836, is a hollow conductor that cancels out charges in the space inside. The flow of electrons, as induced by the external field, creates a counter-acting field around the cage, and as a result, the volume inside a Faraday Cage sees zero electric field. No matter what electrical forces exist on the outside, an equal and opposite force protects the inside of the cage.

When it comes to protecting sensitive equipment at a radio site, there is no better grounding, but in practice, it pays to be careful in selecting a shelter. Lightning strikes can happen anywhere, and even grounding will not protect your equipment from the magnetic field resulting from a nearby, high-current lightning strike. You need to find shelter designs that have been tested for lightning strikes and proven in the field. Pepro shelters have been tested by Lighting Technologies Incorporated (now part of NTS laboratories) to withstand 87,000 Amps and over 1 million Volts on the tower, equal to the 95th percentile of all lightning strikes. Radios placed inside the shelter maintained a signal throughout and following the test. Further, our shelters have served hundreds of sites around the world with no failure of equipment from electric forces.

The protection predicted by Faraday has been proven out, time and time again by our shelters, and that makes all the difference when first responders are out in a storm, counting on communications to keep them connected and safe.
