Come See Us at IWCE 2014!

This year, we'll be showing off new products and talking about a great year ahead at IWCE. Come see us at booth #9037 to see the new 100 Foot Articulated Lattice Tower (featured below) and more. And don't miss our sessions at the conference, Hardening Sites for LTE Migration and Tower Management from Top to Bottom.


OSHA Calls on Industry to Eliminate Climber Deaths

“OSHA has found that a high proportion of these incidents occurred because of a lack of fall protection: either employers are not providing appropriate fall protection to employees, or they are not ensuring that their employees use fall protection properly,” wrote David Michaels, assistant secretary of labor for occupational safety and health. “It is imperative that the cell tower industry take steps immediately to address this pressing issue: no worker should risk death for a paycheck.”

Mission Critical

FirstNet Approves Program Roadmap

The roadmap includes several milestones to be completed in the coming year including initiating public notice and comment on certain procedures. FirstNet will release procurement process plans and proposal requirements for requests for proposals (RFPs) for a comprehensive network and network equipment and services. The staff will also deliver proposal requirements for National Environmental Policy Act (NEPA) resources and spectrum relocation. The staff also expects to begin formal state consultations.

Product Focus – 100 Foot Articulated Lattice Tower

The new 100-foot Articulated Lattice Platform Tower combines the easy set up and antenna placement of Pepro’s monopole towers with a lattice design that offers far greater height and support for multiple antennas or dishes.

Because the tower features Pepro’s patented articulated design, it can be deployed section-by-section rather than telescoped to its full height. That means antennas can be attached to any section before the tower is raised, or the tower can be lowered easily with the antennas attached, adjusted as needed and restored to full height. At no point do technicians need to climb the tower. Depending on the site location and configuration, the Pepro Lattice Platform Tower will also save customers 30 to 40 percent of the cost versus standard towers.

“Towers are going up at a brisk pace, and that means increased risk and high demand for technicians,” said Kelly Lander, president of Pepro LLC. “Our unique design lets technicians do their work faster and more safely than possible with traditional towers, while providing the height needed for tree canopy clearance, extended range and placement of several antennas or dishes.”

The 100-Foot Lattice Tower has a footprint of 30 × 34 feet, weighs 22,390 lbs. and complies with the TIA-222-G standard. It comes with 12 leveling jacks and 24 Ufer ground pads. It is intended for use with Pepro’s stationary enclosures measuring 8 × 8 feet to 8 × 16 feet.

Pepro's platform tower design reduces installation time, liability, equipment downtime, and cost while increasing safety. A total site, tower and shelter, can be operational within 2 days of installation. Pepro platform towers are designed to eliminate concerns and simplify operations.

Pepro Helps Keep the US Forest Service Connected

The US Forest Service is one of our largest customer to date and has employed a number of our enclosures. Their use has spanned the product line, including the stationary remote re-deployable units and antenna mast products.

Prior to deploying Pepro Engineered Enclosures, the Forest Service had used a number of different solutions, most involving the modification of readily available surplus materials. In addition, the locations of these facilities are often on very remote mountaintops, not typically accessible by normal vehicle. As with many remote areas, care must also be exercised not to disturb the environment, archeological heritage, or wildlife.

To address these problems, the Forest Service and their consultant chose the Pepro Engineered Enclosure system, including the antenna mast. These enclosures could be flown in by helicopter, set up with a minimum of personnel, and left alone to protect the digital equipment enclosed inside with a minimum of maintenance. This was a key issue because of the expense in transporting personnel to the site for set-up and any subsequent maintenance or repair visits. The masts are also able to withstand the high winds at the sites, many of which are above 6000’ in elevation. All of this was done without the need for environmental or other site studies because of the minimal footprint of the enclosures. Pepro was the only company able to provide a simple, relatively low cost, efficient, durable, and quickly deployed solution that also provided a maximum amount of protection against electrical and other physical threats to the enclosed equipment.

Hardening Sites Means Preparing for the Worst Case Scenario

As the push for a dedicated Public Safety Broadband Network draws closer to reality, it should be the goal of key decision makers and stakeholders, to ensure the network is built to the same rigorous standards for site hardening that have been utilized by the public safety community to build existing mission critical LMR networks.

A key component of FirstNet’s plan for an affordable LTE network is to develop public/private partnerships which would include commercial carriers. A review of recent major emergency events, such as Hurricane Sandy, the earthquake in Washington DC, the derecho winds in July 2012, (which caused destruction along a 700 mile path in the Midwest and Mid Atlantic), highlights the weaknesses of commercial carriers during the most critical times. Whether the weakness is due to a lack of backup power, failure of backup power, congestion of the network, or loss of equipment due to power surges, it dramatically illustrates the distinct difference between a business model for communications and a mission critical/public safety model.

Determining the hardening requirements for a Public Safety grade, “always on” network is not a one-size-fits-all/most solution. The process starts with an accurate assessment of all the potential threats, both natural and man-made. In public safety terms, this means determining the “worst case scenario” for both and then establishing that as the minimum hardening requirement. In the gulf and on the east coast where the threat of hurricanes is an annual threat, the wind load requirements for towers and shelters should meet that expectation. In areas where flooding is a threat, back-up power should be elevated to safeguard against damage. Some threats are fairly predictable by region/season, such as wind, lightning, heat, etc. Other natural events are not as predictable but are a potential threat, depending on geographic location, such as hurricanes, tornadoes, wildfires and earthquakes.

Man-made threats include but are not limited to industrial accidents, fires, vandalism, active shooter or hostage events, and terrorist attacks. Man-made threats don’t have to be major events either, they can be interference caused by a nearby industrial complex, or a radio station. Training first responders to lean on systems that can fail or degrade in predictable situations will compromise their performance when they need to be at their best.

First responders should never have to ask "can you hear me now?" The commercial networks are only as useful to public safety communications as their performance in a worst case scenario. Assets and systems, no matter how useful in optimal conditions, should not be introduced unless we know we can rely on them in a crisis.
