In a previous article, we covered mistakes often made during climbs, including lack of a climbing plan, missing signage, insufficient training and certifications, poorly maintained safety gear or missing safety gear, and failure to keep an RF alarm turned on. Now we will address some solutions to tower climbing for improved safety, including technologies that eliminate the need to climb at all. While one of the downsides to the increased use of remote radio heads is that it places more equipment on the tower, emerging technology in test equipment can help. The fiber connection that runs from the top to the base can be lever- aged to maintain the tower from the ground by reading the RF signal transmitted via Common Public Radio Interface (CPRI). The result is safer, more cost effective tower maintenance, plus the ability to perform more regular signal analysis. Another alternative to dangerous climbs is to let a nonhuman make the journey. Increasingly, drones are being utilized for site surveys and equipment checks in hazardous conditions. While drones may not be able to measure and analyze sig- nal strength, they're per- fectly suited for hardware inspections on towers. Equipped with high reso- lution cameras and com- bined with streamlined software that stores and catalogs images, drones can provide insight into the condition of towers and help determine when equipment may need to be repaired or replaced. While technologies continue to provide safe alternatives to tower climbing, towers themselves are also evolving to meet the same challenges. Many sites now utilize hinged, articulating, and self-erecting towers that eliminate the need to climb altogether. These infrastructure-based solu- tions dramatically decrease installation and oper- ational costs by bringing active components down to the contractor's level. After being serviced or swapped, the use of simple machinery returns the tower to its fully erected form with no risk to the maintenance personnel and minimal interruption to the network. Should tower climbs still be necessary, appro- priate safety measures and preparations should be taken to avoid the problems mentioned in our previous article. TESSCO offers a wide assort- ment of climbing safety equipment that meets OSHA and ANSI safety standards, which can be combined into a comprehensive climbing kit that meets every need. Safety harnesses are available Four Steps to Simplifying Your Leased Line Migration Submitted by TESSCO Technologies Replacing leased lines can save you money and improve your efficiency by no longer relying on a third party carrier to respond to issues , but there are many factors to consider when planning a migration. Fortunately, with a well-considered plan and the right partner your transition doesn't need to be complicated. By paying attention to these four steps you can streamline your migration and ensure a seamless cutover. 1. Select the right backhaul transport. Choosing the right option to replace your leased line is crucial and will depend on many aspects of your project, including everything from the type of equipment currently used to the distance and terrain you'll need to traverse to deliver data. By looking forward and con- sidering the obstacles facing your installation now, as well as future factors like the amount of throughput you'll need and the type of data you'll need to transmit, you can future proof your replacement and avoid costly updates the first time. 2. Address site considerations. The physical loca- tion of your lines will influence your project requirements. Consider all your antenna mounting options, determine your power needs and how you're going to deliver the power, and think about environmental factors that could come into play, including extreme weather conditions. By preparing for these potential problems at the outset you can develop a migration that best prepares your network for success. 3. Develop a full bill of materials. Underestimating your material needs can derail a project and cause costly delays, and overestimating means wasted money. By developing a comprehensive bill of mate- rials and utilizing a single source provider like TESSCO you can be sure you have everything you need, when and where you need it. And if you run into any issues you will be able to rely on a single point of contact to resolve them. 11126 McCormick Road Hunt Valley, Maryland USA 21031-1494 Sentera Many sites now utilize hinged, articulating, and self- erecting towers that eliminate the need to climb altogether.
