December 2014 / January 2015 your site with respect to coverage, other factors, such as power and zoning restric- tions, can impact your choices. Once you've determined possible sites, develop the bill of materials required to cover other consid- erations such as grounding, power, weath- erproofing and mounting needs. Each site is unique. Site layout, zoning requirements, prevailing weather condi- tions and other factors may not be the same in every location. Your mounting solution may need to change from site to site. For rooftops, universal and modular mounting options help you configure the solution that fits each site and minimize the variety of equipment your team needs to employ. It is possible that you'll need to reconfigure your communication sites in the future to add capacity and improve coverage or simply to take advantage of a new technology. Universal mounting solutions allow you to change your con- figuration as your network changes without starting from scratch each time.

Visible anten- nas or obvious communication sites on a rooftop may not always be desirable. This issue may be even more problematic with sites such as light poles, kiosks and utility poles. Solutions are available to conceal and disguise your wireless equipment. In addition to addressing aesthetics, these solutions can add environmental protection and security to rooftop, building and pole-mounted sites.

Network and Radio Requirements The challenges associated with evolving networks are not limited to infrastructure concerns. Consumers are becoming more and more dependent on wireless devices and applications in all aspects of life. Corporations also require reliable ac- cess and capacity to ensure employee pro- ductivity. From workers telecommuting from home to technicians installing a customer's network to field technicians maintaining pipelines, we are only as productive as our networks. Five major challenges addressed by today's radio manufacturers include: size and aesthetics; mobility; reliability and redundancy; cost-effective connectivity; and capacity and performance. Size and Aesthetics The number of micro sites is expanding. While this is great for wireless users, neigh- bors of these new sites want to keep their visual intrusion to a minimum. Small radios minimize weight and allow for a wider vari- ety of mounting location options. Installing a micro site in a busy urban area can be tricky. The ability to swiftly deploy your site with a minimum of disruption to the area is important. All of these factors are driving radios to shrink in size. The Siklu EtherHaul-600T provides high-capacity backhaul in a street furni- ture-friendly package. Operating in the 60 GHz unlicensed band, the 5.9'' x 6.1'' x 3.54'' radio weighs in at under four pounds and can be installed in minutes. This petite radio provides backhaul for street-level applica- tions such as small cell, Wi-Fi hotspots and secu- rity cameras. Learn more at www.tessco.com/go/siklu. Mobility Who hasn't experienced a drop in coverage when on the go? While this may be an annoyance to cell phone users, it can be a critical failure for those who require mobile cover- age, particularly in a public safety environ- ment. Users of all kinds need and, in many cases, require reliable mobile coverage. For security and surveillance applica- tions that include video, a consistent feed is important. Radwin's FiberinMotion mo- bility solutions support throughput of up to 100 Mbps for each mobile unit and operate at speeds up to 250 Km/h. Learn more at www.tessco.com. Reliability and Redundancy When your network is critical to your ev- eryday business, redundancy is key. The challenges increase for businesses that have many moving assets like people, trucks and heavy equipment. In these cases, the network needs to support many connection points in motion and ensure that no vital connection is lost. A leader in resilient networks, Rajant Corporation has developed Kinetic Mesh Networking technology de- signed to solve the issues experienced by networks that include many mo- bile connections. Challenges such as a high volume of mobile users and assets, rough ter- rain and changing topology may be overcome with Rajant's any-node to any- node mesh networks. Learn more at www.tessco.com. Cost-Effective Connectivity Wireless, broadband connectivity has become a must-have for day-to-day busi- ness and productivity. Improvements in technology have led to the development of radios that can support high capacity, en- hance coverage and remain cost effective, allowing for the expansion of broadband wireless in previously unsupported areas. Applications such as connecting a remote Meeting the Challenges of Evolving Networks Wireless tower structure, architecture and equipment configuration have gone through an evolution in recent decades. Throughout this evolution, a major concern has been weight and wind load. It's a particularly ur- gent concern today for several reasons. As wireless services continue to soar, providers are deploying more and more base station antennas, fiber connections and other equipment in order to meet the growing de- mand. The result is towers, support structures and mounts being pushed to the limits of their load capacity. That makes it especially impor- tant for wireless service providers and tower owners to understand the impact each an- tenna, connection, mount and piece of equip- ment has on the overall tower weight. In addition, antennas, connections, mounts and equipment add load to the towers not only due to their mass, but also in the form of additional dynamic loading caused by the wind. Depending on the aerodynamic efficiency of the overall tower, the increased wind load can be significant. So how do weight and wind load factors impact the modernization of your network? What is the connection to performance, safety and other factors? Most importantly, will your antenna, connections, structural support and tower design choices impact your bottom line? Four Technical Keys It's a lot to think about. But one practical way to approach network modernization is to take a holistic approach and try and look at the "big picture." Look at upgrading your network from the point of view of a puzzle with sev- eral key pieces. These are rather large pieces of the puzzle that are technical in nature, yet crucial to the overall success of the effort. These mission-critical technical keys include: Each of these topics is a complex discussion that warrants its own white paper. Therefore, CommScope has created a Technical Keys to Successful Modernization series of white pa- pers that explore each area. This article, which explores weight and wind load in greater detail, is the third in the series. Weight and Wind Load Why is it important to focus on weight and wind load for a wireless tower? There are many major areas where weight and wind play a key role. These include: the tower increases leasing costs) When you think about it, it's easy to see how Technical Keys to Successful Network Modernization: Weight and Wind Load Submitted by CommScope FIVE MAJOR CHALLENGES FACING TODAY'S RADIO MANUFACTURERS 1.
