April/May 2015 that can install on existing structures such as light poles. For one installation in Palo Alto, the poles were actually disguised to look like surrounding trees. Indoor DAS systems are ideal when you need a lot of capacity. However, small cells, with their potential to cover areas at a lower cost, are growing in use. And Wi-Fi is increasingly deployed in conjunction with cellular-based technologies. The "Big Game" Case Study From the previous "big game" to the most recent, data usage increased from 177 Gb to 696 Gb-a 300 percent increase in mobile data traffic. To prepare for the big event, AT&T considered the venue as well as the surrounding areas. They updated the sta- dium to accommodate three times the Wi-Fi capacity of the previous year, installed DAS at nearby locations and implemented a "cell on wheels" system for temporary coverage. There were actually two DAS systems de- ployed: an indoor system utilized 48 sectors to provide coverage for the stadium and was used by all the leading wireless providers, and an outdoor system was deployed in the parking lot through air vents on the exterior of the stadium as well as poles throughout the lot. Antennas were also installed at the West Gate Entertainment District, where many of the pre- and post-game festivities were held. The results? Over 696 Gb of data was consumed within the stadium. That's about 1.9 million social media posts with pictures. Lump that in with the outdoor traffic and over 1.7 terabytes were consumed or 4.9 million social media posts with pictures. What's Next? The market must continually transform to reflect changing needs. Wi-Fi, for example, has been primarily used for data. But with the growing demand for Wi-Fi calling, its importance within HetNet systems may significantly increase. This could be po- tentially disruptive to the in-building mar- ket. And the industry needs to stay on its toes to keep ahead of these changes and disruptions. TESSCO is ready to bring the newest solutions and technology innova- tions to its clients in DAS, small cells, Wi-Fi access and beyond. (continued from page 1) HetNets-The Future of Wireless Networks Rethink Wireless Backhaul: More Speed, More Places The challenge for any wireless operator today is increasing bandwidth per coverage area. How do you provide more capacity to more users with more devices? Fiber is always the first choice. But how do you take that fiber from where it ends and extend it out to where it needs to be? Enter Fastback Networks, this year's TESSCO One Innovation Showcase Award Winner in the Active Components category. Solving the Challenge of Wireless Backhaul Networks are moving closer to users and wireless capacity is increasing. Backhaul is becoming a critical aspect even as new problems for backhaul systems are cropping up, such as non-traditional mounting locations, size and power limi- tation, site acquisition and line-of-sight challenges. So, what is needed? Wireless opera- tors need to deploy backhaul in more locations with higher predictability. Fastback is helping to fill this need. Fastback provides LTE backhaul for voice and data utilizing a single integrated de- vice. It provides a fiber equivalent where fiber cannot go. Fastback's largest de- ployment is with Tier One mobile operators, but it is also gaining momentum with backhaul operators, fiber providers, public safety networks, small cell fill-in and even temporary backhaul providers. Benefits include: man install, cutting down speed to market radio, antenna, CE2.0 switch and fiber connection all in one package capable of making multiple decisions every millisecond leveraging 3D and ray tracing technology Tier One cellular service providers low latency to sway Real World Applications Though Fastback debuted at the TESSCO One Showcase, it has already seen extensive use with hundreds of links installed in Tier One U.S. networks, including a Cellular of Wheels (CoW) deployment by a Tier One operator at this year's Super Bowl. Other operators are already seeing the advantages in the field. In one instance, a mobile operator put a link up, and within 18 months a building was constructed directly in the path of the link. The link was unaffected. Fastback's ease of deployment makes it ideal for even a temporary install. In instances where fiber may take six to nine months to get pulled in, Fastback can be installed quickly and replaced with fiber later. And during site acquisi- tion, when operators are charged according to the size of the footprint needed for equipment, Fastback's inte- grated unit provides better purchasing leverage. The benefits are plentiful. Visit www.tessco.com/go/fastback. For more information, visit www.tessco-one.com.
