Denser HetNet Needed to Keep Up With Capacity Demands Submitted by Tracy Ford, Director of the HetNet Forum at PCIA-The Wireless Infrastructure Association Hear How at HetNet Expo The numbers are staggering: AT&T claims that mobile data traffic on its network has grown 100,000 percent in the last eight years. Mobile video-a bandwidth hog-accounts for more than half of today's network traffic and is expected to grow by more than 10 percent each year, according to Cisco. To keep up with increasing traffic demands on the network, wireless service providers are deploying technologies designed to bring the network closer to the end user. This densification ef- fort continues even as operators use other tools in their toolbox, such as Wi-Fi offload, since the demand for connectivity contin- ues to rise. No single solution is going to remedy the increased traffic on the network, so the industry is building the heterogeneous network, or HetNet. The HetNet provides increased network coverage, capacity, and quality through the use of a variety of infrastructure and technology, enabling seamless voice and data communications. In other words, mobile connectivity solutions are becoming more complex as more frequency bands, tech- nologies, and solutions are deployed that require compatability. While a Distributed Antenna System (DAS) solution might be best suited to a large public venue where thousands of people congregate in a short period of time, a small cell solution- whether it be microcells, picocells, or femtocells-might be a better option for a two-story office complex. Operators are scrambling to keep up with the intense demand for mobile connectivity. The nation's top four wireless operators spent a cumulative $34 billion in 2013 to make their networks strong enough to handle today's connectivity demands, accord- ing to Recon Analytics analyst, Roger Entner. And the spending continues. However, even such large infrastructure spending is not enough to bring advanced communications to all buildings and venues across the United States. Wireless service providers have to prioritize upgrading locations based on a wide variety of criteria, including, but not limited to, funding budgets, location demand, ease of upgrades, and their own projected return on in- vestments. Funding models will vary depending on the perceived value of the venue. Today, three basic funding models exist for DAS deployments-carrier-owned, enterprise-owned, and neu- tral-host-owned. All ownership models require carrier approval since the wireless operators own the spectrum involved. Small cell deployments are just underway and their funding models will evolve as more are deployed. To help understand current industry trends, the HetNet Forum, a membership body of PCIA-The Wireless Infrastructure Association, offers an annual educational and networking event called HetNet Expo. This event takes place October 27-28, 2015, at the Millennium Biltmore Hotel in Los Angeles. Keynote speak- ers include: Verizon's Eric Fitzgerald Reed will address the consumer and industry trends that are necessitating more network densification. Asad Rizvi of Nokia Networks will discuss his vision of the programmable world and networks of the future. Chetan Sharma will talk about the evolving world of connected intelligence. Boingo Wireless' Derek Peterson will chat about the Mobile Mind Shift -the expectation that people can turn to their smartphones for the answer to everything. Marc Ganzi of Digital Bridge Holdings will explain why he is betting big on small cells. The HetNet is evolving beyond commercial cellular boundaries. Public-safety officials will have access to 700 MHz spectrum, but a new 270-page report from the Department of Commerce's Public Safety Research Program notes that in-building coverage needs to be supplemented with a combination of small cells deployed indoors as well as Cell on Wheels (COWS). Hear from one of the authors of this study, as well as a Los Angeles Fire Department battalion chief, on challenges facing the public-safety community. "Smart Cities" and the "Internet of Things" are among the hottest buzzwords used today. Experts on the front lines in those fields will share how tangible efforts are being made in those areas, including the U.S. Navy's Smart Shores Initiative and The Connected Car . Dive down into the weeds and ask tough questions during our Ask the HetNet Experts panel , using the social media tag #hetnetexperts. Learn best practices for tackling the mid-tier market, which still needs robust wireless coverage and capacity, but may need a new business model for successful deployments. Regulatory challenges continue to exist. Hear how the gov- ernment is working to remove barriers to deployments from the Federal Communications Commission special counsel.

HetNet Expo 2015 will bring together the leading DAS and small cell solution providers to discuss the technologies that are the foundation for the future of our connected society. When mobility intersects with people, places and things, everything changes. Attendees will be provided with a realistic roadmap for today and beyond. Make plans to attend the industry's leading DAS and small cell event today. HETNETEXPO.COM
