In-Building Market Trends

With the increased proliferation of mobile wireless devices, subscribers expect to have wireless coverage in any place they go. Providing seamless coverage everywhere can be challenging, particularly inside buildings.

Carriers implement indoor coverage solutions to increase customer acquisition and retention. A key explanation subscribers give for switching carriers is unsatisfactory network quality. Most often, the highest value subscribers are business users. Providing indoor coverage at business locations can improve subscriber satisfaction, extend service contracts and prevent costly churn. There is clearly an opportunity for wireless service providers to improve profitability by creating a superior network that includes indoor coverage. Nowhere else are mobile voice and data users able to so closely scrutinize the quality of their providers network performance.

The onset of higher speed data services requires service providers to design their networks differently, resulting in an increased priority for indoor coverage. Data users often use their mobile devices within office buildings and will not tolerate dropped calls or inadequate service for transfers of data. In addition, third generation services will result in smaller cell sizes, causing the macro network coverage to be insufficient for thoroughly penetrating buildings, particularly new construction materials with high RF attenuation properties. A dedicated indoor coverage solution can improve macro network coverage because it offloads capacity from the macro network.

In-building needs are everywhere, including corporate campuses, traffic corridors such as tunnels and subways, coverage holes, capacity hotspots, and public spaces such as airports, hospitals, government centers and shopping malls. With increased attention on public safety, more cities and counties are passing ordinances that require buildings of a certain size to have coverage systems in place for the communication systems of public safety officials (Fire/Police/EMT). In such applications, often 150,000 square feet or larger, the economics of passive solutions become less attractive.

There are many alternatives for providing indoor coverage at different price points. Beyond the initial price, it is critical to consider long-term cost, benefits, and the limitations of each. Given the constant changes in today's wireless landscape, the best choice is the most flexible, scalable, reliable, and quality solution available.
