AT&T, Inc. Enhances Mobile Internet Coverage In The Detroit Marriott Renaissance Center. New 4G LTE Distributed Antenna System Provides Additional Wireless Capacity for Customers. As part of its continuing network investment to support growing demand for advanced wireless devices and services, AT&T has improved its mobile Internet coverage at the Detroit Marriott Renaissance Center by completing the installation of a new 4G LTE-capable Distributed Antenna System (DAS).

A DAS installation consists of multiple strategically-placed antennas that distribute AT&T's wireless network coverage throughout the Marriott, providing for more efficient management of wireless capacity in heavily-trafficked areas including guest rooms, the hotel lobby, ballrooms, guest circulation areas, meeting rooms, executive offices, fitness club, and more. DAS has the ability to provide enhanced, more consistent wireless coverage to customers in indoor or outdoor spaces where geographical limitations -- terrain, building construction, etc. -- or crowd density might otherwise prevent the optimal wireless experience.

The additional capacity is expected to help improve call reliability, boost data traffic capacity and enable more consistent network access so customers make the most of their AT&T devices. This unobtrusive network solution is just one innovative approach AT&T is taking to ensure it provides a seamless and effortless customer experience. AT&T has deployed two compatible 4G technologies to deliver more speed to more customers, which means AT&T customers can get 4G speeds outside of 4G LTE areas on 4G HSPA+, unlike competitors, where smartphone customers fall back to slower 3G technologies when outside of LTE coverage.

4G LTE network delivered faster average download speeds than any of competitors in PCWorld's most recent 13-market speed tests. AT&T's 4G LTE network delivers speeds up to 10 times faster than 3G, as well as multiple innovations that optimize the network for performance. Network's radio components are placed close to the antenna at most cell sites, instead of inside the base station, which helps minimize power loss between the base station and antenna and, in turn, improves the performance of 4G LTE network.

The network also is designed with its core elements distributed across the country, which helps reduce latency, or the delay when using the Internet, because request isn't traveling as far.
