How to Create an Enterprise Wireless Infrastructure
Providing efficient, effective wireless coverage within a major structure, whether it's a skyscraper or a sports stadium, can be more than just problematic. As MobileAccess Vice President Jeff Kunst explains, it takes careful planning and the right kind of antenna system. For another look at how this problem was solved in the real world, see eWEEK's article on wireless networking in the Hearst Tower.Today's enterprises embrace wireless applications that depend on an array of wireless technologies and frequencies. While IT departments are most familiar with WLAN-based applications, consider the escalating indoor use of mobile phones and PDAs, the regulatory push for public safety radio coverage in large venues, and the buzz surrounding new Mobile WiMax and 4G technologies. Unfortunately for the IT department, most large enterprise facilities are black holes from a wireless perspective-wireless coverage doesn't just happen. Most often, RF (radio frequency) signals are blocked by a building's reflective glass coating or signals are absorbed by dense structural materials so they're unable to evenly penetrate the building's core. To ensure "five-bar" wireless coverage indoors, IT managers need to deploy a "plumbing" infrastructure for wireless. Known as DAS (Distributed Antenna Systems), these infrastructure solutions overcome a building's inherent structural impediments and deliver robust wireless coverage throughout the facility.
