To provide sufficient coverage and capacity, IT leaders must consider several issues when deploying networks in these areas. First, high ceilings, open spaces and structural obstacles can all contribute to limited or no radio frequency (RF) propagation in some areas of the venue. Next, in settings where large con- centrations of mobile device users congregate, capacity per user device becomes a significant issue. Finally, many venues require that Wi-Fi infrastructure be deployed in the least conspic- uous, most aesthetically-pleasing means pos- sible so that it does not disrupt dcor. Several new products have been introduced on the market to help IT administrators alleviate these challenges. Select the Correct Wi-Fi Antenna There are two types of wireless access points; those with the antennas integrated, and those with ports to connect to external antennas. Access points with integrated antennas exhibit omnidirectional radiation patterns and provide uniform coverage in all directions. However, these internal antennas exhibit limited cov- erage because the antenna gain is typically lower than the gain for external antennas. Also, access points with internal antennas must be mounted on the ceiling in order to maintain the proper radiation pattern for coverage. Using access points that are connected to external antennas allows greater placement flexibility and provides improved coverage and capacity, especially in high-ceiling venues. For general coverage within a local area, medium gain omnidirectional external antennas are a good choice. These antennas can be ceiling or wall mounted. If higher capacity is needed, directional antennas are a better choice because they offer a broader range of gain and beamwidth options. In addition, the use of external antennas allows the APs to be concealed, usually above the ceiling or inside the wall. An aesthetically-pleasing solution is more easily achieved when the access points are hidden and only the antennas are visible. New Podcast Series Featuring Wireless Industry Experts Submitted by TESSCO Technologies Introducing TESSCO Talk Podcast , a weekly podcast where TESSCO Technologies' Bill Moten talks with wireless industry leaders about the topics that matter.
