    Wireless Array depending on the types of materials and background RF (radio frequency) noise at your location. To maximize wireless range, follow these basic guidelines: Keep the number of walls and ceilings between the Array and your receiving devices to a minimum — each wall or ceiling can reduce the wireless range from between 3 and 90 feet (1 to 30 meters).

    Wireless Array Custom Coverage Where there are highly reflective objects in proximity to the Array, you can turn off specific radios to avoid interference and feedback. reflective object Figure 12. Custom Coverage Capacity and Cell Sizes Cell sizes should be estimated based on the number of users, the applications being used (for example, data/video/voice), and the number of Arrays available at the location.

    Wireless Array Fine Tuning Cell Sizes Adjusting the transmit power allows you to fine tune cell sizes. There are four standard sizes — Small, Medium, Large, or Max (the default is Max). There is also an Auto setting that automatically determines the best cell size, and a Manual setting that allows you to choose your power settings directly.
  • Page 56: Roaming Considerations

    Wireless Array Sharp Cell This patented Xirrus RF management option automatically creates more intelligently defined cells and improves performance by creating smaller, high- throughput cells. By dynamically limiting each cell to a defined boundary (cell size), the trailing edge bleed of RF energy is reduced, thus minimizing interference between neighboring Wireless Arrays or other Access Points.
