In response to a number of requests for a passive antenna booster, or simple means to enhance the range of a cordless phone, a mobile phone (cell phone), a local WLAN (Wi-Fi), or any other low power radio device, particularly in rural and cellular fringe areas, herein are some possible solutions available. To help you assess how to best achieve your desired goals, below are links to range estimation charts derived from an old, but generally trustworthy propagation model developed many years ago for our own internal use. Charts are provided for the key ISM bands of 900 MHz, 2.4 GHz and 5.8 GHz. If your application lies at other frequencies, use the chart nearest your band of interest. We will add other charts as we receive requests to do so.
Instructions for the use of the above charts are at the bottom of this page. Three typical case studies are evaluated in the following links to review the potential benefit of a Passive Booster system. You can augment the performance of a Passive Booster through the strategical addition of a bi-directional amplifier. Such devices will be offered here by early 2008 and we will expand these instructions to include directions on how to add a bi-directional amplifier to a Passive Booster system.
