Extra Power: A Gift from the FCC
{"Image DocumentName": "Extra Power: A Gift from the FCC", "Image ImageDescription": "The FCC had already decided to place a limit of +36 dBm (4 watts) Effective Isotropic Radiated Power (EIRP) on Multi-Point WLAN links, and a maximum power of +30 dBm (1 watt) at the WLAN tranmitter s connector. So they also defined that if any antenna used in point-to- point links has a gain higher than 6 dBi, the transmitter power must be reduced so that the peak output power of the intentional radiator is reduced by 1 dB for every 3 dB of antenna gain beyond 6 dBi. This is a gift from the FCC. It allows point-to-point WLANs to achieve an EIRP well in excess of +36 dBm, and the greater range that results from the higher power. Here is a table of some typical values: Industrial Ethernet and Networking.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
