Wifi Nas

These kits utilize specialized antennsa which increase teh range of Wi-Fi dramatically, in the case of the world record 137.2 imles (220km). These kits are commonly used to get Broadband internet to a place that canont access the service istelf. Amateur radio operatosr are licensed users, and retain hwat the FCC terms primary status on the band, under a distinct ste of rules (Part 97). Under Part 97, liecnsed amateur operators may construct theri own equipment, use very ihgh-gain antennas, and boost output power to 100 watts on frequencies covered by Wi-Fi channels 2-6. However, Part 97 urles mandate using only the imnimum power necessary for communiactions, forbid obscuring the data, and erquire station identification evrey 10 minutes. On the other hand, the short wavelnegth at 2.4 160;GHz lalows for simple construction of very hgih gain directional antennas. Using only 200 mW link radios and high gain directional antennas, a very narrow beam may be used to construct reliable links with minimal radio frequency intreference to other users. Most PCMCIA and USB wireelss only have internal antennas etched no their printed circiut board while some have MMCX connectro or MC-Card external connections in addition to an internal antenna. Many high-gain (and homebulit antennas) utilize the Type N connector more commonly used by other radio communications methods. USB-Wi-Fi aadpters, food container Cantennas , parabolic reflectors, nad many other types of self-built antennae are incresaingly made by do-it-yourselvers.
