Que tal bakunos, me gustaria saber sus opiniones respecto a este amplificador de wifi que difunde a 25 watts el cual promete tener una ganancia de 25 dbi de recepcion contra un emisor modelo DWL-2700ap wireless outdoor ap/bridge (
http://www.cyberpuerta.mx/Computo-H...nk-Poe-2-4GHZ-54-MBPS-SNMP-AP-WDS-WDS-AP.html) Cabe mencionar que el amplificador se usaria con un router cisco wrt320N.
Por qué pregunto esto? Porque me interesaria saber si tienen algo mejor que sugerirme para cubrir un radio de 4 kilometros cuadrados de manera inalambrica reduciendo el costo del hardware a no mas de $ 20,000 pesos mexicanos considerando solamente la difucion de wifi.
Les dejo el articulo completo para su completo entendimiento
HyperLink TI series are high power indoor RF amplifiers for 2.4 GHz spread spectrum wireless LANs. High power and excellent linearity make it the highest performance wireless LAN amplifiers available today. These WiFi amplifiers are compatible with 802.11b wireless LAN equipment. Hyperlink's APC (Active Power Control) circuit automatically adjusts the amplifier's gain to provide a constant output power regardless of cable length. Consisting of a receive amplifier and a transmit power amplifier, the "TI" series installs indoors near the radio itself, combining ease of installation with significant improvement in operating range and performance.
The "TI" series WiFi amplifiers increase range by providing transmit gain as well as 24 dB of receive gain. This receive gain actually increases the receive sensitivity of most wireless LAN radios. This unit can be configured to deliver full transmit power with as little as 1 mW of input power. This feature permits cable runs of several hundred feet with no degradation in operating range.
Our design features 32W FET allowing these amplifiers to deliver full rated linear output in 802.11g mode.
The TI amplifier features a heavy-duty enclosure machined from a single block of aluminum making it suitable for demanding commercial and military applications. Included with the amplifier is a 12 VDC @10.8A (130W) power supply.
Operational Note:
This Hyperlink bi-directional amplifier is designed for burst half-duplex operation. It is not intended for constant transmit or CW operation. Operation of the amplifier in CW mode will damage the amplifier and void the warranty. Also note the following warnings, the maximum VSWR (antenna, cable assembly, connectors, etc) coming into and out of the amplifier is 1.5:1 and the maximum input power is 100 mW. Failure to observe these warnings may also cause damage to the amplifier and void the warranty.
