hi to all ,
we have a WISP now and we need to perform a laptops service for our costumers , and we want to make the connection available for roaming users , from the street , malls and from many areas .
we have now SR2 with RB/532 and 15dbi omin for each station .
the sensitivity is good for our clients with a 12dbi patch antenna and SR2 or cb3 radio , but we need to deploy the laptop solution to enable the laptops to connect directly to our base stations .
we will deploy also an SR2 or NMP-8602(26dbm) mini-pci for the laptop users , or they may will use there based wireless card built in the laptops which is 35mw :S (mostly will deploy SR2)
now i can increase the base station Signal power by using an AMP for say 1 watt or 2 watt , and the laptop romaing clients in the city can listen and find the ssid with a good -db level say -70 . but i cant connect ofcourse from far places but i can now from inside bulding near to the street and after that no any buildings in the way with the BS ,,,, i dont have any problem in the speed the minimmum speed is good , even 5kb/s , just somthing that made the connection happened .
my question is how to increase the recieve sensitivity level in my Station the SR2 -db level limit is -98(+/-)2 , but i need more !! any ideas to increase this for say -106db ? bigger antenna ? an ampilifier to increase recieve gain ? filters ? recieve divirsity using 3 omini directional antenna with 120 dgree ?
what is the best to perform , and thanks in advance .
