wisp

I'm preparing to start a mini wisp and expand from there.

At this moment I have a Cisco omnidirectional antenna. I plan to broadcast out around 5 miles. I getting ready to get TV antenna tower probably 50 foot.

My question is. what will i need on the customer end so that they connect to my network but are actually on their own network. I'm thinking something like a DSL modem type thing only for wireless. see i plan to broadcast a 10.x.x.x address and they will need a device to give them a 192.168.x.x address. My reason being is that i don't really want the customers to be able to browse network neighborhood and see other peoples files or printers.

About my connection.
I have DSL. I already talked to the owner of my ISP and they do not have a restriction on reselling the service as he is also a CLEC.

Cisco omnidirectional antenna. I plan to broadcast out around 5 miles.
That antenna will need to get real high gain type.Also your customers will need a clear view of your antenna and a real high Gain directional antenna.

I suggest you do some experimenting before you drop any big money. 5 miles at 2.4GHz is a long way.

2 watt booster will help.
example.

Could get spendy right quick. :(

The pc's may be able to recieve the signal but they will not be able to transmit back that far with out some hagh gain equitment.

And I believe you've got some FCC issues here. The spectrum may be unlicensed, but the amount of transmit power you're allowed to pump out is restricted.

Very good point. I don't know how the US does it, but down here 2.4 GHz and 5.8 GHz are "class licensed" rather than "unlicensed" -- there's a standing license for devices playing by the class licence conditions, but if you exceed those then you're unlicensed and therefore illegal.

I've never done anything like this so I can't offer too many details, but the customer end is the wrong place to be doing that (or at least can't be the only place) -- you need to be blocking broadcasts at your end if that's what you want to do. CPE can be replaced, modified etc. :) Your customers will probably have pretty directional antennas, so the odds of them talking without going through you is very slim.

2.4 ghz is in the unlicensed range. you gotta be careful with the signal boosters that will cause a problem with the FCC. as long as the tower height is under 160 feet you won't need to worry about the FAA. and if you ask the farmer first you don't need to worry about the FFA (joke).

Don't bank on the 160 ft. tower height.

Most of it depends on where it located.

Also, Antenna Tower Lighting and Marking Requirements

I see people with tv antennas that are close to 50 foot in height. I was talking to a ham operator that said his tower is 75 foot. How do they get away with it?

i have a nearby tree that is close to 50 foot high.

It's receiving a signal, not broadcasting right? Maybe he is breaking the rules, I thought the guidelines were 25ft higher than the highest point on your personal property.

On a side note. I just received my Cisco 871w router today.

ok kids I called the fcc and they do not deal with antennas for wireless internet. They said it is up to my township zoning board. my township is not zoned so i'm clear. i'm in the process of procuring a 40' windmill tower. I won't need to worry about the FAA because there is a high tension tower about a tenth of a mile away and they are much higher than 40'. as also mentioned before my tree is close to that height.
