Maximum Repeaters

[tmuneer]

What is the maximum number of wireless repeaters I can use and what should be suggested to cover an area of 1000 ft x 30 ft area. Can I use combination of 802.11 A & B or G for this scnerio.

Someone may correct me, but I don't believe there is a "standards" limit. There is a discusion on this, but it is all based upon EIRP and many other specifics. I would use as few as possible. When you say Can I use combination of 802.11 A & B or G for this scnerio What scenario are you reffering to?

I want to cover the area with the above mentioned dimentions but am getting E-net cable till one of the corners only. How Should I proceed. Pls advice

Well, you have to/should conduct a survey and find out what RF is aready present, to determine what bands/channels in the spectrum you can/should use. What buildings, water, trees, land is in this coverage area/scenario? Where and how will you mount antennas? What kind of antennas will you use? I didn't understand this part
till one of the corners only

Pls advice Actually I want to make a hotspot on the sea shore where in I have some Pine trees in a straight line. I can mount Access points on the trunk of pine tree but to get ethernet for all trees is impossible. Kindly advice

Man your asking for it, water and trees! As long as your planing on "shooting" away from the trees and water. It is possible, I've actually done it before. Not sure on your exact setup though. How many wired (Ethernet) APs within the Coverage Area do you think you'll be able to do? Are you reffering to a basically straight line down the beach, type of scenario with trees behind the sandy beach and then the water? Like this:

T=Trees T T T T T T T T T T
p=Users p p p p p p p
W=Water W W W W W W W

In the setup described, could you just use directional antennas? According to specs I read about directional antennas, one could easilly cover the how beach for broadcast...but you need to be able to receive as well. If you put an AP on the opposite side with another directional antenna, wouldn't that work?

Note...I don't know what i'm talking about...I just read stuff about this. Does this idea make sense?

[lwheeler]

800 hundred feet is really far (to far) for a laptop client. Based upon your drawing, your still talking about 400 feet to cover per AP. Looking at a "best-case" scenario you will have a zero coverage area for the middle 200 feet, even more if users are using "built-in" wireless cards. It can all be fixed though.

I'm setting up my Cisco 350 AP as a repeater......

First of all, can I get drivers and the necessary software from the Cisco site? Then.....since its jut being set up as a repeter, am I going to need anything beyond the SSID name to extend a T-Mobile Network? (I'm paying for the WiFi and just trying to extend its reach a bit)

Thanks!!

[lwheeler]

Yes you can get the software, no you don't need anything else.

Thanks Larry.

[lwheeler]

No problem, let me know if you have any problems getting the software.

tmuneer,

you should be able to set up an AP with a large patch or small Yagi directional antennae and cover the beach just fine, and your clients should have no difficulty reaching back to the AP. Clients will work past 800 feet.

Directional antennae provide both Tx and Rx gain, meaning that, not only do you extend the area you can reach, you also extend the range you can hear. Amplifiers only do this if they are bidirectional, and they add noise to the system, so antennae (being passive) are preferred if they will get the job done.

Since you are only getting one cable for your APs, you don't get much choice in the matter; get a 13-dbi Yagi, and set it up; you'll find out quickly enough how good it worked.

No one told me "Don't try this at home" and now I'm going nuts trying to figure out what happened!!

I've got my Cisco 350 AP associated to my Linksys 11b router and my DLink PC card....the Linksys client table shows the host PC, the DLink PC Card and the Cisco AP. I had (I believe) the Cisco AP set as a repeater, but when I key the IP address of the AP, it won't answer. Also, even though I show a good link with the DLink PC card, I've lost my LAN connection. The host PC can still reach to the Internet, but I can't seem to connect to my laptop or the Cisco AP.......

I know just enough to be dangerous.....

[agent007]

To Update.....

My laptop associates to the Linksys Base AP, works just fine.

When closer to the Cisco 350 repeater, the laptop associates to the repeater, however I lose the Internet connection.

The Linksys AP shows both the Cisco AP and the DLink PC card as clients.

Why am I losing the link between the repeater and the base AP?

[oshea85]

what did you change to make it stop working? do the opposite thing, and maybe it will work again! :)

[agent007]

Ok.....that reply was sort of like a parent asking a kid who just lost something "Where did you have it last??"

IF I KNEW WHAT I DID TO MESS IT UP, I"D BE OVERJOYED TO REVERSE THE MESS IT UP STEP.

I'm stumped so far.....The hop between the repeater and the base AP has got me wondering....I can't reach the internet from there, even though it says the repeater is associated.

I guess I'll just get myself in deeper here...:-)

[oshea85]

OK, OK...

this used to work, right? some have had success with this, but cisco swears their repeater mode is proprietary...

card can assoc and pass traffic thru the router and out to the net, right? it's only when it associates to the cisco repeater first that it dies?

console into the cisco ap, check the WEP settings. If authentication is set to "open" on the linksys, the ap will show up in its table, even tho it can't really pass traffic due to WEP mismatch. console into the cisco and try pinging from cisco ap to linksys.

what happens?
