Wireless range reviews

[isheikh]

Where can i find information on wireless range reviews. I am looking for the wireless router that will give me the maximum range.

Also does anyone know of a two-mile radius wireless router?
Thanks.

Hi,

You need to be more exact about what you are trying to achieve. Are you trying to get coverage for laptops or wireless bridges?

If laptps than there is no such router

If bridges than any commercial grade ap with the right antenna will do the 2 miles

Hi,

Thanks for the reply. It is for a wireless router or access point. Can you suggest a good make. Thanks.

It can repeat as well

looks promising. very large range. have you used one before?

[ConnClark]

Yes I have. I helped design it. Currently, range is being limited by a timing parameter in the 802.11 spec ( The speed of light isn't fast enough). We are working on a software workaround to reprogram this parameter that may extend its range farther.

I can understand any skepticism, you might say I'm a little biased. You might be able to talk our sales people into letting you evaluate the product before comitting if you would like to try it.

any other products perhaps slightly cheaper for the smaller office environment with this kind of radius?

I know very little about FCC regs and such, but it it possible to use this thing as an AP in the United States? 1 Watt????

Thanks.

1Watt is the limit for 2.4GHz ISM band use, so yes this is usable in the U.S.

[ConnClark]

the 195E is FCC certified for use in the USA and DOC certified for use in Canada.

Just don't go hooking up a 33dbi gain dish to the transmit antenna jack and try to cook birds in the air. This runs a fowl of several laws :D (including the laws of thermodynamics)

Thanks for the info....

How much range can I expect to get from that unit to a standard PC card?

I'm thinking wow at the moment...

[ConnClark]

Thats very hard to say, it depends a lot on the card your using and what your comparing it to. You may not get more range with a powerful AP if your card has a very weak transmiter. You will get a lot fewer lost packets from the AP, which will equate to better performnce however.

The only real way to tell is to try it.

[isheikh]

Is there no review or comparison chart anywhere that shows the various cards and there transmit range along with ap's and routere?

[agent007]

So.....hhmmmm....

This could be used as a vehicle mounted 1 watt repeater in between a .11b/g client card and a base station AP??

With 1 watt in a nearby vehicle, it sounds like it would work well in and around shipyards where theres alot of containers and hulls to blast thru.

Am I on the right track?

Thanks...

agent007,

The 195E could be used for that with some restrictions. In our current AP repeater code the AP repeater in the car could be configured to relay packets to/from one base AP station and the client as you describe. A roving AP repeater will not work in a where another repeater is required to get to the base AP because our current code cannot figure out how to find the base AP reliably as the roving AP repeater roves from one fixed repeaters area to another(it gets confused). To do more than one repeater you must configure each repeater to tell it what unit to repeat to.You can configure the 195E to be a client and use multiple fixed repeaters to get back to the base AP (we have a police department doing this with our older 192E product).

to summerize

(Base AP)-----(roving AP Repeater)-----(client)
works

(Base AP)---(fixed AP repeater)---(roving AP Repeater)--(client)
doesn't work

(Base AP)---(fixed AP repeater)---(fixed AP repeater)--(client)
works

Note there are work arounds but it require manual reconfiguration of the repeaters for the roving AP repeaters route. So in other words its a pain in the ass.


Also note that this only deals with units we make as repeating is not standardised and the AP repeating feature will generaly only work with equipment from the same manufacturer (the clients will continue to work as they think they are talking to a normal AP). It should also be noted that we may come up with a solution to over come this limitation in future firmware but I have no idea when.

As for a shipyard with lots of containers I can't say we will blast through them for sure. The signal will bounce around quite a bit and may make it though.

Understood. Good information.

Thanks, now I have to check on pricing.
