One Mile WiFi? So Says the ParkerVision 1500WR

THIS KIND OF PERFORMANCE TRANSLATES INTO FULL COVERAGE FOR YOUR ENTIRE HOME. In every single room! Through walls! Down corridors. OUT BY YOUR POOL. Across the open fields. In the middle of the city. Stupendous range. This router Features advanced D2D™ transceiver technology, from ParkerVision. This means you will experience no loss of EFI signal! No dead zones!! And that's guaranteed. Nearly a country mile's worth of OPEN FIELD wireless coverage. Think how big a mile is - it's 5,280 feet. Then think about the possibilities."</i><br /><br /><img src="http://images.tigerdirect.ca/SKUimages/medium/p999-1004-main-6.jpg" /><br /><br />I found this product quite interesting - it's $326 CAN, about triple what a normal 802.11b access point costs, but it's more than three times as powerful. Heck, I'd settle for paying twice as much for an access point and getting twice the range. Since I switched to using my Fujitsu P5010D, I haven't had any range problems when combined with the ill-fated Microsoft MN-700, but now and then the signal will drop or it will switch networks, presumably due to a stronger signal being detected (man I hate that). And, yes, I have the "connect to non-preferred networks" box un-checked.

........yeah, but the range on laptops, and PPCs falls about 4,280 short on the return! ;)

Still pretty cool though.

Two points
Note: 1 Mile claim based upon open-field testing in which coverage of more than one mile was achieved using ParkerVision complete solution of the WR1500 and WLAN1500 or USB1500 adapters.

And there's no CF card, so this sort of range isn't happening with PPCs.

Note: This product is guaranteed to improve any existing compatible wireless network, and if used with ParkerVision 1500 series adapters, is guaranteed to cover your entire home, with no dead spots.

There's two ways to increase RF range, more power out, more receiver sensitivity. Power out is limited by the FCC, receiver sensitivity is expensive to make substantial gains in (until the technology catches up). To get real benefit form a breakthrough in receiver sensitivity, you need to apply it ot to the receiver at both ends of a full duplex circuit, i.e. to the one in your PPC as well as the one in the AP.

This might give you some better performance but at a cost higher than just getting a second AP or a range extender.

IN the US you should add.... ;)

It's 50 less if you go to ParkerVision's website and it's also able to be sold in the US as well so this thing is for real folks. www.parkervision.com

for bridging 2 networks i guess is very useful :)

A PPC with USB Host capability, like the Toshiba e800 (http://discussion.brighthand.com/showthread.php?s=&threadid=104328), could use the ParkerVision USB wireless adapter (http://www.direct2data.com/1500usb.htm).

I wouldn't touch it with a barge pole.
The rule of thumb I apply to this sort of advertising is that as with exclamation marks, anyone who makes such extravagant use of capital letters is either insane or has the soul of a spammer (the last being an oxymoron I know).
Even if the product is technically excellent, I know straight away I'm dealing with jerks.

Is a barge pole at least 10 feet long? If so, I'm with you :lol: Now as soon as they can get that pesky cancer cure incorporated in it, I'll jump right on this :lol:

".... gives you an astonishing 5000 feet of ... wireless coverage.

...then i would definately make sure my balls are at least 5000 feet away from this radiation source! :lol: This is $326 CAN for a sterilization and a AccessPoint.

What do you think the chances are for a Toshiba USB driver for this :?: My statement stands :wink:

I'm curious incidently, is there a USB camera driver for the USB host capable PPCs? You , know, for like a Logitech web cam.

Yea, you are right. But most other countries have their own transmission police that defines frequencies and power limits. Some more restrictive than the US. In smaller countries the chance of interference is more prevalent.

Actually there's a third 3) More Efficient Antenna system.

I've talked around the world using very little output power ( 1-5 watts) and the reason I could do it was because of the high gain yagi array on top of my house.

The key words with this ap is "open range" meaning no obstructions what so ever. They are saying that if you put this ap in the middle of a flat area with no trees, bushes or anything else to obstruct the transmission then you can achieve 1 mile. Thing is this is true with just about all the ap's on the market. It's the same thing with cellular, in dense obstructed areas you need more cell sites to help with in building coverage and to handle more calls. When you move that same cellular system out in the middle of no where you can space them out further because less obstructions mean the signal can propagate further.

And the frequency at which you were operating. I don't think that is happening at 2.4GHz no matter how big your antenna is. Besides that, antenna efficiency usually comes at the price of directivity. Good point though, missed that one.

For bridging networks however, you can get greater ranges for lower cost using various cantennae style implementation on existing equipment.

Sven,
Remember that seattle open wifi project with huge coverage?
Phased array style antennae? What do you figure a home-bake version of Ap's and equipment could cost? :devilboy:
