Microsoft WhiteFi: Next-Gen Wi-Fi Standard? : Read more

does it have good penetration (dont say thts wht she said), cause my wifi has to go through a good half dozen 100 year old thick wooden walls. although i guess we got analog tv before so i would think tht would prove its worthiness. my 802.11g is a reallll stretch where i am.

@AMDnoob

That's what she said! LOL!!!!

 

[marokero]

Would WhiteFi work at all in countries that still use the UHF band to transmit tv signals? There would be a lot of interference I assume.

Microsoft has lost it's position as a standard creator, IEEE and the Linux Foundation, and other Open Source Consortiums have pretty much knocked them off that throne. MS execs always decide that they have to close-source/cock-block atleast some part of any standard, not much of anything they do is truly open...

 

[matt87_50]

yeah, as far as wifi specs go, bandwidth is at the bottom of the list for me at the moment:
latency,
CONSISTENCY of bandwidth,
penetration,
range (makes wifi hotspot blanketing more realistic),
then bandwidth.

 

[Regulas]

Neat but would you want your home network to be able to broadcast that far?
And it should be open source code, if the convicted monopolist MS is involved they will screw it up for cash in their pockets somehow.
Maybe for specific purposes but not a good idea for all WiFi situations.
I know some cities were trying to get city wide WiFi, this would fit that bill nicely. But since I am paranoid when it comes to anything to do with the government I would be wary using anything they offer.

^^^^^^^^^^^^
Yeah, it would be nice to be able to use my home wireless connection around town (I live in a small town), but I don't think I would want everyone else to be able to try.

I understand that they are researching with the space previously occupied by analog television signals. Didn't they have anything else in mind for that part of the spectrum when they transitioned to digital? I have not heard any specifics.

I thought that the government wanted to switch over so that they could auction off that spectrum range... Maybe Microsoft or ISPs will be in on this?

miles rather than feet, microsoft, dont stick!!!

Could possibly work as a free slow speed public wireless internet, in sort of the same spirit as the TV signals it would replace

 

[iquark]

The problem I see is that it takes much higher power to output the lower UHF frequencies than the microwave UHF frequencies. This would be fine for something like city wide Wi-fi, but for home use it doesn't seem cost effective due to energy usage.

Also, wouldn't White-fi antennas have to be a bit longer due to change in length of the ~500Mhz frequency. It's about 12cm for a full 2.4ghz wavelength antenna vs 15cm for a quarter length 500Mhz antenna. This could cause problems with component space considerations.

Sounds interesting though, at least you know there's plenty of throwaway money with microsoft behind it!

It would work pretty sweet for in-vehicle infotainment type of deal.

It would be great if a 'Green-WiFi' would finally be introduced.

TCP/IP requires 2 way communication to work my friend...

but if one wifi hot spot was 1 mile in radius...... Bring in a fibre optic connection to the transmitter and bingo, one good public access spot. all the small villages could get decent connections.

or, internet connection via this could eventually replace the need for telephone lines. fiber optic connection point, each ISP have their own white-fi broadcaster/receiver and you pay for your access (password) to said network.

yeah yeah, so u need a box at your house that communicates 2-way with the ISP transmitter. but why wouldnt that be possible?

anything to get rid of the copper wire i say.

1000 bucks the FCC won't allow it!

But would you have a transmitter on your laptop? No I don't think.

This whole idea is great to augment the existing wireless networks we have access to, but it cannot replace a wireless home network. I can see this as the connection from the home/hotspot to the provider, but everything local would still be a/b/g/n/x. The battery consumption to transmit this signal even within a single house would make it impractical for laptops and other mobile devices.

I could see the same thing. Using the same signals as the TV uses is something many countries have not stopped using (the TV broadcasted to antenna to TV), so basically the US will get its piece of the pie first, then the rest of the world.

 

[shabaa]

If it is done by Micro$oft then expect bugs in it and in a few years when the bugs are ironed out they will release a "new and improved" networking type and the upgrade will cost more... and it will be buggy as well until the next release.....and so on..(just a snapshot of the business model)

 

[ptroen]

Presumably with UHF broadcasts been leaking out to space for a while now, ET could just hookup with his PC and message you on MSN.

On November 4, 2008, the FCC voted 5-0 to approve the unlicensed use of white space....

 

[geoffs]

[citation][nom]AMDnoob[/nom]does it have good penetration[/citation]That's one of the big advantages of < 1GHz signals, they have significantly better ability to penetrate walls, etc.

The other major advantage is that transceivers and circuitry require less power to operate at those lower frequencies.

The down side is that with longer range and better penetration through walls, security and interference from other devices using the same frequencies can become more of a problem.
