Just curious, is range all that important? Usually if the range is far, you would not be able to use the optimal modulation like 64 QAM for best performance due to signal attenuation, noise and interference. So, you would end up with a much lower attainable speed. IMO, it may be better to keep the range at 1 mile but give users in that covered area with more realistic throughputs.
I like GMail because it supports AJAX, and Yahoo! Mail seems to be behind in this area. Then, I chanced upon a Firefox extension that adds AJAX support to Yahoo! Mail. It's pretty neat.:)
Those users who are less techically-inclined usually have problems enabling encryption on their wireless networks. Sometimes it is due to the poor documentation (e.g. undescriptive and full of jargons) of the wireless router / access point; sometimes it is the poor implementation (e.g. confusing user interface) that hinders the use of encryption on the wireless network. And because of this new ruling, there may be many home/business wireless network owners fined for their insecure wireless networks.
Here in my lab, we regularly see ghosts on our PCs, especially after they are plagued with spyware, worms and virus. Perhaps the PCs got too sick and died?
Oh, by the way, ghosts are named "Norton".
Can someone please shed some light on what the referenced paper titled "General Relativity Resolves Galactic Rotation Without Exotic Dark Matter" is talking about? I seem to be searching in the dark all these while.
This is another great site on DIY antennas for USB WiFi adapters. I have made this one for my D-Link G122 USB wireless adapter and not surprisingly, it worked really well!:-)
VoIP over wireless networks. Is it all that rosy? I wonder...
Firstly, the handheld devices have to be powerful enough to support the coding and decoding of the real-time audio stream. Then, there's the issue with battery life. With all that processing required, support long conversations. Will it be possible to have a "standby" mode for these devices, such that they can be constantly connected to an access point and receive incoming calls? How long can the device remain in "standby" mode per battery charge? My cellphone can do that for a day or two, but I am skeptical that a handheld device can stay connected to an AP for more than 12 hrs.
Will the handoff procedure of the mobile wireless VoIP be as seamless as that of the cellular phones; will there be call breakage when the user roam from one AP to another? How about the quality of service, taking into account the performance variability of the 802.11a/b/g wireless network?
Oh, it seems that WiMAX could provide wireless network access for handheld devices? I wonder how big (and heavy) the device will be.:-)
For those interested to know more about the security issues associated to VoIP, you may wish to read this article. I think it's a great article as it talked about the three important aspects of VoIP security: confidentiality, availability and integrity.

...that Google wouldn't offer?

gmail : k.i.s.s. interface, allowing for rich text
yahoo : no rich text possibilities found
Actually if you had used the Internet Explorer, you would be able to enable the rich text capability of Yahoo! Mail. Ahh I see, you must be on Linux.

While we get awed by this new wireless technology, let us also update ourselves on the developments of WiMAX here.
Warm sashimi... mmmmm.... yummy!

You might wanna read this article as well. It offers a great introduction to the VoIP security issues.
Just pack along a couple pr0n DVDs. ;-)
But the operating system that came along with the laptop is still as fragile as can be.
Sun could introduce some new brilliant talents who may spark them off to a brighter future.
Now, I can see how pillow fights may be a form of biological warfare. ;)
You might wanna read the review on Ubuntu 5.10 Breezy Badger, while you download the ISO.
could be more scratch-resistant than the current ones.

a $2 million contest for driverless vehicles over a 132 mile course in California's Mohave Desert.
The car is powered by 7 Pentium M laptops. No drivers? Are the laptops running in Safe Mode? Ah, that explains why its average speed is 19.1mph.
Does it comes with a fire wall?
... "sounds" like VoIP if you ask me. ;-)
Please post your crap here instead and leave Wikipedia alone. Thank you.
