ok, i just don't understand wireless N.

I have a spec'd out tx2500 tablet which supports wireless N, what is it?

 

It is the next standard after 802.11g, which gives better speeds/range than g. But it's still in draft form I think...

 

IEEE Standard 802.11N (Wireless N) is the next Institute of Electrical and Electronic Engineers (IEEE) Standard for Wireless Network Devices - previous standards are A, B, & G. Each standard uses a certain frequency band for wireless radio broadcast, which is how a router or combination router/modem (know more commonly as the Access Point) connects to remote devices. Each device must have a wireless adapter conforming to the wireless frequency the access point is broadcasting on. Other 802.11 wireless standards are 802.11A (Wireless A), which is 5ghz; B & G are 2.4ghz. 802.11N is a combination overlapped frequency signal using both 2.4ghz and 5ghz. This combined frequency technique is called Multiple-In, Multiple-Out (MIMO) and is used for extended ranges and signal power at those ranges. The farther the range, the better the signal.

Where previous standards have only used one base frequency (5ghz or 2.4ghz, with minor settings off the base frequency available for individual setups so that it doesn't interfere with other devices like cordless phones) N uses both 5ghz and 2.4ghz for MIMO technology. As such, variant network devices using both N frequency bands (called Dual-Band N) allow the user to access and utilize both frequencies as if they were 2 separate devices. The advantage is that the user can transmit priority data (gaming, streaming media, business data, etc.) over one frequency, while regular networking data goes over the other, but without interfering with the other frequency band.

While Wireless N is still in Draft form, members of the IEEE also include engineers who work for the companies that develop networking devices: Linksys, D-Link, Netgear, etc. The reason that the N standard is being used on devices ahead of formal release is that those companies that developed it need to start getting an ROI to recoup the cost of that development, with the first devices being released in the summer of 2006.

The IEEE is expected to finalize the review of the draft standard and formally release it in 2009.

 

Google is your friend.

That ought to be the official NBR motto - "Google is your friend!"

 

when I got my N I could take my lappy all over my house. Before when I was on the g network the lappy would only go so far.

The N is a big difference. like 12 times more.
