Tri-band Wireless Products on the Horizon

I'll stick to the wire. I don't like broadcasting to the neiborhood.



You can hide SSID from being visibly broadcasted, provided you use WPA/WPA2 with a strong password. Of course, it won't stop a determined hacker from discovering your hidden SSID except getting in, but it is enough to deter your casual neighbors from scanning your network.



I'd like to know what they plan on doing about the current inefficiencies of Wireless communication.


Currently, roughly half the bandwidth of a wireless LAN is immediately soaked up by packet meta-data, encryption information, routing information, etc, can currently consume 50% of an average wireless packet.


Second, as far as I'm aware current wireless technologies only provide an even division of bandwidth for each client, if you have 10 PC's then each PC gets alloted 1/10th the available bandwidth.


If you've ever wondered why a wireless LAN transfer can be as low as 2MB/s over a wireless N network, those are the biggest, along with inherent issues with wireless signals.


Even 7Gb/s would quickly be reduced to 350Mb/s if the above remains true with a 10 PC LAN. 



Well you might want to read up on wireless.  Wireless is a half duplex media.  So thus that is why you see half the bandwidth. 

Also wireless only transmitts one at a time it has to share the media.  It has protection mechanisms that help to prevent it.  So once you have the media and are transmitting you get the full bandwidth (although it is only half duplex).  So your 1/10th is wrong.  Now an access point generally will talk only as fast as the dumbest client.  Granted the more clients you have the longer it can take to get the all clear to transmitt from the access point.  So if you have a b client on a g network it slows everything down to b.  Now there are some protection protocols that can let the g transmitt somethings at higher levels, but other things have to be slowed down.  Which can also be why a N network will slow down.  Also as you get father away from an access point it will start to use dynamic rate selection and lower the bandwidth for the weaker signal.

So if all 10 of your clients are using the new 7 Gbs spec and everything is with in specs you would see around 437Mbs of throughput (if the bandwidth is 7Gbs).  But the article states a throughput of 7Gbs so that probably means the bandwidth is around 14Gbs, so you will see 7Gbs.

As for you thinking that overhead takes up 50% will your just wrong.  Certain encryption methods can take up some but it's no where near 50%. 



I'd love nothing more than the capacity to wireless everything in the home. I wish them well.  My only concerns are neighbor overlap, interference, and security.  Also, is there the possibility that the present unlicensed 60GHz frequency could later be licensed causing it's loss?


Either we conform the Truth to our desires or we conform our desires to the Truth.



Well the 60GHz band could be licensed just as easy as the ISM (2.4GHz) or UNII (5 GHz) bands used by wireless now.
