Outside of having the standard set of rules for WEP, WPA, WPA2, and WPS encryption modes, it adds a stronger security framework. Take the Asus RT-AC66R WiFi router, available in most stores for around $200 (the price you pay may vary from $295 down to $165).
This particular router does stateful packet inspection, detects denial of service attacks, provides access control, parental control, network service filter, URL filter, and a port filter. All of these security features have to be understood by the end-user, though, in order to be effective.
So why would the average user run out and buy one of these new devices? The answer is plain and simple and the same reason why so many people want a Bugatti over a Yugo–speed! Yes…the maximum theoretical speed of an older 802.11g wireless router is around 54Mbps. This is fast enough for most loading content from most web sites or to view streaming media over an Internet connection.
An 802.11N wireless router will get your data transferred over your home network’s connection at speeds around 100-150 Mbps throughput. To give you an example of how fast that is, consider downloading the latest drivers for your computer from the manufacturer’s website. There is a 250 MB file and your average download speed on the connecttion to the manufacturer’s FTP server is somewhere between 1-2 Mbps. If this were a straw being used to slurp down a shake, then think of it as you are using 1/64th of the straw for the shake and the other 63/64 parts are empty waiting for another shake, a soda, some beer, or whatever it is you wish to fill that up with.
That is one way of looking at bandwidth.
The reason why it is so much faster is that 802.11AC uses up to eight (8) MIMO (multiple in/multiple out) connections and each connection utilizes up to 180MHz per connection. Couple this capacity with using 256-QAM, a method for twisting the signals so that they can handle 256 different different signals that are being twisted/manipulated of each of these 256 streams and you come up with the capability of hitting close to 7Gbps bandwidth. To give you an idea of what that is, if you paid a small fortune and ran fiber optic data lines inside your home, you will be using close to 10Gbps and that is maximum theoretical speed.
If you home cable modem tops out at 20Mbps then that leaves a large amount of bandwidth of your network untouched. And since, right now, nothing inside your laptop, desktop, tablet or smart phone can come close to using all of that bandwidth, and given that the full potential of this technology has been touched, we have a ways to go before this is going to be incorporated in your computer or personal device.
Currently the Asus RT-AC66R is one of the fastest AC standard routers on the market and it tops out at speeds between 1300 and 1700 Mbps. This is a long way away from its maximum potential of 8 MIMO streams at 180MHz but instead it currently is using 4 MIMO streams at approximately 80 MHz for a combined total of 1750 Mbps. The limits now are the routers and the wireless cards in our computers and smart phones.
So do you need one of these devices? Maybe not now. Most of the best uses for this bandwidth will occur within the local network as the end user begins transferring video and photo files from one machine to another and the realization that what today takes 45 minutes to move will take approximately five minutes in the next two years or so. Right now, AC wireless cards are planning on being used in notebooks, desktops, and smart phones sometime in 2014 and 2015. So save your dimes, save your time and learn how to use a cable connection on your laptop to take advantage of the next to 3 Gbps data transfer speeds of a hard wired network connection.
