Wireless 802.11n Router
Dual Band and MIMO Technology
Wireless N router also known as “Draft-N Routers”, because their based on the 802.11n IEEE standard which has been revised now several times since January of 2007.
The Wireless N networking equipment you see in retail stores today are based on revisions from the 2007 802.11n standards and the amendments there after.
The current wireless N networking products selling today are not guaranteed to be fully compatible with future 802.11n products being released for sale.
802.11n has not yet been fully accepted as being an official final cut standard by the Institute of Electrical and Electronics Engineers (IEEE).
The IEEE is an association that operates in more then 160 countries around the world that is focused on the future and advancing innovative wireless networking products.
Wireless N Router
Whats new about N routers:
Wireless N network routers operate on the 802.11n draft standard, and was developed to combine earlier 802.11b and 802.11g standards, in an attempt to achieve much faster wireless connections over longer distances, as well as being able to avoid signal interference’s using “MIMO” and “Dual Band” technologies.
MIMO (Multi-In, Multi-Out) is a technology that operates using multiple internal antennas that are constantly monitoring your Wi-Fi network environment.
The MIMO technology feature continuously scans and looks for solid objects and signals being broadcast on interfering frequencies in close proximity to the router, and adjusts the wireless signal to compensate to maintain the best possible connection for your WiFi Devices.
Wireless N routers can also perform a newly released feature called “Dual Band”, meaning they can operate on both 2.4GHz and 5GHz frequency bands.
To put things in simple terms:
The 2.4GHz band has a further Wireless Router Range and can more easily pass through walls and solid objects, however each channel in the 2.4GHz ranges only uses 22MHz limiting the speed to a real world rate of about 11Mbps, although it advertises 54Mbps on the box.
The 2.4GHz frequency range also shares itself with many other technology products such as, cordless phones, microwave ovens, or a Bluetooth Receiver, which cause great signal interference in our ever crowded world of electronic devices.
The 5GHz band used with the newer MIMO technology utilizes 24 channels which are 40MHz wide providing much faster throughput of about 120Mbps real world, and by using multiple antennas can jump from channel to channel keeping the best possible signal for your wireless enabled devices.
The 5GHz signal range however is where it suffers operationally. Higher frequency range signals have a tighter frequency wave length making it difficult to pass through walls and solid objects limiting its range to the immediate area around the router.
How to use your wireless N router effectively:
For best performance you should connect all your multi-media and data streaming devices on the 5GHz band, and use the 2.4GHz band for everyday e-mail and surfing the Internet.
This will give your high bandwidth intensive equipment the room they need to operate smoothly without buffering and pausing.
Well, there you have it! That’s what is new about wireless N routers, until the next amendment to the 802.11n IEEE standard becomes available.
