Why we like wireless gear that utilize MIMO technology. MIMO stands for Multiple Input Multiple Output. MIMO multi-antenna technology yields significant performance improvements over the 802.11 standards. Full support for the existing a/b/g and additional standards allows for an unprecedented level of backwards compatibility and performance at all data rates. Providing full hardware support for Quality of Service [QoS] and government-grade security including Advanced Encryption Standard [AES] yielding maximum security and capacity. The only technology capable of easily connecting all video and music sources on a single high-speed, hassle free network.

One very important benefit is the [QoS —802.11e] Quality of Service capability built-into all properly implemented MIMO solutions that will actually prioritize important data on your local network for each participating user such as

Based on MIMO technology [3by3 configuration] a wireless LAN can accommodate latency-sensitive, bandwidth intensive multimedia applications such as HDTV streaming, provide the throughput-at-range for reliable coverage throughout a business or residence, and fully take advantage of increasing high-speed Internet connections. Users no longer have to be frustrated by slow connection speeds, spotty coverage or unreliable links.

Explicitly what differentiates MIMO from all other competitors is that it requires not only multiple antennas and radios on both the transmit and receive sides of the link but also the ability to do Spatial Multiplexing.

Spatial multiplexing allows for the transmission of multiple distinct datastream's over multiple radios in the same band at the same time, effectively doubling [or tripling] data throughput. Think of it as sipping water through two [or more] straws at once. Specifically, devices that exploite MIMO chipset and RF technology transmit two [2] distinct datastreams simultaneously at either 54M bit/sec to yield 108M bit/sec or utilizing chipset that includes MIMO technology producing 150M bit/sec for each datastream to yield 300M bit/sec.

Many wireless routers are only able to listen to one wireless signal at a time, the strongest one. If that signal is blocked or interfered with for example by a closing door, cordless phone, or your microwave oven, it can result in a wireless dead spot, cutting you off from your network. However, wireless routers utilizing properly implemented MIMO Technology are capable of listening to multiple signals simultaneously. So if any one of those signals is disrupted, the MIMO gear automatically maintains your network connection, eliminates dead spots and extends your range throughout your home or office.

[Key Point]Properly implemented MIMO systems divide a data stream into multiple unique streams, each of which is modulated and transmitted through a different radio-antenna chain at the same time in the same frequency channel. By taking advantage of multipath, reflections of the signals, each MIMO receive antenna-radio chain is a linear combination of the multiple transmitted data streams. The data streams are separated at the receiver using proprietary MIMO algorithms that rely on estimates of all channels between each transmitter and each receiver.

Each multipath route can be treated as a separate channel creating multiple "virtual wires" over which to transmit signals. MIMO employs multiple, spatially separated antennas to take advantage of these "virtual wires" created by multipath and transfer more data. In addition to multiplying throughput, range is increased because of an antenna diversity advantage, since each receive antenna has a measurement of each transmitted data stream.

With MIMO, the maximum data rate per channel grows linearly with the number of different data streams that are transmitted in the same channel.

A Properly implemented MIMO is Not a Typical Smart Antenna System
Typical one-dimensional smart antenna wireless systems sometimes use a combination of beam-forming to focus the transmitted signal energy, and receive combining or receive diversity to capture the strongest signal. Beam-forming may provide better range in certain applications, but serious issues include the creation of hidden nodes, a reduction in the number of clients that can be supported, and power consumption requirements that limit the number of transmit chains. In receive diversity solutions, the diversity antenna switches between multiple antennas to receive the strongest signal and improve reliability, but since there is no additional signal processing the quality of the signal remains the same. Similarly, while receive combining can process signals from multiple antennas to accommodate the affects of fading and multipath, neither technique increases data rates or capacity.

As everyone in your home/office begins to stream more video, download more MP3s, back-up and synchronize files on networked storage, play online games, and make more Internet phone calls - you place a greater demand on your home/office network. What you need is the speed to move content faster to everyone in your home/office without interruption and without wires.

Wireless routers utilizing properly implemented MIMO Technology can deliver wireless speeds as fast as your wired connection, up to 300 Mbps when combined with MIMO Network adapters —which gear incorporate MIMO technology. Properly implemented MIMO technology dynamically adapts to wireless interference to deliver the speed that your applications require on-demand. So whether you are streaming audio & video, uploading large files to your Storage Central, or just surfing the web, Wireless routers utilizing MIMO Technology delivers the speed you need when you need it. Now the performance and quality-of-experience once only associated with wired networks can be achieved in your wireless home/office.

Spatial Multiplexing is the KEY technology - simultaneously transmitting multiple unique data streams through the same radio channel, where MIMO multiplies the performance of a wireless device/network in the following ways:

• Multiplies speed to deliver high bandwidth applications such as streaming multimedia
• Multiplies coverage to provide a wider connectivity area with one access point or router
• Multiplies capacity to allow for more users on a single channel or network
• Multiplies reliability and puts an end to spotty coverage and user frustration
