Why Care About Wireless-N?
What wireless-N technology can do for your business?
It is projected that over the next three years, more than 1.3 billion wireless-enabled networked mobile devices will enter the marketplace. These mobile devices include net books, smart phones, notebook computers, tablet computers, and other devices. This explosion of wireless devices places more demand on the wireless network, which, in turn makes it essential to upgrade the network.
New services and applications, such as video conferencing, add to these bandwidth demands. Video-over-wireless devices, once perceived as consumer applications, have become established in the business environment as a way to reduce travel and training costs.
The adoption of mobile devices and video within the workplace illustrates the change in the way IT resources are being consumed, a trend that shows no sign of slowing down. Pervasive networks supporting a greater number of users and applications require a wireless network that can scale in performance by providing increased throughput, while at the same time delivering greater reliability and predictability.
The primary drivers for Wireless- N adoption include the following:
- An increasing number of users with varying needs require wireless connectivity. Small Businesses use their wireless networks to serve a wide variety of users with diverse needs – to connect employees in remote offices, provide the employees the freedom to work from anywhere and on any device. The increasing number of users is placing a greater demand on wireless networks, resulting in a need for higher throughput, along with greater reliability and predictability. Increasingly small businesses want to offer secure wireless guest access to suppliers, traveling employees or partners while they are on site.
- Availability of robust wireless security coupled with the need for mobility has led to a greater number of mission-critical applications being placed on the wireless network rather than just email and Internet access.
- Businesses are not tied to “desktops” any more and they must support an explosion of new mobile devices that require connectivity to the wireless network such as netbooks, smart phones, and tablet computers. In order to support these new devices businesses are looking for a next-generation wireless network that can provide the security and scalability to successfully support the mobile devices that users bring to work.
- Voice, data, and video are now converging on the wireless network. Businesses have recognized the benefits of using their WLANs for video and voice applications. As the technology for voice and video over WLAN has improved, the cost benefits of combining voice and video with data over one network has proved to be compelling for many small businesses. The WLAN must be designed to handle latency-sensitive multimedia applications, such as voice and video, while delivering reliable and predictable coverage.
How is wireless-N different?
The 802.11n standard delivers the bandwidth and reliability needed in today’s most demanding small business environments. Its support for interactive multimedia applications provides up to six times the performance of 802.11a/g networks.
The most noted improvement made possible through 802.11n is its ability to increase the throughput on a wireless network. In a typical deployment, businesses will see a noticeable increase of up to three to five times in the amount of bandwidth available per client. This increased bandwidth can help support bandwidth hungry applications such as video streaming and rich multi-media applications.
Reliability and Predictability
As the throughput enhancements of 802.11n enable small businesses to implement voice and video to improve and meet operational goals, reliability and predictability become more important. This is an area where 802.11n can truly offer breakthroughs in wireless networking. 802.11n uses multiple-input multiple-output (MIMO) signal processing that relies on multiple antennas and receivers to improve the reliability of the wireless link, decreasing the likelihood that packets will be dropped or lost thereby improving the link’s reliability, and ensuring more consistent throughput and predictable coverage at any point in your business environment.An added benefit of 802.11n is that it’s enhanced reliability and predictability extends to existing 802.11a/b/g clients in addition to new 802.11n clients.
