How to Survive and Thrive with 802.11n Wireless Networks

Wireless networking has become an essential part of modern life, but not all wireless technologies are created equal. If you want to enjoy the benefits of high-speed, reliable, and secure wireless connectivity, you need to know about 802.11n.

802.11n is the latest and most advanced standard for wireless LANs, offering a significant improvement over previous standards in terms of throughput, range, and compatibility. With 802.11n, you can achieve speeds up to 600 Mbps, cover larger areas with fewer access points, and support more devices on the same network.

But how do you plan, design, and deploy an 802.11n network that meets your needs and expectations How do you deal with the technical challenges and trade-offs involved in using this complex technology How do you ensure interoperability with older devices and standards

Fortunately, you don't have to figure it out on your own. You can learn from the experts who have already done it. One of them is Matthew Gast, the chair of the IEEE group that produced revision 802.11-2012, and the author of 802.11n: A Survival Guide, a concise and comprehensive book that covers everything you need to know about 802.11n.

In this book, you will discover:

How MIMO's multiple data streams greatly increase wireless speed

How 802.11n modifications improve MAC efficiency

How advanced PHY features such as beamforming and space-time code block enhance performance and reliability

How advanced MAC features such as aggregation and block acknowledgment reduce overhead and latency

How to plan an 802.11n network by determining traffic demand, key applications, power requirements, and security

How to choose the architecture, select hardware, and plan coverage to design and build your network

If you want to get the most out of your wireless network, you need to get 802.11n: A Survival Guide. You can download a free PDF version of the book from O'Reilly Media, or buy a print copy from your favorite online bookstore.

Don't let wireless networking be a source of frustration or confusion. Let 802.11n: A Survival Guide help you survive and thrive with 802.11n.

However, 802.11n also comes with some challenges and limitations that you need to be aware of before deploying it in your network. Here are some of the main ones:

Compatibility issues. Although 802.11n is backward-compatible with older standards, such as 802.11a/b/g, it may not work well with some legacy devices or applications that are not designed for high-speed wireless networks. For example, some older printers or scanners may have trouble connecting to 802.11n networks or may cause interference with other devices. You may need to upgrade or replace some of your existing equipment or software to ensure optimal performance and compatibility with 802.11n.

Interference and congestion. 802.11n operates in both the 2.4 GHz and 5 GHz frequency bands, which offer different advantages and disadvantages. The 2.4 GHz band is more widely used and has better range and penetration, but it is also more prone to interference from other devices, such as microwaves, cordless phones, Bluetooth devices, and other Wi-Fi networks. The 5 GHz band is less crowded and has more channels available, but it has shorter range and weaker signal strength, especially through walls and other obstacles. You may need to carefully plan your channel selection and placement of your access points to avoid interference and congestion in both bands.

Power consumption and heat dissipation. 802.11n devices consume more power and generate more heat than previous standards, due to the increased processing and transmission requirements. This may affect the battery life and performance of your wireless devices, especially laptops and smartphones. You may need to adjust your power settings and cooling systems to ensure your devices can handle the increased workload and temperature.

Despite these challenges, 802.11n offers many benefits that outweigh its drawbacks for most users and scenarios. If you want to enjoy faster, more reliable, and more secure wireless networking, you should consider upgrading to 802.11n as soon as possible. ec8f644aee
