How to Build a High Performance and Secured Network

The best wireless network should consist of wireless devices and wireless standards which can provide the best technologies in three main areas: the fastest wireless network technology, the farthest network coverage, and the most secured network.

If you would like to build a wireless network from the scratch, it is recommended to use the best wireless network based devices, using the current wireless technologies available at the marketplace today.

The best wireless network should consist of wireless devices and wireless standards which can provide the best technologies in three main areas. Firstly, the wireless devices and standards should provide the fastest wireless network. Secondly, wireless devices and technology used should provide the farthest network coverage. Thirdly, the wireless security standard should provide the most secured network to protect the private network against any types of network threats.

The Best Wireless Network in Speed

The fastest and the best wireless network available at the market today is draft 2.0 802.11n standards. This is the latest industrial standards today – the future technology, but it is still not ratified yet. Even though it is not finalized yet, mostly all the wireless manufacturers ship their lines of wireless products based on this draft standards. The recent manufacturers ship their products and claimed that the wireless network can provide the speed up to 300 Mbps. However, this is all theoretical, in a sense, due to the fact that routers never achieve the maximum throughput they’re rated at (802.11b at 11 Mbps and 802.11g at 54 Mbps).

Wireless -n router is not guaranteed to work with the final 802.11n standard when it arrives in another year or so. Why, then, should you invest in pre-release technology with iffy chances of operability in the future? Because, this draft version is assured to be backward compatibility with the current industrial standards 802.11b and wireless 802.11g wireless devices, and can be used to fill in the gaps of your wireless network today. Besides, when the draft 802.11n has been ratified officially as the fastest wireless industrial standards, it is widely believed that there will be no hardware changes. The only thing you need to upgrade is the firmware that will be freely downloaded from the official vendor’s websites. Even some vendors design their products with the capability of download the recent firmware automatically when it connects to the internet.

The Best Wireless Network in Network Coverage

Selecting the best wireless network should provide the technology with the farthest network coverage. A current technology widely adopted by the manufacturers to provide the farther wireless network coverage is the combination of wireless -N and Multiple-in-multiple-out (MIMO) antenna technology. MIMO uses multiple transmitter and receiver antennas to improve the system performance. MIMO technology relies on multipath signals. Multipath signals are the reflected signals arriving at the receiver some time after the line of sight (LOS) signal transmission has been received. MIMO technology combined with the wireless -N creates robust signals for maximum range and speed with reduced dead spots.

Some manufacturers embedded their product with their own competitive technology for better network coverage. For example D-Link introduces Extreme -N technology to provide the speed up to 14x faster and provide 6x the range farther when compared to 802.11g wireless devices.

The Best Wireless Network in Security

Selecting the best wireless network, you should think about the best security the network can protect against any threats. As a general rule, you should employ a level of security that corresponds to the sensitivity of the data on your network. Unlike wired systems, which can be physically secured, wireless networks are not confined to the inside of buildings. They can be picked up as far as 1,000 feet outside of the premises with a laptop and a gain antenna. This makes WLANs inherently vulnerable to interception.

The latest industrial wireless security standard is WPA2. WPA stands for Wi-Fi Protected Access which is a certification program created by the Wi-Fi Alliance to indicate compliance with the security protocol created by the Wi-Fi Alliance to secure wireless computer networks. This protocol was created in response to several serious weaknesses researchers had found in the previous system, Wired Equivalent Privacy (WEP).

The other features you should consider in selecting the wireless devices for the best wireless network is the Quality of Services (QoS) feature which capable of providing the prioritization of the data stream.

With wireless routers (without the QoS feature), all wired and wireless traffic, including VoIP, Video Streaming, Online Gaming, and Web browsing are mixed together into a single data stream. By handling data this way, applications like video streaming could pause or delay. With Intelligent QoS Technology, wired and wireless traffic is analyzed and separated into multiple data streams. These streams are then categorized by sensitivity to delay, so applications like VoIP, Video Streaming, and Online Gaming are given priority over Web browsing. This enables multiple applications to stream smoothly to your TV or PC.

D-Link introduces Gamer Lounge DGL-4500 with intelligent QoS technology which is designed specifically for gamers in mind.

The last but not the least for the best wireless network you can also consider the dual-band feature of the wireless access point and also the wireless clients. With the dual band technology, the wireless devices support 2.4GHz & 5GHz wireless signals at the same time. This allows you to check e-mail and browse the Internet using the 2.4GHz band while simultaneously streaming High-Definition (HD) movies and other media on the 5GHz band.

With the best wireless network, it is not perfect if you do not deploy the antivirus software for each of the computers on the network. See also the Internet threats and antivirus software.
