Here, I take the H3C WA2600 + WX3024 802.11n wireless solution as an example to analyze the difficulties in deploying wireless networks.

1. high bandwidth, enabling users of the 11n and 11g to reach the highest rate at the same time.

The 802.11n protocol can reach a maximum speed of Mbps and has already exceeded the Ethernet speed of Mbps. Therefore, the 11n AP is upgraded to a Gigabit Ethernet port, the corresponding wireless switch must also be a gigabit interface. The WX3024 is such a gigabit wireless switch, ensuring no bottleneck for Mbps transmission. Based on the test results of a third-party professional evaluation organization, WA2600 + WX3024 can obtain an average application-layer bandwidth of about 150Mpbs, as shown in.

As we all know, although the 11n protocol can reach a maximum speed of mpbs and is backward compatible with 11a/g, there are not a few users of 11g, when 11n users and 11g users are connected to the single-frequency 11nAP at the same time, the rate of 11n users will be greatly reduced due to the same channel interference, and the high bandwidth features of 11n networks will not be able to be truly realized.

To avoid this problem, we recommend that you use the WA2620E (dual-band) + WX3024 Networking Mode for H3C. Because WA2620E can work both at GHz and 5 GHz, therefore, the GHz radio frequency can be reserved for 11G users, while the new 11n users use the 5 GHz band. In this way, users of the 11n and 11g are connected from two frequencies, and interference between them is completely eliminated. Users of the 11n and 11g can reach the highest rate.

Dual-band AP features high access density and low interference. The same is true for the 11n and 11g simultaneous access technologies described above, but it also brings high power consumption, this is very obvious in the 11n AP. Generally, the average single-frequency 11nAP power is around, and the dual-frequency power is at 16 W or larger, therefore, the traditional POE power supply method cannot be applied (15.4 W ). H3C WX3024 is a wireless switch that supports Gigabit POE +. Each port can provide up to 24 .5w power supply, providing stable and powerful energy support for high-performance APS such as WA2620E.

With the development of the network, wireless networks have been recognized by more and more users by virtue of the free and fast features, especially the 802.11n Technology (hereinafter referred to as 11n), with a connection rate of Mbps, this allows hundreds of megabytes of access over Ethernet, and supports a wide range of high-quality multimedia applications.

How to solve the above problems? Here, I take the H3C WA2600 + WX3024 802.11n wireless solution as an example to analyze the difficulties in deploying wireless networks.

3. Easy to manage, easy to maintain

How to configure a large number of APs, how to set rf, how to ensure the security of wireless networks, how to ensure AP load balancing, complex command lines, etc, these disturbing problems are scattered in the "H3C Small and Medium Enterprise 802.11n solutions.

WX3024 can collect all the AP information and automatically perform RF and Server Load balancer processing for users through intelligent computing. It also provides various AP configurations, including security and authentication, you do not need to configure each AP separately. You only need to click a few times on the WX3024 WEB configuration interface. In addition, H3C provides complete and various types of user operation guidance, making user management and maintenance easier.
