Dual-frequency WiFi refers to the simultaneous transmission of 2.4g/5g band of dual-frequency terminal equipment. Double frequency. Maybe the users are still foggy about WiFi dual-band WiFi, and we're going to take you today to see what a dual-band WiFi is.
Let's start with a history of WiFi, the 1999 802.11a defines a physical layer with a data transfer rate of up to 54mbit/s on the 5GHz ISM band, 802.11B defines one on the 2.4GHz ISM ba

: Softap work in the wireless band, because the dual-frequency wireless network card supports both 2.4GHz and 5GHz, so when setting up the analog AP needs to choose the frequency of work. 2.4Ghz or 5Ghz can be selected under Windows XP system. Windows 7 system does not support the selection of frequency bands, the default work in the 2.4GHz band.

The 802.11AC standard is designed to provide high throughput in 5GHz bands, in addition to bringing fast, high-quality video streaming, and providing almost instantaneous data synchronization jobs and backups for laptops, tablets and mobile phones.
In theory, this specification will achieve at least 1gbit/s throughput of multiple-station WLANs and at least 500mbit/s maximum single link throughput. This is accomplished by expanding the concept of the

Analysis: This kind of standard implementation time is earlier, currently on the market still many wireless products only support to this Agreement standard scope. This type of product is characterized by "inexpensive", although the speed of support can only reach 11Mbps, but its affordable price for the initial wireless network users to reduce the threshold. Such products are already part of the transition "produc

Finally, small make up to you four piece of advice:
1. Upgrade your router device to a dual-band router that can support both 2.4GHz and 5GHz frequencies. It should be noted, however, that the 5GHz frequency signal has less wall-piercing capability than 2.4GHz, and that many older devices do not support this WiFi frequency.
2. Check the WiFi channel usage in the area th
to be considered. C in the 5GHz DFS channel, other signal transmitter (such as radar system) also need to take into account.
However, the problems caused by non-802.11 disturbances are more difficult to diagnose or avoid. When encountering such faults, the traditional approach is to use hand-held signal analyzer for sampling, this method has certain limitations. Scattered disturbances may not be transmitted at the time of sampling. In noisy high den
automatically choose the way to access the Internet (recommended)" This option does not recommend that you choose, because the router is sometimes not accurate identification, resulting in the wrong way to choose the Internet.
4. Choose Wireless Working frequency band:
Select: "Wireless work at the same time in the 2.4GHz and 5GHz band"--> "Next".

products, you should first choose 802.11a, 802.11b.
802.11B than 802.11a developed first, because the former uses relatively simple "sequential spread spectrum" technology, and 802.11A uses the "Orthogonal frequency Division Multiplexing" technology. Because the 802.11a technology to be more complex, and thus provide the data rate is very different: 802.11b working in the 2.4GHz band, speed can only reach 11mbps,802.11a work in the 5GHz band, the sp

But there are some notable differences between wireless network radios and other radios: They send signals at a frequency of 2.4GHz or 5GHz. This frequency is much higher than the frequency used for mobile phones, walkie-talkies and televisions. The higher the frequency, the more data the signal will carry. They use 802.11 network standards, spe

In the 90, experts from many companies worked together through the International Federation of IEEE, to develop new industry standards for the mutual connectivity of new wireless products. The Wi-Fi Alliance was born from this partnership and has a worldwide development test lab that detects whether products meet availability and safety standards.
