infrared transmission in the 2.4GHz ISM band, and the total data transmission rate is designed as 2mbit/s. Communication between the two devices can be done in a device to device (ad hoc) manner, or in coordination with the base station (base station, BS) or access point (Access Point,ap). In order to obtain good communication quality in different communication environment, the hardware communication mode of CSMA/CA (Carrier Sense Multi access/collision) is adopted.

The standard adopts OFDM modulation technology, there are "12" non-overlapping transmission channels, the transmission rate range is 6mbps-54mbps. However, this standard is incompatible with the IEEE802.11B standard.

: 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
