With the popularity of mobile Internet, wireless WiFi covers the trend of The Times, maybe you are just beginning to understand the wireless WiFi coverage, especially large and medium-sized wireless coverage, involving channel planning, same frequency interference, practical problems such as network latency, here are some basic knowledge about wireless WiFi coverage and faqs,
1, what is the same frequency interference
In wireless WiFi covers engineering, same frequency interference is a problem that can't avoid, same frequency interference is to point to if the same two AP work frequency, sending and receiving data would produce interference and delay at the same time,

2, wireless WiFi historical roots of the same frequency interference
In the place where WiFi design did not expect to be so popular, the original planning of the 11 channel, an area 11 wireless device is enough, but after the WiFi speed upgrade twice, a equipment used at the same time two or four channel transmission channel, thus causing the today's situation, a device USES 4 channel, two devices to be apart of 5 channel does not interfere with each other, which is 1,6,11 separated from each other, in an area can have only three wireless devices, apparently a bit less, prone to same frequency interference,

3, wireless WiFi channel should be how to plan
In wireless WiFi covers engineering, in order to reduce signal blind area, had to deploy multiple AP to complete wireless coverage overlap, pay attention to the reasonable planning and use of wireless channel, the adjacent AP press 1,6,11 separated from each other, on the left side of figure with frequency interference is serious, the right figure to improve some, wireless signal overlap will cause light frequency interference,

4, how to deploy wireless AP and channel optimization, to avoid the same frequency interference
To avoid the same frequency interference, the most efficient way to adjacent AP press 1,6,11 separated from each other, as far as possible the same channel spacing distance between the, mobile and telecom USES professional day feedback cover, industrial-strength wireless AP by 4 ~ 8 antenna feeder points, one AP to take up a channel covering a layer of floor or the whole building, effectively avoid the same frequency interference, as shown in figure, a layer with 1 channel, with 6 channels on the second floor, three layers with the channel, it won't produce the same frequency interference,

5, what is the impact of the wireless WiFi Shared frequency interference in a
Wireless network with frequency interference will cause the network packet loss and delay, become quite in the wireless network quality, speed becomes very slow, because the two AP work same frequency interference each other, leading to frequent repetition of sending data, the network used more frequently, the more serious the same frequency interference,

Day 6, feed type wireless WiFi covered walkway install
Day is recommended for large and medium-sized wireless WiFi covers engineering and feed type cover means, industrial-strength wireless AP by feeder points after four to eight antenna installed on the footpath, penetrates the cover on both sides of the room, day feedback WiFi is specialized in the way of cover, mobile and telecom covers the railway station, hotels, office buildings often use this way, the day feedback covering a layer of floor or the whole building can be done using a AP, facilitate the optimization of wireless channel, so use a layer 1 channel, with 6 channels on the second floor, third floor with 11 channel, to avoid the same frequency interference, walking the user in the past, are under the same AP, can reduce across AP switch, truly seamless roaming,

7 days feed type wireless WiFi coverage in install
For a relatively closed environment, wall cut off more places, corridor to install the wireless signal attenuation is bigger, can be used in installation, industrial-strength wireless AP points after 16 and 32 antenna, is made of super soft feeder into the house, the room beautify the antenna installation, such uniform coverage, no dead Angle,
