Description of drawings:

Fig. 2 is a right view of the directional signal booster shown in Fig. 1 .

Detailed ways:

Embodiment: See Fig. 1 and Fig. 2, among the figure, 1-wireless router, 2-antenna, 3-fastening pad, 4-metal barrel, 5-direction seam.

The method for reducing the wireless network drop rate is characterized in that it may further comprise the steps:

1. Solve the conflict between the channels used by wireless devices: the commonly used IEEE 802.11b/g works in the 2.4-2.4835GHz frequency band, and these frequency bands are divided into 11 or 13 channels. If two or more wireless devices use one channel for communication at the same time , it may cause bandwidth congestion or mutual interference, resulting in dropped calls. The IEEE802.11b/g standard only supports 3 non-overlapping transmission channels, only channels 1, 6, 11 or 13 are non-conflicting, but devices using channel 3 will interfere with 1 and 6, devices using channel 9 Will interfere with 6 and 13. The solution is to change to an uncommonly used wireless channel in the wireless router setting interface, and use different channels 1, 6, and 11 to reduce conflicts. After investigation, the wireless Internet terminals in each department with wireless coverage are regularly divided, so that channels 1, 6, and 11 are reasonably allocated to each wireless coverage area. Adjust the configuration to place three wireless routers on each floor, and set their channels to 1/6/11 respectively, which terminal wants to connect to which device, set it to the channel of the corresponding wireless device.

2. Increase the signal coverage area of wireless devices: adjust the position of the device, and install an omnidirectional antenna if necessary. Although the coverage distance in the direction of the main lobe of the mechanical antenna changes significantly, the amplitudes of the vertical and horizontal components of the antenna remain unchanged, so the antenna pattern easily transformed. In the vertical pattern, it is shown as a beam with a certain width. Like an omnidirectional antenna, the smaller the beam width, the greater the gain. Omnidirectional antennas are suitable for office areas with a wide coverage area but low application density.

3. Improve the signal strength of wireless devices: the signal attenuation in some specific directions or after passing through walls is very rapid, for example, after passing through two walls, the signal attenuation is 60% of the original signal. A directional signal enhancement device is installed on the router antenna to strengthen the wireless Internet access terminal equipment that can be reached in a special direction and needs to pass through the wall. On the horizontal pattern, it shows radiation in a certain angle range, which is commonly referred to as directional. In the vertical pattern, it is shown as a beam with a certain width. Like an omnidirectional antenna, the smaller the beam width, the greater the gain.

The directional signal enhancement device includes a metal barrel 4, and the bottom of the metal barrel 4 is provided with a through hole, wherein: the barrel wall of the metal barrel 4 is provided with a strip-shaped directional seam 5, and the directional seam 5 is arranged along the axial direction of the metal barrel 4 A fastening mechanism is provided between the bottom of the metal bucket 4 and the antenna 2 of the wireless router 1 .

The fastening mechanism is a rubber-type fastening pad 3, and the fastening pad 3 is set in the through hole, and the ring-shaped groove on the outer surface of the fastening pad 3 is stuck on the bottom of the bucket, and the antenna 2 is connected from the fastening pad 3. It passes through the center hole and is a tight fit between the two.

Another kind of fastening mechanism can also be used, the fastening mechanism is a positioning sleeve and a screw, the positioning sleeve is clamped on the through hole, the antenna passes through the center hole of the fastening sleeve pad and there is a clearance fit between the two, and the screw The inner end penetrates the positioning sleeve radially and contacts the antenna. The screw is made of plastic and has a rounded head at the end to avoid damage to the antenna.

The metal barrel 4 can be made by cutting waste cans, and one or two devices can be made from one can, which saves cost.

When in use, put the metal barrel 4 on the antenna 2, turn the metal barrel 4, make the directional seam 5 face a specific direction, and then use the fastening mechanism to make the metal barrel 4 and the antenna 2 relatively fixed, easy to adjust, and ensure a specific direction wireless signal.

The above is only a preferred embodiment of the present invention, and does not limit the present invention in any form. Any simple modification made according to the technical essence of the present invention still falls within the scope of the technical solution of the present invention. the
