Wireless AP or wireless bridge for outdoor wireless coverage?

Some outdoor places, such as community parks, squares, etc., need to establish a wireless network, which requires the use of outdoor wireless devices, including wireless APs and wireless bridges. Many people are very entangled and do n’t know which one to choose, and they do n’t know if a wireless AP is better than a wireless bridge. In fact, both can be used!
As the name suggests, outdoor APs are APs used in outdoor environments. Compared with indoor APs, outdoor APs must be waterproof, moisture-proof, sun-proof, and freeze-proof, so they are generally sealed. Other aspects are similar to indoor APs, and basically can provide transmission rates of 150Mbps and 300Mbps.
A wireless bridge is a bridge of a wireless network. It uses wireless transmission to implement a bridge between two or more networks. It is slightly different from the working mode of AP. AP is equivalent to transforming a wired network into a wireless network, and a wireless bridge is a bridge connecting wireless networks.
They also differ in application. Wireless AP coverage can be used independently, and its users are mainly single mobile users, with functions such as roaming and authentication. Wireless bridges are mainly connections between user networks. Generally, they cannot be connected to the card and need to be used in pairs.
In addition, they have different transmission distances. Although an outdoor AP can also be used outdoors, its coverage area is circular, and the transmission distance is not particularly far, generally a few hundred meters to one thousand is very good. The wireless bridge can be used for long-distance transmission, generally up to 2-4 kilometers, and up to 10 kilometers if the antenna is used.
After reading the above, in fact, it should be very clear when to use an outdoor AP and when to use a wireless bridge. Generally speaking, if the range of outdoor wireless network is relatively small, then outdoor AP is sufficient. If the area is relatively large and long-distance directional transmission is needed, then use a wireless bridge.

Roller Shutter Profile Extrusion Dies

Aluminum alloy rolling shutter

Composition

Because the aluminum alloy of aluminum alloy roller shutters has low density but relatively high strength, which is close to or exceeds that of high-quality steel, aluminum alloy doors have good plasticity and can be processed into various profiles. They have excellent electrical conductivity, thermal conductivity and corrosion resistance, so they are widely used. Used in the door industry, its usage is second only to steel. Aluminum alloy rolling shutters are used in various places such as shops, high-end residential areas, commercial streets, corporate gates, anti-theft windows, bank entrances, etc. Aluminum alloy is the most widely used non-ferrous metal structural material. Anti-theft aluminum alloy rolling shutters can be repaired. Good anti-corrosion performance, after use, can significantly reduce the wear and noise during operation of rolling shutter doors and windows, and increase the service life of components.

Advantage

1. Safety

This product uses reversal technology when encountering obstacles. When it touches people, cars, etc., it will automatically reverse and return; ensuring the safety of the owner's body and property!

2. Strong

The door panel material is made of high-strength color steel imported from abroad. It is formed into one piece by special hydraulic work, and its strength is twice that of ordinary rolling shutters. The concave and convex parts are just tightly connected to each other, and the curvature is reduced by half!

3. Mute

Both sides of the rolling shutter door are made of special aluminum alloy, which has high strength, smooth trajectory, and the entire integrated door shape. There is almost no sound during use. In such an environment, the silencing rope is replaced, making it perfectly silent!

4. Beautiful

The appearance of the door piece is very three-dimensional and prominent, neatly arranged; the protruding part is of appropriate size, the motor is not exposed, and the whole is simple and beautiful!

5. Easy

It uses high-quality anti-fatigue torsion springs internally. Both sides rise and fall at the same time. It has good balance and long life!

6. Practical

Strong and durable, beautiful appearance, high strength, high toughness, corrosion-resistant aluminum alloy double (single) layer curtain, made of aluminum alloy, resistant to hits and scratches, blocking malicious intrusion from outside the door, and more effective security protection.

The appearance of the aluminum alloy rolling shutter door adopts electrostatic powder spraying process, which has strong weather resistance, anti-aging, rain resistance and corrosion resistance, and has a service life of more than 20 years.
