Through a WiFi bridge, it is possible to either connect two networks, expand the network coverage, and/or integrate devices with network interfaces into a network. Setting up a WiFi bridge is typically quick and easy, even for those less familiar with technology. Importantly, it eliminates the need for inconvenient cable laying between two buildings.
Connecting Two Networks with a WiFi Bridge
Connecting two networks can be achieved either through two access points or a router, which, in this case, takes on the role of an access point, and an access point in client mode. Special bridge components with exceptionally long-range and powerful integrated WiFi antennas are also commonly used, especially due to their weather resistance. In this case, the two access points or WiFi bridge components communicate exclusively with each other. This means that other devices such as smartphones and laptops can only access the respective other network through a separate access point. To set up a WiFi bridge, each of the two components requires its own IP address, and for security reasons, it is crucial to use secure WPA2 or even WPA3 encryption, which can be selected during configuration through the browser. Modern and high-quality devices offer what is known as Dual Band, meaning they can transmit on both the 2.4 GHz and the significantly less used 5 GHz frequency band. There are also devices that transmit in the 24GHz or 60GHz frequency bands. Under extremely favorable conditions, transmission rates of up to 2 GBit (Gigabit) are possible between devices from the same manufacturer, such as bridge components from Ubiquiti, Ligowave, or MikroTik.
Increasing Range
Linking two networks is not only practical for business use but can also have many advantages in universities or on larger private properties with multiple buildings. It allows for creating a unified and closed network where the involved devices can communicate well with each other. Additionally, only one router or internet connection is necessary. Under ideal conditions, large distances of up to 20 kilometers can be bridged. However, this assumes that there are no significant obstacles such as tall trees or thick walls between the two bridge components that interfere with signal transmission. A stable connection is still possible at distances below 250 meters, even with potential interference. To minimize obstacles, weather-resistant components can be installed outdoors. As a general rule, the higher the placement, the better, and the fewer obstacles between the components, the faster the connection.
Integration of Internet-Enabled Devices into a WiFi Network
While most everyday devices like smartphones and laptops typically rely on practical WiFi, for permanently installed devices like smart TVs or Blu-ray players, it may be beneficial to establish a LAN connection through the network interface. The advantage lies in both a more stable and faster connection, especially for transmitting large amounts of data, and lower power consumption (e.g., for Full-HD or 4K streams). Normally, these devices could be directly connected to the router. However, as the router is rarely placed directly next to these devices and usually has only four network ports, laying cumbersome cables and selecting which devices get a connection point would be necessary. This problem can be easily solved by using a WiFi access point in client mode. This access point can be placed directly next to the TV and securely connect to the existing WiFi network, then relay the internet signal to the TV via a network cable. Naturally, as with all other variants, attention should be paid to secure encryption with WPA2 or WPA3, even if there are only a few potential points of attack in a WiFi bridge.
The choice of devices and their intended purpose is entirely individual. However, the WiFi bridge offers many possibilities to increase range and integrate additional devices into an existing network. With the now available highly weather-resistant components, the signal can be networked over long distances.
