Type, frequency band and purchase advice of wireless bridge

As an important wireless communication technology, wireless bridge plays a key role in industrial Internet of Things and many networking applications. It uses RF signals to achieve long-distance and efficient network connections, especially for environments where wired networks are inconvenient or impossible to lay. The following is a professional explanation of the types, frequency band selection, and purchase recommendations for wireless bridges.

1. Types of Wireless Bridge

Wireless bridges are mainly divided into the following types according to their application scenarios and connection methods:

Point-to-point type: This type is commonly used for network connections between two fixed locations and is a common method of wireless networking. Its advantages are long transmission distance, high transmission rate, and less influence from external environment.

Point-to-multipoint type: This type is suitable for situations where there is a central point and multiple remote points. Its biggest advantage is that the cost of setting up a network is low and maintenance is simple. At the same time, the center uses omnidirectional antennas, making equipment debugging relatively easy.

Hybrid: Hybrid wireless bridges are suitable for networks with long-distance points, short-distance points, and points blocked by buildings or mountains. It integrates the use of point-to-point and point-to-multipoint connection methods to achieve optimal network coverage and transmission efficiency.

2. Frequency band selection

The selection of frequency band for wireless bridge is crucial to its performance. Common frequency bands are 2.4GHz and 5.8GHz:

2.4GHz band: This band is widely used, but it is susceptible to interference from other wireless devices, such as microwave ovens and Bluetooth devices. Therefore, in environments with significant interference, it may be necessary to consider other frequency bands.

5.8GHz band: This band has strong anti-interference capability and is more suitable for long-distance transmission. However, its penetration ability is relatively weak, so it may not perform well in environments with obstacles.
When selecting a frequency band, it is necessary to consider factors such as specific application scenarios, environmental interference, and transmission distance.

3. Suggestions for Purchasing

Clear functional requirements: When purchasing a wireless bridge, it is important to first clarify its main functional requirements, such as whether it supports wireless security encryption, whether it supports multiple network protocols, and whether it supports reliable data transmission. These functions will directly affect the performance and applicability of the wireless bridge.

Understanding performance parameters: signal transmission rate, wireless network transmission distance, number of connectable devices, and security encryption level are important factors to consider when purchasing a wireless bridge. Select equipment with appropriate performance parameters according to actual needs to ensure the stability and reliability of the network.

Choose a reputable brand: When purchasing a wireless bridge, opt for a reputable brand and manufacturer to ensure product quality and after-sales service. Established brands typically have more comprehensive warranty policies and technical support, which can provide users with a better experience.

Consider cost-effectiveness: The price of wireless bridges varies depending on factors such as brand and performance. When shopping, you should consider comprehensively based on your actual needs and budget, and choose a product with high cost performance. At the same time, we should pay attention to avoid sacrificing performance and quality in the blind pursuit of low prices.

Pay attention to installation and maintenance: The installation location and method of the wireless bridge have a great impact on its performance. During installation, an open line-of-sight location should be selected to reduce signal attenuation and improve network transmission efficiency. In addition, the performance parameters of the wireless bridge should be checked regularly, and problems should be found and maintained in time to ensure the normal operation of the network.

The type, frequency band selection, and purchase recommendations of wireless bridges are all key factors that affect their performance and application effectiveness. When purchasing and using a wireless bridge, various factors should be considered to ensure the stability and reliability of the network and meet the network requirements of various environments.
