Difference between microwave wireless transmission system and WIFI transmission and 4G transmission
With the increasing use of wireless surveillance in the security field, more and more projects are adopting wireless monitoring methods because of the inconvenience of wiring. For some environmental impacts, such as renovated interiors, long-distance transmission of sea transmission, construction site video surveillance, etc., all conditions are allowed to use wireless monitoring.
The main part of the wireless monitoring system is the transmission part. Wireless transmission is divided into WiFi, 3/4G wireless network transmission and microwave transmission. What are the advantages and disadvantages of these transmission methods? What is the applicable environment? Let's talk about it in the following small series.
First, 4G wireless monitoring equipment
4G wireless monitoring is a remote wireless monitoring system that can be used as long as 4G network is available. It adopts the most XIN 4G communication technology and is designed to achieve a simple installation for home, small business or industry-specific user monitoring applications. A flexible and cost-effective 4G mobile video surveillance device.
Advantages: As long as there is coverage of the 4G signal, the device can be transmitted by transmitting the signal. Flexible operation, simple installation, and not limited by environmental distance. The upfront investment is very low and can be monitored anytime, anywhere.
Disadvantages: Because this monitoring method will involve traffic problems, the later traffic consumption is also very amazing, not suitable for long-term 24-hour monitoring. Only suitable for temporary use in some special industries.
Second, WIFI wireless monitoring equipment
WIFI is something we are all familiar with and can't live without. Now our first machine, computer, ipad, the most inseparable thing every day is the wireless network signal. The coverage of WIFI can reach about 1 km in an open environment, not to mention the office and the home. WIFI frequency band is a free frequency band without any telecom operation license worldwide, so WLAN wireless equipment provides a world. A wireless air interface that can be used in the range and is extremely inexpensive and has a very high data bandwidth.
Advantages: The investment cost is very low, the installation is very convenient, and the network can be built without professionals.
Disadvantages: The transmission distance is close, and the signal can only be transmitted in close proximity indoors, and the diffractive ability is also very poor. When the signal is transmitted, the obstruction is avoided as much as possible.
Third, microwave wireless monitoring equipment
Microwave wireless monitoring is the perfect combination of microwave technology and wireless monitoring technology. Microwave wireless monitoring can be divided into analog microwave and digital microwave. A typical representative device is a wireless bridge. Now basically analog microwave has gradually withdrawn from the historical stage, digital microwaves occupy the main market.
Digital microwave transmission is wireless bridge transmission. As the name suggests, wireless bridges are the bridges of wireless networks. They use wireless transmission to bridge the communication between two or more networks. Wireless bridges can be used in point-to-point transmission, point-to-multipoint, or medium. Following the way.
Advantages: low cost, easy installation, no wiring, short construction period. It plays a big role in various monitoring. In the construction site wireless monitoring system, maritime wireless monitoring system, oil field wireless monitoring, forest fire wireless monitoring, tunnel wireless monitoring, river wireless monitoring system ... can be used in almost every industry. Easy to install, easy to use, no complicated debugging, and easy maintenance.
Disadvantages: There are requirements for the environment. The request is in an open environment. There can be no occlusion.
The three wireless monitoring transmission methods are all good and bad, and can't say who is good or who is not good. It depends on the specific application environment. Have a clear understanding of the environment before making a choice. Then decide according to the needs. Bmw Carbon Fiber Steering Wheel
