Wireless communication Advantages and Disadvantages

Advantages of wireless communication: 

1.wireless communication network flexible, strong scalability; Wired communication networks do the opposite. Home decoration knows that if you want to cloth a room in the home, you must do a good job in the decoration. If the decoration is finished, it is very difficult to add network cables in a room. At this time, it can only achieve similar functions by wireless router + wireless network card. Similarly, almost all formal wired networks need to be designed, planned and constructed in advance, and are much less flexible and scalable than wireless networks. 

2.Wireless communication network construction cost is low, while wired communication network vice versa. Take the 3G/4G communication that everyone uses every day as an example. Operators can easily provide communication services for hundreds or even thousands of terminals by building a base station. Wireless communication can provide a lot of mobility, while wired communication is very weak. This one is easy to understand, right? 

Disadvantage of wireless communication: 

1.Wired communication bandwidth, and wireless communication network vice versa. Through the cable, you can achieve 10Gb/S rate; And through optical fiber, it can provide 400Gb/S. This is still out of reach for wireless communications. The quality of communication services provided by wired communications is usually more stable.

2.Wireless communication is limited by the communication medium and the service quality is weak. 

The above characteristics determine that wired communication technology is mostly used in the core network to realize the transmission and aggregation of communication services;The wireless communication technology is mostly used close to the client to achieve service access.
