Description
Technical field
The present invention relates to Wireless Laser Communication Technology field, more particularly to a kind of wireless laser communication equipment.
Background technology
The communication technology has greatly promoted the development of society, revolutionizes the life style of people.Communication has become dimension
Hold the information main artery that entire society's ecosystem runs well.Existing means of communication cannot meet the fast of mobile terminal
The demand of speed popularization and mobile subscriber to mobile communications network each side, is mainly manifested in：
1. to the demand of two-forty
For user, the higher the better for traffic rate, but being significantly increased with mobile subscriber's quantity, meeting user
On the premise of high rate communication, bigger communication channel bandwidth is needed, and existing Mobile communication bandwidth is already close to theory
The limit, it is clear that it is difficult to while meet the communication requirement of multi-user's two-forty.
2. to the demand of coverage
Due to technical difficulty or construction cost problem, the quantity of microwave base station is also not enough to cover all regions, because
Even if this existing mobile communications network also has substantial amounts of blind area in city, cannot receive in these area's intra domain users
Movable signal.Can significantly weaken movable signal intensity additionally, due to the blocking of building, geographical position factor, weather reason etc.,
Low signal areas are caused, can show to receive the phenomenons such as jitter, speech quality difference in that region.And ocean,
Desert, mountain area and outlying district etc. then cover without mobile communications network.
3. to the demand of economy
Existing internet and mobile communications network, construction cost is high, maintenance difficult, and maintenance cost is high, capability to resist destruction
Difference, takes resource greatly, result in the use cost height that communication network is there is in terms of economy, and communicating, efficiency-cost ratio is low to ask
Topic.
4. to the demand of security
To ensure that the information transmitted on network is not trapped as far as possible, it is ensured that network is not by from extraneous unauthorized access
And attack, it is ensured that the safety of stored information on personal terminal.Due to the opening of mobile telecommunication channel so that law-breaker holds
Movable signal is easily intercepted and captured, so as to steal user's key message.
5. to the demand of the communication mode of environmental protection.
Ensure that adopted means of communication reduces as far as possible electromagnetic radiation, in case harm people's is healthy.In addition,
Also energy loss is reduced as far as while communication requirement is met.And there is electromagnetic pollution in existing means of communication, energy
Consumption is big, because rather than environmental protection communication mode.
In order to solve the problems, such as traffic rate, country is carrying forward vigorously the research and construction of 5G networks.But 5G networks
Still it is built upon with the communication technology on radio communication and Basis of Fibre Optical Communication, although traffic rate is improved, but
Cannot fundamentally solve the problems, such as that traffic rate is low.Safety issue existing for 4G networks, 5G networks are still present.Compare
4G networks, the base station of 5G networkings will be more, and construction cost is higher.In addition, 5G networks still cannot be realized to ocean, sand
Unconcerned and backwoodsman covering.2G, 3G and 4G network base station is built, and typically all away from residential block, and 5G networks will be built in a large number
If the little base station of low-power, base station deployment density will be more than 10 times of 4G base stations, and electromagnetic pollution problem, the problem of pseudo-base station will
Become more to project.
