Description
Technical field
The utility model belongs to a kind of internet device, particularly relates to a kind of access device of local area network (LAN).
Background technology
As shown in Figure 1, in the communication of traditional wireless security protection, general this structure of employing.In Fig. 1, wireless front end (comprising wireless front end 1 ', wireless front end 2 ', wireless front end 3 ') is responsible for the collection of signal, and the information then will collected, sends to wireless receiving main frame 1 ' in a wireless form.Because wireless front end 1 ', wireless front end 2 ' distance wireless receiving main frame 1 ' is distant, exceed the maximum wireless communication distance of wireless front end 1 ', wireless front end 2 ' and wireless receiving main frame 1 ', therefore, need at wireless front end 1 ', between wireless front end 2 ' and wireless receiving main frame 1 ', increase a relay wireless signals 10 ', signal relaying relay meets communicating requirement.
This conventional wireless security protection communication shortcoming:
Transmission range is short: by the restriction of radio transmitted power and wireless receiving sensitivity, wireless front end is generally tens meters to the distance of wireless receiving main frame, after exceeding this distance, needs, between wireless front end and main frame, to add relay wireless signals.Even if increase signal relaying, communication distance is also can only in certain scope.
Easily be disturbed: due to the wireless security protection product of each producer, all use the frequency of national standard and transmitting power to carry out communication, be therefore easily subject to other wireless interference.Particularly especially outstanding when a large amount of use relay wireless signals in place.
The system integration is poor: existing scheme, is all generally that each place is used alone, cannot carries out the large-scale system integration and management.
As shown in Figure 2, in traditional wired security protection communication, generally this structure is all adopted.In Fig. 2, cable headend (comprise cable headend 1 ", cable headend 2 ", cable headend 3 ") be responsible for the collection of signal, the information then will collected, sends to cable network reception main frame 1 with wired forms ".Because cable headend 1 ", cable headend 2 " distance wired Receiving Host 1 " distant; exceeded cable headend 1 ", cable headend 2 " and cable network reception main frame 1 " maximum wire communication distance, therefore, need at cable headend 1 ", cable headend 2 " and cable network reception main frame 1 " between; increase a wire signal relaying 10 ", signal relaying relay meets communicating requirement.
This traditional wire security protection communication shortcoming:
Cost is high and affect attractive in appearance: between any one cable headend needing to use wire communication mode to cable network reception main frame, all need wiring.Not only increase the cost of system, and increase the difficulty of construction of system, also can affect the attractive in appearance of construction building.
Transmission range is short: the factor such as distributed constant, the line impedance impact being subject to wiring environment, wire rod, wired communication mode is also have limitation.
The system integration is poor: existing scheme, is all generally that each place is used alone, cannot carries out the large-scale system integration and management.
