Description of drawings

Fig. 1 is an overall structure schematic diagram of the present utility model.

Embodiment

The utility model is described in further detail below in conjunction with embodiment, but execution mode of the present utility model is not limited thereto.

Embodiment

As shown in Figure 1, feed-type small-size wireless terminal of the present utility model is made up of wireless module 1, Switching Module 2, AC/DC module 3, first ethernet port 4 and second ethernet port 5.Wherein, first ethernet port 4 is used for being connected with user side, according to actual conditions, this user side is divided into wire user end, wireless user end or integrated wired and wirelessly be three kinds of situations of user side of one, the wire user end is connected with first ethernet port 4 by the Ethernet data line, wireless user's end then is connected with wireless module 1 by the Wi-Fi technology, to guarantee that this wireless module 1 can set up data with wireless user end and be connected (the WLAN (wireless local area network) access promptly is provided), Switching Module 2 then is used for carrying out exchanges data with this wireless module 1.

In order to realize the utility model, this wireless module 1 needs to support the IEEE802.11a/b/g/n agreement.As required, wireless module of the present utility model 1 is concrete supports a kind of in IEEE802.11a agreement, IEEE802.11b agreement, IEEE802.11g agreement, IEEE802.11n agreement, IEEE802.11a/b agreement, IEEE802.11a/g agreement, IEEE802.11a/n agreement, IEEE802.11b/g agreement, IEEE802.11b/n agreement, IEEE802.11a/b/g agreement, IEEE802.11a/b/n agreement, IEEE802.11a/b/n agreement, IEEE802.11b/g/n agreement and the IEEE802.11a/b/g/n agreement.Simultaneously, because the utility model also needs to realize the Wi-Fi function, wireless module 1 preferential AR9285 module or other modules with identical function of supporting the IEEE802.11a/b/g/n agreement that adopt therefore of the present utility model, Switching Module 2 then adopts the Switching Module of embedded central processing unit.Perhaps as required, this central processing unit is positioned at the outside of Switching Module 2 as an individual devices, and is connected with this Switching Module 2.

In order to ensure effect, described central processing unit preferentially adopts MIPS processor or arm processor, and described Switching Module 2 preferential employings can be supported the AR7240 module of 5 switching ports.AC/DC module 3 is common AC-DC electric pressure converter, during connection, this AC/DC module 3 is connected with Switching Module 2 with wireless module 1 respectively, and convert the alternating voltage of outside 220V to be complementary direct-current working volts with wireless module 1 and Switching Module 2, to guarantee that this wireless module 1 and Switching Module 2 can operate as normal.Simultaneously, Switching Module 2 also is connected with second ethernet port 5 with first ethernet port 4 respectively.

Ethernet port power receiving equipment (i.e. upper end cascade device) is connected with second ethernet port 5 of the present utility model by the Ethernet data line, the wire user end is connected with first ethernet port 4 by the Ethernet data line, wherein said ethernet port power receiving equipment is the access network equipment with Ethernet interface, for example can be port powering type Ethernet switch or port powering type ONU (Optical Network Unit, optical node) or the like.During use, AC/DC module 3 converts the 220V alternating voltage that the outside connect to the direct-current working volts of the needed 36V of ethernet port power receiving equipment, 48V or 72V, and this voltage is input on second ethernet port 5, utilize the Ethernet data line to provide operating voltage at last for the ethernet port power receiving equipment.

Implementation method of the present utility model is: at first convert the alternating voltage of outside 220V the operating voltage of wireless module 1 and Switching Module 2 to by AC/DC module 3, to guarantee that wireless module 1 and Switching Module 2 can operate as normal.Simultaneously, this AC/DC module 3 is also exported the required operating voltage of ethernet port power receiving equipment of upper end in second ethernet port 5.

Then, second ethernet port 5 operating voltage that this ethernet port power receiving equipment is required is right through 1,2,3,6 lines of Ethernet data line, or 4,5,7,8 line right, or 1,2,3,6 and 4,5,7,8 line to being input to the ethernet port power receiving equipment, and start this ethernet port power receiving equipment simultaneously and set up data with it and connect.

At last, judge whether user side has the Wi-Fi function.Has the Wi-Fi function if judge this user side, then this user side is connected by setting up wireless data between Wi-Fi technology and the wireless module 1, after the authentication of upper end, this wireless user's end is by carrying out exchanges data and transmission between Wi-Fi network and the wireless module 1.

If this user side does not have the Wi-Fi function, judge again then whether this user side has ethernet port.If ethernet port is arranged, promptly this user side just has the common wire user end of ethernet port, and then second ethernet port 5 data-signal that will be obtained from the ethernet port power receiving equipment carries out exchanges data by wired mode and this user side behind the Switching Module 2 and first ethernet port 4.If this user side does not have ethernet port, then do not carry out any action.

Wherein, when judging whether user side has the Wi-Fi function, its flow process is as follows: at first pass through wireless medium by user side, and send connection request; Receive this connection request by the wireless module in the feed-type small-size wireless terminal 1 then, and connect by IEEE802.11a/b/g/n agreement and user side, audit sends request; At last, if the audit of user side is passed through, assert that then this user side has the Wi-Fi function, and set up the network that meets the IEEE802.11a/b/g/n agreement, this user side then inserts this network by Wi-Fi; If the wireless terminal audit is not passed through, then be considered as illegal request, assert that this user side does not have the Wi-Fi function, will not connect.

As mentioned above, just can well realize the utility model.
