Abstract

A wireless local area network transmitting and receiving system includes a network driver interface, a random network layer, an infrastructure layer, a packet format conversion module and a distributed module. The packet format conversion module provides the wireless local area network with bridges to receive and convert wireless local area packets of the infrastructure layer, and then executes processes of transmitting and receiving the wireless local area network packets instructed by the network driver interface. The distribution module is connected to the infrastructure layer and the random network layer and then transmits the wireless local area network packets.

Claims

1. A wireless local area network packet transmitting and receiving system, comprising:

a network driver interface for receiving commands of activating actions;

a random network layer built inside the network driver interface for receiving and sending wireless packets within a transmission power of the network driver interface;

an infrastructure layer built inside the network driver interface for integrating wireless local area network packets from the random network layer to obtain an integrated packet;

a packet format conversion module disposed between the random network layer and the infrastructure layer for providing wireless local area network bridges receiving and converting the wireless local area network packets of the infrastructure layer, and then transmitting and receiving the wireless local area network packets according to instructions of the network driver interface; and

a distribution module disposed between the random network layer and the infrastructure layer and connected to the infrastructure layer and the random network layer for transmitting the wireless packets.

2. The wireless local area network packet transmitting and receiving system of claim 1, wherein the random network layer is connected with a workstation.

3. The wireless local area network packet transmitting and receiving system of claim 2, wherein after acquiring the integrated packet from the infrastructure layer corresponding to the workstation via the packet format conversion module that is connected with the workstation, the workstation is connected with another workstation via the distribution module corresponding to the workstation.

4. The wireless local area network packet transmitting and receiving system of claim 2, wherein the packet format conversion module is connected to a wireless local area network bridge.

5. The wireless local area network packet transmitting and receiving system of claim 4, wherein the distribution module is connected with the wireless local area network bridge of the packet format conversion module for exchanging wireless packets with the workstation that is connected with the random network layer.

6. The wireless local area network packet transmitting and receiving system of claim 2, wherein the workstation receives a signal from one selected from the group consisting of Internet, email, file transmission and a shared printer.

7. The wireless local area network packet transmitting and receiving system of claim 1, wherein the network driver interface further provides a wireless packet received by the packet format conversion module to a wireless compatibility certification unit, wherein the wireless compatibility certification unit certifies whether the wireless packet is compatible with and supports the wireless packet received by the local area network.

8. The wireless local area network packet transmitting and receiving system of claim 1, wherein the network driver interface is built inside one selected from a group consisting of a personal digital assistant (PDA), a personal computer and a notebook computer.

9. The wireless local area network packet transmitting and receiving system of claim 1, wherein the network driver interface comprises a switch module for enabling the network driver interface to switch to one of a station mode and a software Access Point base station mode.

10. The wireless local area network packet transmitting and receiving system of claim 1, wherein the network driver interface is further connected with a communication protocol.

11. The wireless local area network packet transmitting and receiving system of claim 1, wherein the infrastructure layer further integrates wired local area network packets from the random network layer.
