A method for transmitting and receiving a message is provided. The method includes steps of providing a bridge device having a bridge hardware address and a first end, receiving a first message including a first hardware address, a first protocol address and a second protocol address from the first end, recording the first hardware address and the first protocol address on a table, replacing the first hardware address with the bridge hardware address, transmitting the first message to a second end having a second hardware address corresponding to the second protocol address; transmitting a second message including the first protocol address, the second protocol address, the bridge hardware address, and the second hardware address from the second end to the bridge device, replacing the bridge hardware address with the first hardware address according to the table; and transmitting the second message to the first end.

A load balancing method for a wireless local area network (LAN) which has a plurality of access points is provided in the present invention. The load balancing decision is made by a load balancing module according to traffic conditions and bandwidth availability of each traffic priority class based on a corresponding class of service. The load balancing module is a centralized module which the load balancing decision is determined by the centralized module, or is determined through information exchanges among distributed load balancing modules of the access points. The load balancing decision also takes into consideration of VLANs per VLAN tag basis. Each of the VLANs is defined with the corresponding traffic priority class.

QoS based load-balance policy for WLAN

A multiple frequency band planar antenna formed on one-side surface of a circuit board comprises: a first antenna pattern, a second antenna pattern, a third antenna pattern and a fourth antenna pattern, each antenna pattern further comprising an elongated portion and a conductor portion; wherein the second elongated portion at a point between its two ends is short-circuited to a feeding transmission line formed on another-side surface of the circuit board through a via. Thus, the multiple frequency band planar antenna can operate at three frequency bands with their central frequencies at 2.4 GHz, 3.5 GHz and 5.8 GHz, respectively, suitable for both WIFi LAN and WiMAX MAN applications.
