Abstract: A method for generating a prompt message for network connection conversion and a network system thereof are provided. The system can be a LAN with multiple access points (APs). The method is operated in a root AP. The root AP receives a connection conversion command from a user device, in which a target AP is designated. The root AP determines at least one AP that is available to be connected with the target AP based on an instant wireless signal strength there-between. After that, the target AP obtains at least one connection rates from the target AP to the root AP via the at least one available APs. The root AP generates a prompt message for connection conversion according to the connection rates. A topology map displayed on the user device can be used to indicate the available APs for the connection conversion.

Abstract: Methods and apparatus are disclosed for data packetizing in an orthogonal frequency division multiplexing (OFDM) system. In order to improve transmission efficiency, the present invention uses independent packet and OFDDM block boundaries. Therefore, a packet is allowed to go across the OFDM block boundary and packed into two OFDM blocks. To indicate the start of each packet, a Frame Delimiter (FD) with a predefined format is inserted in front of each packet. The predefined format of the FD can be a predefined bit pattern or modulation points of modulation constellation. Idle data can also be inserted into OFDM blocks when no packet is ready. When data of one or more packets and idle data contain the predefined bit pattern of the FD, the data are modified to avoid generating the pre-defined bit pattern.
