Abstract: A method for wireless channel frequency hopping synchronization in a PLC-RF integrated network having a first node, a second node, at least one PLC media and a RF media includes one of following characteristics: the first node uses the PLC media to transmit first frequency hopping data, and the second node receives the first frequency hopping data and then uses the first frequency hopping data to transmit or receive a packet on the RF media; the first node uses the PLC media to transmit second frequency hopping data, and the second node receives the second frequency hopping data and then transmits the second frequency hopping data on the PLC media; and the first node uses the RF media to transmit third frequency hopping data, and the second node receives the third frequency hopping data and then transmits the third frequency hopping data on the PLC media.

Abstract: The invention provides a data transfer method of a hierarchical 6LoWPAN mesh network. The hierarchical 6LoWPAN mesh network includes an application server and a NGW storing a routing table and a tunnel table, and has a level 1 mesh network and a level 2 mesh network. The method includes: a data transmitting step, in which a packet of the level 2 mesh network is transmitted on a 6LoWPAN leaf node of the level 1 mesh network through a tunnel between L1_6LN and NGW, wherein the tunnel is used to perform uplink transfer or downlink transfer between the L1_6LN and the NGW.

Abstract: A method for processing a network packet is used for a routing apparatus. The routing apparatus includes a forwarding engine module and a core module. In the method, a network packet from a source interface is received. Whether or not the network packet meets a Network Address Translation (NAT) packet condition is determined. Subsequently, the following steps are executed when the network packet meets the NAT packet condition. In these steps, transmission information of the network packet is read and a NAT mapping table is searched by using the transmission information. When a mapping entry corresponding to the transmission information is found in the NAT mapping table, the method involves enabling the forwarding engine module to update the header of the network packet according to the NAT forwarding information of the corresponding mapping entry and set a destination interface of the network packet.

Abstract: A Base Station (BS) communication module and a Customer Premise Equipment (CPE) communication module are adapted to implement a method for selecting a Modulation and Coding Scheme (MCS). The method for selecting an MCS includes the following steps: receiving a plurality of first packets in a first period, and calculating a Packet Error Rate (PER); determining whether the PER is greater than an error rate threshold; and when the PER is greater than the error rate threshold, performing the following steps: obtaining a Carrier to Interference plus Noise Ratio (CINR) return value; performing an adjusting procedure to obtain a CINR adjustment value; calculating an actual return value according to the CINR return value and the CINR adjustment value; and selecting one of a plurality of MCSs according to the actual return value.
