Node equipment, data packet forwarding method and mesh network system thereof

A node device configured in a mesh network, the node device comprising:

• a) a multimode transceiver configured to transmit and receive first type data packets and second type data packets;
• b) a controller configured to convert at least part of received first type data packets to said second type data packets that are then transmitted by said multimode transceiver, and being configured to convert at least part of received second type data packets to said first type data packets that are then transmitted by said multimode transceiver in a first mode, wherein said controller is configured to control said multimode transceiver to transmit and receive said second type data packets in a second mode;
• and
• c) wherein said first type data packets are configured as data packets of a predetermined physical layer protocol, and said second type data packets are configured as data packets with enhanced physical layer performance.

A method of forwarding a data packet from a node device in a mesh network, the method comprising:

• a) in a first mode, converting at least part of received first type data packets to second type data packets;
• b) transmitting said second type data packets;
• c) converting at least part of received second type data packets to said first type data packets;
• d) transmitting said first type data packets;
• and
• e) in a second mode, transmitting and receiving said second type data packets, wherein said first type data packets are configured as data packets of predetermined physical layer protocol, and said second type data packets are configured as data packets with enhanced physical layer performance.
