1. A gateway for use in wireless communication, wherein the gateway comprising:
a server communication unit; a node communication unit; and a control unit; wherein:
the server communication unit for communicating with the server;
the node communication unit for communicating with at least one node via a protocol having a LoRaWAN-based communication protocol, the node communication unit receives a data packet provided and encoded by the node, wherein the data packet includes data collected by the node,
wherein the data packet has a LoRaWAN-based structure including a modified physical payload section and four information fields according to the LoRaWAN communicating protocol which are a preamble, a physical header, a physical header CRC, and a CRC inserted into the data packet automatically,
wherein the physical payload section includes a medium access control layer header subsection and a medium access control layer payload subsection, characterized in that:
the medium access control layer header subsection includes a message type information for indicating a type of a data packet,
the medium access control layer payload subsection includes a frame header subfield, wherein the frame header subfield contains a device address information which includes a node address of the node that generates data packets and a gateway address of the gateway to which said node communicates, and a frame control information which includes an acknowledgement information and a portion for reserved for future usage for customizing a frame controlling;
the control unit is configured for controlling the gateway to:
only communicate with the server(s) and the nodes without communicate with other different gateways within a same network,
receive a data packet sent from node if said data packet includes a gateway address information which is specified in the device address information above identical with a gateway address information of the gateway,
generate and send an acknowledgement information to said node after the gateway has received said data packet,
decode said data packet sent from said node for obtaining data collected by the node, and process said data at the gateway for obtaining a processed data, and
send the processed data to the server via the server communication unit.
