Gateway apparatus for providing multi-channel functionality in sensor network, and method and apparatus for interfacing using serial peripheral interface in the gateway apparatus
First Claim
1. A gateway apparatus comprising:
- a signal processing unit transmitting and receiving data to and from a core network and including a serial peripheral interface (SPI);
a plurality of wireless transmit/receive units transmitting and receiving data to and from a sensor network via their respective communication channels which differ from one another; and
an SPI interfacing unit which is connected to the wireless transmit/receive units, which selects a wireless transmit/receive unit to which a data frame received from the signal processing unit via the SPI is to be output from among the wireless transmit/receive units, based on information regarding selection of the wireless transmit/receive unit, wherein the information is contained in the receive data frame, and which outputs data frames received from the wireless transmit/receive units to the signal processing unit via an SPI.

Abstract
Provided are a gateway apparatus for providing multi-channel functionality in a sensor network, and a method and an apparatus for interfacing using serial peripheral interface (SPI) in the gateway apparatus. The SPI interfacing apparatus is connected to a plurality of wireless transmit/receive units, and receives a data frame via an SPI to output the data frame to a wireless transmit/receive unit, based on information regarding selection of the wireless transmit/receive unit, wherein the information is contained in the data frame. Then, the SPI interfacing unit receives data frames from the wireless transmit/receive units to output the data frames in a predetermined order via an SPI. Thus, the wireless transmit/receive units for providing multi-channel functionality can interface a signal processing unit by using an SPI method.
