Network communication and micro-electro-mechanical embedded technologies
have attracted much attention in recent years. Through these technologies, the capabilities
of sensing, identification, and communication can be embedded in various smart devices.
These smart devices can automatically connect to the Internet and form an intelligent network
called Internet of Things (IoT). However, these devices are embedded with different wireless
communication interfaces such as Wi-Fi and ZigBee. This paper presents the design and
implementation of an IoT access point that supports functionalities of coordination of various
wireless transmission protocols. Based on the existing Wi-Fi access point, we have
embedded a ZigBee module and implemented ZigBee and UPnP protocols into the designed
IoT access point, which supports ZigBee communication capabilities over the Internet.
