The ZB2430 uses the ZigBee protocol stack, a network layer protocol which uses small, low power digital transceivers based on the IEEE 802.15.4 hardware standard. The 802.15.4 standard is a specification for a cost-effective, low data rate (<250 kbps), 2.4 GHz or 868/928 MHz wireless technology designed for personal-area and device-to-device wireless networking.

The IEEE 802.15.4 standard specifies the hardware requirements, including frequency bands, receiver sensitivity, modulation and spreading requirements. The ZigBee layer is the software layer that sits atop the 802.15.4 PHY/MAC layer and performs all packet routing and mesh networking.

There are three device types present in a ZigBee network: Coordinator (Full Function Device), Router (Full Function Device), and End Device (Reduced Function Device). Each network consists of a single Coordinator, optional Router(s), and optional Reduced Function End Device(s).

Coordinator

The Coordinator is responsible for establishing the operating channel and PAN ID for the entire Network. Once the Coordinator has established a Network, it allows Routers and End Devices to join the Network; assigning each device a unique 16-bit Network Address.

The Coordinator is intended to be mains powered (always on).

Router

•One Coordinator per Network

•Establishes Channel and PAN ID

•Responsible for Network formation and maintenance

•Full Function Device

•Packet routing capabilities

•Mains powered (always on)

•Power down modes are not supported

•Network address of 0x0000

Routers are responsible for creating and maintaining Network information and determining the optimal route for a data packet. Routers must first associate with the Network before other devices can join through them.

Routers are intended to be mains powered (always on).

•Multiple Routers can be used

•Allows other Routers/End Devices to join the Network

•Full Function Device

•Packet routing capabilities

•Mains powered (always on)

•Power down modes are not supported

•Unique netowork address dynamically assigned by parent
