GreenPeak Launches the New GP501 ZigBee Radio Chip

March 27, 2013

A new generation of ZigBee transceivers with Wi-Fi coexistence schemes, deep packet inspection and wake-on-LAN features.

UTRECHT, The Netherlands -- GreenPeak Technologies, a leading semiconductor company in low power RF communication, with a rich offering of communication solutions for Smart Home applications, announces the GP501, a new generation of ZigBee transceivers which contains a sophisticated coexistence scheme that allows Wi-Fi, Bluetooth and ZigBee chips to work side by side in the same device. The GP501 also contains Deep Packet Inspection allowing deep sleep modes of set-top boxes and other host devices by means of Wake-on-LAN messages.

ZigBee shares the 2.4 GHz frequency band with other Wi-Fi equipment. The GP501 has a coexistence interface to allow optimized and co-located ZigBee/Wi-Fi radios to work in the same device, successfully avoiding RF interference when operating simultaneously. This coexistence interface enables arbitration over the shared radio frequency medium to prevent contention, signal degradation and data loss. Another advantage of the GP501 is its small size: its 32-pin 5x5 mm2 footprint allows integration into even the smallest product form-factors.

A new key feature of the GP501 ZigBee transceiver chip is the Deep Packet Inspection for ZigBee applications. Deep Packet Inspection (DPI) enables advanced packet management, allowing the host processor to go into a deep-sleep mode to conserve power. While most other ZigBee transceiver chips only include a superficial inspection of the MAC and PHY headers, the GP501 looks beyond these layers and executes a Deep Packet Inspection and based on the outcome, the chip can decide if the packet has to be passed on to the higher layer application or can be ignored. The DPI engine is also security aware, blocking unauthorized packets without involving the host processor and ensuring the system does not waste energy analyzing non-compliant packets. The DPI feature can be used for Wake-on-LAN functionality, where ultra-low power ZigBee is used to wake up the main processor from its sleep mode to enable Wi-Fi networking.

"The Wi-Fi Coexistence Interface and Deep Packet Inspection enabling Wake-on-LAN are new and exciting features of the GP501", says Cees Links, CEO of GreenPeak Technologies "These features make the GP501 the optimal choice for the set-top box/gateway market. With its small 32-pin footprint, the GP501 is a great successor to the already very successful GP500. Once again GreenPeak is leading the industry in adding smart functionality and superior performance to its ZigBee devices."

"Smart home networks will incorporate a variety of wireless technologies - all working in the same space," says Bill Ablondi, director of Strategy Analytics' Smart Home Strategies advisory service. "Having reliable and robust resistance to possible interference in the 2.4 GHz band enables set top box makers to create compact solutions that can support wireless Smart Home networks employing ZigBee for sensor and control networks and Wi-Fi for high volume content and entertainment networks. GreenPeak's new generation of compact ZigBee transceivers provides a comfort zone for developers."
