Worldwide wireless sensor networks shipments to reach 645 million in 2015, at a compound annual growth rate (CAGR) of 99.6%, compared to approximately 10 million chipsets in 2009, according to ABI Research.

The research firm said that 802.15.4 chipset shipments in 2009 were down by 30% compared to previous year.

However, it has been revealed that there is an increasing shift towards 802.15.4 based shipments compared to the proprietary offerings.

ABI research principal analyst Jonathan Collins said that because they are based on emerging technology, wireless sensor network adoption suffered during 2009 as pilots and early projects were scaled back or put on hold.

"However, 2010 has seen a significant rebound and strong shipment growth," Collins said.
