Wireless sensor nets seek “killer” application
Wireless sensor networks are not being fully utilized in commercial markets due to the lack of a ‘killer application’ to drive interest, a Plextek led report for U.K. communications industry regulator Ofcom has concluded. The 10-month study was commissioned to examine technology developments in wireless sensor networks, along with likely market growth scenarios and what the spectrum implications would be.
The report suggests WSNs may begin to become more widely deployed over the next three to five years, with systems continuing to adopt existing licence-free bands including 13.56MHz, 433MHz, 868MHz and 2.4GHz. The main issue for WSNs will be the crowding of bands, especially 2.4GHz with the increasing use of Wi-Fi.
