The wireless HID (human interface device) market, which includes wireless mice, keyboards and remote controls, has historically been dominated by products operating in the 27 MHz band. But 2008 looks set to be a crossover year in which shipments of 2.4 GHz-based products outstrip those running at 27 MHz, thanks to wholesale product changes by major OEMs, reports ABI Research. The company expects that by 2011, 2.4 GHz products will account for triple the number of 27 MHz products shipped.
Some wireless HID products may employ other communication methods such as Bluetooth, but the company predicts that Bluetooth is too expensive to penetrate much outside of its current market territory. Declining cost disparities between 27 MHz and 2.4 GHz ICs as well as improved range of 2.4 GHz means that 2.4 GHz products are well positioned to take advantage of the need to support media center PCs.
A new ABI Research Brief, Wireless PAN Technologies in PC and Mobile HID, forecasts the total market for wireless HID to grow from just over 100 million units in 2005 to over 168 million units in 2012, at a CAGR of 8 percent. A respectable share of that growth may be claimed by companies such as Nordic Semiconductor and TI, which stand to profit from the shift to 2.4 GHz products.
