To meet consumers' expectations 2.4GHz peripherals must communicate with no loss of user data and fast (low latency) response in the presence of other aggressive 2.4GHz RF sources. Consumers demand uninterrupted communications and peripherals that fail to perform have no chance of selling in high volumes.

End users expect to use several 2.4GHz peripherals simultaneously (for example, keyboard, mouse, game pad and for the new generation of media centres, RF remote controls) often in very close proximity to Wi-Fi and Bluetooth-equipped products not least the PC itself.īut also others such as cell phones, headsets and cordless phones. Meeting these exacting constraints requires innovative design unencumbered by the restrictions imposed by today's IEEE-based standards.Ī good example is the wireless peripherals for PC. These latter schemes work well, but when it comes to ultra-low power wireless connectivity—where the unit's current can't exceed the peak current of coin cells or other small batteries typical of these applications and furthermore the batteries are expected to last for months or even years—these schemes demand power resources that just aren't available.

There are several established techniques for efficient use of the 83MHz width of the 2.4GHz band – ranging from the bullish approach of simply repeating the transmission on high power until it finally gets through to the elaborate direct sequence and frequency hopping spread spectrum schemes used by Wi-Fi, Bluetooth and ZigBee. It extends from 2.4 to 2.483GHz providing manufacturers plenty of opportunities to search for clear narrowband frequency channels within the allocation should their transceivers experience interference from other devices. This is not to say the 2.4GHz band can't cope. In addition, there are many proprietary manufacturers, including Nordic Semiconductor, that also employ 2.4GHz wireless technology. And it's only going to get worse (which raises the spectre that a product that works today could fail in the field tomorrow and become an expensive warranty issue).Ĭontemporary standards-based wireless technologies such as Wi-Fi, Bluetooth and ZigBee all crowd into the 2.4GHz band, along with various forms of wireless Ethernet and USB. On the downside, manufacturers have to deal with the band's heavy traffic.

On the plus side, manufacturers of RF products are fortunate that their 2.4GHz designs can be sold virtually worldwide without modification.

The global availability of the 2.4GHz band has its advantages and disadvantages. (Sections 5.138 and 5.150 of the Radio Regulations, when defining the ISM bands, don't quite use those exact words, preferring the drier statement “a device must expect interference,” but the sentiment is identical.) “You have been warned,” states the ITU-Radiocommunications Bureau (ITU-R) when it comes to dealing with interference in the license-free 2.4GHz Industrial, Scientific, Medical (ISM) band.
