How Bluetooth® technology makes wireless communication reliable
The challenge of wireless interference and the key techniques Bluetooth technology uses to overcome it.
The challenge of interference
One of the biggest challenges for any wireless technology in providing reliable data communication is interference.
Unlike wired data communications technologies, wireless technologies must share the transmission medium. For example, Bluetooth technology operates in the same 2.4 GHz ISM frequency band as Wi-Fi and technologies that utilize the IEEE 802.15.4 standard. As a result, it’s possible for a packet being transmitted between two Bluetooth devices to be corrupted or lost if it collides with a packet being transmitted at the exact same time and frequency channel as other in-range Bluetooth, Wi-Fi, or 802.15.4 devices.
How Bluetooth® technology overcomes interference
Bluetooth technology has adopted several techniques to lower the probability of collisions and offset inevitable packet loss.
