Among all the possibilities in the wireless universe, 802.11 Wi-Fi is chosen for its high-speed, low-latency channel, and for the widest possible compatibility in a topology including personal computers and mobile devices. However, the power requirement of a Wi-Fi transceiver can sometimes be difficult to afford for low-power devices. The complexity of protocols and mechanisms to regulate media access requires a consistent amount of controlling software, which is often distributed in binary form, and thus impossible to debug and maintain without the support of the manufacturers.

Wi-Fi provides large bandwidth and reasonably low latency, and may implement authentication and encryption at the data-link level.
