Abstract
Bluetooth is the communication protocol
standards that define a physical layer and
a MAC layer for wireless
communications within a short range
(from a few meters up to 100 m) with
low power consumption (from less than
1 mW up to 100 mW). Bluetooth is
oriented to connecting close devices,
serving as a substitute for cables, while
Wi-Fi is oriented toward computer-tocomputer
connections, as an extension of
or substitution for cabled LANs. In this
article we offer an overview of these
popular wireless communication
standards, comparing their main features
and behaviors in terms of various
metrics, including capacity, network
topology, security, quality of service
support, and power consumption.
