+ * @par Changing the PHYsical transport of a connection
+ *
+ * Once a connection has been established, it is possible to change the physical
+ * transport used between the local and the distant device. Changing the transport
+ * can either increase the bandwidth or increase the communication range.
+ * An increased bandwidth equals a better power consumption but also a loss in
+ * sensibility and therefore a degraded range.
+ * Symmetrically an increased range means a lowered bandwith and a degraded power
+ * consumption.
+ *
+ * Applications can change the PHY used by calling the function setPhy. Once the
+ * update has been made the result is forwarded to the application by calling the
+ * function onPhyUpdateComplete of the event handler registered.
