Device and method for clock synchronisation in a wireless network

A device for wireless communication according to a standard communication protocol,

• said device being adapted to operate at the Physical layer and/or Medium Access Control layer of said protocol, and comprising a Wireless Network Interface Controller, abbreviated WNIC, said WNIC comprising:
• a transmitter adapted to transmit wireless signals according to said standard communication protocol;
• a receiver adapted to receive wireless signals according to said standard communication protocol;
• a WNIC clock, implementing a local timer according to said standard communication protocol, said WNIC clock being adapted to generate a clock time based on a reference time and a clock frequency and comprising a counter, and
• said device further comprising:
• an interface adapted to receive offset correction information and skew correction information from one or more protocol layers higher than said Medium Access Control layer, said skew correction information comprising a skew correction value;
• an offset correction unit adapted to correct said reference time of said WNIC clock based on said offset correction information;
• a skew correction unit adapted to correct said frequency of said WNIC clock based on said skew correction information, by periodically adjusting said counter of said WNIC clock based on said skew correction value.
