1. A system for fast handover in an optical multi-cell communication system, comprising:
a plurality of access points being arranged for advertising their presence by transmitting shortened frames without a payload portion in an allocated pre-defined part of a common channel of a frame cycle of a link layer or physical layer protocol, wherein each of the shortened frames contains an identifier of the respective advertising access point; and
at least one end point being arranged for searching for neighboring ones of the plurality access points to anticipate an upcoming handover by detecting an advertised shortened frame in the common channel, and for transmitting a pre-registration request for preliminary registration to a detected neighboring access point prior to deciding on a handover.
