The 18th Tyrrhenian Workshop on digital communications is devoted
to wi- less communications. In the last decade, wireless
communications research boosted launching new standards and
proposing new techniques for the - cess technology. We moved from
the UTRA standard capable to transmit 0. 5bit/s/Hz to WLAN which is
promising 2. 7bit/s/Hz. Now wireless c- munication systems are
facing a ?ourishing of new proposal moving from multiple antennas
at transmitter and receiver side (MIMO systems), to new
powerfulForwardErrorCorrectionCodes,toadaptiveradioresourcemana-
mentalgorithms. Thenewchallenge,however,isthemovetowardsmultimedia
communications and IP technology. This move implies e?orts in
several new aspects. First of all an open network, as IP is,
imposes the necessity of a - cure network, to guarantee the privacy
of the ongoing communications, avoid the use of the networks by
unauthorized customers, avoid the misuses and the charge to third
parties of the cost of the connection. Also, quality of service
(QoS) of the communications is becoming a must in IP networks which
are carrying services which need a guaranteed QoS as telephony,
real time s- vices, etc. To get this new target some form of access
control to the network must be setup. Recently, new form of
communication networks has appeared to collect data for several
applications (sensor networks, ad hoc networks, etc. ) and they
need a connection with a backbone network which could be a wireless
one with a larger range than the sensor or ad hoc networks.
