    The design issues for the next-generation wireless infrared systems are discussed. An advanced infrared system is proposed to provide reliable high-speed short-range wireless communication throughout indoor environments. In the physical layer, the range of communication is extended for L-PPM infrared links by using repetition rate coding, which greatly increases the symbol capture probability at t...

    A new ATM AAL2 to support low-bit-rate and delay-sensitive applications in an ATM environment has been approved by the ITU-T and ATM Forum. AAL2 allows multiplexing of voice/data packets (minicells) from different users in a single ATM connection, thus improving the utilization of the network resources. This article identifies issues related to AAL2 such as the application environment, the gain ob... View full abstract»

    In a cellular digital packet data network, the RF channels that support the communication between mobile terminals and the fixed network are continuously changing in terms of availability and communications quality. The management layer that deals with this dynamically changing RF environment and aims at continuously providing the best possible RF channel between a mobile terminal and the fixed ne...

    Following the FCC's auctions for local multipoint distribution service spectrum, the US spectrum holders are expected to go on a rapid move, first toward evaluating the technology in trials, and further toward gradual deployment and commercial availability. The LMDS spectrum will offer new ways to break the local loop bottleneck by delivering a full suite of high-speed service interfaces to busine... View full abstract»

    The method of billing users for mobile telephony is based on systems developed over time for fixed networks. We survey the technology involved, and argue that these systems will become increasingly inadequate for large populations of mobile users where frequent roaming is involved. We present two micropayment schemes which permit a caller to inject a payment stream into the network which allows mu... View full abstract»
