This article describes the IEEE 802.20 standard that was developed to meet the unique requirements for supporting high-speed data services while at the same time supporting full user mobility. It is a standard optimized to provide (IP-based) broadband wireless (Internet) access in a mobile environment, thereby affording network operators superior performance (e.g., higher data rates, lower latency) and lower costs as compared to networks built using standards that are not optimized for that purpose.

The paper introduces the broadband satellite multimedia (BSM) architecture standardised by ETSI. It defines a satellite independent service access point (SI-SAP) interface layer that separates the satellite independent features of the upper layers from the satellite dependant features of the lower layers, and provides a mechanism to carry IP-based protocols over these satellite dependent lower layers. This enables interoperability at the IP layer between satellite systems of different physical and link layers technologies that fully comply with the SI-SAP concept. A service-based network management architecture is also presented to allow management flexibility and integration of business and operation support functions, paving the way for satellite integration into the Internet of the future.
