Computer Communication Systems Laboratory (CCslab) at Dept. of Teleinformatics, KTH

Development and Activity Plan for 1995/96

• protocols: implementation, testing, performance measurements, ...
• interaction with those designing and building link and physical layer devices
• interaction with those designing and building application layer clients and services
• effects of mobility on computer communication - when to hide mobility and when to expose it
• ...

Research

• The "VLSI" price curve - due to increasing using of VLSI fabrication techniques as well as moving to digital electronics
• Consumer communications equipment: CB radios, cordless telephone, cellular telephones, ...
• User expectations due to the above items, and
• Economic and political changes with respect to wireless communication.

Traditionally users have had to treat specturm as an extremely valuable resource and mobile communications devices were expensive devices which were only used by very special customers. This has all changed:

• Microcells and picocells combined with high speed backbone technology has changed the economics - so that specturm is often not the limiting factor;
• Volume manufacturing of consumer communication devices has changed the pricing and avaialbility of mobile communication devices; and
• The base of users has broadened to closer to the "average person", (with more than 20% of the population of Sweden having cellular phones).

While the base technology is rapidly developing most wide area service is still only 10s of kilobits per second and local area service is only 100s to 1000s of kilobits per second. In conjuction with researchers in Radio Systems, Electronic System Construction, etc. we are attempting to find the architecture and protocols necessary to support future mobile computing and communication systems.

Teaching

• Telesystem gk (2G1307) [previously 2G1961 and 2G1962]
• Mobile Computing and Communication module for the Telecommunications finger course (2G1303)

• no planning for strictly graduate courses is complete at this time, there is some discussion of a course on location dependent computing and communication (based on G. Liu's recent Ph.D. thesis in this lab).
