Mobile multimedia services
using DAB and GSM
Mobile multimedia services with high data rates will bring significant
operational flexibility to professional sectors such as publishing and the construction
industry. The ability to handle large data volumes for graphics and multimedia
information, such as construction plans, will be a key benefit.
The MEMO project is developing a generic architecture for mobile interactive multimedia
services. The results are based on experience with two generations of prototypes, user
requirements studies and evaluation of user trials. MEMO is developing a generalised
service model with hardware and software infrastructure, to implement a variety of
interactive data-casting services where mobility is needed.
The target architecture is a two-way connection combining a broadband down-link and a
low bit-rate up-link. Trials are being carried out using experimental networks in France,
Germany and Sweden. The data terminals used are laptop personal computers (PCs) and
personal digital assistants, which are being integrated with receivers and mobile
telephones. The project expects to be able to adapt these terminals to other application
areas as necessary.
Two target services are planned. One is for electronic publishing (newspaper,
videotext) with strong interactive capabilities. The other is in the construction
industry, to support large on-demand data downloads for user groups and collaborative
Some of the terminals and the applications are operating on the stand. Visitors can
also view a typical infrastructure and examine the MEMO specification.
