European Mobile and Personal Satellite Workshop (EMPS 2000)
Summary:
The European Mobile and Personal Satellite communications workshop
was established in 1994 in response to growing research interest
internationally in the integration of terrestrial and satellite
personal communications systems. The Workshop has provided a
valuable European focus for the exchange of novel ideas and research
outcomes in a continuously expanding area of technical advance.
The previous three workshops have been held in venues in Italy,
the fourth event in the series, to be held in London in conjunction
with PIMRC 2000, marks the emergence of EMPS as a significant
component of the international conference calendar.
The programme for EMPS 2000 follows a trend established in the
1998 event of emphasising the growing importance of network aspects
in developing seamless delivery of telecommunications services
in integrated satellite-terrestrial systems. Sessions deal with
review of the current status of satellite personal communications
systems, aspects of air-interface optimisation, networking, progress
of satellite-UMTS and the projected evolution of broadband services.

Technologies for Wireless Packet Telephony
Summary:
Packet telephony is attracting significant interest in both the
telecommunications and Internet communities. The emergence of
packet telephony will create new services and allow greater flexibility
and efficiency in the way people communicate. At the same time,
demand for cellular telephony is exploding, with the number of
subscribers predicted to exceed 500 Million in the year 2000.
The marriage of these two technologies promises the benefits
of packet telephony combined with the freedom of user mobility.
It does, however, raise a set of difficult technological challenges.
The aim of this tutorial is to explain the key concepts and technologies
involved in designing a wireless packet telephony system. Topics
covered will include quality of service in wireless networks,
Mobile-IP, protocols for real-time transport (RTP), and call
signalling (H.323, SIP). The tutorial will include discussions
of emerging wireless systems and recent research developments.

Ad-Hoc Radio Connectivity via the BluetoothTM System
Summary:
In the last decades, progress in radio and VLSI technology has
fostered the widespread use of computing and communication devices
for commercial usage. The success of consumer products like PCs,
laptops, PDAs, cell phones, cordless phones, and their peripherals
has been based on continuous cost and size reduction. Recently,
a new universal radio interface has been developed enabling these
electronic devices to communicate wirelessly via short-range
ad-hoc radio connections. The BluetoothTM technology eliminates
the need for wires, cables and the corresponding connectors between
cordless or mobile phones, modems, headsets, PDAs, computers,
printers, projectors, and so on, and paves the way for new and
completely different devices and applications. The technology
enables the design of low-power, small-sized, and low-cost radios
that can be embedded in existing (portable) devices. Eventually,
these embedded radios will lead towards ubiquitous connectivity
and truly connect everything to everything. Radio technology
will allow this connectivity to occur without any explicit user
interaction. This tutorial present an in-dept technical overview
of the BluetoothTM system. Items that
will be discussed are:
- general design issues of ad-hoc radio systems
- Physical layer
- MAC and DLC layer
- BluetoothTM network topology
- BluetoothTM hardware design
- Example of BluetoothTM applications

Wireless Internet: Networking & Protocol Aspects
Summary:
The core network architecture and air interface of the third
generation (3G) wireless systems enable packet-switching, in
contrast to the current 2G systems which are circuit-based. Key
challenges in the packet-based wireless network includes protocol/mechanism
to offer higher voice capacity with quality that is comparable
to that of the 2G system and to provide wireless subscribers
with full scope of the Internet services such as Web Browsing,
Internet video/audio entertainment, etc.. Furthermore, the interworking
of the high speed wireless access and the Internet backbone need
to be designed and developed to efficiently support a range of
integrated end-to-end wireless Internet services.
In the past, much attention has given to the designs of high-speed
air interface for wireless Internet services. Lately, protocol
designs and networking aspect of the 3G wireless networks to
support a range of services including real time, streamline video/audio,
Web browsing, etc. have been discussed in various standard committees.
In ETSI SMG2, efforts on modifying/enhancing General Packet Radio
Service (GPRS) to support real-time applications have been started.
In 3GPP, various inter-working scenarios of Mobile IP and 3G
wireless network are included in release 99. In IETF, cellular-IP,
IP mobility using HAWAII have been proposed. With all these different
approaches, the most efficient/feasible design for IP host mobility
remains to be developed.

Broadband Radio Access Systems & LANs for Multimedia Applications
Summary:
Massive growth in wireless and mobile communications, the emergence
of multimedia applications as well as high-speed Internet access
are the key drivers towards a new demand for radio-based broadband
access and local area networks. Third generation mobile cellular
systems aim at networks providing instantaneous user bit rates
up to 2 Mbit/s per radio channel while it is expected, that many
future real-time and multimedia services require such networks
that can provide users in geographically limited areas with data
rates exceeding 2 Mbit/s. As a response to this need, different
standards have been or currently are being developed for such
broadband systems at 2.4 GHz and 5 GHz, as in Europe (HiperLANs
type 1 and 2), in the U.S. (802.11) and in Japan (MMAC Systems).
This tutorial deals with these systems, their similarities and
differences, in particular with respect to:
- access network topology
- physical layer (e.g. modulation techniques: single carrier versus OFDM)
- medium access control (MAC)
- data link control and error recovery
- radio network management functions (e.g. handover, link adaptation, dynamic frequency selection and power control).
In addition, the capability of these systems to interwork with different core networks (e.g. IP, ATM, third generation cellular) will be addressed.

The 3GPP System for IMT-2000
Summary:
The international body 3GPP (Third Generation Partnership Project)
is specifying the third generation radio access system, which
is based on the UTRA (UMTS Terrestrial Radio Access Network)
concept. ITU-R approved this concept as one of the IMT-2000 family
members in December 1999. The UTRA concept corresponds in major
parts to the proposals from ARIB (Japan), to one of the Korean
proposals (TTA) and to one of the US proposals from T1.
The UTRA concept was originally designed in detail in the European
standardization body ETSI SMG2 based on European research activities
in the ACTS FRAMES Project and contributions from Japan and the
US. The further development and harmonization of the close proposals
from Europe, Japan, Korea and the US took place in 3GPP with
members from all three regions America, Asia and Europe. Parallel
activities are ongoing in 3GPP2 for the cdma2000 based concept.
Both groups are cooperating based on the agreement of the Operators
Harmonization Group to achieve a harmonized concept for a globally
available concept.
This Tutorial will present the radio interface of the 3GPP concept
which comprises an FDD and a TDD component, and the radio access
network UTRAN. The FDD component is based on WCDMA and the TDD
component is based on TD-CDMA.
Outline:
- Introduction and market conditions
- Technical requirements on third generation mobile radio systems
- International frequency allocation and spectrum vision
- International standardization activities
- 3GPP system
- FDD component
- DD component
- System simulations
- Harmonization activities
