Mobile Internet3G vs. 4G or both...

Background

• There is a lot of discussion what 4G actually
  means...
• Will it be logical successor of 3G in timely
  fashion?
• We see at HMV that no, evolution of 3G 4G are
  parallel but starting from different paradigm,
  but possibly uniting in the Next Generation thus
  actually 5G
• 3G is evolving from Mobile Phone to Mobile
  Communicator to Mobile PDA (UMTS, WCDMA, i-Mode,
  WAP)
• 4G is evolving from PDA to Mobile Communicator to
  Mobile Phone (WLAN, GPRS, VoIP-client)
• Actually, we see that there is room for both in
  the market

Background

• At the same time there are two massive
  convergencies going on
• All IP
• Military-Commercial
• The Main Integrator will be Software Radio
• SoThank God for SWRADIO DSIG within OMG and
  Wireless CORBA (Telecom DTF) !

Towards the personal Internet in EU

• Internet access increasingly based on mobile and
  interactive digital TV platforms
• By 2003, 65 of the EU population will have a
  mobile phone
• and 85 of mobile phones will be
  Internet-enabled

Software radio

• Re-programmable radio of the future which can be
  configured (even in real time) to function in
  many radio systems and if necessary even
  simultaneously
• Dominant design principle in future
• All functions are to maximum extent software
  defined
• Includes also a smart multiband antenna system in
  the future

7
Main advantages of software radio

• The size, power consumption and complexity of
  radio will decrease---gt also cost of production
  is smaller
• Shorter development time
• Bridge or gateway function between different
  systems-gt makes interoperation possible
• Radio interface or communication protocol can be
  changed on the fly
• Adaptive radio interface possible
• Future proof
• compatibility with legacy and future waveforms

Military multiband multimode -basestation

• Basestations support both commercial and
  military waveforms
• Advantages
• No need for changes in terminals
• Drawbacks
• Basestation complicated and expensive
• different waveforms
• signalling
• etc
• does not support the principle of
  decentralisation

Commercial multiband multimode -basestation

• Advanced Communications Technologies released
  01/2001 SDR-basestation(SpectruCell), which
  includes GSM, CDMA, 3G,UMTS waveforms
• coming on the market this year
• 400 MHz2,9 GHz
• No application specific circuits
• for example CDMA function without specific
  circuit(like Qualcomm)
• 1024-QAM radiolinks can be used also to combine
  different basestations

Military multiband multimode terminal

• Terminals will support both commercial and
  military waveforms
• Advantages
• Parallel use of existing networks ---gt supports
  the principle of decentralisation
• Terminal uses at same time only one waveform---gt
  implementation architecture simple
• Drawbacks
• Terminal more complicated compared to
  singlemode radio
• Commercial application 4G(3G)

11
Development of commercial mobile communication
networks

• 1G analog cellular networks
• NMT, AMPS, TACS etc
• Digital 2G networks
• GSM, through evolution path data rate increases
• HSCSD
• GPRS
• EDGE---gt over 384 kbit/s
• WAP
• wide range
• IS 95, IS-136 CDMA, IS-136 TDMA

12
Development of commercial mobile communication
networks

• 3G UMTS (WCDMA-techniques)
• Two versions UMTS_1999 and UMTS_ 2000
• core networks either enhanced GPRS or
• IP-network
• Handover GSM lt--gt UMTS---gt multimode radios
• Hotspot coverage
• max theoretical data rate 2 Mbit/s
• Offers for mobile user multimedia services and
  convergence between fixed, cellular and satellite
  networks

13
Development of commercial mobile communication
networks

• 4G
• Not a new waveform, butAs wide Integration as
  possible of all existing systems based on
  software radio and IP-technology
• all systems, all services, at low price
• private and public networks

Development of Tactical Radios (ground forces)

• 1. Generation
• Analog radios
• analog FM-modulation
• very slow data rate using typically
  FSK-modulation
• 2. Generation
• Digital radios
• deltamodulated voice and for example FSK-type
  modulation
• slow data rate (typically under 9.6 kbit/s)
• frequency hopping as ECCM-method
• Support of packet data
• for example Tactical Internet standard
  MIL-STD-188-220
• Ad Hoc type of network setup

• 3. Generation
• Multiband multimode radios
• same radio includes for instance HF, VHF and
  UHF waveforms
• Support of many waveforms (520)
• Enhanced packet data transfer
• Possibly includes also commercial or public
  safety waveforms(GSM, TETRA etc.)
• 4. Generation

16
Convergence of Commercial and Military Radio
Networks

• Strong encryption-, integrity- and authentication
  methods are used to guarantee secure data
  transfer
• Ad Hoc mode in the software radio enables
  automatic network management
• For longer range commu-nication the commercial
  or military networks are used as soon as they are
  available
• European cooperation would be necessary in order
  to develop 4G tactical software radio

• Both Commercial and Military Network will be
  IP-based
• Commercial and also tactical routers support
  Mobile IP and IPsec
• Untrusted Internet can be used to connect
  tactical intranets VPN(Virtual Private
  Network)
• In principle future military multimode
  software radio can be used seamlessly both in
  military and commercial radio networks
• core network is responsible of mobility (Mobile
  IP,Wireless CORBA)

17
Summary

• The convergence of commercial mobile systems (3G
  and especially 4G) is based on re-configurable
  radios (software radio)
• Future tactical radios will also be software
  radios
• the need for multiband multimode radios is
  obvious in future
• parallel use of commercial and military radio
  networks
• adaptive waveforms
• gateway-function possible
• interoperability between legacy and future
  waveforms
• Closer cooperation between commercial-military is
  needed
• OMG offers an excellent forum for this
