Introduction of Ubiquitous Networks Dr. Monir Hossen ECE, KUET ECE, KUET

Ubiquitous Network Definitions Ubiquitous came from Latin word which means exist everywhere. The word is popular in IT industry after Mark Weiser from Xerox Inc., Palo Alto, California propose the concept of ubiquitous computing in 1988. ICT Convergence that can be access by anybody, in anywhere, anytime and by anydevice. ECE, KUET 2

ICT Industry Trends in Developing Countries GSM/3G Operator Fixed Line Operator BWA Broadcast Media Current Players Voice Internet Television Video : Original Application : Widely Offered : Possible/Planned VoIP IP TV Mobile TV VOD Services Competition Area (Multimode Devices/Client) FMC: WiFi VoIP (thru PC/Laptop) VoIP with Client Software: Skype, Yahoo, talk VoIP (thru Handset) Digital TV (SIP) Setup Box Portal (Soft phone) BWA = Broadband Wireless Access SIP = Session Initiation Protocol FMC =Fixed Mobile Convergence ECE, KUET 9

Industry Trends Cellular Operators: VoIP Operators: Voice, Data Voice over IP Digital TV Mobile Phone with MP3. Camera Phone Integrated Phone & Broadcast TV. Multimode Handset Etc. Cellular Operators: VoIP Operators: Broadcast Operators: High speed Data over Cellular Video Call FWA (with Roaming) VoIP Services High Speed Data VoIP Services Future Services Dial Up Internet ADSL (ex: Speedy) FMC VoIP Services DEVICE CONVERGENCE (Multimode Devices) Internet VoIP Service Integrated WiFi and PDA Devices with Software Client Preinstalled. Embedded Skype on Handset Etc. BWA Arena (fixed/low mobility): Media Arena Fixed Line Operators: Internet Media over Internet PSTN FMC =Fixed Mobile Convergence FWA = Fixed Wireless Access ECE, KUET 10

What the UBIQUITOUS NETWORK can PROVIDE! A New Business Cycle and huge opportunities not only for ICT Industries but also for wider spectrum of industries. Nationwide Integrated ICT Services & applications lead to economic efficiency and to substitute new creativity-based industry. To Narrow the digital divide within the country. ECE, KUET 16

The Strategy needed Roll out a sound concept & plan to deploy Ubiquitous Network. To draw a holistic and condusive regulation Develop Ubiquitous Network Infrastructure Develop and establish the utility of Ubiquitous Network Infrastructure Promote an extensive usage of Ubiquitous Network services and applications.
