27. June, 2004D2 Project Presentation5 Main objective To explore how a high performance broadband mobile network based upon inexpensive wireless LAN technology and unused capacity in the fixed access networks can be established By-passing user
27. June, 2004D2 Project Presentation6 Rational behind Most users will in few years have broadband access over the fixed network The capacity of these access line is poorly exploited Wireless LAN technology is getting popular as the dominant home networking technology. Wireless LANs have large capacity and are often poorly exploited OBAN intends to investigate how the public can obtain access to these resources and what kind of services can be provided over this network.
27. June, 2004D2 Project Presentation7 Rational behind (cont’d) Coverage per base station in mobile networks: GSM (14 kb/s) - 50 km 2 (r < 4 km) UMTS1 (384 kb/s) - 3 km 2 (r < 1 km) UMTS2 (2 Mb/s) - 1 km 2 (r < 600 m) 4G (< 20 Mb/s) - 0,03 km 2 (r < 100 m) GSM UMTS 14G No of base stations >100 000 (Norway) 2 The high number of base stations in broadband mobile networks requires a new broadband infrastructure to feed all base stations. The required invest- ments will therefore be extremely high. The OBAN project introduces an alternative way to achieve the same, but at much lower cost.
27. June, 2004D2 Project Presentation8 Areas of foci to reach the main objective Security: because we are opening up today’s privately disposed access lines and wireless LANs for public use Mobility: because we need to know what degree of mobility can be provided in areas of randomly located WLAN access points connected over the fixed networks access lines QoS: because we want to know how to provide QoS to users in a heterogeneous network composed by technologies with limited QoS abilities
27. June, 2004D2 Project Presentation9 Areas of foci to reach the main objective 3G/B3Gto explore and evaluate how the OBAN concept can be integrated with the 3G/B3G visions. Coverage: to estimate potential coverage and capacity of an OBAN network. Smart antennas are investigated in order to improve network performance Commercial: to investigate how the OBAN concept may be utilised commercially and how legal and regulatory issues may affect deployment in large scale
27. June, 2004D2 Project Presentation10 Areas of foci to reach the main objective The RGis the key component in the system and need extensive investigation through implementation to verify the concept
