1. Low Cost Infrastructure project SNCNW2003; 2003-09-08 Jan Markendahl

2. Starting point of research Wireless systems 2015 -Data rates,capacity ~100 time larger than today -Cost ~ todays GSM voice services Current Cellular solutions -Cost ~ bandwidth, capacity Cost structure of cellular solutions today -Telecommunication equipment is not the dominant part of operator costs -Costs of Sites, Operation& Maintenance, Interconnection are the major costs for the network

3. Low Cost Infrastructure project Attack the problem from two sides Set of solutions Problem Reduce other costs than telecom equipment, e.g sites, planning Find good wireless solutions and ”trade off´s” between bandwidth, QoS, coverage and costs

4. Low Cost Infrastructure project

5. Use the current base station approach but make more cost efficient designs Use complex access points and reduce the number Use a large number of low complexity access points Move functionality from access points to the terminal Low Cost Infrastructure project Possible research directions

6. Low Cost Infrastructure project Research areas Use complex access points and reduce the number Use a large number of low complexity access points Move functionality from access points to the terminal AP´s with antenna arrays ”BIG cellular” Multiple Antenna terminals & MIMO processing Shared wireless networks Systems with MultipHop terminals AP´s for Local Access Providers AdHoc Heterogenious Networks

7. Low Cost Infrastructure project - WP´s AP´s with antenna arrays ”BIG cellular” Multiple Antenna terminals & MIMO processing Shared wireless networks Systems with MultipHop terminals AdHoc Heterogenious Networks WP3. Spatio temporal Designs WP2. Distributed AdHoc Infrastructure WP1. Infrastructure deployment strategies and business models AP´s for Local Access Providers Business models Cost structures
