2 Labs ixem research activities wireless networks design and analysis wireless sensor networks design microwave sensors design electromagnetic propagation analysis antenna design microwave components design electromagnetic theory electromagnetic compatibility electromagnetic interference reduction solutions for digital inclusion ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 2
3 Long distance (low cost) wireless links => MKM Some authors are presenting this technology as an affordable and practicable solution for the construction of telecommunication infrastructures in remote and/or harsh locations Some other authors are strongly against it Are we allowed to think something in the middle? ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 3
4 1. ASSEMBLE a real-case experiment 2. DEFINE guidelines and constrains for network design 3. IDENTIFY the most suitable (but also reaistic) hardware and system architecture 4. CONSTRUCT transmitters prototypes 5. TEST solutions to enhance transmission capabilities 6. STUDY physical and mac layer limits 7. EVALUATE long term hardware living capacity 8. TEST hardware strength after exposure to hard environmental and meteorological conditions ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 4
5 Ip 1: the link is bi-directional Ip 2: the link makes use of unlicensed frequencies Ip 3: regulatory EIRP limitation Ip 4: hardware very cheap ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 5
6 1. Large bandwidth use microwaves 2. EIRP limitation choose radios with high sensitivity 3. Unlicensed freq enhance antenna directivity 4. Bidirectional link multiplex uplink and downlink on the same antenna 5. Bandwidth multiplex radios on the improvement same antenna ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 6

8 First objective: VERY LOW COST hardware Solution: Use of commercial OFDM-based wireless chipsets combined with a robust MAC layer How: using open source wireless physical drivers and low-cost PCs or SBCs to control the radio ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 8
9 Platform: Commercial PCs LINUX based Chipset: commercial Atheros chipsets originally born for x applications Drivers: either commercial or taken from the open source MadWiFi projects Frequency Band: Hiperlan (European 5 GHz unlicensed) Antennas: standard high gain antennas (up to 35 dbi) Communication protocol: either commercial or derived from distributions, with some modifications to support p2p communications Frequency use: hybrid TDD/FDD scheme RF components: properly designed Output: an experimental network to test the identified solution ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 9

21 1. lightning: one transmitter destruction at Capanna Margherita (in the same occasion also the satellite connection was affected in the same way); 2. ice falls: solar panels damaged at Capanna Margherita (in the same occasion also the satellite power supply was affected in the same way); 3. overvoltage damages: two times (MB and ATX power supply wrecked, no problems for radios), due to failures of the solar panels regulator; 4. link down-time: around 0% for links under 100 km, up to 4% increasing the distance to 300 km; the link towards Capanna Margherita, in presence of strong snowstorms, was experimenting extraordinary attenuation; ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 21
22 5. hardware wear: no appreciable problems for radio cards, new ATX motherboards, automotive ATX power supply; only one SBC failure over twenty boards, after 9 months of usage; one failure over ten recycled motherboards, after 6 months of usage; two failures over ten recycled standard ATX power supply; 6. strong winds: no problems, even if some hops (Capanna Margherita) were exposed to winds up to 200 km/h; 7. extreme temperatures: destruction of two batteries below -30 Celsius (after we started isolating them) ITU-T Kaleidoscope 2009 Innovations for Digital Inclusion ixem Labs p. 22
23 1. MKM networks can be reliable as a first step in the implementation of communication infrastructures in developing regions. 2. MKM networks can be easily installed, they do not need high expertise, can be efficient for basic service provisioning, they can be simply scaled up. 3. We must keep in mind that transmission capacity and long term duration are not comparable with more developed, transmission systems. 4. Thanks to their low costs, MKM networks can be implemented for the construction of simple backhaul networks, for essential services like telemedicine and distance learning applications, or to start the digital inclusion process.
