LETI INNOVATION DAYS June 25th of 2019 IMPACT OF 5G DEPLOYEMENT ON DIGITAL INFRASTRUCTURE IN & AROUND BUILDING

considerations The promises can argue To provide the best in class data rate and latency according to the requested feature To be the first technology fitted the market needs from IoT devices to very high data rate hotspot through very small latency… Source: Qorvo Source: Qorvo Source: Ublox

CONSEQUENCES The matter is to consider what are consequences…. In and around buildings, for these three pillars ! Pillar mMTC: in building IoT devices in the concept of Smart Devices to do a Smart Building to make a Smart CitY Pillar eMBB: How to secure the Quality of Services within Building ? Pillars eMBB & uRLLC: How to provide the good architecture to delivers the promises in term of data rate, latency and reliability Translation in usage Source: Rodhe Scwartz Source: Infradata

mMTC: IoT the trends… The concept of smart Devices to do a smart Building to build a smart City SBA Emphasizes the Building and Cities Revolution Buildings become « service platforms  » Source: SBA

mMTC: IoT, NB-IoT or LTE-M Wireless solutions for in building IoT devices are available today in several technologies as Question is: Does NB-IoT can be a technical solution for Smart Home / Commercial Building? Specs NB-IoT LTE-M Fit for SH / SB ? Cost Few €  Peak data rate DL: 27,2kbps UL: 62,5kbps <100 kbps 1Mbps Full Duplex 375 kps(Half Duplex) Power consumption Best at very low data rate) Best medium Datarate Mobility Poor Yes Sensitivity -164 dBm (basement) -156 dBm Latency 1.5-10s 50-100ms NO Responsiveness Seconds up to min ms in Half Duplex s in Full Duplex Would not replace existing IoT technologies For Indoor communication But very Good for metering But would be a complementary technology to existing IoT technology

through « specific » program » mMTC: IoT the trends… Cloud to Cloud through « specific » program » Cloud 1 Cloud 2 Cloud 3 gateway gateway CUSTOMER NEED TODAY Customer requires interoperability at every level How to proceed ?

mMTC: IoT the trends… Cloud 1 Cloud 2 Cloud 2 Cloud 2 Customer also wants a reliable connection to his home. And Real estate Companies want to survey their building even if nobody’s is living inside… Cloud to cloud Cloud 1 Cloud 2 Cloud 2 Cloud 2 The way to survey the installation without the need of Internet connexion Agnostic & Universal gateway Agnostic & Universal gateway The common language to simplify interop between devices, the connection to the cloud and cloud to cloud API Local WPAN interop thanks to a common set of data element Local WPAN interop thanks to a common set of data element

NB-IoT/ LTE-M as a way to make connection With IN BUILDING IoT NETWORK Optical Link Border Router IoT Network Manager Optical Link

FREQUENCIES Considerations… The frequencies band of 5G and sometimes even 4G…. Source: Tech Mahindra … Are not compatible with new materials used in new buildings …. And mm Wave cannot even enter in a building Source: S2 Architetcure …. Because of mm wave, we should see many more closely spaced base station, dedicated to outdoor use with or without indoor to outdoor capability

…One service would be the indoor distribution for QoS… WHAT’s new for indoor digital architecture ? THE NEW STANDARD ISO/IEC 11801-6 Global agreement : last meters are Wireless. there is since 2 years a new standard for Building Digital Architecture. Standards stops to speak only about TO (Telecom Outlet) but now, also talk on SO (Service Outlet) Source: Bicsi …One service would be the indoor distribution for QoS… …Indoor digital infrastructure is still needed, even with the promises of …

Market Education needed to manage carefully the interferences WHAT kind of indoor distribution ? OPTION 1 The 5G network is locally generated in sub 6GHz through a dedicated active devices. Input from an optical link. Indoor Distribution done thanks to an actives network antennas distribution. Source ntt Market Education needed to manage carefully the interferences

WHAT kind of indoor distribution ? OPTION 2 The 5G network comes from the Base Station . RF Signal goes through outdoor / indoor active device. Still use an active Network antennas distribution Source ntt Source ntt Market Education needed to manage carefully the interferences
