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

3. 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…

4. 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

7. 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?

Would not replace existing IoT technologies
For Indoor communication
But very Good for metering
But would be a complementary technology to existing IoT technology

…. And mm Wave cannot even enter in a building

…. Because of mm wave, we should see many more closely spaced base station, dedicated to outdoor use with or without indoor to outdoor capability

13. …One service would be the indoor distribution for QoS…
WHAT’s new for indoor digital architecture ? THE NEW STANDARD ISO/IEC
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)

…Indoor digital infrastructure is still needed, even with the promises of …

14. 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.

15. 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
