Readying CERN for connected device era Speaker: Rodrigo Sierra Hubert Odziemczyk CHEP 2019 1
Devices “Everything that can be connected will be connected” CHEP 2019 2
Io. T networking • • • Range Data rate Traffic pattern Power Mobility Number of devices Price Security Coverage Spectrum CHEP 2019 3
Bandwidth Power consumption Io. T networking… WLAN Cellular 802. 11 xx 2 G, 3 G, 4 G PAN NFC, Zig. Bee, BLE LPWAN Lo. Ra, Sigfox, NBIo. T Range CHEP 2019 4
LPWAN Long range Easy and cheap deployment Low data rate LPWAN Long battery life Low device cost Massive number of devices CHEP 2019 5
Lo. Ra. WAN • • Lo. Ra Alliance (Semtech, Orange, IBM, Cisco… up to 500) Mature: several national-wide and private networks deployed Unlicensed spectrum: independent of national operators (and borders) High sensitivity (-137 d. Bm): indoor coverage Datarate between 0. 3 and 50 kbps Symmetric encryption and authentication using AES Downlink capabilities (although primarily uplink) Lo. Ra Physical layer • Enables long-range link • Proprietary modulation technology from Semtech Lo. Ra. WAN Medium Access Control • Open standard developed by the Lo. Ra Alliance CHEP 2019 6
Lo. Ra. WAN architecture Radio Engineering End-devices Io. T service development User application Gateways • • Packet forwarding CRC control Application Server #1 T Network Server Application Server #2 Application Server #3 • • T Lo. Ra Provisioning Security (encryption, identity, key mgmt) Duplicate control Application differentiation Lo. Ra. WAN CHEP 2019 7
CERN Lo. Ra. WAN architecture CHEP 2019 8
CERN Lo. Ra. WAN architecture • Central IT services: • • • Service orchestration Monitoring & operation Device provisioning Network configuration Central IT data services for the end user: • • • Kafka connection AAA managed by the data services User decides processing, storage and access CHEP 2019 9
Tunnels • • • Coverage Radiation tolerance Specific services CHEP 2019 10
What’s coming? • • New requirements and use cases New technologies and standards Wireless is cool Challenges will remain: • • • Interoperability Security Privacy Scalability Coverage Qo. S Io. T as a Service … Control BYOD 2. 0 CHEP 2019 11
