for the internet of things
@janjongboom
CTO OfficeInternet of Things
IoT is spread outFour different teams
Four teamsAll ended up same position
Before we can do IoTwe need to solve connectivity
CellularLong range, but week of battery
2.4 GHzBluetooth, Zigbee, etc.
Years of battery, max. 100 meter
Connecting sensors is a new problemFirst time: bandwidth doesn't matter
Time for new tech!
Long Range, Wide AreaSub GHz spectrum No gateway pinning Big antenna picks out signals
ResultsPenetrates buildings, walls
2 KM range downtown 15 KM range open-field
Only draws power when emitting
What makes it perfect for sensors...
Variety of vendorsLoRa, Sigfox, Siglo, Weightless-N
LoRa
Why LoRa?Available today Relative low cost
Gateways € 1200 Radio chip € 6 Full sensor € 30
First projectTelenor Eiendom
400 sensorsMaking Fornebu smart
Building 100 ourselvesCreate hardware competency in telenor
4 problemsFlex-desk, temperature, toilets, coffee
Easy deployment2 gateways
devices are wireless perfect for existing buildings
Facility managementAuto-dispatches coffee-repair people

Lot of work
but where?Gateways just forward...
so... we need a networkJan and Olav went building something
Tech stack
Multiple basestationsNo gateway pinning
Gateway -> NetworkDe-dupe, data rate, join's, verify, etc.
EncryptionEverything end to end encrypted
Let's build a networkTake demo implementation from
Semtech and go from there
gateway #1
gateway #2
network server
AWS IoT
DynamoDB myMCS
Our problems are not uniquePrivate site, private network...
LoRa network server
as a service
LoRa network server
Telenor LPWAPrivate lora networks w/ click of a button
http://lora.cloud.tcxn.net:1880/nw/eiendom/
First client: EiendomMake it solid, then open up
We own the networkRoute networks over other gateways
Long term gain:
Next steps
Fornebu is open thru LPWA!So open for YOU!
Build end-deviceRegister on LPWA, and see data flow in
Trondheim team can help you build end-nodes
