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
