An easy way to increase the densification to :

Connect additionnal objects

Connect inhome appliances

Enhance the accuracy

LoRa in the Home residential GWY :

Plugging a module on existing Home residential

Gateway via existing USB interface.

LPWAN IoT Systems Now & Tomorrow

LPWAN are changing already the rules of competition by

proposing new disruptive business models, thanks to tailored

technology, well dimensionned from the beginning with the true

fondamental and simple primary needs from major industrial

IoT:

- (Very) Low Power

- (Very) Long Range

- (Very) Low Cost (TCO)

This allows new actors to join the Connected Economy, by

adopting available & affordable wireless technology, with simple

& fast roll-out.

Simplifying IoT roll-out will massively

benefit value extraction from data, and

its monetization.

Innovative & disruptive business is emerging from ISM bands

technologies (e.g. WiFi, RFID, SRD, and now IoT), Regulators

should bear that in mind, whilst LTE-U/LAA is crossing the line
