‘smart city’ concept

280k nodes rolled out across the UK
100k additional installation underway
how can we leverage existing network to enable more applications?

‘smart city’ concept
existing architectures do not allow for low cost sensing
sensing often requires:
battery power (no mains)
low data rate (can do local processing)
duplicated communications functionality
©TTP 2015
©TTP 2015
‘smart city’ concept
utilise street-lighting network as transparent network layer
financial payback of network install by smart lighting
allows for very low cost/low power (non-meshing) sensors
