Connectivity platform is required to support 2 or 3 generations of network
equipment & 3 or 4 generations of CCTV cameras or AV displays
Premises Cabling
n Optical backbones
– OS2 single-mode & OM5 multi-mode
– Diversely routed
– Overlay of Cat6a copper
n Horizontal or floor cabling
– Cat6a copper - 10G & 100w PoE
– MPO optical - future 5G/6G support
n Ceiling grids
– 5m grids of 4 x Cat6a RJ45 outlets
– >12m grid for 1 x OM5 MPO
n Floor grids
– 1.8m grids of 2 x Cat6a RJ45 outlets
Expensive to deploy retrospectively – do it once and do it properly

Physically or logically distinct from the enterprise network
Enterprise grade switching fabric – consolidated OT/IT network
– Architectural resilience – 3 layer/dual core
– SDN based management & control
– Enterprise cyber security
n Optical core with PoE rich edge - <802.3bt type 4 device support
n Consolidated UPS, server & storage policy for site hosted apps
– Dedicated comms room(s) not riser cupboards
Enterprise grade wireless solutions
n WiFi6 802.11 ax access points
– 2.4GHz (IoT), 5GHz & 6GHz – frequency separation for security &
performance
– WAPs can support IoT (BLE, Zigbee & LoRa) but is this wise?
– Support for in-building location based services
n In-building cellular – small cell vs DAS
– 4G/5G multi-operator service via neutral host

8. IoT & Building Services (BIoT) Systems
A cloud first policy where
practical
n Technical & security
considerations
– Enterprise grade security
Policy goal
n Minimize the need for on-
site device maintenance &
upgrades
– Data analytics &
upgrades completed off-
site
n Limit technical complexity
of edge devices & sensors

10. BIoT Support & Maintenance Services
An integrated, smart, on-demand support service
n Support the huge increase in # devices
n Leverage deployment of remotely supported & cloud based
solutions
n Single, holistic site-based ‘things’ support contract
Technology asset tracking & management
n Technical: what, where, how it’s connected and when to
maintain/replace
– Single set of context aware building drawings
n Financial: optimise maintenance & refresh process
Understand the asset lifecycle and when its most cost effective to
refresh it.

BIoT as a Service Model: Built In Refresh
§ Maintenance plan aligned with
refresh cycle. Customer buys into
monthly charge model and all
hardware fixes taken care of,
assets procured and disposed of
ethically from cradle to grave.
§ All parties benefit from lower
fault calls and lower costs via
exercising extended product
warranties

14. Avoiding Technological Obsolescence
n Smart enablement – create a ubiquitous connectivity platform
– Physical connectivity
– Enterprise grade building network
n Cloud first IoT/building services system strategy
– Offload the risk associated with technological obsolescence to suppliers
n Implement and operate a proactive device support & maintenance
process
– Supplier is focused on the remote platform and the landlord/tenant on
maintaining the edge
– Understand the useful lifecycle of each asset group
n Consider BIoTaaS models
– Obsolescence risk removed entirely for a predictable monthly charge.
