Which connectivity option is best?

It depends on the site. LoRaWAN suits large estates and sites without easy network access; Wi-Fi suits offices already covered by enterprise wireless; cellular suits remote or single-asset deployments. Most portfolios end up mixing them.

How is sensor data kept secure?

Reasonable practice includes encrypted transport (TLS), authenticated devices, role-based access on the platform, audit logging and a clearly documented data residency policy. Specific assurances should always be verified against the platform's published security documentation.

Connected monitoring

IoT air quality monitoring — connected sensors, cloud platforms, scalable estates

IoT air quality monitoring is what makes single-site instruments into a portfolio-scale capability. Wireless sensors, secure connectivity and cloud platforms turn raw data into ongoing operational intelligence.

Capabilities

What an IoT monitoring platform brings

Remote access

Live and historical data accessible from any authenticated device, anywhere.

Device management

Centralised firmware updates, calibration coefficients and configuration push.

Alerts

Threshold breaches escalated by email, Teams, Slack or ticketing integration.

Scalability

Add buildings, zones or sensors without rebuilding the platform.

Connectivity

Choosing how sensors talk to the platform

LoRaWAN is well suited to multi-storey buildings and campuses. Battery sensors can run for years with minimal infrastructure beyond a small number of gateways.

Wi-Fi works where enterprise wireless is already universal. It removes the gateway question but consumes more power and requires careful network and authentication management.

Cellular is the right answer for isolated assets, remote sites or short-term deployments where no local network exists. Modern low-power 4G modules now make this viable at sensor scale.

Comparison

Connectivity options at a glance

Option	Range	Power profile	Best suited to
LoRaWAN	Hundreds of metres in-building	Years on battery	Estates, campuses, retrofit
Wi-Fi	Per access point	Mains-powered or short battery	Offices with strong wireless
Cellular (LTE-M / NB-IoT)	National coverage	Months to years	Single assets, remote sites
Wired (PoE)	Per cable run	Mains	New-build, refurbishment

Practical notes

What to insist on

Encrypted transport

TLS between device and platform; mutual authentication where supported.

Data export

Open APIs and exportable raw data so the platform cannot lock the estate in.

Documented residency

Clear statements on where data is stored and processed, and which third parties touch it.

FAQ

IoT air quality monitoring questions

It means each sensor is a connected device reporting independently to a cloud or local platform, rather than a standalone instrument requiring manual download. The result is continuous data, central management and remote access.
