Bluetooth Mesh vs BLE: What's the Difference for Large Deployments

Standard Bluetooth Low Energy typically connects one device directly to another (a wearable to a phone, a beacon to a receiver) with limited range — fine for a single pairing, but not designed to cover a large building or extend beyond a fairly short direct distance.

Bluetooth Mesh allows BLE devices to relay messages to each other, extending effective range across a much larger area — a large commercial building, a warehouse, a multi-floor facility — similar in concept to how Zigbee or Z-Wave mesh networks work, but built on the widely available Bluetooth radio hardware already in most modern devices.

It's increasingly used for large-scale commercial lighting control and asset-tracking deployments, where the goal is many small, low-power devices covering a wide area without the cost of installing a completely separate wireless infrastructure. This is worth knowing about specifically for large commercial lighting projects considering their control network options.
