Most health wristbands are designed for fitness enthusiasts who charge them every night

The B2315 was designed for people who can't be relied on to charge anything — the elderly with memory loss, hospital patients, construction workers at the end of a double shift. It does not assume compliance. It detects it.

The wear-detection sensor is the most important feature you won't see. The B2315 knows when it's on a wrist and when it's been removed. Both events are reported to the platform and the caregiver app. If a dementia patient takes the band off at 2 AM, the system knows immediately — not when a nurse notices during morning rounds. When the band is off-wrist, it drops into ultra-low-power mode, stretching standby beyond 20 days.

Two power modes, no guesswork

* Reporting interval is adjustable from 1 minute to 24 hours via the cloud platform. Off-wrist standby exceeds 20 days.

And when cellular signal drops — in an elevator, a basement ward, a concrete stairwell — the B2315 stores data to its 1MB onboard flash and dumps the buffer when it reconnects. No data holes, no gaps in the audit trail.

Positioning that bridges indoors and outdoors

Outdoor, the B2315 uses GPS + BDS (BeiDou), with WiFi and cellular LBS as fallbacks. Indoor, it scans BLE beacons. Deploy beacons at 6–8 meter spacing and you get 1–3 meter room-level accuracy. Add an AoA (Angle of Arrival) Bluetooth gateway, and accuracy tightens to under 1 meter — enough to distinguish which side of a hospital bed a patient is on.

This matters for elder care facilities where residents move between garden (GPS), common room (WiFi), and private room (BLE). One band, no mode switching required by the wearer.

B2315G vs B2315P: The only difference that matters

Both are 4G Cat.1. Both carry GPS/BDS, WiFi, BLE, heart rate, temperature, blood pressure, step counting, and sleep monitoring. The P model adds one sensor and one analytics module:

What the B2315 is NOT (honest limitations)

Real deployment: 200 residents across a dementia care facility

A 200‑bed memory care facility in Florida deployed B2315P bands to every resident. The primary requirement was not location — it was knowing when a resident removed the band. In the first three months, the system logged 47 off-wrist events, of which 31 occurred between midnight and 5 AM. Caregivers were alerted within minutes. Previously, missing bands were often discovered the next morning during dressing rounds. The facility also used BLE beacons in hallways and common areas to provide room‑level location (1‑3 meters), reducing the time spent searching for wandering residents by 70%.

Another client, a home healthcare provider in the UK, deployed B2315G bands to 500 elderly clients living independently. The long standby mode (8‑10 days) meant nurses could visit once a week to check on the band, not daily. The wear detection feature became the primary compliance metric — families could see in the app whether their parent was wearing the band.
