4G + Bluetooth Module YOOAI-WB4G
Standalone 4G cellular networking and Bluetooth local control for commercial water purifiers
The 4G + Bluetooth module YOOAI-WB4G is the communication module of YOOAI water purifier rental solution, integrating 4G cellular and Bluetooth dual-mode communication. 4G connects devices independently to the cloud IoT platform - no on-site WiFi needed for remote control and data reporting - while Bluetooth handles on-site near-field control and debugging. Platform access data service fee and traffic fee are charged annually, fitting bulk deployment of commercial water purifiers in no-WiFi environments.
Core Features
Standalone 4G Cellular
Built-in 4G communication - insert an IoT SIM to connect independently to the cloud platform with no on-site WiFi or router, ideal for instant networking of commercial water purifiers in no-network environments.
Bluetooth Local Control
Retains near-field Bluetooth control so maintenance staff can debug devices, read status, and configure parameters on-site without relying on any network.
Annual Service Fee Model
Platform access data service fee and 4G traffic fee are charged annually per IoT terminal - transparent and predictable, enabling brands and agents to budget long-term operating costs.
Use Cases
- Commercial offices, chain restaurants, and public spaces without WiFi deploying water purifiers
- Commercial water scenarios needing standalone cellular plus on-site Bluetooth debugging
- Scattered multi-site deployments requiring remote unified management and bulk shipment
Selection Guide
If the deployment site has no WiFi or needs fully independent networking, the 4G + Bluetooth module YOOAI-WB4G is the recommended choice; if WiFi is stable, the Wi-Fi + Bluetooth module YOOAI-WBC3 is more cost-effective with no annual traffic fee; if only 4G connectivity without Bluetooth is needed, evaluate the 4G comm board BL-600N.
FAQ
How are platform access and traffic fees charged?
The platform access data service fee and 4G traffic fee are charged annually per IoT terminal - transparent and predictable for long-term cost budgeting. Contact sales for specific pricing.
Do I need to buy my own IoT SIM?
The module supports standard IoT SIMs - use a carrier IoT card or a regular data card billed per carrier rates, or consult YOOAI for a bundled IoT SIM solution.
Is 4G data usage high?
Water purifiers report very little data (power on/off, TDS, water volume, filter status, alerts); monthly usage is typically within tens of MB, so cost is very low.
