Decision table
Data volume
- NB-IoT
- Small readings at longer intervals
- 4G LTE gateway
- Multiple sensors, files or frequent payloads
- Guidance
- Match network type to data rate and retry behavior.
Device topology
- NB-IoT
- One device reports directly
- 4G LTE gateway
- Gateway aggregates many field devices
- Guidance
- Use LTE when one site has several RS485 or IO points.
Deployment speed
- NB-IoT
- Depends heavily on operator support
- 4G LTE gateway
- Easier to pilot with standard SIMs
- Guidance
- Confirm bands, SIM and APN before sample order.
Hardware used in the comparison
Product-family photos; the model and enclosure may vary.
Choose NB-IoT when
- Single meter or sensor point
- Long battery interval is important
- NB-IoT coverage is already verified
Choose 4G LTE gateway when
- Several meters or sensors share one site
- RS485, Ethernet or IO needs aggregation
- The project needs quick field testing
Information needed for quotation
- Target country and operator
- SIM or APN requirement
- Number of connected devices
- Payload frequency and backend protocol

FAQ
How do I choose between the two options?
NB-IoT fits these conditions: Single meter or sensor point. 4G LTE gateway fits these conditions: Several meters or sensors share one site. SunGene can shortlist hardware after reviewing the site and integration details.
Can SunGene quote both options?
Yes. Send the site layout, measurements, available network and quantity. We can compare equipment and accessories for both options.
Does this comparison include pricing or guaranteed certification?
No. Pricing and certification depend on the selected hardware configuration and target country, so they are confirmed during quotation.
Can we test an option before a wider rollout?
Ask for a sample or pilot configuration. Agree the interfaces, power, mounting and receiving system, then compare local readings with the received data. Confirm model-specific documents and any required approvals before ordering.
