Our toolbox: network, radios, and compute
Point Loma Labs has several research efforts currently in work. A key capability for our IoT solutions is leveraging the right 5G protocol.
Bandwidth
NB-IoT uses a narrowband of 180 kHz or 200 kHz. The uplink NB-IoT carrier has a bandwidth of 200 kHz, with 180 kHz for transmission and 10 kHz for guard bands on either side.
Transmission power density
NB-IoT's narrowband bandwidth allows for a higher transmission power density, which improves its range. This makes it suitable for IoT devices in buildings, tunnels, basements, and other locations.
Deployment
NB-IoT can be deployed in a GSM, UMTS, or LTE network. It can also coexist with existing networks in three deployment modes: in-band, protection band, or independent carrier wave.
Use cases
NB-IoT is suitable for IoT devices that need to connect over long distances but don't need to send a lot of data. Some examples of use cases include smart meters, smart street lighting, parking sensors, HVAC control, industrial monitors, and agricultural sensors.
Summary
NB-IoT is a low-power network technology that's designed to be energy efficient and scalable. It can send data indoors and underground while using very little battery power.
Bandwidth
LTE-M uses a bandwidth of 1.4 MHz or 5 MHz
Transmission power density
LTE-M's is also designed for Machine-to-Machine connections It has higher bandwidth and lower latency, but consumes more bandwidth than NB-IOT, but much less than standard LTE connections. Estimates are that it is 80% less OPEX cost than using standard LTE.
Deployment
LTE-M can be deployed in a GSM, UMTS, or LTE network. It cannot be embedded in the bands like NB-IOT.
Use cases
LTE-M is useful for vehicles, containers, and machinery in real-time, even when they're moving. This can help with supply chain management, fleet management, and more.
Summary
LTE-M is a low-power network technology that's designed to be energy efficient and scalable. It can send data indoors and underground quickly for much less cost than standard LTE.
