- The ideal smart building and smart metering gateway
- CloudGate with LTE CatM1/NB1 modem
- Ethernet, M-Bus and serial interface
CloudGate nano was created with smart buildings in mind. The use of a LTE Cat M1/NB1 modem with high-power chipset ensuring better indoor coverage compared to traditional 2G/3G/4G modems, allows connecting devices deep inside buildings. By adding a Modbus and M-Bus connector it is possible to connect electricity, gas, water or calorie meters but also wired sensors that need to send data to a Cloud platform.
With the powerful LuvitRED program on CloudGate it is very straightforward to create the required data flow on the gateway or to perform edge processing on the data before it is sent to the Cloud. Data reduction through edge processing is vital in case of low bandwidth protocols such as CAT-M or NB-IoT to improve data performance and reduce connectivity cost.
NB-IoT supports ultra-low complexity devices with very narrow bandwidth of 180 kHz. Due to its narrow bandwidth, the data rate peaks at around 60 kbps. On the other hand, Cat-M1 operates at 1.08 MHz bandwidth with higher device complexity/cost than NB-IoT. The wider bandwidth allows Cat-M1 to achieve greater data rates and lower latency. The link budget for NB-IoT is also higher than for LTE Cat M1 and much higher than LTE Cat 4which means that coverage under difficult circumstances is best in Cat-NB1 mode.
