LoRa module 2400 MHz

LoRa-2400-MHz coverage

The comparison of the range of a LoRa module with 2400 MHz, Bluetooth long range modules and LoRa 868 MHz modules shows that BLE long range is not a real long range. LoRa 2400 MHz with SF12 is not much worse than LoRa 868 MHz. LoRa 2400 MHz is not subject to any duty cycle. […]

Internet of Things Case Study – Street lights

Internet of Things Case Study – Street lights - Power station in Hanover

In Patras, Greece, they work on smart city technology development using NB-IoT has started. But how can the developers avoid the need for a SIM card and its subscription? Technical needs The smart lighting controller, for example, has been sending one status update message of 40 bytes every five minutes and a message containing energy consumption […]

Low cost BLE-GPRS-GPS-gateway

Bluetooth-GPRS-GPS-gateway

Are we able to make a mint of money with such a low-cost BLE-GPRS-GPS-gateway? If yes then it makes sense to follow a train of thoughts listed in my IoT M2M Cookbook. Everybody can make such a gateway real for less than USD 15. In my IoT M2M Cookbook – excerpt here: http://www.gsm-modem.de/M2M/m2m_iot_cookbook I explained […]

All in one wireless module =>NB-IoT (LTE-Cat-NB1), LTE-Cat-M1, GPRS and GNSS (GPS, Glonass)

NB-Iot, LTE-Cat-M1, GPRS, GNSS module on radio adapter with Arduino header

A dream came true. Within the last days, NB-IoT is moving in big steps. Orders for a new combined module on NB-IoT (LTE-Catt-NB1), LTE-Cat-M1, GPRS and GNSS (GPS, GLONASS) are welcome. If you miss NB-IoT or Cat-M1 for now, then just use the GPRS radio inside the module. Requests for data sheets, orders for samples […]
