LoRa 2.4 GHz RF Modules

& Border Routers

LoRaWAN-independent network that gives you freedom like no others can, that can be easily connected to our IoT service platform or your own either on the cloud or on premise.


LoRa 2.4GHz

How Did It Come About?

Depending on the needs of IoT service, you can choose from endless options to wirelessly connect the Internet of Things. However you must compromise on your priorities. For example, is fast data rate most important for your service? Or long range? How about power consumption or security?

IoT applications typically communicate small amounts of data. As a trade-off for low bandwidth, LoRa was born to communicate data with energy efficiency, security, and robust signal for long ranges, which makes LoRa the best choice connectivity for IoT applications.

LoRaWAN? Or Private LoRa?

However applications communicating using LoRa technology must use LoRaWAN network, which is public infrastructures built and managed by network operators. This means stability, flexibility, and security of your IoT service will be dependent on the mercy of the network operators. Your data will be shared on the network operator's servers, and you also have to pay recurring subscription (usage) fees. And LoRaWAN network is not available in most areas in the USA.

The good news is...

iotair, IoT Builder's LoRa 2.4GHz connectivity solution, is LoRaWAN-independent and enables private networks without LoRaWAN gateways. If your priorities are long range, low power consumption, high reliability, and flexible network, we have a perfect solution for you.
