LoRa = RF modules with a long range
Extraordinary price-attractive modules from company HOPERF Micro-electronics specializing to RF modules and a wireless signal transmission were introduced to you in our article HOPERF – universal RF modules for surprising prices.
This time we come with a novelty – module RFM95SW with a „LoRa“ suffix, indicating membership with a „Long Range“ family of modules. Long range of HopeRF LoRa modules is reached by usage of a modern efficient modulation with a spread spectrum, able to transmit data even on a noise floor level. RFM95W solves a traditional compromise among range, immunity (selectivity) and a power consumption while conforming to limits for usage in free bands.
LoRa modulation is quite complex and a user has a possibility to adjust all three main modulation parameters in order to fully meet requirements of a given application. These parameters are spreading factor, modulation bandwidth and error coding rate. For example if don´t need maximum transmission speed, we can set parameters so as to gain the highest possible quality and reliability of connection. By setting these three parameters we can choose an optimal combination for a given application.
RFM95W is ideal for OEM products with higher production series, where development costs usually get quickly refund also thanks to a very affordable price of these modules.
