LoRa = RF modules with a long range

Modern spread spectrum modulation enables HopeRF LoRa modules to communicate on a long-distance or in severe environment.
This is an archive article published 08/06/2019. Some information may no longer be up to date and in line with the current state. Please contact us in case of interest.

Extraordinary price-attractive modules from company HOPERF Micro-electronics specializing in RF modules and a wireless signal transmission were introduced to you in our article HOPERF - universal RF modules for surprising prices.

This time we would like to remind you of the module RFM95SW with a „LoRa“ suffix, indicating membership with a „Long Range“ family of modules. The 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 power consumption while conforming to limits for usage in free bands.

LoRa modulation is quite complex and a user has the 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 the 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.

Detailed information will provide you the RFM95SW datasheet. To make development easier, the RFDK_RFMxx starter kit is also available (upon order).

In case you are interested in any HOPERF module, please contact us at sales@soselectronic.com.
