RN2483 (433/868 MHz) LoRaTM Modem Long-Range, Low-Power Wireless Solution Summary The RN2483 is a LoRaTM-integrated modem with a range of more than 15 km (suburban), low power enabling a battery life greater than 10 years and the ability to connect millions of wireless sensor nodes to LoRa gateways and IoT-connected Cloud Servers. This robust system is due to LoRa's unique spread-spectrum based modulation that is capable of demodulation 20 dB below noise level. This enables high sensitivity for ultra-long range, improved network efficiency and eliminates interference. The RN2483 modem operates over the 433 and 868 MHz license-free Industry Scientific and Medical (ISM) frequency bands and serves as the end-device in the LoRa network infrastructure (see Figure 1). The RN2483 has the complete LoRaWANTM protocol stack on the modem and is easy to configure via simple ASCII commands through the UART, greatly reducing development time. The RN2483 is European R&TTEcertified, saving significant certification costs. Additionally, it combines a small form factor 17.8 x 26.7 x 3 mm with 14 GPIOs, providing the flexibility to connect and control a large number of sensors and actuators while taking up very little space. The RN2483 modem resolves the age-old wireless developer's dilemma to choose between longer range and lower power consumption. By employing the RN2483, you can now maximize both, while eliminating the cost of additional repeaters and increasing battery life. With its scalability, robust communication, mobility and the ability to operate in harsh outdoor environments, the RN2483 is well suited for a broad range of low-data-rate wireless monitoring and control designs.
