Connection tests for the LoRaWAN network are possible! Packet Error Rate (PER) measurements can be performed against this device.
The "WT-920" is a handheld testing device compatible with LoRaWAN in the specific low-power 920MHz band for the Japanese market. It can perform connection confirmation tests to existing networks as a LoRaWAN end device and measure the propagation characteristics of specific sections using LoRa modulation on its own. It is highly effective for preliminary investigations in network construction and for identifying causes during malfunctions. 【Features】 ■ Connection testing for LoRaWAN networks is possible (LoRaWAN device mode) ■ PER (Packet Error Rate) measurement can be performed against this device (PER measurement mode) ■ RSSI (Received Signal Strength Indicator) can be displayed in a list (Simple Spectrum Analyzer mode) In Simple Spectrum Analyzer mode, it also supports SIGFOX and other modulations besides LoRa. ■ GPS location information can be recorded along with RSSI measurement results. ■ Data can be saved to a memory card with a maximum capacity of 2GB, allowing for the creation of area maps on a PC and checking usage rates by channel. *For more details, please refer to the PDF document or feel free to contact us.

Company information
Founded in 1950, Oi Electric has realized many developments, including the pocket bell (1963) and desktop calculators (1963). The challenge spirit of the engineers at that time has been passed down to the current engineers, and we will continue to contribute to the development of social and communication infrastructure. If you are thinking, "I need something more than a generic product," "developing this will be costly," or "is there a product like this?" we would appreciate your contact. After listening to your needs, we will propose products that match your requirements. Our strength lies in developing high-quality products that can only be made through domestic production.
