UPGRADED CALIBRATION AND EXTENDED BANDS
The GPy is our Micropython-programmable triple bearer. Different from its SiPy counterpart, the GPy offers WiFI, BLE and cellular CAT-M1/NB1. Create and connect your things everwhere.
**IMPORTANT NOTE: As of December 2019, all our cellular products have been recalibrated and screened on all 17 bands with a vastly improved RF test system to guarantee more stable connectivity, lower power consumption and faster network attachment.
New specialised equipment and software from Rhode & Schwarz enables us to do more precise measurements during the calibration process. This enhances RF sensitivity and thus signal quality especially in areas with poor cellular coverage while reducing output power during transmit to improve battery performance.
Get on with a board that gets you into the newly available LTE CAT M1 / NB1 networks. The GPy gives you full flexibility during testing, install, deployment and is delivered RCM, IC, CE and FCC certified.
NOTE: The Cellular Antenna MUST always be used with LTE CAT-M1/NB1 or the board could become seriously damaged.
