# LTE Discovery

> LTE Discovery is an Android cellular signal analyzer and the publisher of the LTE Discovery Coverage Intelligence API ("Coverage API"): measured LTE and 5G NR coverage and signal data from real phones, per carrier and band, on H3 hexagons. US only.

The Coverage API reports crowdsourced, de-identified measurements: RSRP, RSRQ and SINR statistics with reading counts, band deployment by market, cell identity and channel data (not site locations), a paired-cell network benchmark and, on paid plans, raw measurements. Density varies by area; results without enough readings are reported as insufficient evidence, not as no coverage.
