Skywire® 4G LTE CAT 1 AT&T -WNC Embedded Modem
NimbeLink’s 4G LTE CAT 1 WNC modem for the AT&T cellular network. Designed for IoT and M2M applications, this embedded modem offers the lower price and speed of obsolete 2G technology with the long life and capabilities of the modern 4G LTE CAT1 network.
Based on an Altair chipset, the Skywire 4G LTE CAT 1 embedded modem, and its Skywire Verizon companion model are the first Cat 1 LTE modems with FCC and carrier-required end-device-certifications. End-device-certification eliminates months of testing and tens of thousands of dollars in cost and helps speed products to market.
Like other modems in the NimbeLink’s Skywire family, the LTE CAT 1 modem is the smallest in the industry and is compatible with a variety of NimbeLink development kits and microprocessor shields, for fast, easy integration of cellular connectivity into new and existing products. It also shares the Skywire standard interface with all other modems in the Skywire family, ensuring long product life. Its U.FL ports provide antenna flexibility, and the modem requires just voltage and a serial UART or USB connection. It supports a wide range of voltages for design flexibility.
