The Carmel Valley company filed documents with U.S. securities regulators on July 15, saying it planned an initial public offering. Airgain plans to sell up to $17.25 million in stock, judging from the estimate it made for its registration fee.

Airgain reported sales of $27.8 million in 2015, up from $25.5 million in 2014. The business has 48 employees, including 10 in China and five in the United Kingdom.

The company said it wants to list its shares on the Nasdaq under the symbol AIRG.
