Mobile cloud startup Luminate Wireless has added a roster of big names, including Google Ventures and Qualcomm, to its list of investors ahead of Mobile World Congress.

The company, which was brought to the industry's attention by Light Reading in an exclusive story last September, had previously only identified Sequoia and NEA, which invested in 2013, as its backers -- both big names, of course. (See Exclusive: Luminate Wants to Light Up the Mobile Cloud.)

Now, though, it names the following additional backers:

The company declined to answer any questions about its newly named investors or discuss whether it had received any new funding, though industry sources suggest the company has now raised close to $50 million since it was formed in late 2013.

Light Reading had suggested in the September article that Google (Nasdaq: GOOG), a previous employer of Luminate Wireless Inc. 's CEO Murari Srinivasan, might be among the startup's financial supporters.

Armed with that investment calling card, the company is heading to Mobile World Congress to pitch its Mobile Cloud Controller software to companies looking for ways to quickly and easily add small cell capacity. Small cell strategies will become increasingly important to wireless service providers as they seek to build networks that are more "dense" in high-usage public and indoor areas, especially as video traffic continues to grow and the number of IoT devices connecting to public networks grows in the coming years.
