LightSquared and SI Wireless announced a partnership Thursday that will give SI Wireless customers access to LightSquared’s 4G-LTE broadband network and satellite coverage.

The bilateral roaming agreement also delivers 3G coverage to parts of rural Illinois, Kentucky and Tennessee.

The announcement follows a similar deal LightSquared and Cellular South announced Wednesday, which also expands the company’s coverage to rural communities.

“SI Wireless’ plan to deliver wireless services throughout rural underserved markets underscores LightSquared’s vision to provide universal broadband connectivity throughout the U.S.,” said Sanjiv Ahuja, Chairman and CEO of LightSquared in a statement about Thursday’s deal.

LightSquared has made several recent deals in its push to expand its 4G market, including agreements with Best Buy and Leap Wireless.
