Blue Mountain Wireless is a start-up company located near picturesque Blue Mountain, part of the Appalachians, in eastern Pennsylvania. The company has broad and in-depth expertise in communications technologies, with an ongoing focus on wireless cellular networks.

Wireless cellular is a young industry with a long history. In the last two decades it has gone through several generations, and is now transitioning from 3G to LTE (long-term evolution or 4G), and then to LTE-advanced. LTE-advanced incorporates all that modern wireless communications technologies have to offer to grow the spectrum efficiency by leaps and bounds, and thus promises a future wireless cellular network that will be vastly superior to those of previous generations, and that will revolutionize the way people communicate, work, and live.

With great promises come great challenges. The future wireless cellular depends crucially on several key technologies whose feasible implementations have been elusive until now. Blue Mountain Wireless has been developing innovative breakthrough solutions to successful realizations of those key technologies. Moreover, our innovations extend to other wireless technologies, such as WLAN, which complement the wireless cellular in the universe of wireless communications.
