The world of mobile never stops moving, and one of the most important drivers of mobile’s continued evolution has been the constant improvement in wireless connectivity. This has been dramatically improved with the advent of 3G and LTE, but LTE is starting to see its limitations, and we are starting to see a need for LTE-A or LTE-Advanced, which utilizes an important feature called “carrier aggregation” to increase speeds. Think of carrier aggregation as combining multiple, smaller bands of spectrum into one bigger band. Carrier aggregation is quickly becoming the next step forward for 4G connectivity and operators around the world have deployed or are testing their networks to deploy LTE-A networks with carrier aggregation. This presents an opportunity for smaller operators to compete with their larger competitors in speeds and smaller OEMs to beat their larger competitors to addressing the need for devices with carrier aggregation. Unfortunately, carrier aggregation hasn’t quite taken up everywhere around the world equally.  In fact, U.S. carriers AT&T, Sprint Corporation, T-Mobile U.S. and Verizon Communications are lagging a bit in carrier aggregation deployments which is odd given the U.S.’s early lead in LTE.
