According to NPDs monthly "Mobile Phone Track" service, following are the top four smartphone 4G manufacturers (OEMs), based on consumer sales in Q2 2011:
HTC remains far and away the 4G-smartphone-share leader, comprising 62 percent of the 4G-smartphone market. In the second quarter (Q2) of 2011, the company also had the top three best-selling 4G-smartphone models on three different carriers: EVO 4G, Inspire 4G, and Thunderbolt. Sprint boasts the highest percentage of 4G smartphone sales; and is the only carrier for which 4G handsets comprised the majority of smartphone sales. NPD considers smartphones to be 4G if they support LTE, WiMAX or HSPA+ with downlink speeds of 14 Mbps/s or greater.
"Carriers have chosen to market 4G with different tradeoffs for handsets," said Rubin. "While HSPA+, for example, has not achieved the fastest wireless speeds in the market, it has allowed carriers to build portfolios quickly with benefits for form factors, battery life and price."
