. Gobi technology 2 was designed to allow for any product with the embedded solution to connect to the internet anywhere a wireless carrier provides data coverage. One of the more notable products that contain a Gobi modem is the iPhone 4 for Verizon, which contains a MDM6600, however it does not take advantage of the support for HSPA+.

History

On October 23, 2007, Qualcomm announced the first set of Gobi-enabled

capabilities and other software upgrades. The third, and most recent, generation of Gobi-enabled chipsets was announced on March 23, 2010 however this generation consists of a total of 6 different chips which support different ranges of wireless standards and data rates. The reasoning behind the multiple chips was to address additional markets such as
