Verizon is a forerunner on multiple fronts. For starters, Verizon made a big bet on its FiOS fiber-optic to the home network. That network is now giving Verizon the means to compete with cable giants such as Comcast. Verizon's wireless unit is also a powerhouse. The company is working to roll out 4G Long Term Evolution (LTE) technology in an effort to leapfrog rival AT&T.
