12、essity in the same manner as mobile voice did just a few years ago,it promises to be a major piece ofthe puzzle for service providers.,Because so many subscribers currently rely on second-generation mobile technologies,there is a long way to gobefore 3.5G+and LTE networks are the norm.With such majo

17、idth during periods of peak bandwidth utilization,At the core of successful mobile Internet strategy is sufficient data to make informed decisions regarding service plans,management policies,capital investments and premium services.Service providers have long since had access todetailed information

38、providers,but the Internet service is still delivered through the air.The same is true forproviders of satellite Internet,who are known for servicing areas where laying wires is cost-prohibitive,but haveincreasing presence in traditional broadband strongholds.Providers of WiMAX(802.16e-2005“mobile W
