Google has announced that it plans to launch a mobile phone network in the US, Project Fi, which will initially only be available to Nexus 6 handsets.

They will use existing wi-fi hotspots from two current mobile phone operators – Sprint and T-Mobile to give them a leg-up by using existing technology.
Other companies such as Comcast and Time Warner Cable have been encouraged to offer their customers a speed boost but without higher prices.

Ian Fogg from the HIS Technology consultancy said: "No-one would have thought that a handset manufacturer could transform the mobile industry by teaming up with one network - but that's what happened with Apple and AT&T when the iPhone launched.

"And Google itself has repeatedly shown that it is capable of changing the direction of an industry by entering it."

Google revealed that Project Fi will automatically flick between 4G signals via Sprint and T-Mobile, whichever is the strongest, and customers will be able to make calls using wi-fi without using an app.

Google commented on their blog saying "As you go about your day, Project Fi automatically connects you to more than a million free, open wi-fi hotspots we've verified as fast and reliable," adding "Once you're connected, we help secure your data through encryption. When you're not on wi-fi, we move you between whichever of our partner networks is delivering the fastest speed, so you get 4G LTE in more places."

As it stands, Google are not planning to branch out to other models and have limited the access to invitees only.
