The latest update on Googles Project Ara

After Google has released its Aradebuted Project, users have been curious about the possibility of a customized smartphone with interchangeable modules. Also, it has been into the spot light the possibility of varying functionality that can be switched depending on the user`s needs.

For the moment, Google is concentrated on creating the Spiral 2 device.

This is a new variant of the hardware that will incorporate various modules, amazing flexibility, the possibility to change the battery while the device is on low power mode and the chance to work with multiple antennas for a better signal sourcing and various carrier approvals. Also, Spiral 2 changes from Field Programmable Gate Arrays ( FPGA) to ASICs. ASICs are specific application integrated circuits that provide superior performance and usually low power usage when compared to FPGAs.

Although, Spiral 2 has some issues with signal degradation over long term usage and some problems with the framework used to link different types of modules. Google is constantly working on induction signaling. They plan to use a 150 micron space between components in order to avoid the wear and tear that comes with constant changing. It is said that these improvements will be seen in Spiral 3 which will provide some extra RF field updates as well.

The roadmap of Project Ara

For the beginning of this new year, Google offered the Project Ara longer-term roadmap, which is estimated to have a market test by the end of 2015.

For Spiral 3 it will be used the Rockchip related design, an LTE 4G modem, and Android release, packaging and decorating updates and an all new framework for software advancement. This new framework is meant to provide an easy way for software and hardware developers to establish their projects. Google referred to the concept of offering innovative and not common battery design through a forum meant for experimenting with Project Ara. It is known that there are available battery technologies that provide tremendous improvements, but they are too expensive for typical insertion into smartphones or need some other basic requirements. Some of these impediments are expected to be met within the Project Ara modular concept. Google hopes that the platform will be used for prototyping and market testing.

The purpose is to obtain an initial pool of 20 to 30 modules. So, Google did not offer details on what a `pollution sensor` might be, but we can guess that it can include a carbon monoxide, carbon dioxide and other types of smoke detectors modules. A Project Ara device will probably have different modules to scan for different types of atmospheric contaminants.

Google affirmed the fact that the purpose is to establish an entire ecosystem around this concept and not to offer it directly to the consumers. Although, it is not clear if the vast consumer space will be available on the device, but the modular purpose may get popular with hobbyists that want the ability to set up the phone for certain long time battery life or for specific sensors.

Google estimates that if the test go as planned, this will be available next year in 2016.
