Windows 8 tablets Hardware Certification Requirement documents reveal features

Earlier in December, Microsoft had released documents titled Windows 8 Hardware Certification Requirements. If you visit this page, accept the License agreement to access these documents, you will see 3 sets of PDF documents:

These documents are in fact a big source of interesting information. If you go through these documents, you can get an idea of what kind of features a Windows 8 device, tablets or PCs are expected to have. These requirements are also mentioned for the new generation of ARM based devices supporting Windows 8.

A Windows Certified System is composed of Windows certified components. These internal devices are certified before system integration.

Let us check some of the interesting features that might be preset on these devices. We'll be looking at them from the Windows 8 Tablet point of view, as Windows 8 certified tablets are yet to hit the market.

Some of the interesting points are:

Bluetooth : If a system includes a Bluetooth controller it must support the Bluetooth 4.0+LE specification requirements.

Digitizer : Pen feature for digitizer

UEFI : Systems might implement Unified Extensible Firmware Interface (UEFI) instead of BIOS for Secure Boot.

NFC : Near Field Proximity is a set of short-range wireless technologies to enable communication between a personal computer and a device. Any Windows 8 device providing  this Near Field Communication (NFC) Technology should provide some visible Touch Mark to help users locate and use this proximity technology.

“If the system has a proximity technology then there must be a touch mark to indicate where to tap devices together.”

“When tapping two devices together with two tablets, both tablets should line up the radios with each other (meaning the upper right quadrants are lined up) and then a successful tap will occur.”

“When tapping two devices together, a connection cannot be established if the touch point of the host device is greater than 10 cm away from the other touch point. “

Accelerometers : Accelerometer are required to adjust to the screen rotation - when a user rotates a device from landscape to portrait and vice versa. All Windows 8 systems with an accelerometer must have sufficient graphics performance to meet performance requirements for screen rotation.

Various Sensors: All or some of these sensors might be integrated into Windows Sensor platform - Human proximity sensor, 3D Accelerometer, 3D Inclinometer, 3D Compass, 3D Gyrometer, Ambient Light Sensor.

Minimum required components to be present in a Windows 8 tablets in order for it to be certified for Windows 8.

Let us see this in detail:

As you can see in the above table, at least 10GB of storage space to be available after the install. So can we expect 16GB ARM devices? The minimum screen resolution is 1366X768

Webcam - Front or rear facing camera integrated in the system needs to support scenarios such as taking a photo, recording video or real-time communication.

And all these features are given the Enforcement date as Windows RC . So one can expect Some of the Windows 8 Tablets including ARM devices to be ready at least in prototypes at the release of Windows 8 RC

These are some of the features that have been posted from a very detailed document provided by Microsoft. For a detailed look, please check out the Windows 8 Hardware Certification Requirements documents.
