Not all 4G devices support LTE-A, and manufacturers usually don't give clear information if it is supported by your model, hence I want to know if there is any way to test this.
Thanks.
For those who are new:
The LTE-Advanced is an extension of regular LTE, it uses 'Carrier Aggregation' technology & multiple antennas on both BTS & Mobile devices to pump in more data per instance, allowing at least 3 times faster LTE speeds.
Top networks around the world are testing / deploying LTE-A in major cities, with speeds crossing 42 Mbps in real scenarios.

I have bought a new phone, but looking in cpu-z, only 4 cores are active, out of 8. The CPU chipset is HiSilicon Kirin 620 and I have read that other set of 4 cores kick in when needed, is this true? Other set of 4 CPU shows as stopped.
Yes. It is true and also sometimes few cores(low performance cores) are designed to be used in Saver Mode when battery is less..

I have a Motorola Razr D3. I was thinking about the possibility of use my cell phone like a FM Transmissor, so i can send a music in FM waves to my Radio in my car. Is it possible? Exist any app for it?
Is it possible?
Only if your device has dedicated FM transmitter hardware or is a software-defined radio device. Statistically speaking, it is very unlikely that any device that you own meets one of those criteria.

I understand that the Google Glass is currently equipped with the SiRFstarIV GSD4e GPS engine.
Does anyone know the horizontal (for my purposes) accuracy of GPS readings? (i.e. within meters)
Thank you
The expected accuracy is in all recent GPS chips about 2-3m in 95% of cases.
And like all chips in some cases up to 30m (or more) location error.
I have not tested it, but as long they did not made a horrible GPS antenna design flaw, the value will be very near to that.

In android, is it possible to limit the the number of the devices that are connected to the phone via tethering?
The limit by the OS is 10 , is there a way we can reduce this value through an app ??
Or is there a way to restrict the bandwidth of the tethered connections?
thanks in advance
No and no, respectively. A custom build of the OS, installed via a modded ROM, presumably can do this.
Yes, you can by using third party Apps like WiFi Tether for Root Users. This apps will allow you to select which devices can use your mobile-data connection.

Is it at all possible to get 2 Android handsets to see each other using the wireless interface? I'm not talking full-blown access-point mode. It would be cool if both devices could be actively looking for networks / devices whilst at the same time being 'discoverable' to other devices.
Is this possible in any way?
Thanks
Martin
Sounds like you want peer-to-peer ad-hoc networking which is not currently supported in Android. See Can Android do peer-to-peer ad-hoc networking? and http://code.google.com/p/android/issues/detail?id=82
If both devices have NFC chips and are really close (few cm) then doing the discovery with NFC might be an option for you.
