Samsung Z: Move Over Android, It's Time For Tizen


Communications

The Samsung Z radios include Wi-Fi a/b/g/n (but no ac), Bluetooth 4.0, NFC, Infrared and LTE 4G with backward compatibility with 3G and 2G networks. The device also includes GPS and GLONAS receivers and  sensors for acceleration, gyroscopic movement, proximity, compass direction, barometric pressure, ambient light and heart rate. There's also a magnetic hall sensor for accessories and a fingerprint scanner. This list is virtually identical to that of the Galaxy S5; the S4 leaves off a few. Samsung also includes a feature it calls Download Booster, which bonds 4G and Wi-Fi channels to create a 450-Mbps connection to quicken bursty apps and large downloads.
