As with physical dimensions, we'd call the communications capabilities between Apple and Samsung close to a draw, with a slight edge going to Apple because its carriers are known; Samsung has not yet announced carriers for Galaxy Note 10.1. Both devices offer HSPA+ and GSM/EDGE/GPRS network-capable radio options, both offer Wi-Fi a/b/g/n and Bluetooth 4.0. As for sensors, both offer a gyro, accelerometer, ambient light sensor, GPS and digital compass. The version of iOS released with the iPad 3 allows it to be configured as a Wi-Fi hotspot for as many as five devices. Samsung offers device-to-device connections with Wi-Fi Direct, and channel bonding to increase Wi-Fi throughput.
