3G and 4G are wireless technologies, which are supposedly faster, more secure and reliable. Present day 3G technology is capable of handling data around 2 Megabits per second (
1.8 -
2.5 GHz frequency band). What speed is expected from new 4G technology ?

{'gigabits': [0, 0, 0, 1], 'ghz frequency band': [0, 0, 0, 2], 'wireless technologies': [0, 0, 2, 1], 'speed': [0, 1, 2, 0], 'megabits': [0, 0, 0, 1]}

The correct answer is option 3. The expected speed from the new 4G technology is between 100 Megabits per second and 1 Gigabit per second. This is a significant increase compared to the 2 Megabits per second speed of the current 3G technology.

Option 1 states that the expected speed is 10-30 Megabits per second, which is not as fast as 4G technology.

Option 2 states that the expected speed is 10-100 Megabits per second. While this is within the range of the expected speed for 4G, it does not specify the frequency band accurately.

Option 4 states that the expected speed is more than 10 Gigabits per second. This speed is significantly higher than what is currently expected from 4G technology.

Therefore, the correct answer is option 3, as it accurately describes the expected speed range for 4G technology.
