How many users are supported by Cdma2000 1X in comparison to 2G CDMA standard?

The correct answer is C. Six times.

Cdma2000 1X is a 3G mobile phone technology that can support up to 6 times as many users as the 2G CDMA standard. This is because Cdma2000 1X uses a different type of modulation, which allows it to carry more data on the same frequency.

Cdma2000 1X is also more efficient than 2G CDMA, which means that it can use less power to transmit the same amount of data. This makes it a good choice for mobile phones that need to conserve battery life.

Overall, Cdma2000 1X is a more advanced technology than 2G CDMA, and it can support more users and use less power.

Here is a brief explanation of each option:

• Option A: Half. This is incorrect because Cdma2000 1X can support more users than 2G CDMA.
• Option B: Twice. This is incorrect because Cdma2000 1X can support more than twice as many users as 2G CDMA.
• Option C: Six times. This is the correct answer because Cdma2000 1X can support up to 6 times as many users as 2G CDMA.
• Option D: Ten times. This is incorrect because Cdma2000 1X can support up to 6 times as many users as 2G CDMA, but not 10 times as many.
