[amp_mcq option1=”Eight” option2=”Sixty four” option3=”Sixteen” option4=”Twenty five” correct=”option1″]<\/p>\n
The correct answer is: A. Eight.<\/p>\n
IS-95 is a digital cellular technology that was developed by Qualcomm. It is also known as CDMAOne or cdma2000 1x. IS-95 uses a spread spectrum technology called Code Division Multiple Access (CDMA) to allow multiple users to share the same radio frequency channel. CDMA works by spreading the user’s signal over a wide range of frequencies. This makes it difficult for other users to interfere with the signal.<\/p>\n
IS-95 can support up to eight users per 1.25 MHz channel. This is because CDMA is a very efficient way to use radio spectrum. It is also because IS-95 uses a technique called power control to ensure that all users have a good signal. Power control adjusts the power of each user’s signal so that it does not interfere with other users.<\/p>\n
The other options are incorrect because they do not represent the number of users that can be supported by IS-95 per 1.25 MHz channel. Option B, sixty four, is incorrect because it is too high. Option C, sixteen, is incorrect because it is too low. Option D, twenty five, is incorrect because it is not a multiple of eight.<\/p>\n","protected":false},"excerpt":{"rendered":"
