2G is the communication technology intended to provide the mobile communication over voice and 3G is a specific one with enhanced capabilities to provide facilities other than voice to mobile users. a. CDMA b. TDMA c. SDMA d. FDMA. This modification has a strong impact on positioning capabilities. Which of the following multiple access techniques are used by second generation cellular systems? You'll be eligible for federal aid. These are interesting times because it is rare that the communications industry rolls out a new modulation format. 2. Online Mcqs Test – Mobile Computing MCQ with Answers. a) IS-136 b) GSM c) PDC d) AMPS View Answer. Medigap vs. Medicare Advantage plans offer different options. Hence, we must somehow, allow multiple users communicate in the same frequency range. People create a picturistic view in their mind after viewing a model of particular thing and hence can explore it better. 1. (SC-FDMA). In SC-FDMA, throughput depends on how the information symbols are applied to the subchannels. Learn about their coverage and more in this article. a. CDMA. In case of mobile communication, which is a form of wireless communication, the only restraint on communication is the bandwidth restraint which means we have a limited frequency range that we can use for communication. Which of the following is NOT an advantage of digital modulation over analog modulation? The 2G networks are primarily used for the transmission over voice, whereas the 3G networks provide an additional advantage of data transfer. ... One of the advantages of _____ technologies is their conservative use of … Channel access schemes generally fall into the following categories. There are two possible implementation approaches to SC-FDMA: SC-FDMA with constraints (also known as localized SC-FDMA) and distributed SC-FDMA. One of the main advantages of TDMA over FDMA is that in FDMA, the earth station must transmit and receive on multiple frequencies to achieve a desired traffic plan. Advantages. B. Which one of the following is an advantage of setting up a family day care home? There are advantages over disadvantages for using models for the knowledge of world. Which of the following stores all the user-related data … Multiple Access Techniques are ways to accessRead More Online Mcqs Test – Mobile Computing MCQ with Answers-All these are very important MCQ questions related to mobile computing and mobile and wireless communication to get success in written as well as interview examinations. A. From both a technical and practical point of view, there is much to understand, examine and evaluate in the capabilities and benefi ts that SC-FDMA brings to LTE. In telecommunications, orthogonal frequency-division multiplexing (OFDM) is a type of digital transmission and a method of encoding digital data on multiple carrier frequencies. What is best for a person depends on their particular needs. Q1. The frequency-division multiple access (FDMA) channel-access scheme is the most standard analog system, based on the frequency-division multiplexing (FDM) scheme, which provides different frequency bands to different data streams. You can enroll as many children as you wish. C. You can obtain a tax-exempt status. a. better use of bandwidth ... FDMA. Frequency-division multiple access. Gsm in mobile computing. Which one of the following 2G standard is used in Japan? In SC-FDMA with constraints, each terminal uses a set of adjacent subcarriers to transmit its symbols. In a TDMA system, the needed selectivity is obtained in time rather than frequency. Due to the FDMA multiplexing scheme, the conventional CDMA observation model has to be modified to restore the integer estimability of the ambiguities. D. Your own child or children will have children to play with Which multiple access method uses a spreading code? SC-FDMA … The use of the GLONASS legacy signals for real-time kinematic positioning is considered. Fundamental types of channel access schemes.
