IT Networking: Code Division Multiple Access (CDMA) (Research Paper Sample) Content: IT Networking: Code Division Multiple Access (CDMA)Name of studentName of institutionName of instructorCourseDate dueIT Networking: Code Division Multiple Access (CDMA)The Code-Division Multiple Access (CDMA) is a protocol used in wireless communication particularly in the second and third generation. In addition, the CDMA is not only a channel access technique but also a type of multiplexing that permits a number of signals to utilize the available bandwidth. The CDMA is also appropriate in ultra-high-frequency (UHF) mobile phones. Conversely, the CDMA uses analog to digital conversion (ADC) as well as spread spectrum technology. However, audio inputs have to be converted from digital to binary elements. The transmitted frequency is also made in a way that it varies based on the code. This is basically done to ensure that it can intercept the receiver with matching code and follows the transmitter frequency. Owing to the fact that there are countless codes, privacy is enhanced while making cloning extremely difficult. The initial CDMA standards are widely used in cellular phones in the United States and present a transmission speed of approximately 14.4 kilobits per second (Kbps) in a single form and more than 115 Kbps in an eight channel form. This technology is, therefore, effective in transmitting confidential information as no external party can disrupt with the information, see or even receive the broadcasted messages. This is attained through the use of unique codes for each person.Comparing CDMA to other SolutionsCompared to other solutions like GSM, the CDMA depends on the network-based white list in the verification of users. This implies that users can only switch phones with carriers approval; as such carriers do not have to accept certain phones in their networks. On the other hand, GSM allows easier swapping of phones since carriers put users information on removable subscriber identity module (SIM) cards. However, GSM carriers ha ve to take the GSM-compliant phone, hence; they do not have full control of users phone. Furthermore, GSM has a high-speed wireless data General Packet Radio Service (GPRS) provides slower information bandwidth for wireless connectivity compared to CDMA high-speed tool; 1xRTT with the ability to offer Integrated Services Digital Network (ISDN) at a speed of 144 Kbps. Nonetheless, 1xRTT requires a special connection to the network, GPRS transmits the packet. This, therefore, implies that GSM phones do not block voice calls like CDMA handsets.Strengths and weaknesses of CDMAThe CDMA has the ability to provide reliable transmission mechanism for data transfer including internet traffic, telephone traffic capacity, and facsimile. In addition, this technology can enhance voice quality while eliminating audible and effects associated with multi...
