Editing Time-division multiple access (section)

=== Advantages of TDMA ===

# '''Enhanced spectrum efficiency''': TDMA maximizes the use of available bandwidth by allowing multiple users to share the same channel without overlapping. Each user is assigned a specific time slot, ensuring that the channel's capacity is fully utilized, thereby increasing overall system efficiency.
# '''Reduction of intersymbol interference''': By assigning non-overlapping time slots to users, TDMA significantly reduces the risk of intersymbol interference. This interference occurs when signals from adjacent symbols overlap, leading to distortion and communication errors. The clear separation of time slots ensures that each symbol is transmitted distinctly, enhancing the reliability and clarity of the signal.
# '''Elimination of guard bands''': Since adjacent channels in TDMA do not interfere with one another, there is no need for guard bands—unused frequency ranges that typically separate channels to prevent interference in other systems. This absence of guard bands allows for more efficient use of the available spectrum, providing additional capacity for more users.<ref>{{Cite journal |last1=Kaur |first1=Amritpreet |last2=Kaur |first2=Guneet |date=2017-03-15 |title=The Enhanced ECC Approach to Secure Code Dissemination in Wireless Sensor Network |url=http://dx.doi.org/10.5120/ijca2017913237 |journal=International Journal of Computer Applications |volume=161 |issue=7 |pages=30–33 |doi=10.5120/ijca2017913237 |issn=0975-8887}}</ref>
# '''Flexible rate allocation''': TDMA supports dynamic allocation of time slots, allowing the system to adapt to varying user demands. Users can be assigned multiple time slots based on their data transmission needs, which can vary due to factors such as call duration or data requirements. This flexibility optimizes resource usage and can improve overall user experience.
# '''Low battery consumption''': Unlike FDMA (frequency-division multiple access), which requires continuous transmission, TDMA operates in a noncontinuous manner. Each transmitter can be turned off when not in use, leading to significant power savings. This is particularly advantageous for mobile devices, as it prolongs battery life and reduces the need for frequent recharging.
# '''Simplified implementation''': The time-based nature of TDMA simplifies the implementation of synchronization mechanisms between users. As users take turns using the channel, the system can more easily manage timing and coordination compared to more complex methods like CDMA (code-division multiple access), where signals overlap.<ref>{{Citation |title=Multiple access techniques: FDMA, TDMA, CDMA; system capacity comparisons |date=2004-12-16 |work=Mobile Wireless Communications |pages=137–160 |url=http://dx.doi.org/10.1017/cbo9780511811333.007 |access-date=2024-10-28 |publisher=Cambridge University Press|doi=10.1017/cbo9780511811333.007 |isbn=978-0-521-84347-8 |url-access=subscription }}</ref>
# '''Scalability''': TDMA systems can be scaled effectively to accommodate a growing number of users. As demand increases, additional time slots can be introduced without the need for significant changes to the existing infrastructure, making it easier to expand the network capacity.
# '''Improved quality of service (QoS)''': With the ability to assign specific time slots and manage user access dynamically, TDMA can enhance the overall quality of service. This can lead to reduced latency and increased throughput, ensuring that users experience reliable and efficient communication.
