# Time Division Duplexing Tx and Rx are transmitted in different time slots. Two simplex time slots on the same frequency for communication. ![](attachments/Time%20Division%20Duplexing-attachment.png#invert) ## Benefits - Reuse the filters, mixers, frequency sources and synthesizers. - Eliminates complexity and costs of isolating the transmit antenna and receive antenna. - Can use entire bandwidth and all transmit power. - Makes it easy to dynamically reconfiguring - adjust the proportion of uplink vs. downlink (e.g. uploading to instagram/tiktok etc.) just by changing switching time ## Drawbacks - But there is a time delay (latency) introduced. - Have to wait for uplink if you have an urgent message [^1] # References [^1]:
