Multiplexing is the process of combining multiple signals and transmitting them over a common channel and it is implemented on telecommunication using Multiple Access as a Application.\r
\r
Here, Multiple Access is explained with the example of Wi-Fi Hotspot sharing its internet connection among multiple users by providing them a frequency block over which they can transmit and receive data. The greater the size of this block, greater is the throughput.\r
\r
There are several way by which we can use Multiple Access Technique such as TDMA, FDMA, CDMA, W-CDMA, SDMA, OFDMA, SCMA.\r
\r
We have also mentioned, How TDMA and FDMA, CDMA, W-CDMA works and implemented in Earlier Generation system which is AMPS, GSM, GPRS, EDGE, UMTS, HSPA+.\r
\r
To overcome issues faced in earlier generation such as,\r
- Low Throughput\r
- Low Spectral efficiency\r
- Resource wastage and many more,\r
We have introduce next Generation Multiple Access technique which is already deployed in WIFI and in WIMAX, but due to lack of backward compatibility and support for Mobile communication in WiMAX, Operator started to working OFDM to include in LTE.\r
