As we can see the delay dropped significantly when using PCF. However‚ using fragmentation resulted in different effect in DCF and PCF. In DCF using fragmentation increased the delay as the collisions increased while fragmentation decreased the delay when used with PCF. Using fragmentation in DCF did not affect the load much and it remains nearly the same. However‚ using PCF resulted in load drop and when we used fragmentation with PCF the load decreased even more. As expected‚ the throughput

4G Wireless Networks: Data and Bandwidth Improvements How much faster is 4G compared against 3G? The speed of 3G networks depends on how they are implemented. By 2010 Verizon (a CDMA network) had reached the limits of its 3G network speed in the United States. 4G networks allowed Verizon the ability to offer transmission speeds up to four times faster than its current 3G network. AT&T’s 3G network‚ however‚ is based on GSM. The GSM design left AT&T room to upgrade its current 3G speeds
