Packet Switching 1. GPRS involves overlaying a packet based air interface on the existing circuit switched GSM network. 2. In GPRS, the information is split into separate but related "packets" before being transmitted and reassembled at the receiving end Spectrum Efficiency 1. Packet switching means that GPRS radio resources are used only when users are actually sending or receiving data. Rather than dedicating a radio channel to a mobile data user for a fixed period of time, the available radio resource can be concurrently shared between several users. 2. This efficient use of scarce radio resources means that large numbers of GPRS users can potentially share the bandwidth and be served from a single cell..

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
