    Hi Raquel. I really enjoyed this video. I'm putting together a presentation for a class project on how a cell phone call works. It's going to go into a little more depth of the equipment between the cell towers. I would really like to use your video in my presentation if that's ok with you? Thank you.

    Did you do this for a school project or just on your own? If the former, what grade did you get? If the latter, good job! But what motivated you to do something so professional?

    Hello and thank you for this video!  I don't know if you are planning to make this a part of a series, but here are some add'l questions that i have: 

    • How do cells divide up the city and allow frequency reuse?  
    • What is a “control channel”?  How does it work? 
    • So is each cell assigned to a carrier and each SID is assigned to a cell? How many users can use a cell at a time? How many users can use a frequency at a time? What happens when users from different carriers need service throughout the city? What happens in congested areas of high cell phone use?
    • Once your phone and the tower switch on the assigned frequencies, your call is connected.  Are two frequencies (one for one speaker and the other for the other) assigned in both the city where a call originates and in the city where the call is received? What is the full path of data from caller to receiver? How do the following terms fit into this?
    • Device: phone/pc/tablet
    • Transmitter
    • Receiver
    • CO
    • Backaul
    • Cabinet
    • Cell

    Thank you everyone for your comments.

    I am aware that there are errors in this presentation because of the very simplified concepts. But I hope I can improve so I can help you guys out. Thanks again.

    P.S. Apologies for my 12 year old sounding voice. I lacked a voice actor when this animation was due during my undergrad. :)
