    hi
    1- you can specify the users speed in sim_main_launcher_demo_basic ==> LTE_config.UE_speed = 5/3.6;
    2- you can find it in simulation_config.

    can anybody help me for this?
    how can I place the user in static position (Less or No Mobility)
    where and what should I change

    Hello Ramdharma,

    the user can be kept in static position by setting the “keep_UEs_still” as true. i.e.

    LTE_config.keep_UEs_still = true;

    Trust this helps

    Dear Ramdharma,

    the user speed is only used for the channel model. If you want to physically move the user over the map, you have to specify a walking model.

    Martin.

    Thanks a lot for your reply. I want to simulate (Monitor) only the VoIP user alone. One more doubt that I have. What is FullBuffer in traffic model. I thought it is a combination of all traffics(gaming, voip, http, ftp, video). Is it correct? or Am I wrong with this?

    Mr.Martin, I want to compare the VoIP traffic in High Mobility and No Mobility scenarios. Please tell me the ways (code) to proceed and how?

    Thank you Manikantan sir, Am using “LTE_System_Level_1.6_r885”, will your code work for this version?.
    How to identify the particular UE belongs to this particular traffic model. What coding should I include?

    Hi Ramdharma,

    you can employ the voip traffic model from +traffic_models. Please see +simulation_config.hex_grid_tilted_traffic.m how to configure it.
    High mobility can be modeled by specifying the user speed and a walking model from +walking_models.

    Best regards,
    Martin.
