    Thanks for watching this Video, Please Like and Share.
    UE tune to each and every channel that it support and measure RSSI.
    RSSI is simply a measurement of whatever energy/power it can measure. This measurement does not require any channel coding process. So at this step, UE does not need to know anything about the network. At this step, UE does not try to decode PCPICH in WCDMA or Sync/Reference Signal in LTE to detect Physical Cell ID. It just measure the power of each channel. As UE measure RSSI for each channel, it create a list of each channel numbers with the measured RSSI.
    Then UE go through the list from
    step i and figure out all the channels which shows RSSI value greater than the threshold
    Then the question would be "Any frequency with Passing RSSI value can be the one that UE can camp on ?". The answer is "Not Necessarily".
    For find the more proper candidate to camp on, UE performs following steps.
    UE decode PCPICH and measure the power and detect physical cell ID from the each candidate from step ii
    Some candidate give successful result but some would not. UE make the list of all the successful tries
    From the list with successful result from step iii, UE decode MIBs for each and every candidate. With this procedure, now UE can make a list of frequency, Physical Cell ID PSC in case of WCDMA and PLMN.
    Based on USIM information and the candidate table from the step iv, can figure out which cell is the real candidate cell to camp on and try decoding System Information and proceed to registration process.
    I am available here for support you and always uploading video for you.
    I am working in wireless technology where what i learn same knowledge, technology and technical things
    shared with you in video format.
    Apart from Technology my involvement in creating on-line money and also learn related to some technical and social things which is my
    Learning Habit, I do not want to keep these things confined to myself.
    I would be glad if my video would be a helpful for you.

    Good explanation. here the master later is the layer which controls PHY layer and that is RRC. The protocol stack evokes at once but wait for instruction according to the process(specifications).

    मैं मोबाइल मैकेनिक ।मेरे लिए मोबाइल नेटवर्क कैसे काम करता है यह जानना बड़ा जरूरी होता है क्योंकि अगर हम प्रोसेस को जानेंगे तभी मोबाइल रिपेयर कर पाएंगे क्या ऊपर ऊपर जानकारी के लिए एक वीडियो बना सकते है जिससे हम फाल्ट की एनालसिस कर सकें

    Why carrier spacing 12khz??

    • @AnandTechnoSolutions

      15KHz

    • @prashumrn
      @prashumrn 5 років тому

      Anand Technical Support that was typo error.
      Why the spacing is only 15khz ???

    • @prashumrn
      @prashumrn 5 років тому

      It was typo error.
      Why this is 15 khz???

    • @AnandTechnoSolutions

      @@prashumrn For minimize performance degradation from phase noise, the subcarrier spacing should be greater than 10 kHz. to support UE up to a speed of 250 km/h, the subcarrier spacing should be around 9-17 kHz. As a result, a subcarrier spacing of 15 kHz was chosen for LTE.
