Great bro Please go deeply in troubleshooting and I already subscribed, keep going

Everything is great. Kindly use a mic since the sounds is very low and bearly hearable. Thanks

Hi, Can you use a microphone in your videos, please? The audio is very low!

[@muhudiinyusuf6900]

thanks sir , for sharing knowledge , it is use full lessons for Optimization and network planning . I got always the video voice is too low same times not easy to hear. please adjust the voice to make high

Any recommended settings of parameters vendor wise ?? Pls guide us vendor wise like for ericsson nokia huawei zte We need your expertise sir

[@WinInk]

I try to keep it vendor free and focus on the concepts. If you have clear understanding, parameters are very easy to manage :)

[@travellingmess8670]

@@WinInk much appreciated for that But it's a request from our end , please provide some insight on vender parameters also .

im not an engineer but im to curious about 4g lte...i got 76mbps on band 40 20mhz at night but got 1mbps on same band an pci at daytime,my question is how speed is devided and is there any backhual restrictions on cell site during daytime?

[@WinInk]

Hi Swapnil. The difference in data rate/speed is because of the network congestion. In the night time, there are fewer people using the cell site resources and therefore you can be allocated more resources and hence more speed/data rate. In the day time, the site which serves your area maybe having congestion and therefore less number of resources allocated to you and lower data rate. There are always backhaul data limits but they are in the range of Gigabits and terabits per second so should not be impacting user level data rate.

[@GreylionX]

@@WinInk thanks for replying..and one more question...is 20mhz(band40) bandwidth is devided in all three sectors or each sector have 20mhz bandwidth?

[@WinInk]

20Mhz is for each sector for that particular band. There may be other bands on each sector with their respective bandwidth. All of this bandwidth per sector is then divided among the users.

Hello Can you Please tell about TTI Utilization measure in LTE? . Usually PRB utilization is taken as Capacity measurement in LTE. But Currently where I am working in network they are considering TTI utilization as capacity measure. As per my understanding "TTI utilization" is giving a number of how many active users are present in a TTI or a specific time interval. Is this understanding is correct? If no plz share your POV. Thanks

[@WinInk]

TTI utilization may not correctly reflect if all PRB are being allocated within that TTI which means it will not reflect how much of the full capacity is being used

[@khizarkhan1341]

Can u tell how Low Sinr reporting cause High RB utilization ? Low SINR leads to low modulation Scheme resulting in low coding rate , then how High RB can be used ?

[@WinInk]

In case of SPS or any case of persistent scheduling, the scheduler algos of MCS are bypassed and specific RB resources are allocated irrespective of the radio conditions, This is the case in VoLTE. I hope it made it clear. Thanks

[@khizarkhan1341]

WinInk Thanks for the reply .. But u mean in VOIP SPS is not used ? Please also guide that BLER target are also maintained by EnodeB through specific algos to maintain BLER target. is this can also be a factor for taking high utilization . E.g in some cases I have seen high Mcs causing high BLER which seems confusing.?

[@WinInk]

I mean to say that SPS is indeed used. I will make a separate video on BLER

[@khizarkhan1341]

WinInk ok sure Thanks for the replies .👍

[@ZahoorAhmad.122]

please can explain whats can isue if in field DT plot have Good Sinr But LTE throughput in KBPS in overall cells drive

[@WinInk]

Hi Zahoor. if possible, can you rephrase the question. Are you referring to good SINR and low throughput?

[@ZahoorAhmad.122]

@@WinInk G Sir Exact .....In Field Drive This Issue Face me Frequently..And Thanx For such a nice lecture salute sir..

[@nicholasjumba6032]

Ok. This may happen if there is congestion or a capacity constraint. Throughput also has a direct relationship with the channel bandwidth. So if the bandwidth is small, throughput is likely to be low.
