Low latency (Laptop)

[GTRacing65]

OpenLTE is not only requiring a huge amount of processing power, but it also requires a very low latency, Low latency of what? memory latency, CPU latency or dpc latency? Because i want to use OpenLTE on my gaming Laptop (i5 11400h) but Laptops usually have a higher latency than PCs

Low-latency kernel. Basically it needs the configurations to be able to process such amount of samples in realtime.

We used the following hardware:

USB 3.0 interface
Modern multicore CPU (Intel Core i5, Core i7 or equivalent with SSE4.1 SSE4.2 and AVX support)
UHD driver installed (for Ettus SDRs)

And make all changes in BIOS to provide the best performance of your equipment:

Remove all power management features inthe BIOS (sleep states, in particular C-states) and CPU frequency scaling(Intel [SpeedStep](https://twiki.eurecom.fr/twiki/bin/edit/OpenAirInterface/SpeedStep?topicparent=OpenAirInterface.OpenAirKernelMainSetup;nowysiwyg=0)). Insome cases, you can also do this with cpufreqtool.

check this using this command: watch grep \"cpu MHz\" /proc/cpuinfo
have a look at [this link ](http://askubuntu.com/questions/523640/how-i-can-disable-cpu-frequency-scaling-and-set-the-system-to-performance)for further information
you may need to add intel_pstate=disable to the Linux boot options, i.e GRUB_CMDLINE_LINUX_DEFAULT="quiet intel_pstate=disable" in /etc/default/grub, then perform update-grub
