What is ieee802 11h?
IEEE 802.11h-2003, or just 802.11h, refers to the amendment added to the IEEE 802.11 standard for Spectrum and Transmit Power Management Extensions. It solves problems like interference with satellites and radar using the same 5 GHz frequency band.
What is regulatory mode in WIFI?
[edit] Regulatory Mode It was originally designed to address European regulations but is now applicable in many other countries. The standard provides Dynamic Frequency Selection (DFS) and transmit Power Control (TPC) to the IEEE 802.11a MAC.
What are the advantages and disadvantages of 2.4 GHz vs 5GHz WiFi?
The advantage of a 2.4 GHz is that it has a farther range and it can penetrate solid objects better. However the disadvantage that it has, is that it’s more vulnerable to interference. That’s because so many other devices use the same band and it’s also slower than the 5 GHz.
How many cores do you need?
When buying a new computer, whether a desktop PC or laptop, it’s important to know the number of cores in the processor. Most users are well served with 2 or 4 cores, but video editors, engineers, data analysts, and others in similar fields will want at least 6 cores.
Is more cores better for streaming?
But simply put, yes more cores/threads helps tremendously with streaming. The loss of performance from a CPU with more cores/threads is pretty minimal. Higher clock speed per core = better game performance for CPU intensive games.
Is it better to have more cores or more threads?
A CPU that offers multiple cores or hyper-threading may perform significantly better than a single-core CPU of the same speed that doesn’t feature hyper-threading. And PCs with multiple CPUs can have an even bigger advantage.
