Following the iOS 14.5 recalibration, some iPhone 11 users have seen an improvement in their battery health percentage
Apple re-calibrated the battery health monitoring system…
Wireless LAN for the internal networks is being implemented by a growing number of organisations. The feature is that it is incredibly comfortable and the need for a physical LAN cable is removed. Constructing a wireless LAN, though has various problems than a wired LAN. Let’s describe the network construction points on the basis of a general example of wireless LAN setup.

A personal computer is linked to the network by a wireless LAN access point on the wireless LAN (AP). The number of APs that can be linked, unlike switches that have a set number of ports that can be connected, is not fixed.
Therefore, determining how many terminals (personal computers, smartphones, etc can be accommodated with one AP when creating a wireless LAN network. If the number of terminals to be accommodated is determined, it is possible to determine the number of APs to be added from the number of terminals to be used.
The greater the amount of accommodations, the lower the speed of contact (throughput). At terminals far from the AP, the area that one AP must cover becomes larger, and the state of the radio wave deteriorates. The high-speed networking mode cannot be used in some situations.
The estimated number of units that can be accommodated in the AP was announced by the AP provider. Such information will be helpful when deciding the number of cars to be accommodated.
If the number of terminals that use a wireless LAN is limited and can be protected by one AP, installing just one AP is necessary. However, add a wireless LAN controller that handles multiple APs together while using multiple APs on the same floor. The control dilemma can be rescued and the radio wave environment streamlined.
Also, if the number of APs is large, the power supply for each AP may be difficult to secure. Using a switch that supports PoE (Power over Ethernet) in that case, and will provide power from the LAN cable.
