When calculating the number of APs, you cannot simply divide the total required bandwidth by the

maximum bandwidth of a single AP. You also need to consider other factors such as signal coverage

area, user density, interference level, and application type.

Fingerprint-based positioning technology is a method that uses the signal strength or phase

difference of wireless signals to locate objects. There are two types of fingerprint-based positioning

technology: virtual fingerprint-based positioning and real fingerprint-based positioning. In virtual

fingerprint-based positioning, the positioning engine generates a virtual fingerprint library through

calculations based on the AP deployment and environment information. In real fingerprint-based

positioning, the fingerprint map is obtained through onsite information collection.

A router is not included in a typical RFID system. A typical RFID system consists of three components:

RFID tag, RFID reader, and information processing platform. The RFID tag is attached to the object to

be identified, the RFID reader communicates with the tag and reads its information, and the

information processing platform processes and stores the data collected by the reader.

IPsec uses authentication headers (AHs) and encapsulating security payloads (ESPs) to ensure secure

transmission of service data on the network. AHs provide authentication and integrity verification for

the sender and the receiver, while ESPs provide encryption and optional authentication for the data.
