This article provides an in-depth analysis of the key parameters and functions of routers to help readers better understand and choose a router that suits their needs.Key Parameters of RoutersWireless StandardThe wireless standard is an important parameter that measures the wireless transmission performance of a router. Currently, common wireless standards include 802.11n, 802.11ac, and 802.11ax, among others. Routers with different standards have different transmission rates, transmission distances, and anti-interference capabilities, so selection should be based on actual needs.Frequency BandsRouters mainly operate in two frequency bands: 2.4GHz and 5GHz. The 5GHz band has a faster transmission speed but a relatively smaller signal coverage, while the 2.4GHz band has better signal penetration and coverage. Select a router with a suitable frequency band based on the actual layout of the home or business and equipment needs.Processor and MemoryThe processor and memory play a decisive role in the processing power and running speed of the router. A high-performance router needs a powerful processor and large memory capacity to cope with complex network environments and data transmission requirements.Port Number and TypeThe number and type of ports on the router are also key parameters to consider during selection. Choose a router with the right number and type of ports (such as LAN ports, WAN ports, etc.) based on the actual needs of the home or business.Functions of RoutersNetwork Connection FunctionAs the core device for network connection, routers can achieve data transmission and sharing between different devices. By connecting broadband lines, routers can transmit network signals to every corner of a home or business.Wireless Signal Transmission FunctionRouters have wireless signal transmission functions, enabling wireless device access and networking. Through wireless signal transmission, users can easily meet the networking needs of various electronic devices.Firewall FunctionRouters have
