Brief Introduction: home wireless LAN topology

The home wireless LAN structure is relatively simple and cheap to build. The following is a simple graphic analysis to help you understand the structure and topology of the home wireless LAN. I hope you can get the desired information.

Simple home wireless LAN

In the most common and cheapest example of a home wireless LAN, 1 shows a device as a firewall, router, switch, and wireless access point. These wireless routers provide a wide range of functions, such as protecting the home network from external intrusion.

Allows sharing a single IP address of an ISPInternet service provider.

Provides wired Ethernet services for four computers, but can also be expanded with another Ethernet switch or hub

Create a wireless access point for multiple wireless computers

These devices come from different vendors, such as LinksysCisco, D-Link, Netgear, SMC, Belkin, and other companies. It takes only 30 dollars to purchase basic modules, and more than 150 dollars to purchase high-end modules. Generally, basic modules provide 2.4 GHz 802.11b/g-operated Wi-Fi, while higher-end modules will provide dual-band Wi-Fi or high-speed MIMO performance. Dual-Band Access Points provide 2.4 GHz 802.11b/g and 5.3 GHz 802.11a performance, while MIMO Access Points can use multiple RF Frequencies in the 2.4 GHz range to improve performance. A dual-band access point is essentially a combination of two access points and can provide two non-interference frequencies at the same time, while an updated MIMO device increases the speed in the 2.4 GHz or higher range. The 2.4 GHz range is often crowded and the manufacturer has avoided dual-band MIMO devices due to cost problems. Dual-band devices do not have the highest performance or range, but allow you to operate in a relatively less crowded 5.3 GHz range, and if the two devices are in different bands, allow them to operate at full speed at the same time.

Home wireless LAN examples are not common. This topology costs more, but provides more flexibility. Routers and wireless devices may not provide all the features that advanced users want. In this configuration, the cost of such access points may exceed the price of a considerable router and AP all-in-one machine, owing to a small number of such products in the market, because most people prefer to combine functions. Some people need higher terminal routers and switches because these devices have features such as bandwidth control, Gigabit Ethernet, and a standard design that allows them to have the needed flexibility.
