The Institute of Electrical and Electronics Engineers (IEEE) developed the 802.11 standard for Wi-Fi technology, which is used by all wireless routers. The 802.11 standard establishes an over-the-air interface between a wireless client and a base station or between two wireless clients and applies to numerous WLAN standards.
A, B, G, N, and AC are the five Wi-Fi technologies. B, G, and N use the 2.4 GHz frequency; A and AC use the 5 GHz frequency; and N uses both 2.4 and 5 GHz frequencies. Wireless G, N, or AC will be your options for your house or company. Routers with just Wireless B compatibility are no longer produced.
Because they have high broadcast capabilities and enable several devices to experience maximum performance at the same time, wireless AC routers are the ideal solution for small business applications. Depending on the router you choose, you may be able to make use of additional security features as well as server hosting options.
Wireless N routers are an excellent alternative for a wireless network in a home office. They support several PCs and other electronic devices at the same time, so the router will continue to function even when multiple computers, entertainment systems, and other peripheral things are operating at the same time.
Wireless G routers are not a suitable solution for small businesses if you need to connect several devices to the internet or utilise complicated programs or cloud apps.
Before buying a wireless router, be sure that the wireless interfaces on your devices support the technology you intend to use. Wireless AC, for example, is not supported by all devices.
Choosing the correct wireless network and its components may be a perplexing and winding road. WLAN is the way to go for home offices and small enterprises because of its greater range of capabilities, and Wireless AC routers allow you to connect many devices to the network without experiencing network delay.
When it comes to keeping your network’s data secure, router security reigns supreme. When purchasing a new router, you should be familiar with the terms WEP, WPA, and WPA2. All three are WiFi-protected access protocols that encrypt your network and require other devices—including hackers—to have a “key” to obtain access.
How to choose: WEP is considered old and is easy to break by any novice computer hacker. Although WPA is superior to WEP in terms of security, most experts and service providers favor WPA2 security. Fortunately, most new routers support this protocol, so double-check for this while making your purchase. Bottom line: if it lacks WPA2, don’t purchase it!
