Ešte nikdy nebola rýchlosť WiFi taká dôležitá. Schválne si skúste spočítať, koľko máte doma bezdrôtovo pripojených zariadení. Určite ich nebude málo. A keď k tomu pridáte napríklad požiadavku na pohodlné streamovanie videa, on-line výučbu alebo home office, tak drvivej väčšine routerov dôjde dych. Preto je potrebné WiFi sieť nielen zrýchliť tak, aby zodpovedala štandardu WiFi 802.11ac. Čo všetko takýto štandard dokáže a čím sa líši od starších WiFi generácií?

This generation, based on the IEEE 802.11ac standard, has brought significant improvements in wireless connectivity. Operating in the 5 GHz band, it offered theoretical speeds of up to 3.5 Gbps. This generation also included advanced features such as MU-MIMO, which allows the router to communicate with multiple devices simultaneously, increasing overall network efficiency.

A device that allows wireless devices to connect to a wired network using Wi-Fi. Access points extend wireless connectivity in buildings or public places.

A technology that allows electrical current to be transmitted along with data over a standard Ethernet cable. This allows devices such as cameras or access points to be powered over a single cable.

In the context of networking, it refers to a device or application that accesses a service provided by another computer, called a server. In wireless networks, this can be a Wi-Fi connected device such as a smartphone or laptop.

Abbreviation for "Multi-User, Multiple Input, Multiple Output". MU-MIMO is a technology in wireless communications that allows a Wi-Fi router to communicate with multiple devices simultaneously, instead of switching between devices. This improves performance and increases capacity and efficiency in dense wireless environments.

A router that transmits on two frequency bands, usually 2.4 GHz and 5 GHz. This provides greater flexibility and performance as the 5 GHz band is usually less congested and offers faster speeds, while the 2.4 GHz band has better range but can be slower due to interference.

This is an outdated method of encrypting WiFi networks that uses a 64-bit key. Although it was commonly used in the past, it is now considered insecure due to its ease of breaking.

Like its 64-bit version, this protocol provides slightly stronger security due to a longer encryption key, but is just as vulnerable and is not recommended for use in modern networks.

WPA-PSK is a variant of WPA that allows you to protect your wireless network using a pre-shared password. This password is shared between all devices that have access to the Wi-Fi network. WPA-PSK provides a basic level of security by encrypting communication between devices and accessing the network with a password. While it's not the strongest form of security, it's still an important step in ensuring that your wireless network is protected from unauthorized access.

WPA2-PSK is a modern and strong way to secure a wireless network using a pre-shared password. This password is used for authentication and data encryption between devices connected to the network. WPA2-PSK offers a higher level of security compared to the previous WPA-PSK standard, which means it is much more difficult for unauthorized people to gain access to your wireless network. This type of security is suitable for home and small business networks, ensuring that your data and connections remain safe from potential threats.

A higher level of WiFi security suitable for enterprise networks. Instead of a single shared password, it requires an individual username and password for each user, often in combination with a certificate or other form of authentication.

WPA2-Enterprise is a highly secure protocol for securing wireless networks that is widely used, especially in corporate environments. This standard provides a significantly higher level of security compared to WPA2-PSK, thanks to complex authentication methods that require individual credentials for each user. Each user must have their own certificate, token or other form of authentication factor, ensuring that only authorized individuals can access the network.

The IPv6 Ready designation indicates that a network device or technology is ready to implement IPv6. Internet Protocol version 6 (IPv6) is the latest version of the Internet Protocol, which was specifically designed to overcome the address space limitations of the older IPv4 protocol. Due to the exponential growth in the number of devices connected to the Internet and the need to ensure their unique addressability, IPv6 offers an almost unlimited number of unique IP addresses.

Cloud access on network devices allows users to manage their devices from anywhere over the internet. This feature provides the flexibility and convenience to configure and monitor network settings without having to be physically present at the device. Cloud access is ideal for managing home networks, as well as for IT administrators managing corporate networks remotely.

QoS, or quality of service, is a feature of network devices that allows network traffic to be prioritized according to the type of service, application, or device. This ensures that important applications such as VoIP (a technology that allows you to make voice calls using a broadband Internet connection instead of traditional or analog phone lines) or online gaming have enough bandwidth and low latency to run smoothly. QoS is key to optimizing network performance, especially in high network load environments.

Airtime Fairness is a feature designed to ensure a fair distribution of airtime among all devices connected to a Wi-Fi network, preventing situations where older or slower devices slow down the network for others. This ensures that all devices have equal access to network resources and improves overall network performance.

A DHCP server is a device or software that manages and distributes IP addresses on a local network. When a new device connects to the network, the DHCP server automatically assigns it an available IP address from a defined range.

A DHCP client is a device that, when connected to the network, asks the DHCP server to assign an IP address. Most modern devices, including computers, smartphones and tablets, have a built-in DHCP client function.
