Indicates the total number of external antennas that are connected to the device, often WiFi routers or access points. External antennas can be adjusted or rotated to optimize signal coverage in certain areas.

Indicates the number of antennas located inside the device. These antennas cannot usually be physically modified by the user, but can be designed to provide a stable and strong signal.

The RAM of network elements is the operational memory that is used to temporarily store data and instructions needed for the operation of network devices. Higher RAM capacity allows for more efficient processing of network traffic, better performance when multiple users are connected simultaneously, and more stable operation under heavy load. RAM is erased when the device is rebooted.

The flash memory in the network elements stores the operating system, configurations, and firmware even after the device is powered off. Its capacity determines the possibility of updates and extended configurations, which is essential for the management and security of the network infrastructure.

Standards and protocols that the router supports for WiFi communication. This includes various versions of the IEEE 802.11 standard, such as 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac and 802.11ax.

Frequency bands on which the router transmits WiFi signal. Commonly used bands include 2.4 GHz (suitable for greater coverage) and 5 GHz (suitable for higher speed and less interference).

It refers to generations of WiFi technology that have been developed over time to improve the speed, range and reliability of wireless networks. Each generation has its own specific features and benefits, and is defined by its IEEE 802.11 standard.

WiFi routers can be categorized by different types based on frequency bands, speed, range and other technical specifications. The most common types include single-band (frequency of only 2.4 GHz), dual-band (frequency of 2.4 GHz and 5 GHz), tri-band (one 2.4 GHz and two 5 GHz), and quad-band (frequency can be up to 6 GHz) routers.

NAT, or Network Address Translation, is a key technology that allows multiple devices on a local network to share a single public IP address for Internet access. This technology not only makes efficient use of the limited number of available public IP addresses, but also increases network security by hiding the internal IP addresses of devices from the outside world. NAT is essential for managing network traffic and ensuring seamless Internet connectivity in homes and businesses.

This is a set of protocols and techniques designed to secure data transmitted over WiFi wireless networks. Different encryption methods offer different levels of security to protect against unauthorized access and misuse.
