Access points serve as the connection between wireless clients, such as laptops or mobile devices, and the wired network. Antennas are responsible for transmitting and receiving radio waves, ensuring reliable connectivity throughout the network.
The most common wireless network topology is the star topology, where each wireless client connects to the access point in a centralized manner. This topology offers ease of management and scalability, making it an ideal choice for most small and medium-sized businesses.
Wireless Infrastructure
The wireless infrastructure comprises the hardware and software components of a wireless network. A typical wireless infrastructure includes access points, antennas, switches, routers, and servers. The hardware components are responsible for transmitting, receiving, and processing data, while the software components govern network security, connectivity, and management.
Access points are the primary hardware component of a wireless infrastructure. They serve as the connection point for wireless clients, enabling them to communicate with the wired network. Access points are available in various configurations, from standalone devices to multi-radio access points that can support multiple wireless networks simultaneously.
Antennas are responsible for transmitting and receiving radio waves, ensuring that data is reliably transmitted between devices. They are available in different frequencies, ranging from 2.4 GHz to 5 GHz, and various types, including directional and omnidirectional antennas. Each antenna type has its unique advantages and disadvantages, making it crucial to understand the specific use case.
Did you know? The term ‘topology’ refers to the physical layout of the network, while ‘infrastructure’ refers to the hardware and software components that make up the network.
