Point-to-point wireless communication is a technology that allows two devices or locations to connect and exchange data wirelessly without the need for physical cables.
It is commonly used for various purposes, including connecting remote offices, extending network coverage, or delivering internet access to a specific location. Here’s a simplified explanation of how point-to-point wireless works for someone with limited knowledge of computer networking:
-
Transmitter and Receiver: Imagine you have two buildings or locations, A and B, that need to communicate with each other. In each location, you have a wireless device. One of these devices acts as a transmitter (often referred to as an Access Point or AP), and the other as a receiver (often referred to as a Client or CPE).
-
Wireless Signals: The transmitter device in location A sends out wireless signals, much like a radio station broadcasting a signal. These signals travel through the air to reach the receiver device in location B. The devices are equipped with antennas to send and receive these wireless signals.
-
Line-of-Sight: For point-to-point wireless to work effectively, there should be a clear “line of sight” between the two devices. This means that there should be no major obstructions like tall buildings or mountains blocking the path between them. This ensures that the wireless signals can travel directly from one device to the other.
-
Data Transmission: Once the wireless signals reach the receiver device, they are converted into data, such as internet traffic, files, or other information. This data can then be used by devices connected to the receiver, like computers, smartphones, or other network equipment.
-
Equipment and Configuration: To set up a point-to-point wireless link, you’ll need specialized wireless equipment, like high-gain antennas and wireless radios. These devices need to be configured to work together on the same frequency and settings.
-
Internet Access: In the context of internet access, one location (e.g., location A) might have a wired internet connection, and the point-to-point wireless link is used to transmit that internet connection to location B, providing network access there without the need for separate cables.
