In the last few years, there has been an increasing demand for backhaul microwave networks, due to the higher usage of mobile data in developed countries and the increasing availability of new technologies in lower band frequencies. The term “backhaul” is a combination of two words that are usually used interchangeably: Backhaul is the process of distributing voice and data communications over long distances, and microwave is the application of microwave radiation for telecommunications. This Study will concentrate primarily on the need for backhaul microwave links for support of the faster growth of wireless broadband access networks and cellular networks at lower frequencies up to 29.5 GHz. Some decades ago, the average consumer did not require a high-speed internet connection because the typical communication scenario involved voice and data communication via telephone landlines, mobile phones, fax machines and email. With the introduction of new technologies such as GSM, EDGE and VoIP, consumer demands for faster data transmission through these mediums prompted service providers to introduce backhaul copper links for improved access to the increasingly popular mobile wireless network.
How to know about backhaul Microwave
The primary purpose of a backhaul microwave system is to enable voice and data communications to be transmitted at a much faster speed through the use of unlicensed, carrier-grade microwave transmitters operating in the lower to mid-bands frequency bands. These microwaves have the capability to penetrate interior building walls and other barriers, while the backhaul microwave system can travel freely outside the main building. The primary components for these systems are the microwave transmitter, which is placed inside the home or other structure, and the backhaul antenna, which connects the transmitter to the backhaul microwave link. A backhaul antenna is typically made out of a coil that has a variable length and a directional coupler, which enables it to receive and transmit waves in the right direction, thus enabling efficient backhaul operation. The backhaul microwave systems generally operate in single or multiple bands.
For a home installation, several factors need to be considered before selecting the most appropriate type of microwave device, such as the size of the area to be covered, the number of users, and the amount of power consumption required. Most households would be able to fit one or more microwave devices, depending on their requirements and the available space. While a small rural home or a small workplace might not require more than a single device, the amount of usage can vary greatly, depending on how much wireless connectivity the area enjoys. It would be prudent to ensure that the required bandwidth and the maximum transfer rate are met when purchasing a backhaul microwave system.
