Backhaul provides internet users with access to the internet by expanding the network’s coverage area. In this article, we look at the definition and features of backhaul.
What is a Backhaul in networking?
Backhaul in networking connects a cell site to the core network; this process is called mobile backhaul. Furthermore, it helps you connect to the global Internet, and you can pay for commercial access.
What is Backhaul in wireless communication?
Backhaul in wireless communication refers to the transmission of data between the internet and a subnetwork. It can assist a company or mobile network in doing away with physical cabling. They do this by using microwaves or radio waves to convey signals between wireless access points.
How Does Backhaul Work?
#1. Data transmission:
Backhaul allows for the transmission of audio, video, and data from a wireless carrier’s mobile base station or cell tower to the carrier’s mobile switching center (MSC).
#2. Transmission:
The three primary transport means used for backhaul multimedia traffic are:
- Optical fiber,
- Microwave (through the wireless spectrum), and
- Traditional copper connections.
#3. Fiber connections:
In remote areas like islands, where fiber optics are expensive, service is frequently expanded using microwave links. However, in developed countries like the United States, they use fiber-optic networks to connect cell towers.
#4. Phone signals:
When a user makes a phone call, for example, the following procedures happen:
- Through the radio frequency band, mobile phones transmit their signals to an antenna mounted atop a cell tower. This communication is wireless.
- The base station converts radio waves on the spectrum into backhaul.
- For instance, the signal is delivered via fiber to market-level aggregation stations.
- Before being sent to the cellular core network architecture, traffic is then consolidated.
- The network then transforms the call signals from the backhaul into a format that can be understood by the spectrum at a different base station as the final stage.
- The device of a new user gets the connection through a nearby cell tower.
Why is backhaul used?
#1. It enables wider public connectivity in a metropolitan area network (MAN).
Many cities make use of Metropolitan area networks, also called MANs. Furthermore, you can connect to this network even if your house or workplace does not have cabling installed. Additionally, they can rely on this network since the wireless feature enables dependable connectivity in places like stores, parks, and even city streets.
#2. It drives secure operations
Organizations can raise the security standards of their operations by using it. By utilizing the wireless feature, which also permits last-mile aggregation, you ensure secured operations during business. Furthermore, these wireless networks can transfer hundreds of data channels, enabling efficient and unrestricted data, video, and voice transmission.
#3. It supports 5G.
The most significant and expansion-focused use of the wireless feature is 5G. For wireless carriers and their customers using 5G networks, the architecture of 5G backhaul offers several opportunities to expand and enhance internet access.
#4. It solves mobile networking challenges
Networks are undergoing a variety of developments, and backhauls offer a chance to address and resolve many of these problems. Furthermore, the deployment of more cellular sites with improved capacity reduces latency, and the capacity to manage diverse services, in particular, depends on it.
#5. It strengthens private networks
To provide broadband access to corporate campuses, other types of institutional settings, and the industrial Internet of Things (IoT), private networks are swiftly taking over. Enterprise applications, multimedia traffic, and even basic interactions all place a heavy demand on available bandwidth. Therefore, it is the key element of the architecture of private networks and is occasionally referred to as a transmission network.
What are the different types of Backhaul networks?
#1. Wired backhaul
In this case, data is sent through wired lines. The bulk of activities are carried out over wired connections, often over fiber-optic networks; however, in some circumstances, it may also be done over more traditional copper-based T-1 lines.
Furthermore, this is explained in more detail if you take a closer look at some of its subcategories.
- Copper lines: Copper-based backhaul is based on the T1/E1 protocol, which allows for data transfer rates of 1.5 Mbps to 2 Mbps.
- Dark fiber backhaul: The raw material for wireless network carriers is dark fiber backhaul. Note that this power allows them to create their services, run their networks, and achieve performance levels that are tailored to their own needs.
- Ethernet backhaul: Ethernet backhaul is a fiber-based transport service that enables wireless carriers to expand the coverage of their networks. Generally, most enterprises primarily employ this kind of backhaul.
#2. Wireless backhaul
Microwave connections, which are made possible by the wireless spectrum, are used to transmit music, video, and data traffic. This is also known as a wireless backhaul or fixed wireless. A particular kind of antenna, known as a microwave dish, is used for point-to-point data transmissions.
Furthermore, the licensed wireless spectrum, particularly millimeter wave (mmWave) bands, is used to transmit the audio, video, and data components.
#3. Satellite backhauls
MNOs occasionally use satellite backup as a temporary or emergency measure in locations like remote rural areas. Backhaul is used in a catastrophe area or a microwave connection area while awaiting license clearance.
In situations like these and generally, backhaul is used in both mature and emerging markets to serve a complementary role.
#4. Wi-Fi backhaul
Wi-Fi backhaul allows for the assistance of small cells at the edge of a wireless carrier’s network. To enable wireless connection services both inside and outside of the customer’s home, a tiny cell, also known as a femtocell, is installed in the customer’s residence.
At the end of the day, Wi-Fi backhaul helps bring connections to areas where traditional dark fiber or microwave connectivity is either not available or too expensive.
What is Backhaul Logistics?
In logistics, backhaul refers to the journey of a transport vehicle back from its final destination to its starting place.
What is Backhaul fiber?
Backhaul fiber is used to connect the core networks with the smaller subnetworks toward the edge. Its function is to expand the network’s coverage area.
What is backhaul Internet?
Backhaul Internet is the connection that allows you to transmit data between local networks and the broader internet. In simple terms, it is the transfer of data from your home or workplace to internet service providers.
What is Access?
Access to networks allows your smartphones, tablets, or computers to connect to the network and access its services. It serves as the connection between the network infrastructure and user equipment.
Its parts include:
- Base stations,
- Antennas,
- Routers,
switches, and - Cables.
What is the difference between access and backhaul?
The main differences between wired access backhaul and wireless access backhaul are as follows:
| Wired access backhaul | Wireless access backhaul | |
| Cost: | It is very expensive due to the cost of the materials needed to build it. | It is less expensive |
| Security: | They offer more security. | They offer less security |
| Reliability: | They are more reliable | They are less reliable. |
| Latency: | It has a lower latency | It has a higher latency |
| Bandwidth and Speed: | They offer a faster speed | They offer less speed |
| Physical vs. Wireless Connection: | Wired access backhaul uses physical cables | Wireless access Backhaul uses a wireless connection. |
What is Backhaul management?
Backhaul management is the effective maintenance of backhaul network infrastructure.
Furthermore, it allows for
- Smooth data transmission,
- Optimal network performance, and
- A positive user experience.
