What is mobile backhaul network?

Mobile backhaul refers to the transport network that connects the core network and the RAN (Radio Access Network) of the mobile network. Recently, the introduction of small cells has given rise to the concept of fronthaul, which is a transport network that connects the macrocell to the small cells.

What is mmWave backhaul?

Microwave and Millimeter wave (mmWave) backhaul links are versatile and can support significant data rates. The E-band can handle between 15X and 20X more traffic than the typical mid-microwave band (14 Gigahertz (GHz) to 25 GHz) backhaul links.

What frequency is microwave backhaul?

Historically, microwave backhaul has used much higher frequencies (from about 6GHz to 86GHz) than mobile radio access, which today uses spectrum ranging from about 400MHz to 4GHz. For 5G radio access, research is currently underway on the use of much higher frequencies (above 24GHz).

What is microwave backhaul?

Microwave backhaul refers to the transportation of traffic (voice, video and data) between distributed sites and a more centralised point of presence via a radio link.

What is 5G backhaul network?

Based on the deployment area and user traffic, the 5G backhaul network will be a combination of wired (e.g., fiber) and wireless backhaul (millimeter wave, and free space optics). Thus, understanding the basic backhaul network requirements is the key to choose the right technology and type of network.

What is integrated access and backhaul?

Integrated access backhauling (IAB), where part of the wireless spectrum is used for the backhaul connection of base stations instead of fiber, is an attractive solution that could make dense deployments economically viable. With this main objective, 3GPP is in the process of standardizing multi-hop IAB networks.

Is 11 GHz unlicensed?

In a legacy FDD (Frequency Division Duplexing) 11 GHz radio two channels are licensed, a transmit and receive from either site. These channels are of equal size, up to 80 MHz wide and 490 MHz apart. The radios simultaneously transmit and receive on both channels.

What is a powerline backhaul network?

Powerline. The third and final type of mesh networking compliments the Wi-Fi access to devices, by usingexisting power cabling in your home to send and receive the backhaul and inter-node data. Powerline adds a new route, freeing the Wi-Fi to carry more traffic.

Microwave backhaul refers to the transportation of traffic (voice, video and data) between distributed sites and a more centralised point of presence via a radio link.

What is mobile backhaul and how does it work?

What is Mobile Backhaul? Mobile backhaul refers to the transport network that connects the core network and the RAN (Radio Access Network) of the mobile network. Recently, the introduction of small cells has given rise to the concept of fronthaul, which is a transport network that connects the macrocell to the small cells.

Is DSL still a viable option for mobile backhaul?

For all that, DSL is still an option for mobile backhaul for indoor small cells, in-building HetNets, and public venue small cell networks. This technology is the mainstay wired backhaul in MNO networks and second overall only to microwave backhaul.

Which wireless bands are suitable for HetNet backhaul?

Microwave and millimeter bands (V-band (60 GHz) and E-band (70/80 GHz)) are very suitable for HetNet backhaul because it allows for outdoor cell site and access network aggregation of traffic from several base stations, which can then be handed off to the mobile switching centers and finally the core network.
