What is backhaul and fronthaul?

Backhaul links the mobile network to the wired network, while fronthaul describes the network architecture that connects the remote cell sites to the BBU. More specifically, wireless backhaul is the wireless communication system that gets data from a remote location to a major network.

What is fronthaul Midhaul and backhaul in 5G?

The 5G fronthaul transport network interconnects Active Antenna Unit (AAU) to DU. The 5G midhaul interconnects the CU to the DU. 5G backhaul is essentially similar as in 4G but carrying much more traffic due to higher performance and higher bandwidth 5G New Radios.

What is backhaul transmission?

The term backhaul is often used in telecommunications and refers to transmitting a signal from a remote site or network to another site, usually a central one. Backhaul usually implies a high-capacity line, meaning high-speed lines capable of transmitting high bandwidth at very fast speeds.

What is fronthaul WIFI?

Fronthaul is defined as the fiber-based connection in RAN infrastructure between the Baseband Unit (BBU) and Remote Radio Head (RRH). Fronthaul originated with LTE networks when operators first moved their radios closer to the antennas.

What is 5G backhauling?

The mobile backhaul network connects radio access network air interfaces at the cell sites to the inner core network which ensures the network connectivity of the end user (e.g., mobile phone user) with the mobile networks (shown in Figure 2).

What does backhaul mean?

(Entry 1 of 2) 1 : the return movement of a transportation vehicle from the direction of its principal haul especially transporting a shipment back over part or all of the route.

What is 5G Midhaul?

Simply put, fronthaul connectivity comes into play when the RU is located separately from the DU. Midhaul connectivity describes the communication link between physically separated DUs and CUs. Fronthaul is becoming increasingly essential with the growth of 5G networks.

What is 5G Oran?

The arrival of Open Radio Access Network (ORAN) technology being deployed by mobile operators ultimately will lead to innovation as the equipment supplier ecosystem expands. Nonetheless, traditional equipment suppliers continue to build out consumer-facing 5G networks.

Why is backhaul needed?

Specifically, deploying more sites with higher capacity and reduced latency while supporting multiple services requires backhaul that allows operators to eliminate dependency on fiber availability and feasibility when planning, locating and acquiring new cell sites.

What is wireless backhaul?

Wireless backhaul is a means for connecting broadband sites to the core network in a wireless manner. In fact, according to the Ericsson Microwave Report, about 38% of all global telecom sites will be connected to the rest of the network via wireless backhaul, by 2025.

What is Fronthaul multiplexer?

The 5G FHM is equipment having a multiplexing function for splitting and combining a maximum of 12 radio signals on the fronthaul. It was developed in conjunction with the 5G service rollout the same as RRU (Photo 4).

What is the difference between backhaul and fronthaul?

Split RAN architecture has reshaped the traditional definitions of fronthaul and backhaul. In its earliest incarnation, backhaul was simply described as the connection between the wireless network and wired network through either cable or optical fiber.

Where does mobile backhaul and mobile fronthaul come from?

All that mobile traffic eventually has to be transported back over traditional wired (and mainly fiber optic) networks. That’s where mobile backhaul comes into play. But there’s a new mobile architecture to talk about as well: mobile fronthaul .

What’s the difference between wireless backhaul and wireless fronthaul?

Backhaul links the mobile network to the wired network, while fronthaul describes the network architecture that connects the remote cell sites to the BBU. More specifically, wireless backhaul is the wireless communication system that gets data from a remote location to a major network.

How does fronthaul relate to the baseband unit?

Fronthaul is defined as the fiber-based connection in RAN infrastructure between the Baseband Unit (BBU) and Remote Radio Head (RRH). Fronthaul originated with LTE networks when operators first moved their radios closer to the antennas. This new link was established to supplement to the backhaul connection between the BBU and central network core.
