What is a wireless backhaul system?
Wireless backhaul is the use of wireless communication systems to transport data between the internet and subnetworks. One example of wireless backhaul is a smartphone that connects to the internet by receiving data from a cell tower or another kind of base station.
What is non line of sight communication?
Non-Line-of-Sight (NLOS) is a term often used in radio communications to describe a radio channel or link where there is no visual line of sight (LOS) between the transmitting antenna and the receiving antenna.
What is backhaul system?
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 5g wireless backhaul?
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 would be an example of a backhaul connection?
A local WAN or WLAN connection is an example of a backhaul. A typical telephone company provides internet service for users through backhaul. For instance, cell phones that are able to communicate with a cell tower serve as local subnetworks for those who use them.
How do I check my wireless line-of-sight?
Checking Line of Sight#
- Use the ruler tool to measure the distance between the two points.
- The ruler tool will show you the distance and the azimuth between the two points.
- Click ‘Save’ on the ruler tool.
- Go to the ‘Altitude’ tab on the line properties.
- Change ‘Clamped to Ground’ to ‘Relative to Ground’
Does RF require line-of-sight?
Attaining RF Line-of-Sight (LOS) between the sending and receiving antennas is essential in achieving long range in wireless communication systems. RF LOS requires not only visual LOS, but also a football-shaped path free of obstacles for data to optimally travel from one point to another.
What is fronthaul and backhaul in 5G?
A primary difference between fronthaul and backhaul is the part of the network the technology is deployed on. Backhaul links the mobile network to the wired network, while fronthaul describes the network architecture that connects the remote cell sites to the BBU.
What is backhaul LTE?
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.
Why do I need line of sight for my wireless backhaul?
In a NLOS wireless link application point to point wireless Ethernet bridge radios that use OFDM or MIMO take advantage of multipath for their connectivity. Because a licensed microwave link is not to inject any interference on other licensed microwave backhaul operators in the area they must have LOS (line of sight) and not cause heavy multipath.
What kind of wireless backhaul can be used on outdoor bridges?
Outdoor wireless bridges that can take advantage of these wireless backhaul technologies are the unlicensed wireless systems. Unlicensed wireless backhaul using these technologies can provide up to 300Mbps aggregate throughput (depending again on the characteristics of the microwave link path).
Do you need line of sight for microwave backhaul?
Because a licensed microwave link is not to inject any interference on other licensed microwave backhaul operators in the area they must have LOS (line of sight) and not cause heavy multipath.
How does a point to point wireless backhaul work?
In a NLOS microwave link the RF signals will get to a destination by: diffraction around an object, reflection off objects, or by penetration through the obstruction. For an outdoor wireless bridge, being used for high bandwidth, point to point backhaul to work in a NLOS application there are several requirements that need to be met.
