A close shave: 5G to the rescue Dan Rhodes, director of business development at critical
communication equipment provider Filtronic, discusses how, with 5G being deployed around the globe, the sheer amount of data now being downloaded in real-time means that the entire network – including its backhaul – must be capable of delivering without congestion

n 2021, mobile network operator EE launched a TV advert showing actor Tom Ellis being shaved by a robotic arm that was being remote-controlled by a barber based 250 miles away – a stunt only possible with low latency and high-speed data transfer capabilities.
the components of traditional backhaul infrastructure. Its ultra-fast and low-latency connectivity and potential to deliver data speeds above 1 Mbps, as well as the ability to ahead of current mobile infrastructure – if it delivers to its full potential.
increased demand. The construct was simple; most cell sites were equipped with backhaul both fronthaul and midhaul means that there are two new, distinct backhaul concerns: the necessity for extremely dense networks and addressing the low latency needs of increasingly complex applications. Backhaul networks may be less impacted midhaul networks, but backhaul capacity momentum.
feasible choice in many areas. Microwave technology is a fast and economical method for connecting isolated or small groups conventional microwave frequency range of to frequency overload and interference, thus leading to a shift towards millimetre-wave
The E-Band market is projected to grow rapidly worldwide, with a market report E-Band is favoured by operators due to its
spectrum, with over 80% of countries with known telecommunication regulations allowing E-Band deployment. This means that radio links due to their ability to provide high globally.
The E-Band frequency spectrum offers both wireless systems make use of a larger assigned spectrum divided into larger channels, which enables the delivery of multi-gigabit data rates. In comparison, the largest assigned channel and channels, E-Band wireless systems are more robust and reduce modem and cost advantages over traditional wireless systems. This allows for scaling up to gigabit- per-second capacities without the need for additional radio equipment or licensing fees. Although it is susceptible to rain attenuation, the sturdy design of E-Band wireless systems and higher antenna gains make it possible to deliver high capacities with a carrier-grade service availability of 99.99% for distances up

In urban areas, where the distances between mobile base stations are typically short (averaging 1.5km for urban and 2.5km well-suited for ultra-high backhaul capacities. suburban areas account for around 80-90% of the elements in a network that require a backhaul solution.
Transceivers that sit in point-to-point radios, performance and ultra-high capacity across a wide range of frequencies, including E-Band, Each module contains all the transmit and of an E-Band link and provides a simple connection to a high data rate full duplex modem.
distance between stations needs to be larger. This could affect commercial viability – after all, the more power you put in, the higher the costs for installation and operations. Filtronic has been involved in a collaborative project with the UK National Physical
