Powering 5G in building networks Safely
Stuart McKay, business development manager at Panduit, says as an intelligent building infrastructure solutions manufacturer and supplier, the company works with industry leaders, standards bodies, installers and customers to develop and introduce innovative solutions to organisations problems
What are the cabling options telecom carriers can choose from when it comes to 5G Networks?
T
here are two prime factors to delivering 5G to buildings. One is that 5G is power hungry, and the other is that a building’s construction can reduce signal penetration into and around the interior and requires DAS to support the network. Therefore, building operators need to change their thinking on structured cabling to support the latest 5G technology.
Increasing in-building deployment of 5G requires the capability to support many internal wireless devices and connected equipment in a seamless and simple to install and maintain structured architecture. To maximise data reach, most, if not all, 5G radios today take single mode fibre which maximises bandwidth and data reach. Therefore, building operators today are running single mode fibre in their buildings.
The challenge is how to power those radios.
Traditionally building operators have the option of using local power or using Class 2 power which is limited in the amount of power and distance reached per pair of copper. Today, Fault Managed Power Systems such as
Panduit’s Pulse Power, offers an alternative method of power to these essential communications devices. This category of power source equipment allows the operator to introduce a new level of benefits to the intelligent cabling infrastructure that will support 5G deployment, including converting standard AC to higher voltage DC power which is transformed into a pulse current across the network.
Delivered over standard multiconductor cable each pulse provides safe end-to-end power delivery up to 2km, with end point waveform conversion to 48Vdc to power multiple devices.
A major benefit of pulse power technology is that any break or shorting of the cable is automatically detected and due to its pulse
waveform, the system shuts down power within milliseconds to eliminate electrocution risk. As a centralised technology, it allows for effective battery backup, to ensure networked IoT devices have hierarchical sequenced shutdown in case of power outages.
What will be the impact of
5G on fibre optic cabling? 5G will expand the connectivity capability of every application that uses it to transmit and receive data. Therefore, 5G will expand the use of fibre optic cabling. Moreover, pulse power technology allows for cheaper cabling, such as Panduit’s small diameter 18AWG single pair copper cable to be utilised in the 5G network providing power requirements similar to the less flexible hybrid fibre optic solutions. Fibre optics is a well understood technology platform, therefore it is expected to be a consideration in increasing numbers of intelligent infrastructure plans. Likewise, pulse power’s capability to deliver fault managed power to the devices is, and will be, an alternative solution to the AC hybrid fibre solution. Applications, such as tunnels and underground facilities need a safe electrical power and pulse power delivers this. It is expected that the expansion of 5G will open up the marketplace as new solutions come to market. Fault Managed Power is an important enabler for 5G, PoE and smart buildings. We can now have a Pulse Power backbone in a building to power all the PoE switches, that provide power and Ethernet connectivity for end devices.
Will 5G affect structured
cabling in the data centre? For data centres to continue to drive down costs and find efficiencies to reduce their CO2 emissions and improve their sustainability, increased data capture is essential and 5G is an important technology in continuous remote data collection. Gartner predicts that by 2028 there will be over four billion connected IoT devices in commercial buildings, including data centres, with 5G at the forefront of data capture. Technologies that create efficient platforms for 5G in data centres, like pulse power, and add capabilities to the intelligent infrastructure increase the underlying benefits to the operators and its customers by delivering power and data efficiently, safely, and securely.
