ANALYSIS & OPINION: NEXT GENERATION NETWORKS
PoE can offer benefits from time and cost savings, to increased flexibility, safety, reliability and scalability
solution, compared with running power cables in proximity to data cables. Tis can lead to the creation of noise in the network, which can reduce efficiency. In contrast, structured cabling takes such instances into account from the start, and helps achieve structured network setup. It is also flexible, reliable and highly efficient for moving, adding and changing the infrastructure as the network grows. Other benefits include: easy scalability and adaptability to future growth needs; ease of installation, repair and replacement; a standardised and modular design enables quick and easy replacements and upgrades; easy integration and support to multimedia content and enterprise solutions, such as video conferencing; unified and modular cabling helps easily diagnose faults and monitor the network; overall higher returns and improved efficiency. On the other hand, using a unified cable
medium, and transmiting signals with a common protocol, allows data single point control and data analysis features. And the potential cost savings are prety impressive too. Service providers can expect pathway material savings of around 40 per cent, labour savings of up to 30 per cent and maintenance cost savings of nearly 15 per cent.
Power over Ethernet Tis is where PoE steps in, offering a range of benefits from time and cost savings, to increased flexibility, safety, reliability and scalability. PoE, which lets network cables carry electrical
power, is a popular LAN switching technology. It helps provide DC power at end points over copper Ethernet cables. DC power is transmited from power sourcing equipment over the existing twisted pair Ethernet cable. Tis twisted

pair Ethernet cable enables connectivity in the powered devices, such as IP phones, video cameras, wireless access points, point-of-sale machines, access control card readers, LED luminaires, and other industrial and building automation applications. Tis technique helps in reducing the capital expenditure, bringing down the overall total cost of ownership of the project. Te new IEEE 802.3bt standard, which was
ratified in September last year, further increases the potential of PoE – offering a host of other capabilities, including support for highly efficient four-pair power delivery, and channel definitions for 2.5Gb/s, 5Gb/s, and 10Gb/s PoE operations. It also boosts the maximum power that PSE is capable of by a factor of three – expanding it from 30 to 90W – and elevates the power level for powered devices to 71.3W. In addition, IEEE 802.3bt doubles the number of supported classes from four to eight, addressing Type 3 and 4 devices for both power sourcing equipment and powered devices between 4 and 90W and 3.84 to 71.3W respectively. Tanks to PoE’s advantages, it can support
data transfer rates of up to 5Gb/s over Cat6A and beyond, up to a range of 100m – making it ideal for triple-play services. High-definition video streaming only requires 400Mb/s, meaning a PoE-based network has the potential to effectively stream an HD training video, while others work and talk over VoIP. PoE can take Li-Fi technology a step further,
as it finds use cases from traffic light systems to retail, oceans and aircraſt carriers. It offers exciting use cases as Point of Sale (PoS) systems/ PoE powered helpdesks in locations such as shopping centres and hotels. PoS systems has the potential to add 10 to 40 per cent more sales in a targeted area. PoE+ enabled VoIP, dense
wireless internet access points and PoE-powered IP surveillance cameras are other similar use cases.
End goal Growing consumption of data in enterprises and homes are critical elements for the adoption of PoE. With the ability to bring high-bandwidth data and power to multiple devices and network assets, the technology can be adopted by a range of applications, including security cameras, lighting, building automation, control systems and wireless LAN access points. By transmiting power and data via a single
networking cable, PoE eliminates the expense of installing additional electrical circuitry. By relying on PoE to deploy LED lighting and existing LED lights to transmit Li-Fi, PoE can easily be used to power Li-Fi. It also has scope in vertical markets, such
as citizen services, connectivity in public transportation, higher education and healthcare, and is already being used in commercial workspaces for VoIP and video conferencing. In summary, we believe that PoE is a game-
changing technology for connectivity markets and will play a critical factor in shaping the network ecosystem of tomorrow – with prevalent conventional cabling techniques still in use, the market is expected to be huge. Add to this the potential of advanced PoE+ and PoE++ systems to offer multiple-facility systems, that help to lower carbon emissions and provide beter facility management – also with enhanced energy savings. All these emerging applications for commercial spaces, healthcare, finance and retail sectors can bring significant impacts in the near future. n
