Image: Sunshine Coast Council The Sunshine Coast Council has announced the completion of its AU$7. 2 million cable landing station at Maroochydore that will house the connection of the AU$35 million Japan-Guam-Australia subsea system. The landing station, which was built by Vertiv, is located adjacent to the new Maroochydore city centre, a 60-hectare area that is being developed into a commercial, retail, medium and high density residential development area with new road transport, public open spaces, community facilities, and infrastructure. With capacity for four submarine cables and electricity supplied from two different sources, the new station also features 24 data cabinets, 20 security cameras, and two 500 KVA back-up power generators. Sunshine Coast Council Mayor Mark Jamieson said the completion of the cable landing station puts the delivery of the Sunshine Coast cable closer to being completed. "Unlike traditional cable landing stations that are normally non-descript buildings out of view from the general public, our landing station is designed to reflect council's design vision for the Maroochydore city centre, " he said.
Facebook engineers have developed a new robot that winds fibre-optic cable around existing medium-voltage (MV) power lines, enabling the cost-effective expansion of high-speed internet infrastructure. The robot holds specially designed cables within it which are much thinner and lighter than traditional cables. This allows it to lay up to one kilometre of cable by wrapping it around existing MV lines. It also has an articulated design allowing it to move over insulators and other impediments on the line without human interaction. The largest costs associated with building new fibre networks lie within the construction of new poles and other infrastructure that can be largely eliminated with the new robot. As of 2019, over 70 per cent of the world's population lives more than 10km from a fibre connection, resulting in lower internet speeds and higher latency. With the demand for data increasing year-on-year in both developing and developed nations, the robot could help to close this gap in a relatively short time frame and at low cost.
A network of 60 communications satellites was sent into orbit around the Earth aboard a SpaceX Falcon Heavy rocket on on May 23. The craft are the first in a planned fleet of 12, 000 such objects, designed to provide high speed internet connections to homes and businesses back on the surface. Over the summer, SpaceX had lost contact with three Starlink satellites orbiting earth, leaving experts concerned over the potential for such satellite mega-constellations to add to dangerous orbiting space debris. Elon Musk envisions Earth's orbit swarming with SpaceX's Starlink satellites (pictured is a simulation of Starlinks blanketing Earth with broadband) The California company will have a total of 42, 000 if the proposal is approved and it plans to launch hundreds, potentially thousands, into our orbit over the next year But this does not seem to put a damper on Musk's plans. The billionaire is set to release hundreds or even thousands of the satellites into orbit over the next year. SpaceX's recent filing provides details about frequency usage, proposed orbital altitudes, and the number of satellites it desires.
Facebook believes it could allow fibre to be deployed "within a few hundred metres of much of the world's population". The cable itself proved to be a significant engineering challenge as traditional fibre cables could be subject to degradation phenomena from the MV lines "such as tracking, partial discharge and dry band arcing", Facebook said. The MV lines can also reach high temperatures that would melt through traditional cables. To solve these issues the engineers developed a "specially tailored aramid configuration and a high-strength, high-temperature, track-resistant polymer jacket" that will allow the fibre cables to operate in this hostile environment. The robot used to lay the cable includes a vision system to identify obstacles and appropriately adjust its movements to clear them, while maintaining the clearances required to prevent an electrical hazard. Facebook believes each robot should be able to lay between 1. 5km to 2km of fibre per day, allowing for rapid rollout of high-speed internet infrastructure.
Later versions of Ethernet would use the same framing but switch over to using 10BaseT (twisted pair, commonly known as Cat-5 or Cat-6 cables) or even fibre optic cables. Ethernet frames include a CRC (Cyclic Redundancy Check) error code, which permits computers to discard packets that have had errors introduced during the encoding, delivery, or decoding of the packet. The draft version of Ethernet used a 16-bit CRC, but the version 1. 0 upgraded it to a 32-bit CRC, which is still in use today. Modern network cards use hardware to calculate and verify the CRCs of Ethernet packets automatically, and invalid packets are silently dropped. Because the CRC is over the contents of the Ethernet frame, it forms the last part of the packet. The body of Ethernet packets are variable lengths, and while the initial draft started off with 500 bytes of data, it was upgraded in the Ethernet 1. 0 specification to allow for a variable length data field between 46 and 1500 bytes in size. Together with the header and checksum, it means that the Ethernet frame is between 64 and 1522 bytes in size.

And hours later, he shared 'Whoa, it worked' – sending the internet into a frenzy Some users were excited that the satellites have successfully performed and praised Musk for the achievement Some users were excited that the satellites have successfully performed, while others were skeptical about Musk's announcement. The CEO filed paperwork with the International Telecommunications Union for the operation of 30, 000 more Starlink satellites earlier this month, which would bring the count up to 42, 000 if approved. SpaceX plans to launch hundreds, potentially thousands, into our low-orbit over the next year. However, critics have warned that the Starlink project, and others like it, will lead to light pollution - in the form of streaks that can already be observed from here on Earth. While others were skeptical about Musk's announcement Musk filed paperwork with the International Telecommunications Union for the operation of 30, 000 more Starlink satellites earlier this month, which would bring the count up to 42, 000 if approved Musk has high hopes for his satellites, by experts in the past has condemned it over fears it will blot out the night sky and make scientific research more difficult.
Smart cities like Singapore, for example, are laying high-speed fibre infrastructure as the foundation of its next-generation nationwide broadband network capable of supporting IoT devices and applications well into the future. This fibre infrastructure extends to converged networks inside buildings – Ethernet or fibre backbone carrying voice, data, video and wire-less traffic. A converged infrastructure also creates opportunities to integrate real estate; IT and building management and facilities applications. Converged connectivity Further, demand for ubiquitous Wi-Fi connectivity and the rollout of 5G services and applications in populated urban areas require targeted, localized small cell densification. This need for higher network density elevates the importance of crosshaul and backhaul, as many smart building applications and services depend on extremely low latency, an ad-vantage only found in advanced fibre infrastructure. Deploying an optimized converged network in advance can help to reduce the net cost of fibre-optic crosshaul and backhaul significantly.
Matching the evolution of smart building networks, three consistent needs have emerged in efforts to boost efficiency, mobility and security in a smart city: Mobile connectivity and ubiquitous wireless coverage for network access anywhere; Convergence of disparate networks onto a unified IP over Ethernet physical network layer for simplicity, security, and adaptability to connectivity changes and bandwidth demands; and A future-ready infrastructure foundation to support the still-evolving, ever-growing Internet of Things (IoT) efficiently. Planned connectedness Already, a network of Internet of Things (IoT) devices and sensors connected to data centres are generating data that fosters analytics, intelligence and insights for smart city applications and services. An estimated 24. 1 billion IoT devices will be connected globally by 2030. IoT-enabled applications and services such as connected transit and bike shares, smart parking, connected CCTV, smart lighting and smart locks make smart cities, campuses and buildings safer and more efficient to manage.
