The way in which data is moved via wireline and wireless connectivity is going through major transformations. The dynamics that are causing these changes are being seen across a broad cross section of different sectors.
Within our cars, the new features and functionality that are being incorporated mean that the traditional CAN and LIN based communication technology is no longer adequate. More advanced in-vehicle networking needs to be implemented which is capable of supporting multi-Gigabit data rates, in order to cope with the large quantities of data that high resolution cameras, more sophisticated infotainment, automotive radar and LiDAR will produce. With CAN, LIN and other automotive networking technologies not offering viable upgrade paths, it is clear that Ethernet will be the basis of future in-vehicle network infrastructure - offering the headroom needed as automobile design progresses towards the long term goal of fully autonomous vehicles. Marvell is already proving itself to be ahead of the game here, following the announcement of the industry’s first secure automotive gigabit Ethernet switch, which delivers the speeds now being required by today’s data-heavy automotive designs, while also ensuring secure operation is maintained and the threat of hacking or denial of service (DoS) attacks is mitigated.
Within the context of modern factories and processing facilities, the arrival of Industry 4.0 will allow greater levels of automation, through use of machine-to-machine (M2M) communication. This communication can enable the access of data — data that is provided by a multitude of different sensor nodes distributed throughout the site. The ongoing in-depth analysis of this data is designed to ultimately bring improvements in efficiency and productivity for the modern factory environment. Ethernet capable of supporting Gigabit data rates has shown itself to be the prime candidate and it is already experiencing extensive implementation. Not only will this meet the speed and bandwidth requirements needed, but it also has the robustness that is mandatory in such settings (dealing with high temperatures, ESD strikes, exposure to vibrations, etc.) and the low latency characteristics that are essential for real-time control/analysis. Marvell has developed highly sophisticated Gigabit Ethernet transceivers with elevated performance that are targeted at such applications.
Within data centers things are changing too, but in this case the criteria involved are somewhat different. Here it is more about how to deal with the large volumes of data involved, while keeping the associated capital and operational expenses in check. Marvell has been championing a more cost effective and streamlined approach through its Prestera® PX Passive Intelligent Port Extender (PIPE) products. These present data center engineers with a modular approach to deploy network infrastructure that meets their specific requirements, rather than having to add further layers of complexity unnecessarily that will only serve to raise the cost and the power consumption. The result is a fully scalable, more economical and energy efficient solution.
In the wireless domain, there is ever greater pressure being placed upon WLAN hardware - in the home, office, municipal and retail environments. As well as increasing user densities and overall data capacity to contend with, network operators and service providers need to be able to address alterations that are now occurring in user behavior too. Wi-Fi connectivity is no longer just about downloading data, increasingly it will be the uploading of data that will be an important consideration. This will be needed for a range of different applications including augmented reality gaming, the sharing of HD video content and cloud-based creative activities. In order to address this, Wi-Fi technology will need to exhibit enhanced bandwidth capabilities on its uplink as well as its downlink.
The introduction of the much anticipated 802.11ax protocol is set to radically change how Wi-Fi is implemented. Not only will this allow far greater user densities to be supported (thereby meeting the coverage demands of places where large numbers of people are in need of Internet access, such as airports, sports stadia and concert venues), it also offers greater uplink/downlink data capacity - supporting multi-Gigabit operation in both directions. Marvell is looking to drive things forward via its portfolio of recently unveiled multi-Gigabit 802.11ax Wi-Fi system-on-chips (SoCs), which are the first in the industry to have orthogonal frequency-division multiple access (OFDMA) and multi-user MIMO operation on both the downlink and the uplink.
