Each generation of Wi-Fi arrives like the tide, slowly building up, not arriving all at once, but unstoppable nevertheless. Cisco has been preparing for Wi-Fi 6 for some time now. The standard is finalized. 802.11ax (aka Wi-Fi 6) certification of radios, access points, and controllers is underway. Manufacturers are busy incorporating Wi-Fi 6 chipsets into their new products.Whether your organization is expanding with new buildings, adding employees, or moving to cloud services, upgrading to Wi-Fi 6 will provide many immediate benefits and prepare for future growth.
The Internet of Things promises a transformative impact on a wide range of industries, but along with that promise comes an enormous new level of complexity for the network and those in charge of maintaining it. For the major mobile data carriers in the U.S., that fact suggests an opportunity. This article looks at the pros and cons of letting the carriers take on the burden of IoT implementation.
According to the World Economic Forum, cyberattacks are one of the top 10 global risks of highest concern in the next decade with an estimated price tag of $90 trillion if cyber-security efforts do not keep pace with technological change. The next victim of cyberattacks could be buildings. Digitising buildings is a major trend, but it comes with new security issues, according to Frost & Sullivan’s IT/OT Security Convergence for Building Technologies report.
Ever since the invention of single mode fiber optic cable decades ago, the industry has continued to develop new ways of increasing the amount of data that can be transmitted over an optical fiber link. Two significant developments have improved fiber utilization: (1) the simultaneous transmission of multiple lasers of different wavelengths over a single fiber — a technique called wavelength division multiplexing (WDM), and (2) coherent transmission using digital signal processors (DSPs) to modulate and detect multi-levels in both phase and amplitude of laser light on two polarizations, resulting in increased spectral efficiency. This white paper reviews the technological advancements that have increased the capacity of information that can be transmitted over a single mode fiber link and discusses how parameters in coherent transmission such as modulation order, baud rate, and transmission shaping determine overall fiber capacity.
Latency times associated with existing infrastructure is approximately 100 milliseconds. Some services, such as online HD video streaming, need latency reduced by up to three-times to be properly functional. This issue can be mitigated by locating the physical infrastructure closer to the source data and in turn providing higher bandwidth: Edge computing.
Data center operators and facility managers continuously work to ensure temperatures remain consistent without raising energy bills. With so many options on the market, it can be hard to decide which one is the best. Beating data center heat is possible, though, and here are four ways to do it: Employ regularly scheduled maintenance, optimize server racks for cooling efficiency, rethink your data center architecture, and increase data center temperatures.
Active optical cables (AOCs) are used for short-range multi-lane data communication and interconnect applications. Usually, the wire transmission of optical communication should belong to passive part, but AOC is an exception. AOCs consist of multimode optical fiber, fiber optic transceivers, control chip and modules. They use electrical-to-optical conversion on the cable ends to improve speed and distance performance of the cable without sacrificing compatibility with standard electrical interfaces.
The demands of new and emerging technologies – things like 5G, BIoT and DAS – present both opportunities and challenges for enterprise fiber networks. Until recently, multimode transceivers were orders of magnitude less expensive than their single-mode counterparts, making multimode the fiber of choice for many enterprise network designers. Today, the cost of single-mode transceivers has come down significantly, making the increased bandwidth and longer distances made possible by single-mode fiber much more attractive. This presentation discusses why you may want to include single-mode fiber in your enterprise network.
Everstream is building an enterprise grade fiber network to support Milwaukee and its businesses as they scale and grow in the coming years. The build-out also includes the construction of new small cell sites to provide high-bandwidth connectivity to the city and businesses. This will deliver the increased bandwidth and data required to support the upcoming 2020 Democratic National Convention (DNC).
Technology can’t be an afterthought for new builds. Here’s how architects and developers can ensure that their new builds are intelligent from the outset.
