Dark fiber has re-emerged as the latest fashion trend in the wireline telecom industry, and is primarily targeted at wireless backhaul, enterprise customers and traditional carriers. For wireless carriers, dark fiber lets them maintain complete control over their service experience, meaning if they want to increase capacity, they can do it on their own timeline. Special report
Exalt Communications may be long gone, but its successor, Exalt Wireless, is in for the long haul. So says the company's CEO, who's still bullish on the company's long-term prospects.
A group of researchers from Chalmers University of Technology in Gothenburg, Sweden, and Ericsson is getting recognition for setting a new world record in wireless data transmission rates using a new type of microwave circuit.
Verizon Wireless' push to use dark fiber as its wireless backhaul medium has both positive and negative aspects, according many wholesale service providers serving the wireless industry. Dark fiber allows wireless carriers to maintain complete control over their service experience, meaning if they want to increase capacity they can do it on their own timeline.
Fastback Networks said its backhaul radio is now capable of throughput exceeding 800 Mbps up to a distance of 2 kilometers, whether in line-of-sight (LOS), near-line-of-sight (nLOS) or non-line-of-sight (NLOS) conditions.
A year ago, Mimosa Networks was still firmly in stealth mode. But the Campbell, Calif., company has now released its first last-mile gigabit wireless radio for Internet service providers seeking fiber speeds delivered over the air.
Cambium Networks announced products designed to operate in the 5150-5250 MHz frequencies that the FCC recently opened for fixed outdoor wireless use.
AOptix announced that its Intellimax wireless transport product, which combines free-space optics and millimeter-wave links, is being deployed for evaluation by the National Aeronautics and Space Administration (NASA) at the Kennedy Space Center in Cape Canaveral, Fla.
Though the Open Networking Forum (ONF) is still in the early days of specifying requirements for wireless transport through its Wireless and Mobile Working Group, which was announced in January, early virtualized backhaul solutions could be ready for trials in 2015 with production products arriving in the 2016-2017 time frame, according to Ran Avital, vice president of strategic and product marketing at wireless hauling specialist Ceragon Networks.
Wireless operators seeking ways to automate and optimize their mobile backhaul use will invest more than $700 million yearly in self-organizing network (SON) technology by the end of 2020, estimates SNS Research. Mobile backhaul-related SON revenue is expected register a compound annual growth rate (CAGR) of 48 percent between 2014 and 2020.
