NTT Docomo names suppliers for 5G trials; targets 2020 commercial launch

NTT DOCOMO  May 9, 2014 Microwave Journal NTT Docomo, Japan's biggest mobile operator, announced it is working with six suppliers to conduct various “experimental trials” for 5G involving higher frequency bands than those used for existing mobile technologies. The six vendors involved are Alcatel-Lucent, Ericsson, Fujitsu, NEC, Nokia and Samsung. NTT Docomo is targeting commercialContinue Reading

“No-one really knows what 5G is”…GSMA talks about the Future of Mobile, at TM Forum Live!

AMDOCS Blogs Naomi Weiser | June 6, 2014  “No-one really knows what 5G is. We need to spend some time defining it”.  Since the person making this declaration at TM Forum Live! this week about the next (fifth) generation of mobile broadband technology to come was Anne Bouverot, Director General of the GSMA (and she,Continue Reading

CTIA reports 120% growth in wireless data traffic

June 17, 2014: The CTIA reported a 120% increase in US wireless traffic in 2013. Their annual survey results includes historical anonomized data from all the major US wireless operators http://www.ctia.org/resource-library/press-releases/archive/ctia-annual-survey-2013. The previous annual report for 2012 showed a moderating growth rate of 67% which suggested a less than exponential growth rate. However, yesterday's report shows accelerating growth to 120%Continue Reading

Leading global Operator, Vendor and Research representatives gathered to review the initial results of the Alliance’s 5G initiative and to give guidance on the way forward. Earlier this year, theContinue Reading

Latency in 5G, Legacy in 4G

Latency in 5G, Legacy in 4G Don Brown & Stephen Wilkus   In developing wireless 5G standards, we have an opportunity to further reduce latency, the time delays, in future wireless networks.  In fact, there appears to be unanimous opinion that 5G standards should have less than 1 millisecond (msec) of latency.[1],[2],[3],[4] But why? InContinue Reading

A Critique of Pure Speed

A Critique of Pure Speed or What do we mean by increasing data rates? Surely the next generation of wireless standards will support higher data rates, but which data rate? We need to make sure that we solve the problems that need solving, rather than simply doing more of the same of what we’ve foundContinue Reading

Be careful what we wish for

Some are coming to the 5G table with frequency band proposals for mm-wave propagation measurement campaigns. Some are coming to the 5G table with extrapolations of wireless data usage and talk of 5000x more demand.  Some are coming to the 5G table with immense financial commitments with hopes of gaining jobs or constituencies. The TIA brought about 50 interestedContinue Reading

A frequency is not a network

Millimeter waves and generally radio frequencies above 6 GHz are increasingly recommended for 5G wireless applications. Much of the recent IWPC white paper on 5G (http://www.iwpc.org/whitepapers.aspx#5000x), and April’s Brooklyn 5G Summit (http://brooklyn5gsummit.com) hosted by NSN at New York University’s wireless research center have been concerned with the use of frequencies above 6 GHz, perhaps wellContinue Reading

New Journal Articles on 5G Concepts

The following research articles have recently been published (typically in peer reviewed journals) that may be of interest in the academic depths of 5G concepts. In some cases, 5G is not expressly mentioned but this editor sees relevance to the next generation wireless system proposals.   Wang, Cheng-Xiang, et al. "Cellular architecture and key technologies forContinue Reading
