Will 5G Be Irrelevant?

Is 5G Irrelevant?Last week I had the privilege to discuss the latest wireless industry trends with colleagues at the RAN and Backhaul conference. We discussed 5G in addition to host of other topics ranging from architecture to virtualization and much in between: spectrum, Het Nets, IoT, etc. As I contemplate the proceedings, I came to wonder about the relevance of 5G!

Today, the focus is on developing consensus on what 5G is and will be: what are the applications and which use cases will it serve? Which technologies and architectures will be best to meet the objectives? Which spectrum it will operate in?  What type of physical layer it will employ? These are but a few questions the ecosystem is debating. But what everyone agrees on is that 5G will support IoT connectivity for a great number ‘things’ in addition to providing better than ever personal broadband connectivity services.

How Small Cells Are Reshaping The Wireless Landscape

Small CellsThere’s much talk about small cells these days – on industry news sites, at conferences, in corporate announcements. This is not surprising given that mobile traffic doubles every year and, according to Cisco, will grow at a compound annual growth rate (CAGR) of 78 percent from 2011 to 2016. Wireless network architecture has relied greatly on macrocells, but with the advent of the small cell era, how will small cells shape the wireless landscape? To answer, consider the following: Read more of this post

Small Cells and the Predictability Challenge

Opinion: Small Cells and the Predictability ChallengeAnyone closely involved with small cells base station could not have failed to notice the contentious debate on backhaul capacity requirements. On the one hand, vendors of millimeter wave equipment advocate the need to support peak capacity figures, while on the other hand, vendors of other types of backhaul solution including point-to-multipoint systems point that the peak is rarely if ever achieved in practice.

In Focus: Interference in the 2.4 GHz ISM Band

WiFi/ISM Band InterferenceIn my previous blog entry, I set out to answer the question of how much WiFi is deployed. Here, I like to focus on the question of interference.  Unfortunately, I think there are fewer studies that characterize WiFi usage and interference than there ought to be. I will show here a few of the results and conclusions and present my own model and take on interference.

How Much WiFi Is Out There?

How much WiFi is out there?The success of WiFi is nothing short of outstanding. Who would have thought that wireless network operators would adopt the technology and deploy WiFi access nodes in their tens of thousands to off-load their wide area networks? But with more carrier WiFi being rolled out in addition to your typical enterprise and personal access nodes, how much WiFi is out there? How much interference does it generate? And what does that say about the future when it comes to unlicensed band spectrum utilization? Read more of this post
