Enterprise Private Wireless Networks: 4G or 5G?

In almost every enterprise private wireless network (PWN) engagement, I come across the question of what technology to select: 4G/LTE or 5G1? Deciding between LTE and 5G is often complex and needs careful analysis. Here, I outline the top 5 factors to help in the decision making process. 1. Performance & Features The PWN has to meet the… Read More »

The Case for Network Automation: Application to Power Consumption

Integrated AI-based technology enables networks to adapt autonomously which helps operators optimize their service delivery to consumers and enterprises. As communication networks increase in complexity, operators seek to simplify operation and maintenance activities and reduce operating costs. Network automation could help operators achieve this objective. Automation is not a new concept: it has been around under different names… Read More »

The True 5G Value Proposition: It’s not about Speed and Latency!

It is common to pin the 5G value proposition on its performance, mainly capacity* and latency. These features will enable applications that operators can monetize. However, I will argue here that capacity and latency are secondary to realizing the full 5G value proposition. Capacity and latency make for big headlines and are easy to grasp by the common… Read More »

Is 550 million 5G subscribers in 2022 Too Many?

Will there be 550 million 5G subscribers in 2022 as Ericsson forecasts in its latest mobility report? I highly doubt it – here’s why. LTE is a very successful technology that commercially began to roll out in the US, Japan and Korea in 2010 timeframe. Today, it includes over 520 live networks and over 1.3 billion subscribers (1.7 b per Ericsson’s… Read More »

The Future of 5G: Risking Disappointment?!

Monitoring the progress of 5G at the recent 5G Americas analyst summit, where carriers including AT&T, T-Mobile and Sprint engaged industry analyst on many 5G topics, I noted few observations. For context, the industry remains fixated on capacity: how to scale to support 11 GB in 2019 from ~4 GB monthly usage? This is fuelling the drive towards millimeter… Read More »

What Capacity Problem?! A View on the Small Cell Market.

Small cells have existed and been talked about for about a decade now. The technology and market went through different phases tracking 3G, LTE and now 5G technologies. Yet, the deployment of small cells has been timid and numbers fall below expectations. The fundamental thesis behind small cells is that demand for capacity exceeds supply. The market speculated that… Read More »

Midterm Observations on the Telecom Industry.

Three events were held this past week that provided an opportunity to get a midterm pulse of the telecom industry: the MWC-Shanghai, 5G World and WBA Congress. Having attended the last two, I wanted to summarize a few observations: * The vision for 5G is converging; industry is aligning along common themes.  A few leading operators are racing to claim 5G capability… Read More »

Does the Short Road to 4.5G Mean a Long Road to 5G?!

Browse through industry literature or conference proceedings and trade shows, and you’ll be inundated with talk about 5G. On the other hand little is to be found on “4.5G”, or technically speaking, LTE Release 12 and 13 branded as LTE-Advanced Pro [which incidentally I find to be a bad choice of terms that I prefer to use 4.5G even… Read More »

MNOs Investments in LPWA: Strategic or Tactical Expediency?

Over a year ago, SK Telecom invested in SigFox in a round that raised €100 m from a consortium of investors that included Telefonica and NTT Docomo. This week, SKT announces that it will build a LoRa network at a cost of more than $84 m over two years. In the meantime, SKT is working with Ericsson to evaluate the… Read More »

Is IoT at Risk of Stalling?

The wide-area IoT connectivity battle which has been brewing for a couple of years is heating up. Early last month at CES, Ericsson announced the release of “the first complete cellular low-power wide-area (LPWA) solution” to AT&T. At the same time, the Wi-Fi Alliance branded 802.11ah as Wi-Fi HaLow targeting applications in smart home, connected car, digital healthcare, industrial, retail, agriculture, and… Read More »

Will Operators Deploy Phase 1 5G?

Standardization of 5G is split into two phases. The first phase, which is scheduled for 2H2018, will focus on a subset of use cases and features. The second phase which is scheduled for December 2019, will meet ITU2020 requirements for 5G technology. Phase 1 will also focus on sub 6 GHz bands although carriers in Asia are pushing… Read More »

Which IoT Technologies Will Die Out?

IoT use case are fragmented with different requirements. To match these requirements, a number of IoT connectivity solutions are available including wide-area low-power (LPWA), cellular wireless technologies (EGPRS, UMTS, LTE of different varieties), and short range technologies adapted to cover wide areas through mesh networking (ZigBee, WirelessHART, etc.) or extension of point-to-multipoint technologies (e.g. 802.11ah/HaLow). Each of these… Read More »

5G: Revolution or Evolution?

Is 5G an evolution or a revolution? In an earlier article I said 5G is an evolutionary stage. Many disagreed: 5G is a revolutionary technology. But this is all a matter of perspective.  The evolution vs. revolution debate has largely focused on the air interface, or the ‘subscriber interface’: everyone wants to have fast wide-bandwidth connectivity. Naturally, it is the… Read More »
