How Much Mobile Operators Care about Energy Consumption?

There was a noticeable increase in interest over the past several months in “Green 5G”. Energy consumption was top-of-mind for CTOs at MWC22. Different industry lobbyists released white-papers praising the energy efficiency of 5G [a few of which are misleading and even utterly wrong]. The jump in energy prices, especially in Europe, became a concern for their inflationary… Read More »

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 »

5G vs. Radio Altimeters: A Storm in a Tea Cup?

The row between the wireless and aviation industries on potential interference between 5G and aircraft radio altimeters is sounding like a storm in a tea cup! The genesis of this dispute is a report in October 2020 by the Radio Technical Commission for Aeronautics (RTCA) citing potential interference to altimeters operating in the 4.2 – 4.4 GHz band… Read More »

Is Direct Satellite-to-Device the Largest Opportunity in Satcom’s History?

The direct satellite-to-device (DS2D) market is expected to reach $35 billion by 2030, and counting 400 million average monthly subscriptions driven by 5G technology (according to NSR). This is about $7/month. This highlights a very sensitive business case: constellations cost billions to deploy and operate; they need a refresh every 5-10 years. With much of the world’s unconnected… Read More »

The SIM Factor in Private Wireless Networks

Last year, I outlined several challenges facing enterprise private wireless networks (here). In this post, I wanted to highlight the role of dual SIM phones and eSIM technology in enabling private wireless networks. The SIM impacts how subscribers access the private network and, consequently, the quality of experience which makes the SIM a critical part of enterprise networks.… Read More »

Can 5G Bridge The Urban-Rural Digital Divide?

Since Covid further exposed the rural digital deficit, many have asked to deploy 5G to provide broadband services in rural areas. Many others are skeptical for various reasons. To sort through the issue, We were commissioned to investigate how 5G can bridge the urban-rural digital divide. In our paper (download here), we review some of the technical characteristics… Read More »

Latency in LEO Satellites vs. Terrestrial Fiber

Latency is a key differentiating parameter for new communication networks such as LEO satellite constellations and 5G. The interest in latency has increased as the value proposition for these networks hinges on enabling latency-dependent applications. This got some competing technology options nervous. For instance, LEO satellites provide as much as 20x round trip delay advantage over GEO satellites.… Read More »

5G Power Consumption: How mmWave and C-Band Compare

At the conclusion of the C-Band auction, I wrote that deployments of millimeter wave technology would largely stop. Even as Verizon reaffirmed its commitment to deploying mmWave, I believe that these plans would be downscaled in due time. This is because the cost for mmWave would strongly suggest this direction. Over the past week, many had questions on… Read More »

Could Wireless Networks Serving Industry 4.0 Applications Succeed without Automation?

A couple of years into 5G roll outs, the main question for operators remains on how to monetize the 5G network investments. Operators understand that enterprise wireless networks are a potential source of revenue. Many of them, from around the world, have engaged in trials testing 5G networks in enterprise settings. The trials have uncovered the complexity and… Read More »

The Synergies Between LEO Satellite Constellations and Submarine Cables

I’ve been exploring the impact of LEO satellite constellations on the wider telecom industry. Depending on the sector, the rise of LEO satellites is either complementary or competitive. Sometimes, the synergies are not evident. At other times, the competitive nature is masked by nascent requirements and emerging applications that could be game changers in the future. Underlying this,… Read More »

Land-Space Internet Convergence

The advent of non-geostationary satellites (NGSOs) has raised the issue of convergence with land-based networks. The question centres on how to provide users with services across different networks efficiently and reliably. Until now, satellites offer distinct service model defined in its own silo. With a converged land-space Internet, services could extend across multiple networks to leverage the one… Read More »

Canned RAN: A Stage Towards Open RAN Maturity

A trend is taking shape where open RAN is made of canned solutions – I call this Canned RAN. The concept of interoperable RAN elements is yielding the path for a subset of integrated solutions from a few vendors that plan to dominate the open RAN market (additional perspective here). After a couple of years of initial buildup,… Read More »
