The feasibility of frequency spectrum sharing arrangements is becoming increasingly of interest to ICT regulators for many reasons. Among these reasons, two standout. First, the frequency spectrum requirements to deliver broadband services is getting larger. This requires opening new frequency bands where existing users have legitimate needs. Second, the utilization of spectrum varies widely in… Read More: Guidelines For Frequency Spectrum Sharing »
Key Takeaways Quantum computing decimates RSA cryptography which underpins most of our digital platforms: you can’t have a happy quantum computing world without first protecting all of the critical infrastructures against quantum-enabled attacks. The quantum threat development is not gradual and can come suddenly to break everything. This can come fast to threaten our networks… Read More: Taking the Quantum Leap: How quantum technology is set to… »
The decision by AT&T to host its network cloud, including the core network, on Microsoft Azure Cloud is the single most important milestone in the telecom industry over the past few years. It’s an experiment and a leap of faith that is set to have major ripples on the market. The core network is the… Read More: How Telcos Outsourced Their Brains! »
FCC Auction 110 for 100 MHz in the 3.45 GHz band is set to start tomorrow (October 5): the third auction for 3 GHz band spectrum in less than two years for a combined 450 MHz. This is a huge amount of spectrum considering previous auctions and holdings. Here, I wanted to share an outline… Read More: Overview of FCC Auction 110 in 3.45 GHz »
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… Read More: The SIM Factor in Private Wireless Networks »
Two things led me to write this post. First, much of what’s written about 6G focuses on what 6G could be, but little arguing for why we need 6G! Second, 5G offers a very flexible architecture and a rich roadmap which will need many years to fully develop and use. These two reasons makes the… Read More: Why We Need 6G! »
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… Read More: Can 5G Bridge The Urban-Rural Digital Divide? »
The Canadian auction for an average of 111 MHz in the 3500 MHz band raised a record setting C$8.91 billion (US$7.16 B). That’s an average of C$2.28/MHz-PoP (US$1.83); or a global record high for this spectrum band. Or, to bring another meaning into this, operators paid C$270 for each mobile subscriber! For another perspective, the… Read More: A Gold Medal in Spectrum Auction Valuation: 3500 MHz Canadian… »
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… Read More: Latency in LEO Satellites vs. Terrestrial Fiber »
The market landscape and auction structure make the Canadian 3500 MHz midband spectrum auction an interesting one to watch. The auction will kick off on June 15 to release an average of 111 MHz of which around 50 MHz will be set aside for regional wireless operators. This is relatively small in terms of what… Read More: Dynamics of the Canadian 5G Midband Spectrum Auction »

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… Read More: 5G Power Consumption: How mmWave and C-Band Compare »
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… Read More: Could Wireless Networks Serving Industry 4.0 Applications Succeed without Automation? »
