Is LTE-U DOA?

By | August 17, 2015

Reading some of the literature about LTE-U (and LAA) leads you to believe that its deployment is a foregone conclusion: operators love it; vendors support it, and products will be available within months. But operators lack the sales channel into the enterprise where LTE-U is envisioned to be deployed and provide most value. While LTE-U… Read More »

Time for a Comprehensive Strategy for License-Exempt Spectrum

By | July 20, 2015

Calls for regulators to release more unlicensed spectrum for Wi-Fi are getting louder: the 2.4 GHz band is heavily used and the 5 GHz band suffers from many restrictions that limit its applicability. LTE’s entry into unlicensed spectrum is further amplifying these calls and adding an acute sense of urgency. But what is required is… Read More »

Microcapacity: Unbinding Wireless Capacity Through Trading Exchanges

By | July 13, 2015

Microgeneration allows one to generate electricity for own use, typically using renewable resources such as wind or solar energy. Excess energy can be sold to the power company. The arrangement helps in evening out the variability in energy consumption. It reduces the peak load requirements for the main grid while energy generated during non-peak hours… Read More »

LTE Flavors in Unlicensed Spectrum

By | June 25, 2015

Guest post by Faris Alfarhan* The unprecedented increase in demand for high-speed broadband requires a bundle of solutions to satisfy the demanded capacity. Unlicensed spectrum is increasingly considered by cellular operators, internet service providers, and businesses as part of solution set. Unlicensed spectrum cannot match the quality of licensed spectrum, as the interference profile is… Read More »

Taking Wi-Fi to Sub 1 GHz

By | December 22, 2014

The Internet of Things (IoT) is the catalyst for a number of new standards that will reshape wireless connectivity as we know it. Examples: Bluetooth LE, LTE-MTC, Zigbee, and LPWA standards. Wi-Fi (802.11) is also being reshaped to accommodate IoT applications. These applications have different requirements which make connectivity techniques for IoT fragmented. Competition is… Read More »

From LTE-U to LTE-DSA: Solving The Capacity Crunch

By | March 31, 2014

The proposal by Qualcomm to enable LTE operation in unlicensed band (LTE-U) received a warm response from some (e.g. Ericsson, Verizon) and not so warm from others especially incumbents with strong legacy in Wi-Fi in both the vendor and operator communities. The contentious issue center on co-existence of LTE and Wi-Fi in the same band… Read More »

Carrier Wi-Fi: What is it?

By | July 22, 2013

With more mobile network operators using Wi-Fi to complement their radio access networks, one begs the question: how’s “carrier Wi-Fi” different from the one I have at home? What exactly is “carrier Wi-Fi”? While there is no proper, or exact, definition for carrier Wi-Fi, I think it’s more important to realize that the definition has… Read More »

New Frontiers in Personal Communications (and Investment Opportunities!)

By | June 24, 2013

In the late 1880’s, Heinrich Hertz’s experiments with wireless signals were in the VHF/UHF bands (60 to 500 MHz). The first transatlantic transmission in 1901 by Marconi was either around 850 kHz or in the neighborhood of 100 kHz: he simply did not have reliable equipment to measure the frequency. With these modest starts, advances… Read More »

Small Cell World Summit 2013: Wireless Analytics to the Forefront

By | June 8, 2013

The Small Cell World Summit just concluded, so I would like to summarize my thoughts and impressions from this event. For a little perspective, the conference is sponsored by the Small Cell Forum, which was called the Femto Forum before it rebranded in February 2012. In alignment with this new vision, the 2013 edition of… Read More »

When Will Small Cells Be Deployed? A Case Study of Critical Strategic Planning Options for Mobile Network Operators

By | May 27, 2013

This case study was designed to help answer important questions related to small cell deployments. It is based on a traffic forecast and capacity planning tool developed to aid operator strategic planning activities. The tool can also be used by vendors and other ecosystem players to map their product offering and plan for small cell… Read More »
