Unlicensed Spectrum: More Capacity, Flexibility

0
In an earlier post I discussed the FCC’s recent decision to open up 150 MHz of spectrum in the 3550-3700 MHz band for unlicensed “General Authorized Access” usage as the lowest-priority usage category in a new three-tier model that includes protections for incumbent government users and provides for “Priority Access Licenses” assigned via auction. In this post I’m going to briefly review two other spectrum bands that the FCC has recently moved to make more available for unlicensed use. Together these changes have potential to increase unlicensed spectrum capacity and flexibility in terms of network designs and business models. 5 […]

The FCC’s 3.5 GHz Tiered-Use Plan: Paradigm Shift, Experiment or Both?

0
In a series of posts over the past two months I’ve discussed a range of initiatives aimed at using unlicensed spectrum to support the growing demand for wireless connectivity. To put these efforts in a forward-looking context, it’s helpful to get a sense of what changes are in the works in terms of expanding the amount of spectrum available for unlicensed use. In this post I’m going to focus on the most recent development on this front: the FCC’s April 17 decision to make 150 MHz of spectrum (3550-3700 MHz) available for new licensed and unlicensed commercial use, while retaining […]

Detroit Digital Stewards: Unlicensed Open Source Neighborhood Networks

0
In a series of posts over the past two months, I’ve looked at efforts by private companies and city governments to use unlicensed spectrum to improve choice, affordability, innovation and service quality in the communications sector. In this post I’ll add another type of entity to the mix of unlicensed spectrum innovators: local neighborhoods, where issues, interactions and initiatives tend to be more personal and place-based. One focal point for this kind of neighborhood-driven network initiative is Detroit, a city facing severe financial constraints and one of the nation’s lowest levels of Internet penetration (see tables in this earlier post).

Google’s Project Fi + Free Muni Wi-Fi = Customer Savings + Carrier Disruption

0
Yesterday Google officially announced Project Fi, its much anticipated wireless service, which I’ve previously blogged and tweeted about during its pre-announcement rumor/leak phase. Now that more details, including pricing, are available directly from Google, an updated post seems in order, especially following recent posts about newly launched municipal Wi-Fi services in NYC and Boston (later on this post I’ll consider how these two developments may be related and synergistic). As expected, Google’s wireless service will route user traffic over a mix of Wi-Fi connections and, via MVNO arrangements with Sprint and T-Mobile, the two carriers’ cellular networks. This “three network” approach alone […]

LinkNYC: Free Muni Wi-Fi with Big Apple Style & Ambition

0
In my last post I described Boston’s recently-launched Wicked Free Wi-Fi as a new generation of municipal wireless networks likely to be more successful than the first generation of projects launched a decade earlier. Another member of this new generation is LinkNYC, a recently announced Wi-Fi network that will be deployed in New York City starting later this year. While they have some things in common (i.e., a focus on free outdoor nomadic service), the NYC project is, in key respects, different, more ambitious and perhaps more controversial than Boston’s Wicked Free. As Matthew Flamm put it in the lead […]

Boston’s “Wicked Free Wi-Fi”: A New Model for Municipal Wi-Fi?

0
In my last post I briefly reviewed the less-than-stellar history of municipal Wi-Fi networks that were deployed roughly a decade ago. As I noted in that post, these projects employed earlier generations of technology and often-poorly-conceived “public-private partnerships.”  And, importantly, they were launched well before the combination of smartphones/tablets and data-capped LTE/4G mobile services had turbocharged demand for nomadic Wi-Fi connectivity. In this post I’m going to focus on an example of what I consider a new generation of municipal Wi-Fi networks, Boston’s Wicked Free Wi-Fi service, which the city formally launched in April. As reported by Michael Farrell in […]

Community WiFi in the Smartphone Era: lessons & differences from the past

0
So far, this series of blog posts has focused on what private companies are doing in the unlicensed spectrum space—including startups, cable operators, Google and mobile carriers. In the next few posts I’ll consider what cities and local neighborhoods have done, are doing, and are planning to do with unlicensed spectrum. As a first step in considering current and future “community WiFi” projects, it’s worth taking a look back at an earlier wave of municipal WiFi networks. These date back roughly a decade, with one of the most ambitious early projects, in Philadelphia, being announced in April 2005, just a […]

Signs of Google’s Global Ambition for Project Nova

0
In a post yesterday I discussed the disruptive potential of Google’s Project Nova. Having just discovered an article by Christopher Williams published last weekend in the UK’s Telegraph, I thought I should add an update on international aspects of Nova’s ambitions and potential impacts. Williams reports that, according to industry sources, “Google is in talks towards a deal with Hutchison Whampoa, the owner of the mobile operator Three.” He also notes that “Google and Three declined to comment.” The two giants are discussing a wholesale access agreement that would become an important part of Google’s planned attempt to shake-up the […]

Unlicensed Spectrum: A Look at Google’s Project Nova

0
Though Google has not revealed much in the way of details, the Internet search giant is expected to launch a WiFi/MVNO wireless service sometime in the near future. Based on limited comments from company executives and reports in the Wall Street Journal (see here and here; subscription may be required) and elsewhere, it seems that the service will: rely on a combination of WiFi connectivity supplemented by cellular connections provided via MVNO agreements, most likely with both T-Mobile and Sprint; initially be available only to owners of the Nexus 6 smartphone, built by Lenova’s Motorola unit, which was acquired from […]

Some Clarification on LTE in Unlicensed Spectrum

1
After writing two posts on potential carrier use of LTE technology in unlicensed spectrum (see here and here), I came across some information that helps clarify the functionality of and relationship between LTE Unlicensed (LTE-U) and License-Assisted Access (LAA).  In those posts I referred to these as if they were different names for the same technology. A more accurate statement would be that: 1) LTE-U is an earlier iteration of “LTE in unlicensed spectrum” technology that conforms to the less stringent spectrum sharing requirements of countries like the U.S., South Korea, China and India; 2) LAA will provide a standardized […]
