VoIP: Beyond Digital POTS

I've been involved with VoIP technology since 1996. I've been a public advocate for wideband audio at least since 1997. And I've admired and supported a variety of companies using VoIP to provide innovative services and new user interfaces. But reflecting on the past decade, the only globally significant impact of VoIP has been on prices (by fostering arbitrage). Most VoIP telephony services are just digital POTS... more

Frustrations with VoIP Phone Services

I ought to explain why I've suddenly gone cold on VoIP. It's just I've watched my own behaviour. I've grown tired of the inconsistency of PC VoIP calls, and instead I've reverted to using landlines, mobiles and Jajah (for callback). But I'm still using IM to set up many of those calls! The problem isn't unique to any one client - they're all proving unsuitable for business use with clients (which is most of my telephony needs covered). The worst of all seems to be Skype conference calling... more

.Mobi Premium Name Auction Off to Wild Success at TRAFFIC in Miami

I'm in attendance at the the TRAFFIC EAST 2006 show, in Hollywood [Miami], Florida. There has been a lot of buzz here about the .Mobi top level domain, ranging from the talk of early registrants hoping to create the next big mobile portal to those that were keen to see implementations of mobile content. There was a domain name auction this evening where flowers.mobi sold for $200,000.00 (USD), and fun.mobi for $100,000.00 (USD) from a long list of domain names in the com, net, info, org, us and mobi extensions. more

ENUM: Mapping the E.164 Number Space into the DNS

Many communications networks are constructed for a single form of communication, and are ill suited to being used for any other form. Although the Internet is also a specialized network in terms of supporting digital communications, its relatively unique flexibility lies in its ability to digitally encode a very diverse set of communications formats, and then support their interaction over the Internet. In this way many communications networks can be mapped into an Internet application and in so doing become just another distributed application overlayed on the Internet. From this admittedly Internet-centric perspective, voice is just another Internet application. And for the growing population of Voice over IP (VoIP) users, this is indeed the case... more

Telecom Impact on Per-Capita GDP

My presentation at VON was focused on availability (aka presence) and contextually-aware communications, but I did begin with a brief mention of subjects I'm passionate about and I ended with my typical closing comments about telecommunications... Apparently this struck a chord with several people who came up to me afterwards asking about how they could help the spread of telecom to developing countries and did I have references for my statements about telecom is good for mankind? more

Examining the Reality of Convergence

If there is one word in the telecommunications that has suffered from over-abuse for many years now, it's convergence. The term has been liberally applied to each successive generation of communications technology for their supposed ability to solve a myriad of service delivery problems within a single unifying converged carriage and service delivery solution. Unfortunately, the underlying reality has always been markedly different from these wondrous promises, and we continue to see an industry that deploys a plethora of service delivery platforms and an equally diverse collection of associated switching and service delivery technologies. One can't help but wonder at the collective gullibility of an industry that continues to herald the convergent attributes of each new generation of communications technology, while at the same time being forced to admit that previous convergent promises have never been realized. more

London Ranks Last Among 18 European Capitals for Mobile Download Speeds

Ookla's latest benchmarking ranks London last among 18 European capitals for mobile download speeds, revealing persistent congestion, worsening latency and infrastructure constraints despite widespread 5G availability. more

SpaceX Agrees to Acquire Nationwide 800 MHz Spectrum for Starlink Mobile

SpaceX has agreed to acquire nationwide 800 MHz spectrum licenses from Grain Management in a deal reportedly worth $8 billion, potentially expanding Starlink Mobile's ability to integrate satellite and terrestrial connectivity. more

The Growth of Mobile-Dependent Households

Purdue researcher Roberto Gallardo finds that as US Internet access expanded, millions of households became mobile-dependent, highlighting persistent affordability, device and digital literacy barriers that infrastructure investment alone may not solve. more

AT&T Chief Challenges Economics of SpaceX’s Mobile-Network Strategy

AT&T CEO John Stankey questions the economics of SpaceX's expanding mobile strategy as regulatory filings and independent measurements show the spectrum, satellite capacity and terrestrial infrastructure involved in scaling direct-to-device service. more

4iG and SpaceX Plan Starlink Mobile Rollout Across Hungary and Western Balkans

4iG and SpaceX plan direct-to-device Starlink services across four European markets, alongside secured government communications, but national spectrum approvals and key details of the proposed sovereign infrastructure remain unresolved. more

Starlink’s Unconventional Approach to Cellular

SpaceX is considering a terrestrial cellular network powered by Starlink satellite backhaul, but scarce spectrum, enormous capacity demands and entrenched rivals could make its boldest telecommunications gambit yet far harder to execute profitably at scale. more

Is Satellite Cellular a Competitive Threat?

Direct-to-device satellite cellular promises to extend coverage beyond terrestrial networks, but physics, capacity constraints, and indoor limitations suggest it will complement existing mobile service rather than emerge as a true competitor. more

Amazon Targets Satellite-to-Phone Market With 5,105-Satellite Leo Expansion

Amazon has outlined plans for a 5,105-satellite constellation that will connect smartphones directly from space, expanding emergency and mobile services while intensifying competition in the fast-growing satellite-to-device communications market. more

Why Are We Building 6G?

As 6G development accelerates, its promises of faster speeds, lower latency, and immersive applications raise questions about whether carriers can justify another costly network upgrade when 5G's commercial promises remain largely unfulfilled across the industry. more
