iPhone 4 Highlights Mobile Problems

Making a telephone call in London has become more difficult for early adopters of the new iPhone 4. First of all the reception is rather poor. And it is not just that it is not showing the bars correctly; many users in congested mobile areas such as London receive the message 'server not available'. (As a matter of fact, this doesn't apply only to the iPhone -- it is also experienced with other smart phones.) more

Wireless Broadband vs Fixed Broadband - The Story Continues

This never-ending story is used by opportunistic telcos and their lobbyists to confuse the issue in order to gain regulatory or political advantage. The debate is now raging again in the USA. In an attempt to talk down their monopolistic position in the market the three telcos - and this time in particular, Comcast - are claiming that real competition does in fact exist in the American broadband market, citing competition from the mobile 4G LTE services as an example. more

Ten SpaceX Starlink Updates

Starlink now has nearly 500,000 users and is available in 32 countries and nine languages. It is either available, wait-listed, or coming soon in every nation except Afghanistan, Belarus, Cuba, China, Iran, North Korea, Russia, Syria, and Venezuela. There are now 15,000 Starlink terminals in Ukraine with service throughout the nation through connections to ground stations in Poland, Lithuania, and Turkey and they have made a significant contribution in the war with Russia. more

The Defense Department Opening Large Areas of Mid-Band Spectrum to Help US Compete With China in 5G

On Monday, the Trump administration announced plans to auction off 100 megahertz of mid-band spectrum dedicated initially to military purposes for commercial use starting in mid-2022 to fuel 5G network deployment in the United States. more

Bandwidth: Why Fast is Important in a Global Economy

Bandwidth is the basic foundation for Internet traffic as a connector to everything important in our lives. Whether it is basic bandwidth for connecting to family and friends, or a super fast highway for global reach and competitiveness in the business world, bandwidth constitutes the speed at which we connect as a global presence within the expanding sphere of Internet communication. ... To understand why bandwidth is important to all Americans, including personal and business uses, we must understand the different types Internet traffic. more

LTE and Spectrum Stupidity

Mobile operators are counting on Long Term Evolution (LTE) technology to handle surging demand for mobile data access. But LTE developers made some poor choices, cutting spectral efficiency and thus driving up operator costs. LTE was envisioned as an all IP system, but the RF allocations follow the voice-centric approach of earlier generations. While LTE standards allow for either Frequency Division Duplexing (FDD) or Time Division Duplexing (TDD), all initial LTE equipment uses FDD. FDD requires two separate blocks of spectrum... more

Hongyun Project – China’s Low-Earth Orbit Broadband Internet Project

Last December, State-owned China Aerospace Science and Industry Corporation (CASIC) launched the first experimental Hongyun (rainbow cloud) Project satellite, and they began testing it in March. The 247 kg test satellite is in orbit at an altitude of around 1,100 km, and they plan to launch four more test satellites this year and begin operating with a 156-satellite constellation in 2022. more

$400B China-Iran Deal Includes a $Billion 4G-5G Network, Most Likely Huawei

China has agreed to buy $16 billion/year of Iranian oil in what amounts to a barter arrangement for Chinese goods. Telecommunications is specifically included, with a $billion or more for an upgraded mobile system. Huawei & ZTE will probably split the contract. Iran's population is 84 million, about the same as Germany or Turkey. That's as much as Ireland, Norway, Finland, Denmark, Switzerland, Austria, Sweden, Belgium, and the Netherlands combined. Nothing's announced, but it will be a big deal. more

Lessons from the O2 Network Outage: The Real Cost of Manual Processes

More than 30 million people lost their data connectivity on December 6, 2018, in the United Kingdom as O2's network suffered from a nationwide service outage. Based on several reports, the incident was caused by a human error at Ericsson, the telecoms supplier responsible for operating certain parts of the O2 network. To compensate for the downtime and tarnished reputation, the O2 management is now reportedly seeking damages of up to a hundred million pounds from Ericsson. more

The Internet and the Cloud Are Going Into Space

Unlike Bezos and Branson, they're going to stay there. Today we have space-based internet access and a terrestrial internet; within ten years, we'll have a space-based internet. Internet traffic will travel more miles in space than on terrestrial fiber. By that time, the great cloud data centers of Google, Amazon, Microsoft, and their competitors and successors will mostly be in orbit as well. Five years from now, this transition will be obvious, accepted, and well underway... more

Emerging Communications Technologies

A "New IP" framework was proposed to the ITU last year. This framework envisages a resurgence of a network-centric view of communications architectures where network-managed control mechanisms moderate application behaviors. It's not the first time that we've seen proposals to rethink the underlying architecture of the Internet's technology (for example, there were the "Clean Slate" efforts in the US research community a decade or so ago) and it certainly won't be the last. more

Huawei’s Very Red World

The map below shows countries working with Huawei 5G in red and pink. As can be seen, Huawei is doing very well in 5G, although it's not as dominant as the colors here suggest. Ericsson is actually close to Huawei in 5G revenue, aided by the ban in the US and Australia. Years ago, Huawei was the price leader in order to break into the European market. more

Absolutely No Wireless Spectrum Shortage in 2010

Sure the iPhone has problems, but John Stankey of AT&T thinks restoring a $2B capex cut will fix them. It may take a little more money than that, but Glen Campbell of Merrill Lynch has confirmed he's on track. In a 50 page report that's one of the best I've read in years, Merrill destroyed the common belief that wireless has a significant spectrum shortage. more

The Satellite Broadband is Heating Up

There is a lot of news recently about low-orbit satellite broadband. There is recent news concerning the three primary companies that will be vying in the space. First is Jeff Bezos Project Kuiper, which is still likely to get a brand name at some point. Project Kuiper has contracted with United Launch Alliance, a joint Boeing-Lockheed Martin venture, for the first nine broadband rocket launches. more

Network Neutrality in the Wireless Space

There's been a tremendous amount written about the Google-Verizon joint proposal for network neutrality regulation. Our commentary at the EFF offers some legal analysis of the good and bad in this proposal. A lot of commentary has put a big focus on the exemption for wireless networks, since many feel wireless is the real "where it's gonna be," if not the "where it's at" for the internet. more
