Update on China SatNet’s GuoWang Broadband Constellation – Can They Do It?

In 2020, China applied to operate GuoWang, a constellation of 12,992 low-Earth orbit (LEO) broadband Internet satellites, and in 2021, it became clear that it was intended to become China’s global LEO broadband constellation. Can they do it? Maybe, but it will take a long time. China does not have the capacity to launch 12,992 satellites today. I don’t know the mass of their planned satellites, but GuoWang is informally referred to as China’s answer to Starlink. 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

SIP Co-Author Henning Schulzrinne Appointed CTO of the FCC

In a move to be celebrated by many of us with a VoIP background, the United States Federal Communications Commission (FCC) announced today the appointment of Henning Schulzrinne as Chief Technology Officer (CTO). As the release indicates, Henning's role as CTO will be to: ...guide the FCC's work on technology and engineering issues, together with the FCC's Office of Engineering and Technology. more

Low-Earth Orbit (LEO) Satellite Internet Service Developments for 2019

I posted reviews of important LEO-satellite Internet service developments during 2017 and 2018. I've been updating those posts during the years and have 16 new posts for 2019. In 2019 we saw four inciteful simulations, Leosat suspending operations and Amazon announcing the availability of a new ground station service and plans for a LEO constellation, progress in phased-array antennas but a lowering of expectations for inter-satellite laser links (ISLLs), new competition from China... more

NSA Takes a Leadership Seat at the Global 5G Security Table

It has been a long time coming. In the world of global 5G security, there is only one principal forum. The somewhat cryptically named 3GPP SA3 is dedicated to 5G security and holding its 103rd meeting electronically next week from 17 to 28 May with 772 submitted documents and 189 participants registered. SA3 meets every 60 days and exists at the security center of an ecosystem of numerous technical groups encompassing many hundreds of companies, industry organizations, and government agencies worldwide. 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

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

The New Clearwire

The new Clearwire could be game-changing, but the rules of the game may not be quite as Clearwire presents them. I have been wondering since last July whether something significant would happen in the Google/Sprint world. The deal announcement earlier this weekseems to be that key development... In a nutshell, Sprint will contribute its substantial spectrum licenses in the 2.5 GHz range and its WiMAX-related assets and intellectual property. Google, Intel, Comcast, Time Warner Cable, and Bright House Networks will invest a total of $3.2 billion. more

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

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

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

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

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
