Be Wary of 5G Hardware

We've now entered the period of 5G competition where the wireless carriers are trying to outdo each other in announcing 5G rollouts. If you believe the announcements, you'd think 5G is soon going to be everywhere. Device manufacturers are joining the fray and are advertising devices that can be used with the early carrier 5G products. Buyers beware -- because most of what the cellular companies and the manufacturers are hyping as 5G is not yet 5G. more

Representatives From EU, NATO, USA, Japan, Australia Hold Meeting on 5G Security and Policy Measures

Representatives from over 30 countries including nations from European Union, NATO, United States, Germany, Japan, Israel and Australia participated in the Prague 5G Security Conference this week. more

Trump’s Strange WRC-19 Letter

The 2019 World Radiocommunication Conference (WRC-19) is underway. It is the latest in a continuum of treaty-making gatherings that began in 1903 and is devoted to the now 116-year-old art of globally carving up the radio spectrum among designated uses that is instantiated in the Radio Regulations treaty agreement. Not unexpectedly, the event includes designation of 5G spectrum that flows from the requirements long set in 3GPP and GSMA. more

Lessons from Sandy: Building Networks and Cyber-Infrastructure to Survive Climate Change

Hurricane Sandy has been a badly needed wake up call for the Internet community as to the threat of climate change. Although most people have forgotten, Sandy is the second hurricane to hit New York in as many years with Irene last August and a third tropical depression headed to New York at the time of this writing. Two, supposedly once in a hundred year storms, within such a short time frame should even make the most die-hard denialist that something's afoot. more

Broadband Carrier Quandary: Exploit Bandwidth Scarcity, or Reduce It?

Comcast enhanced the value position of its broadband subscriptions by increasing the monthly data allowance to 1 Terrabyte (1000 Gigabytes). See Comcast Announcement. As an independent, unsponsored researcher, I can say "Thank You Comcast" without adverse consequences and only a bit of irony. This company does much to displease, but an expanded data allowance offers a winning proposition. more

Loon Balloons Restore Internet After a Massive Earthquake Strikes Remote Parts of Peru

On Sunday, when a magnitude 8.0 earthquake struck remote parts of Peru’s Amazon region, at the request of the government of Peru and Telefónica, Alphabet re-directs a group of its Loon balloons to the impacted area to restore Internet access. Within 48 hours, people on the ground had wireless broadband communication, reports Alphabet. more

LunaNet – Developing the Internet for the Moon

The NASA-sponsored Artemis program is the first step in the next era of human exploration. Together with a large number of international government and academic partners as well as businesses -- and based on international standards -- NASA will establish a sustainable presence on the Moon. more

Google Not the Only Company Testing Wireless Access by High-Altitude Balloons

Oceus Networks Inc., a mobile 4G LTE broadband networking provider, recently demonstrated the efficacy of a deployable 4G LTE solution on a high-altitude balloon platform, which can be used to rapidly provide broadband coverage and communications services to first responders within the first 72 hours following an emergency or natural disaster. more

The Future of Satellite Broadband

People ask me a lot about what Starlink means for somebody building a rural broadband network. That set me to contemplate the long-term prospects for LEO satellite broadband. Today, the broadband provided by Starlink is a boon to rural subscribers who have had no alternatives. Hundreds of thousands of prospective customers have gotten onto the Starlink waiting list. It's not hard to understand why when the rural broadband alternatives are extraordinarily slow rural DSL, high orbit satellite broadband, or cellular hotspots. more

Aircell vs. VoIP

Last week American Airlines launched their Aircell wireless Internet access on a limited number of flights. It didn't take long before a few folks tried to make voice and video calls (in violation of Aircell's terms-of-service according to their PR folks), and it didn't take long before someone figured a way around their voice/video blocking efforts. more

SpaceX Succeeds in Launching Its First Full Batch of Starlink Internet Satellites

SpaceX on Thursday successfully launched 60 Starlink satellites with its Falcon 9 rocket from Space Launch Complex 40 at Cape Canaveral Air Force Station, Florida. more

Mobile Broadband Penetration in Asia

The advent of mobile broadband triggered a huge change in broadband access across Asia. Following more than a decade of strong growth in almost all mobile markets in the region, an amazing transition to new generation mobile networks and services took place. By end 2014 there were a total of 1.2 billion mobile subscribers and with annual growth running at over 40% coming into 2015 the numbers were expected to hit 1.7 billion by end-2015. more

Trump Orders Cyberattacks by US Companies

It is supremely ironic. A rogue national leader with the stroke of a pen, dictates that its companies will expose a foreign company's end users to cyberattacks. This is the net effect of denying security patches or operating system updates pursuant to Trump's order. In the US Great Rogue Leader's bizarro world, this is the very behavior that he claims makes his actions necessary. In fact, this Trump malware attack is worse because of the mass exposure to exploits. more

Geely’s LEO Constellation for Mobile Vehicle Connectivity

The Geely Holding Group (GHG) is a private Chinese conglomerate that is highly diversified but best known as an auto manufacturer that envisions itself as a "global mobile technology group." GHG announced this week that it has begun construction of an intelligent satellite production and testing facility that will include modular satellite manufacturing, satellite testing, satellite R&D, and cloud computing centers.

Update Mar 2, 2024:

Geely launched eleven satellites in the same 50-degree inclination plane as the first nine, but there was a considerable delay between the two launches. The first nine were launched in June 2022 and the second 11 were launched in February 2024. The delay may have been caused by a satellite re-design -- The mass of these satellites is 130 kg whereas the first nine satellites had masses of 100 kg.

The launch cadence will have to speed up if they are to reach their goal of beginning service with 72 t satellites next year. more

Australian Farms Get Connected to the Starlink Satellites

Last year, I reported on the possibility that LEO (Low Earth Orbit) satellite-based systems might be a gamechanger for the delivery of high-speed data services, including internet access, to people in regional and remote Australia. What has become clear with the rollout of the NBN is that the quality of data connections in metropolitan cities in many cases has improved, but that the rest of Australia doesn't have a similar experience. more
