Is 5G Radiation Safe?

There is a lot of public sentiment against placing small cell sites on residential streets. There is a particular fear of broadcasting higher millimeter wave frequencies near to homes since these frequencies have never been in widespread use before. In the public's mind, higher frequencies mean a greater danger of health problems related to exposure to radiofrequency emissions. more

SpaceX Launching Two Experimental Internet Satellites This Weekend

On Saturday, SpaceX will be launching two experimental mini-satellites that will pave the path for the first batch of what is planned to be a 4,000-satellite constellation providing low-cost internet around the earth. more

Beyond White Spaces

Back in 1999 I wrote a column that envisioned the uses of digital wireless in the home. I compared two nascent, much-touted wireless protocols, Bluetooth and HomeRF. I completely, totally, slippery-dash missed Wi-Fi. There had been a public 802.11 spec since 1997. The first 802.11b devices, which made Wi-Fi popular, burst onto the scene in early 2000, just a few short months after my clueless insights. Today HomeRF is forgotten, Bluetooth is for ugly ear jewelry and Wi-Fi rulz... more

Experts Propose Plan for More Secure Wi-Fi Devices

Over 260 global network and security experts have collectively responded to the newly proposed FCC rules laid out in ET Docket No. 15-170 for RF Devices such as Wi-Fi routers by proposing a new approach to improve the security of these devices. The letter warns FCC ruling will cause more harm than good and risk a significant overreach of the Commission's authority. more

Economics and Common Sense Deprecates the Common Argument for Lower Spectrum Prices

Outside of China, very few governments would expect a saving in spectrum costs would mostly go to investment. Corporations have other priorities, including advertising and executive salaries. Stockholders come above everything at most companies. Rarely would even 1/3rd of the saving go to capital spending. The U.S. under Trump had a massive tax cut, worth literally billions to Verizon and AT&T. Verizon actually cut investment. AT&T's increase in capex was far lower than the tax saving. 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

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

Will Electronically Steered Antennas Replace Parabolic Antennas in Satellite Ground Stations?

Three recent developments make me wonder whether we are on the cusp of a shift in satellite ground station technology from parabolic to electronically steered antennas (ESAs). The U.S. Space Force operates the Satellite Control Network, with 19 parabolic antennas at seven locations around the world. more

Hassle Over LEOs

Every second, 4.5 billion people using computers and other electronic devices send 100,000 gigabytes of information to each other. Around 60% of the world's population has an Internet connection. North America and Europe have penetrations of 95% and 87%. But Asia and Africa do not yet get beyond 54% and 40%. On those continents, there are many remote areas where there is no Internet yet. At least no affordable Internet. more

Some Observations on Reachability of Egyptian Networks and Providers

Different media are reporting that Internet and other forms of electronic communications are being disrupted in Egypt. Presumably after a government order in response to the protests. Looking at BGP data we can confirm that according to our analysis 88% of the ‘Egyptian Internet’ has fallen of the Internet. In this post I’ll share some observations I made with regards to the reachability of Egyptian networks and providers. more

USA: Court Leaves FCC With Discretion to Regulate Special Access Circuits

On Friday, the decision to deregulate "special access" circuits was upheld. The case had been brought by the Ad Hoc Committee, a long standing body of large business users, one of the main categories of buyers of high capacity leased lines to interconnect business premises. more

A Winning Biden 5G Strategy: Flatten the Curve

No, not the COVID curve - the curve of U.S. engagement in global industry 5G activities. Let me explain. What is known as 5G actually consists of a broad array of fundamentally revolutionary virtualization platforms that are constantly, collectively developed by industry in several dozen open global bodies. These bodies meet every few weeks, and several score companies around the world process scores to hundreds of input documents to produce many hundreds of effectively mandatory... 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

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

IEEE Approves 802.11bb Standard, Boosting Global Adoption of Light-Based Li-Fi Communications

The Institute of Electrical and Electronics Engineers (IEEE) has announced the inclusion of 802.11bb, a standard for light-based wireless communications. This new standard is seen as a major boon to global Li-Fi companies as it promises to expedite the rollout and acceptance of this innovative data transmission technology. more
