As Wi-Fi is deployed more widely in cities, and perhaps at higher frequencies, it may depend on an abundant urban asset: streetlight poles.

To help ensure these networks work well, researchers at the National Institute of Standards and Technology (NIST) have developed and verified a novel model that will help wireless communications providers analyze how high to attach Wi-Fi equipment to light poles.

In general, the NIST team found that the optimal height depends on transmission frequency and antenna design. Attaching equipment at lower heights of around 4 meters is better for traditional wireless systems with omnidirectional antennas, whereas higher locations 6 or 9 meters up are better for the latest systems such as 5G using higher, millimeter-wave frequencies and narrow-beam antennas.

The world’s most advanced four-legged robot finally sees in color.

Over the last couple of years, we’ve continued to make improvements to Spot to better enable our customers. Today we’re adding to the list! https://bit.ly/3y68Ow1

Finally, Spot’s charger is now smarter and faster, bringing Spot’s newest battery models to full capacity in an hour or less. Users can refer to the OLED display for real-time information on battery charge and can continue to charge the robot directly or hot-swap batteries for continuous operation.

I am going another route, and think Lifeboat, and others to may want to think about accounts with Mastodon, and others. We often empower what we don’t like and complain about. How does Mastodon work? Well for starters you can get a dedicated server, you moderate yourself, 🙄…and:

“Mastodon is a social media network comprised of nodes (called ”servers” or ”instances”), each running special software. Anyone can run their own Mastodon instance (if they have the proper dedicated server), which can then link to others in a federation or remain private. Individuals or companies can have complete control over individual Mastodon servers, so there are still centralized points of administration, but it’s not as concentrated as in the case of Twitter, Tumblr, or Facebook.

The Mastodon software is open source. It is based on an open-source social networking protocol called ActivityPub, which is developed by the World Wide Web Consortium (the same organization that maintains standards for the web.)

Lately, there’s been no shortage of talk about the transition to Web3, a new digital frontier powered by blockchain and accessible via decentralized applications (dapps). But while many of the products created thus far are groundbreaking — offering verifiable digital ownership and access to new financial instruments — they still haven’t managed to galvanize mainstream adoption yet.

To reach critical mass, the blockchain industry needs to ensure that platforms and services are easy to use as their current-gen counterparts. ## **We aren’t there yet**

The current landscape of the internet is still very much grounded in Web2 architecture. While users can access a range of services, each requires its own unique username and password and third-party platforms are typically still needed to process payments. While this model has ostensibly worked well enough for the past two decades, it’s been mired by the centralized control of big tech companies, which thrive on selling user data.

SpaceX has successfully launched and landed the same Falcon 9 booster twice in three weeks, smashing the current record for orbital-class rocket turnaround.

The existing record was also held by Falcon 9 and set in early 2021 when booster B1060 launched a Turkish communications satellite and a batch of Starlink spacecraft just 27 days and 4 hours apart. Now, just under 15 months later, a new Falcon 9 booster has decisively taken the crown.

At 5:27 pm EDT, Falcon 9 B1062 lifted off as planned from SpaceX’s Cape Canaveral Space Force Station (CCSFS) Launch Complex 40 pad. Flying for the sixth time, the reused booster carried an expendable Falcon upper stage, fairing, and a batch of 53 Starlink V1.5 satellites most of the way out of Earth’s atmosphere to a velocity of 2.2 kilometers per second (Mach ~6.5) before separating and landing on a SpaceX drone ship.

Musk’s company SpaceX is supplying internet service to troops in Ukraine, and helping them beat the Russians.

When it comes to responding to emerging threats, the Pentagon’s director for electromagnetic warfare suggested today that the US military’s electronic warfare organization should borrow a leaf from SpaceX.

SpaceX founder Elon Musk said that Russia had jammed Starlink terminals in Ukraine for hours at a time after SpaceX shipped Starlink terminals to Ukraine in February in an apparent effort to help Ukraine preserve its internet connection amid the war with Russia. Starlink was back up and running after a software upgrade, according to Musk, who added on March 25 that the constellation had “resisted all hacking & jamming attempts” in Ukraine.
