IrDA codec board 🔧📡🕰️

We've been designing all sorts of IR transmitters and receivers for the Adafruit shop lately, and a chance discussion got us thinking about IrDA - an old wireless protocol used in some PDAs, watches, laptops and toys. its not used anymore - bluetooth LE does a way better job - but there's probably some cases where IrDA hacking could be useful such as communicating with retro devices or if you want an RF-less wireless link. here's a board that combines a TFBS4711 transceiver (https://www.digikey.com/short/jn43cz31) with a MCP2112 codec (https://www.digikey.com/short/m8tp3708). you can communicate at 115.2kbps with RX and TX lines just like any UART. 115.2kbps is the standard baudrate. or, provide your own CLK for something like 9600 baud.

“Americans, your calls and texts can be monitored by Chinese spies,” a Washington Post opinion piece recently headlined. China has “growing cyber-sophistication and relentless ambition to undermine U.S. infrastructure” another Post article reported. Some analyses trace the recent exploitation to a telecommunications network backdoor created early in the era of digital networks to allow for court-authorized wiretaps.

When the digital wiretap law was passed in 1994, no one foresaw the kind of sophisticated intrusions apparently developed by the Chinese. It is an experience that we must remember as the design of digital network technology continues to evolve. 

I helped negotiate the 1994 Communications Assistance for Law Enforcement Act (CALEA) that, some fear, created the exploitable access for Chinese spies. The concern at the time was that the evolution from analog to digital telecommunications was hindering law enforcement. “Some of the problems encountered by law enforcement relate to the explosive growth of cellular and other wireless services,” the House committee report explained. “[T]he increasing amount of transactional data generated by the millions of users of on-line services” was an accompanying problem. Written 30 years ago, it is a description of today’s communications environment, in which wireless networks deliver online digital information.

At the time, I was the CEO of the Cellular Telecommunications and Internet Association (CTIA), the wireless industry’s trade association. Along with wired communications providers, our members were concerned about the way the FBI was proposing to monitor communications across the new digital technology. After detailed and lengthy negotiations, industry and law enforcement mutually agreed to a result that addressed the FBI’s concerns about access to the new technology, while also addressing industry concerns.

On August 11, 1994, I sat next to FBI Director Louis Freeh before a joint House and Senate hearing to announce that we had reached an agreement on the CALEA legislation and to urge its passage. That what we jointly endorsed that day could, decades later, be potentially hackable by Chinese spies was not part of that discussion.

Today—30 years after CALEA—a new digital wireless technology promoted by both the industry and government is raising new cyber risks. Called Open Radio Access Network (O-RAN), it is a new technical standard that seeks to copy for telecommunications infrastructure the scale and savings enjoyed by the computer industry’s interoperability of different pieces of network equipment from different vendors. In O-RAN, the network functions once performed by purpose-built hardware are instead virtualized in software. Based on input from the Federal Communications Commission (FCC) and Department of Commerce, the software is broken into multiple layers, thus expanding the number of vendors.

The O-RAN concept is an important step forward that will deliver increased capabilities at decreased costs. Accompanying these advantages, however, is the challenge to mitigate the increased risk of cyberattacks resulting from software that relies in part on open-source code running on commodity hardware. 

Earlier networks ran on proprietary equipment utilizing proprietary software that offered focused protection against attacks. Moving more functions to hackable software that is disaggregated from a purpose-built network appliance creates new pathways to attack these new networks.

Another attractive aspect of O-RAN is how the shift to virtualize hardware breaks the chokehold of the traditional suppliers of network equipment. This advantages cybersecurity because it creates alternatives to Chinese hardware manufacturers, such as Huawei. Yet, this too comes with the countervailing paradox that such supplier diversity represents another increase in the number of attack trajectories in the networks.  

As the European Union’s Report on the Cybersecurity of Open Radio Access Networks concluded, while there are security benefits to the diversification of suppliers, “by introducing a new approach, new interfaces and new types of RAN components potentially coming from multiple suppliers, Open RAN would exacerbate a number of the security risks of 5G networks and expand the attack surface.”

Network operators and law enforcement were reportedly blindsided by the ability of Chinese hackers to create advanced persistent threats (APTs) to exploit CALEA. This experience, however, is but the most current of many warnings that the networks on which our nation relies are vulnerable. Whatever the outcome of the ongoing investigation, the latest exploitation should send a message that we need cybersecurity as a forethought, rather than an afterthought, in the design of digital networks, accompanied by ongoing oversight of network security.

Looking back to go forward

Twenty years after CALEA passed, I was chairman of the FCC, the agency responsible for America’s networks. As chairman, I tried to work with network providers to develop cybersecurity standards that were flexible enough to evolve with the technology and the ever-evolving attack techniques of those seeking to exploit the networks. The irrefutable fact is that every single one of the cyberattacks that affect our nation traverse, at one point or another in their transmission, a private network regulated by the FCC.

What we proposed in 2014 was that the companies implement and report on their adherence to the National Institute of Standards and Technology’s (NIST) Cybersecurity Framework. The NIST Framework is a collection of best-practice internal controls developed collaboratively with industry that is continually evolving to help companies protect against cyberattacks. Along with implementing the voluntary NIST Framework, we asked the industry to identify where they set their objective cyber-risk threshold, their progress toward implementation of the Framework, and the steps taken to cure internal control shortfalls.

It was a new approach to network oversight that stopped short of regulatory micromanagement in favor of standards-based expectations. “The communications sector is at a critical juncture,” I said in a June 14, 2014, speech laying out the new program. “We know those [cyber] threats are growing. And we have agreed that industry-based solutions are the right approach… We will implement this approach and measure results. It is those results that will tell us what, if any, next steps must be taken.”

Unfortunately, the effort fell apart when the companies resisted a plan for reporting to the FCC. The industry argued the Department of Homeland Security (DHS) was a better place for such oversight. DHS, of course, had no regulatory authority over the networks. The Trump FCC then followed the industry’s preference and ceased the FCC initiative. 

DHS subsequently established the Cybersecurity and Infrastructure Security Agency (CISA), which is doing great work to advance best practices across the economy. Absent regulatory authority, however, such efforts can only go so far.  Cyber risk is a business risk; at the end of the day, how much a company invests in risk reduction is a bottom-line decision. The appropriate role for a regulator such as the FCC should be to establish expectations for such decisions to stimulate sufficient cyber protection by the nation’s networks—and then to inspect the results.

Today, the FCC’s minimal cybersecurity reporting obligations are constrained to cyber incidents that lead to outages, with no reporting requirements for compromises to confidentiality or network integrity. Amazingly, through its detailed reporting requirements on cyber issues, the Securities and Exchange Commission (SEC) has more information on cyber shortfalls than the regulator charged with protecting America’s networks. 

Thirty years ago, government and industry worked together to protect public safety and national security in a rapidly evolving digital environment. Ten years ago, industry and government could not come to terms with ongoing cybersecurity oversight at the FCC. The current cyberattacks are a clarion call that network security must be both a forethought in network design and an ongoing regulatory responsibility for the agency entrusted with oversight of the nation’s networks.

[what-is-mobile]

WHAT IS MOBILE ?

A mobile phone, or cell phone,[a] is a portable telephone that allows users to make and receive calls over a radio frequency link while moving within a designated telephone service area, unlike fixed-location phones (landline phones). This radio frequency link connects to the switching systems of a mobile phone operator, providing access to the public switched telephone network (PSTN). Modern mobile telephony relies on a cellular network architecture, which is why mobile phones are often referred to as 'cell phones' in North America.

Mobile phones also support a variety of multimedia capabilities, such as digital photography, video recording, and gaming. In addition, they enable multimedia playback and streaming, including video content, as well as radio and television streaming. Furthermore, mobile phones offer satellite-based service

The first handheld mobile phone was demonstrated by Martin Cooper of Motorola in New Y

Mobile phones are considered an important human invention as they have been one of the most widely used and sold pieces of consumer technology.[7] The growth in popularity has been rapid in some places, for example, in the UK, the total number of mobile phones overtook the number of houses in 1999.[8] Today, mobile phones are globally ubiquitous,[9] and in almost half the world's countries, over 90% of the population owns at least one.[10]

History

Main article: History of mobile phonesMartin Cooper of Motorola, shown here in a 2007 reenactment, made the first publicized handheld mobile phone call on a prototype DynaTAC model on 3 April 1973.In 2001, the third-generation (3G) was launched in Japan by NTT DoCoMo on the WCDMA standard.[15] This was followed by 3.5G or 3G+ enhancements based on the high-speed packet access (HSPA) family, allowing UMTS networks to have higher data transfer speeds and capacity. 3G is able to provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. This ensures it can be applied to mobile Internet access, VoIP, video calls, and sending large e-mail messages, as well as watching videos, typically in standard-definition quality.

By 2009, it had become clear that, at some point, 3G networks would be overwhelmed by the growth of bandwidth-intensive applications, such as streaming media.[16] Consequently, the industry began looking to data-optimized fourth-generation (4G) technologies, with the promise of speed improvements up to tenfold over existing 3G technologies. The first publicly available LTE service was launched in Scandinavia by TeliaSonera in 2009. In the 2010s, 4G technology has found diverse applications across various sectors, showcasing its versatility in delivering high-speed wireless communication, such as mobile broadband, the internet of things (IoT), fixed wireless access, and multimedia streaming (including music, video, radio, and television).

Best Partner for Wireless Modules: A Comprehensive Antenna Selection Guide

n the field of wireless communication, antenna selection is crucial. It not only affects the coverage range and transmission quality of signals but also directly relates to the overall performance of the system. Among various wireless modules, finding the right antenna can maximize their potential, ensuring stable and efficient data transmission.

When designing wireless transceiver devices for RF systems, antenna design and selection are essential components. A high-quality antenna system can ensure optimal communication distances. Typically, the size of antennas of the same type is proportional to the wavelength of the RF signal; as signal strength increases, the number of required antennas also grows.

Antennae can be categorized as internal or external based on their installation location. Internal antennas are installed within the device, while external antennas are mounted outside.

In situations where space is limited or there are multiple frequency bands, antenna design becomes more complex. External antennas are usually standard products, allowing users to simply select the required frequency band without needing additional tuning, making them convenient and easy to use.

What are the main types of antennas?

External Antennas: These antennas can be classified into omnidirectional antennas and directional antennas based on the radiation pattern.

Internal Antennas: These antennas refer  to antennas that can be placed inside devices.

Omnidirectional Antennas: These antennas radiate signals uniformly in the horizontal plane, making them suitable for applications that require 360-degree coverage, such as home Wi-Fi routers and mobile devices.

Directional Antennas: These antennas have a high emission and reception strength in one or more specific directions, while the strength is minimal or zero in others. Directional antennas are primarily used to enhance signal strength and improve interference resistance.

PCB Antennas: These antennas are directly printed on the circuit board and are suitable for devices with limited space, commonly used in small wireless modules and IoT devices.

FPC Antennas: FPC antennas are flexible printed circuit antennas that are lightweight, efficient, and easy to integrate.

Concealed Antennas: Designed for aesthetic purposes, concealed antennas can be hidden within devices or disguised as other objects, making them suitable for applications where appearance is important without compromising signal quality.

Antenna Selection Guide

When selecting the appropriate antenna for a communication module, it's essential to first determine whether to use an internal or external antenna based on the module's structure.

External Antennas: These antennas offer high gain, are less affected by the environment, and can save development time, but they may take up space and impact the product's aesthetics.

Internal Antennas: These have relatively high gain and are installed within the device, maintaining a clean and appealing exterior.

 Sucker  Antennas: These provide high gain and are easy to install and secure.

Copper Rod  Sucker  Antennas: Made from large-diameter pure copper radiators, these are highly efficient with a wide bandwidth.

Rubber Rod Antennas: Offer moderate gain at a low cost.

Fiberglass Antennas: Suitable for harsh environments and ideal for long-distance signal

External Directional Antennas

Typically used in environments with long communication distances, small signal coverage areas, and high target density.

Panel Antennas have high efficiency, are compact, and easy to install, while considering the impact of gain and radiation area Yagi Antennas offer very high gain, are slightly larger, and have strong directionality, making them suitable for long-distance signal transmission; however, attention must be paid to the antenna's orientation during use

Internal Antenna Selection

Most internal antennas are affected by environmental factors and may require custom design or impedance matching

Spring Antennas are cost-effective but have low gain and narrow bandwidth, often requiring tuning for good matching when installed Ceramic Patch Antennas occupy minimal space and perform well, but have a narrow bandwidth

Character Intro: Ascalaphus (Kingdom of Ichor)

Nicknames- My boy by Acheron

Darling by Orphne

Age- 17 (immortal)

Location- The Underworld

Personality- He's a broody yet eccentric young god who loves intellectual pursuits, gothic aesthetics, & a deep appreciation for classic literature and art. He's currently single.

He has the standard abilities of a god. His other powers/abilities include limited chlorokinesis (as it pertains to plants & flowers native to the Underworld), limited necromancy, being able to communicate with/shapeshift into a screech owl, limited umbrakinesis (shadow manipulation), and limited hydrokinesis (as it pertains to the waters of his father's river).

Ascalaphus is the only child of his parents- Acheron (Titan god of pain) & Orphne, a lampade.

He lives with his parents at their mansion in the Underworld. Ascalaphus' room is on the third floor. The bedroom door is built out of blackwood & there's also a terrace where he can overlook his father's river. The flooring is black marble while the walls are brimstone- covered in posters of his favorite bands, singers, movies, and deities. Instead of a laptop, there's an antique typewriter. In his room there's a simple trundle bed covered in dark blue satin pillows & black quilts, white onyx shelves for his book collection, as well as his blue-black iCHOR Tech wireless speaker that's automatically connected to Musify.

Ascalaphus is his father's twin with their olive skin, brown-black eyes, and facial features with the only difference being their frames. Acheron has a lean muscular build while his son has a bit more muscle. He feels like his mother feels left out because she doesn't look like them with her brilliant dark blue eyes, dark obsidian skin, and thick curly hair.

He's fluent in Latin.

He keeps his ink black hair short & shaggy.

Ascalaphus has a few tattoos- large owl wings on his back, a pair of dark blue eyes (dedicated to his mom) on the inside of his left wrist, a skull surrounded by black dahlias on his right arm, and the quote "What nourishes me destroys me" written in latin on his left pec. His good friend Achlys (goddess of the death mist, poison, misery, & sadness) did the tattoos.

A go-to drink for him is beer. He also likes red wine, pomegranate brandy, his dad's jallab, his mom's homemade blackberry iced tea, ginger ale, hot chocolate, black tea, mineral water, and cola.

Ascalaphus primarily writes in cursive.

For breakfast he'll typically go to a corner store to get a sausage, egg, & cheese on a hero on toasted rye bread. If he's gonna be on time for school, he'll have a bowl of steel cut oats topped with dark chocolate chips and maple syrup, a bowl of Earthly Harvest raisin crunch cereal, or his mom's omelette- added with black olives, mushrooms, & ghost peppers.

Ascalaphus loves listening to classical, synth pop, folk, rock, heavy metal, rap, and death metal music. His favorite musical artists to listen to are Moros (god of doom), O, & the death metal rap band Death Theater- comprising of Hades, Charon (Ferryman of the Underworld), his friend Hypnos (god of sleep), and Thanatos (god of death). He also thinks that Pale Blu isn't too bad either.

He's currently a freshman at Polydegmon University, the most prestigious college in the Underworld. Ascalaphus has a full ride- a four year scholarship, thanks in part to his father as well as the king. He doesn't live on campus, an agreed compromise with his parents. Even though it's too early to declare a major, Ascalaphus is thinking about majoring in botany or art history.

Thus far his favorite class has been his gothic literature class taught by his professor- a lampade named Ms. Whiteveil. The sound of her velvet smooth voice while she reads poems and short passages automatically calms him.

He loves snacking on ash plum flavored gummy spiders. He also likes spicy mushroom flavored kettle cooked potato chips & black anise licorice twists.

Ascalaphus has a job of sorts. He tends to the garden of the king of the Underworld, Hades (god of the dead). The orchard is primarily filled with black dahlias, frost orchids, black thorned roses, and shadow blossoms. He actually likes working in the garden. It's one of the few moments where Ascalaphus is alone with his thoughts for self-reflection. He also doesn't mind the company of the king. Hades will bring him a small cup of dark roast coffee or will lend Ascalaphus a book from his extensive library.

He also earns extra money by picking up groceries for Geras (god of old age) & by dog-sitting Cerberus sometimes.

There's a small restaurant downtown in Plouton Square that makes the best jjajangmyeon (noodles & diced pork in black bean sauce). It's a frequent takeout order for him.

All though Ascalaphus loves his parents, he feels like they're keeping him on a tight leash, especially his father. They didn't even want him to live on campus in a dorm and they especially don't want him to leave or travel out of the Underworld to any of the other realms- Olympius in particular. The Realm of Darkness is all he ever knows and Ascalaphus just wants the chance to experience something new, something different.

At school his social circle consists of cyclopes named Osric, Sybil, & Quintessa (Tessa for short), a harpy named Xerxes, a lampade named Azura (a botany major), as well as mortals named Caspian (a art history major), Rosalind, and Venetia.

Ascalaphus in undecided about whether or not to join the University's fraternity. Osric is a member.

Outside of school he's real good friends with Theodon (god of reality, uncertainty, & fate). They hang out together all the time. They smoke weed sometimes (through use of a Stygian Iron bong) & Ascalaphus will invite Theo to play basketball with him, Osric, Xerxes, and Caspian every weekend at Shadowstone Park. Theodon even tagged along to Ascalaphus' first college party!

He really liked going to the film premier of Blooddancer with Theodon. Ascalaphus even got to briefly meet the director of the film Keres (goddess of violent death). The photo of them meeting is framed & on his dresser. He also saved the ticket stubs!

In the pantheon he's also friends with Despoina (goddess of the arcadian mysteries, frost, winter, & shadows).

Also in the pantheon Ascalaphus respects and admires Nyx (goddess of the night) Erebus (god of darkness), as well as his "honorary" aunts & uncles, the other Underworld river deities- Phlegethon (Titan god of fire), Lethe (Titaness of forgetfulness, oblivion, & concealment), Styx (Titaness of hatred), and his godfather Cocytus (Titan god of wailing & lamentation).

He also admires Favian (god of philosophy) & is a fan of his steampunk historical fantasy book series The Machinery of Alchemists.

The iCHOR Tech soundproof headphones are great when Ascalaphus is working on an assignment or blocking out the sounds of his parents' lovemaking.

Sometimes (without his parents knowing), Ascalaphus will travel out-of-realm to Olympius to pick up Theodon from school. He pretends not to care as Theo drones on and on about a fellow schoolmate Heimarmene (Marnie) (goddess of shared fate). One day while Ascalaphus was waiting for Theo where he noticed him walking down the school's steps with Marnie and another girl. He thought she looked like winter's light with her flawless pale skin and shimmery silver eyeshadow on her eyelids. Her smile was just as bright as she tucked away strands of her short bouncy golden light brown hair behind her hair. When Ascalaphus asked Theo about her when he got in the car, he said that she was Marnie's best friend Eiresione (Ren) (goddess of offerings).

His favorite frozen treat is dark chocolate ice cream topped with pomegranate syrup, dark chocolate chips, and whipped cream.

Aside from wanting to freely travel to Olympius, Ascalaphus also wants to check out the Electric Wonderland music festival after looking it up online.

His favorite dessert is his mom's black rum cake. She makes it every year for his birthday and on the Winter Solstice.

Ascalaphus is not ashamed about the fact that he's still a virgin. He wants to wait until he's emotionally connected with someone to have sex. He did make out with an empousa named Elidi at the college party.

His all time favorite meal is his dad's hearty lamb stew with saffron rice and his mom's scorched chicken.

In his free time Ascalaphus enjoys playing video games, reading, skateboarding, writing, snowboarding, gardening, skiing, ice hockey, cooking (with his parents), ink painting, going to museums, chess, listening to music, and going to the cinema. He's also been getting into photography.

"Owls inspire us to see beyond the darkness and find our own light."

Another thing i was thinking about is androids having to work with other androids. We got an idea of how androids usually interacts with other androids, at least in Shades of Color. But what if we got an android team with a human commander and these androids need to work together and help each other without the human having to give every single order like "help the other plastic"?

I hope it's a thing even if they got different tasks in the moment. Doesn't needa be a chat or talking loud, wireless communication is a communication.

Be in mind i ain't talking about deviant androids. I'm talking, for example, construction workers. What if they got a task that needs 2 or more androids cooperating and we ain't got a human in there? That's what i'm talking about. Cooperation among androids to finish a task given should be standard procedure depending on 'em work.

[mostlysignssomeportents]

This day in history

On September 22, I'm (virtually) presenting at the DIG Festival in Modena, Italy. That night, I'll be in person at LA's Book Soup for the launch of Justin C Key's "The World Wasn’t Ready for You." On September 27, I'll be at Chevalier's Books in Los Angeles with Brian Merchant for a joint launch for my new book The Internet Con and his new book, Blood in the Machine.
