It's an uncertain waiting game as to when the next-generation high-speed wireless service known as 5G will reach mass market, but the business implications are already a major talking point at CES 2018.

The term "5G" refers to the fifth-generation wireless broadband technology based on the 802.11ac standard. The packet of technology will bring speed and coverage improvements from 4G, with low-latency wireless up to 1GB/s, and it'll spur a host of new opportunities for enterprises and workplace productivity.In a panel discussion at CES, a trio of executives from Qualcomm, Ericsson, and Nokia discussed how 5G could transform industries ranging from transportation to manufacturing.

Some 5G rollouts are already planned for 2018. Samsung announced last Wednesday that it will provide Verizon with routers and radio frequency planning services for the carrier's initial 5G commercial rollout that will begin in Sacramento, Calif., in the second half of 2018.Meanwhile, AT&T announced that it will provide 5G services in roughly 12 markets by late 2018, with plans to offer the service to consumers while it trials 5G technology with businesses across all industries.Still, the panel of executives at CES remain skeptical that 5G would roll out for most Americans before late 2019 or 2020.

Some time on Tuesday afternoon, about 50,000 Comcast Internet customers in Houston will become part of a massive public Wi-Fi hotspot network, a number that will swell to 150,000 by the end of June. Comcast will begin activating a feature in its Arris Touchstone Telephony Wireless Gateway Modems that sets up a public Wi-Fi hotspot alongside a residential Internet customer’s private home network. Other Comcast customers will be able to log in to the hotspots for free using a computer, smartphone or other mobile device. And once they log into one, they’ll be automatically logged in to others when their devices “see” them. Comcast says the hotspot – which appears as “xfinitywifi” to those searching for a Wi-Fi connection – is completely separate from the home network. Someone accessing the Net through the hotspot can’t get to the computers, printers, mobile devices, streaming boxes and more sitting on the host network. Comcast officials also say that people using the Internet via the hotspot won’t slow down Internet access on the home network. Additional capacity is allotted to handle the bandwidth. You can read more about Comcast’s reason for doing this in my report on HoustonChronicle.com.

What’s interesting about this move is that, by default, the feature is being turned on without its subscribers’ prior consent. It’s an opt-out system – you have to take action to not participate. Comcast spokesman Michael Bybee said on Monday that notices about the hotspot feature were mailed to customers a few weeks ago, and email notifications will go out after it’s turned on. But it’s a good bet that this will take many Comcast customers by surprise. If you have one of these routers and don’t want to host a public Wi-Fi hotspot, here’s how to turn it off.

The additional capacity for public hotspot users is provided through a separate channel on the modem called a “service flow,” according to Comcast. But the speed of the connection reflects the tier of the subscriber hosting the hotspot. For example, if you connect to a hotspot hosted by a home user with a 25-Mbps connection, it will be slower than if you connect to a host system on the 50-Mbps tier.

"Just 40 miles west on the Kansas Turnpike from Kansas City Kansas sits Lawrence, KS. With the slow rollout of Google fiber in their neighbor city, it was looking like their 89,000 people were not going to get the gigabit fiber to the home for quite some time. Up steps Wicked Broadband, a local ISP. With a plan remarkably similar to Google's they look to build out fiber to the home, business, and so on with gigabit speed and similar rates, symmetric bandwidth and no caps. Wicked Fiber's offer is different than Google Fiber's, with more tiers — with cute names. The "Flying Monkey" gigabit plan is $100/month, "Tinman" at 100Mbps is $70/month. They offer TV as well but strangely put Internet streaming and Roku to the fore. They are even using Google's method of installing first in the neighborhoods with the most pre-registration to optimize efficiency, and installing only where there is enough demand. It seems Google's scheme to inspire competition in broadband access is working — if Wicked Fiber gets enough subscribers to make it pay. If this succeeds it may inspire similar ISPs near us to step up to gigabit fiber so let's root for them."

Ever wonder why most e-mail clients hide images by default? The reason for the "display images" button is because images in an e-mail must be loaded from a third-party server. For promotional e-mails and spam, usually this server is operated by the entity that sent the e-mail. So when you load these images, you aren't just receiving an image—you're also sending a ton of data about yourself to the e-mail marketer. Loading images from these promotional e-mails reveals a lot about you. Marketers get a rough idea of your location via your IP address. They can see the HTTP referrer, meaning the URL of the page that requested the image. With the referral data, marketers can see not only what client you are using (desktop app, Web, mobile, etc.) but also what folder you were viewing the e-mail in. For instance, if you had a Gmail folder named "Ars Technica" and loaded e-mail images, the referral URL would be "https://mail.google.com/mail/u/0/#label/Ars+Technica"—the folder is right there in the URL. The same goes for the inbox, spam, and any other location. It's even possible to uniquely identify each e-mail, so marketers can tell which e-mail address requested the images—they know that you've read the e-mail. And if it was spam, this will often earn you more spam since the spammers can tell you've read their last e-mail.

But Google has just announced a move that will shut most of these tactics down: it will cache all images for Gmail users. Embedded images will now be saved by Google, and the e-mail content will be modified to display those images from Google's cache, instead of from a third-party server. E-mail marketers will no longer be able to get any information from images—they will see a single request from Google, which will then be used to send the image out to all Gmail users. Unless you click on a link, marketers will have no idea the e-mail has been seen. While this means improved privacy from e-mail marketers, Google will now be digging deeper than ever into your e-mails and literally modifying the contents. If you were worried about e-mail scanning, this may take things a step further. However, if you don't like the idea of cached images, you can turn it off in the settings. This move will allow Google to automatically display images, killing the "display all images" button in Gmail. Google servers should also be faster than the usual third-party image host. Hosting all images sent to all Gmail users sounds like a huge bandwidth and storage undertaking, but if anyone can do it, it's Google. The new image handling will rollout to desktop users today, and it should hit mobile apps sometime in early 2014. There's also a bonus side effect for Google: e-mail marketing is advertising. Google exists because of advertising dollars, but they don't do e-mail marketing. They've just made a competitive form of advertising much less appealing and informative to advertisers. No doubt Google hopes this move pushes marketers to spend less on e-mail and more on Adsense.

Following up on its announcement at The Cable Show last month, Cox Communications is now offering more detail on the company's pending rollout of gigabit broadband services throughout its territories. (See Cox Goes for a Gigabit .) Cox Communications Inc. is targeting Phoenix, Las Vegas, and Omaha as its first new gigabit markets and plans to begin deployments across its entire footprint by the end of 2016. In addition to residential home service, the company will offer gigabit connectivity to select condominiums and apartments and will expand WiFi service both in common areas of those multi-dwelling units (MDU) and in public locations across the Phoenix and Las Vegas metro areas. The announcement by Cox, the first major North American MSO to make a 1-Gig commitment throughout its footprint, follows a recent pattern of competitive announcements from broadband service providers. Typically, one operator introduces or says it will explore delivery of higher broadband speeds, and then other local providers rapidly follow suit. In February, for instance, Google Fiber Inc. said it would look at expanding fiber service to 34 new cities, including Phoenix, where it will compete against Cox for the first time. (See Google Fiber Shifts Into High Gear.)

At the same time, CenturyLink Inc. (NYSE: CTL) began offering gigabit service in Las Vegas last fall and in Omaha last May, putting Cox on the hot seat in those two markets as well. This isn't Cox's first venture into gigabit broadband service. In addition to providing gigabit connections to commercial customers, the operator started a fiber-to-the-home trial service in Orange County, Calif. last year. For the company's upcoming deployments, a spokesperson noted that Cox hasn't yet specified which technologies it will use, but said that it will rely on portions of Cox's existing network in addition to newer fiber infrastructure.

Google has named the next four areas in the US to get its gigabit-a-second fiber broadband. The advertising giant said on Tuesday it will next roll out high-speed connections to 18 cities in and around Atlanta, GA; Charlotte, NC; Raleigh-Durham, NC; and Nashville, TN. Charlotte city officials had indicated they were expecting to be named as one of the next places to feel Google's cable. The expansion will bring the total number of areas with Google Fiber deployments to seven: the California biz already offers fiber broadband in and around Kansas City, MO, Austin, TX, and Provo, UT.

Google charges $70 a month for gigabit internet, $120 if you want TV with it, or free if you're happy with 5Mbit/s for the downlink. Only the freebie option requires a $300 installation fee. Despite the price tag, the service is hotly anticipated in the few chosen cities. The presence of Google Fiber also has the side-effect of spurring rival carriers, such as AT&T, to offer their own high-speed broadband services in the area.

Later this year, the Chocolate Factory will also make its decision on where the next set of Fiber rollouts will take place. Five areas are being considered: Portland, OR; San Jose, CA; Salt Lake City, UT; Phoenix, AZ; and San Antonio, TX. ®

While there is considerable telecom hubris regarding the 5G rollout and increasing speculation that the next generation of wireless is not yet ready for Prime Time, the industry continues to make promises to Rural America that it has no intention of fulfilling. Decades-long promises to deliver digital Utopia to rural America by T-Mobile, Verizon and AT&T have never materialized.  

In 2017, the USDA reported that 29% of American farms had no internet access. The FCC says that 14 million rural Americans and 1.2 million Americans living on tribal lands do not have 4G LTE on their phones, and that 30 million rural residents do not have broadband service compared to 2% of urban residents.  It’s beginning to sound like a Third World country. Despite an FCC $4.5 billion annual subsidy to carriers to provide broadband service in rural areas, the FCC reports that ‘over 24 million Americans do not have access to high-speed internet service, the bulk of them in rural area”while a  Microsoft Study found that  “162 million people across the US do not have internet service at broadband speeds.” At the same time, only three cable companies have access to 70% of the market in a sweetheart deal to hike rates as they avoid competition and the FCC looks the other way.  The FCC believes that it would cost $40 billion to bring broadband access to 98% of the country with expansion in rural America even more expensive.  While the FCC has pledged a $2 billion, ten year plan to identify rural wireless locations, only 4 million rural American businesses and homes will be targeted, a mere drop in the bucket. Which brings us to rural mapping: Since the advent of the digital age, there have been no accurate maps identifying where broadband service is available in rural America and where it is not available.  The FCC has a long history of promulgating unreliable and unverified carrier-provided numbers as the Commission has repeatedly ‘bungled efforts to produce accurate broadband maps” that would have facilitated rural coverage. During the Senate Commerce Committee hearing on April 10th regarding broadband mapping, critical testimony questioned whether the FCC and/or the telecom industry have either the commitment or the proficiency to provide 5G to rural America.  Members of the Committee shared concerns that 5G might put rural America further behind the curve so as to never catch up with the rest of the country

The much anticipated iPhone 5G - and the next obvious cash cow for smartphone technology company Apple in its long line of smartphone cash cows - may be put on hold due to spillover effects from the coronavirus. Bank of America put out a note on Friday morning, citing a conversation with an expert on the company's supply chain, that said the product launch may wind up being pushed back.  The expert said that  “the iPhone 5G launch in the fall could see a month of delay.” He also warned that the launch of the iPhone SE2 would be delayed by "a few months" due to supply issues and weaker demand as a result of coronavirus.
