3G sunset, millions of affected connected vehicles where to go

Edited by Zhang Ou/Designed by Tu Yanping/Zhao HaoranAT&T, the largest carrier in the United States, officially shut down its 3G network on February 22, and other major carriers like T-Mobile and Verizon will do the same by 2022.It has been exactly 20 years since 3G technology was first brought to the United States in 2002, a generational technological farewell dubbed “3G sunset” by the telecom industry.The end of 3G will not only affect older mobile phones, but also other products in People’s Daily lives.Such as tablets, smartwatches, medical devices, SOS services for vehicles, home security systems and vehicles that use 3G networks for updates and remote communication.It’s probably the most overlooked topic in the auto industry right now, but the implications are potentially vast.There are plenty of vehicles with 3G embedded telematics control units, modems and antennas that work only on 3G networks.It involves millions of vehicles from nearly every major automaker, including brands like Tesla, Audi and Nissan.And not just older cars, but some new cars, trucks and SUVs from 2021 will also be affected.The resale value of all vehicles will also be squeezed.Over the years, cellular communications have evolved to deliver faster, more powerful and more reliable data.As 5G technology is becoming the standard and 3G services have to give up infrastructure and funding, keeping older networks fully operational will mean newer, more advanced networks and equipment will be unnecessarily constrained by a lack of available spectrum.When carriers don’t need to maintain older technology, they can use older 3G frequencies to expand 5G bandwidth.Whenever a new generation of cellular technology comes along, carriers, in coordination with government agencies such as the FCC, begin phasing out the oldest networks to free up spectrum and network resources for the newest — which can use that spectrum more efficiently.This happens with every generational shift, and it will be the same in 5G.The 4G/LTE networks most people use today will still be around for years — because 5G is designed to support dynamic spectrum sharing (DSS) technology, in which 4G and 5G devices share the same airwaves.According to the FEDERAL Communications Commission (FCC), the following are the offline dates for the major 3G network operators: AT&T 3G: February 22, 2022 T-Mobile (Sprint 3G TDMA) : March 31, 2022 T-Mobile (Sprint 4G LTE) :AT&T was the first major provider to shut down its 3G service, to be followed by T-Mobile and Verizon later this year.Other smaller operators that rely on these networks, such as Cricket, Boost and Straight Talk, will also be phasing out services.”Since February 2019, we have been working with automakers to help them transition their connected vehicles to newer technologies before 3G services end on February 22.””Customers have received and will continue to receive additional communications, including direct mail, billing messages, emails and text messages, as we work with them on this transition,” AT&T said in an emailed statement On Monday.Although suppliers have warned that their 3G networks will be permanently shut down for a while, many automakers are still partially installing equipment using older networks until 2021.The main features affected are the general vehicle telematics services that currently rely on 3G connectivity (depending on the different feature configurations and update plans of the major automakers) :Concierge service,Such as booking or roadside assistance navigation and traffic crashes

start remote lock/unlock “consumer reports” (published by the American consumers union consumerreportS.org, published a list of affected vehicles by brand.Owners who have not been contacted by the automaker can also check the brand’s web site or consult a car dealer to see if their vehicle is affected.The decision to shut down 3G services is up to the operators, not the carmakers.As a result, manufacturers have chosen different ways to respond.Do nothing, or rush to offer upgrades, including paid subscriptions.Some manufacturers are offering software and hardware upgrades, while others are offering new services that owners can pay a one-time fee or opt for monthly/annual subscriptions.”They are looking at how many people are really affected by the 3G shutdown, one by one, and judging the rationale and necessity of developing a particular upgrade based on the response.””Said Sam Abuelsamid, principal analyst at Guidehouse Insights, a market intelligence consulting firm.Tesla, for example, is charging owners of Model S cars built before June 2015 $200 to upgrade their modems, according to its website.It explains that without the upgrade, drivers will lose some remote features and certain infotainment features, including navigation, maps and real-time traffic updates.Owners of some Honda cars can download the software update for free through Tuesday.After that, they will have to pay at least $900 for hardware upgrades.Volkswagen, Audi and Stellantis, which owns Jeep, Ram and Chrysler brands, are offering third-party alternatives for some services.Audi and Volkswagen have teamed up with partner service provider Mojio to launch a plug-in device that connects to the vehicle’s telematics (or OBD) port to maintain emergency services.Audi owners will be able to enjoy the service free for a limited period of time before switching to a paid subscription plan.A gm spokesman says it has been sending remote updates since October to keep the service running.Other carmakers, such as Toyota, have not responded, merely watching service expire.”Although these conditions were caused by factors beyond our control, we sincerely apologise for any inconvenience.””– According to a statement on Toyota’s website.The Drive, an automotive portal, asked Toyota directly if it planned to offer upgrades to customers who own affected vehicles, paid for or otherwise, and The answer was a simple “no.”Ford is less affected by the 3G shutdown than those brands.They will also no longer offer older versions of the application.Plan B: Smartphone If the car doesn’t get a 3G to 4G upgrade without notice from the automaker and dealers are consulted to no avail, there’s an option B — replacing some features with a smartphone.Services linked to specific vehicle functions, such as remote lock/unlock, remote engine start and service tracking — are too difficult and are generally recommended to be abandoned;However, other features are very easy to replace.The Google Personal Safety app, for example, offers car crash detection and emergency service notifications.It can be found on many Android smartphones.Apple is reportedly working on similar technology for iPhone and Apple Watch users.The OnStar Guardian app offers mobile collision response and road assistance as part of a $15 monthly subscription and is available to drivers of any vehicle, not just GM models.Drivers who rely on Apple CarPlay or Android Auto for navigation won’t be affected.Because these systems are connected to users’ phones, the vast majority of which tend to use carriers’ 4G, LTE or 5G networks.And older cars that run their navigation systems through AN SD card won’t have any problems.Owners can choose to replace their vehicle’s infotainment system host with aftermarket accessories that support Android Auto and Apple CarPlay, thus replacing your connected transportation and navigation services.There are also many aftermarket options that support Amazon Alexa and its connectivity services.Wi-fi hotspots are easy to replace, open with a smartphone, and even work on faster 5G networks.Onstar’s 4G LTE dashboard system on the Chevrolet ImpalaThe sunset of service networks is nothing new to the auto industry, but the impact on consumers is becoming more widespread as many automakers take advantage of the opportunity to expand their connected car fleets and services in order to generate more revenue.Carmakers will face such a moment in the future with the 4G networks that are now widely used in new cars.Carmakers, telecoms companies and regulators need to do more to make sure such a surprise does not happen again.
