while the debate over the merits of touch screens and physical buttons has not yet ceased, the dispute between traditional am radios and networked digital audio software has tended to be "settled."

recently, the u.s. house of representatives energy and commerce committee passed the am radio for every vehicle act of 2024 (am radio for every vehicle act of 2024) by a vote of 45 to 2. the bill requires that vehicles manufactured and sold in the united states must equipped with am radio. the bill is currently before the house of representatives for consideration by the plenary.

coincidentally, on the same day, my country's ministry of industry and information technology publicly solicited opinions on the mandatory national standard formulation and revision plan for "vehicle wireless broadcast receiving system" and planned to require car companies to equip their vehicles with wireless broadcast receiving systems. the opinions pointed out that the vehicle-mounted wireless broadcast receiving system is an important infrastructure to ensure that the public can quickly and effectively receive authoritative emergency information during emergencies. it is currently in the opinion solicitation stage.

am radio, as a car wireless broadcast receiving system, has been a standard configuration of cars for a long time and is also a "good partner" for drivers and passengers during travel. people can choose their favorite radio programs through buttons or knobs. . however, in recent years, with the rapid development of the automobile industry in the direction of intelligence and digitalization, new energy vehicles and intelligent vehicles have canceled am radio configurations and replaced them with audio content such as music streaming through the internet.

according to incomplete statistics, new energy vehicle brands such as tesla, polestar, byd, and xpeng, as well as traditional automobile brands such as ford, mazda, and bmw, have not equipped am radio functions in new models launched in recent years. for example, tesla will cancel the am radio with am function in the model y and model 3 models made in china in 2021; xpeng and wenjie will cancel the in-car radio module in some models, and ford's 2024 mustang will not have the am radio function.

some automakers believe wireless broadcast reception systems are obsolete and that electric vehicle powertrains can cause electromagnetic interference to am signals. internet radio such as digital streaming media can replace traditional am radio functions and has higher technical adaptability to meet consumer needs.

why has am radio, which has been gradually "abandoned" by car companies, "returned strongly" at the policy level? the ministry of industry and information technology's "mandatory national standard project proposal" states that "the vehicle-mounted wireless broadcast receiving system is an important infrastructure that ensures that the public can quickly and effectively receive authoritative emergency information during emergencies. the wireless broadcast receiving system actively releases emergency information to drivers and passengers. it has unique advantages in developing natural disasters (such as earthquakes, floods, etc.) and other safety information.”

specifically, the coverage radius of fm radio transmitting stations exceeds 100 kilometers, and the coverage distance of medium wave radio stations can reach thousands of kilometers. the transmitting stations are far away from car drivers and passengers, and are less likely to be affected by the same disaster. the wireless transmission distance from the 2g/3g/4g/5g cellular receiving terminal to the base station required by the internet is hundreds of meters to thousands of meters. the possibility of car drivers and base stations suffering disasters at the same time is extremely high. therefore, when cellular base stations are damaged due to sudden emergencies such as earthquakes, floods, typhoons, etc., the wireless broadcast receiving system on the vehicle will play a key role.

am wireless broadcast receiving systems play a vital role in emergency communications during natural disasters or other crises. they can provide the public with timely evacuation, hazard avoidance and other information, which is especially critical when network signals are unstable or missing. . antwane johnson, director of the integrated public alert and warning system at the federal emergency management agency, said am radio has been tested over and over again in the most devastating natural disasters — and it has survived them all. additionally, radio stations are free and capable of reaching millions of people with a single broadcast.

not only the united states and china, but also the european union and japan have introduced relevant standards and mandatory measures for vehicle-mounted wireless broadcast receiving equipment. for example, the european union issued the 2014/53/eu radio equipment directive (red) in 2014, which stipulates that after june 13, 2017, only radio equipment that meets the red directive and has obtained ce-mark will be sold on the eu market. vehicle-mounted radios, vehicle-mounted digital audio broadcasts, vehicle-mounted wireless communication terminals, etc. all fall within the scope of the red directive.

the latest research results in "nature earth science" show that under high-emission scenarios, 70% of the global population may experience extreme weather in the next 20 years. providing am radios in cars will increase the chance that the public will receive emergency alerts and critical warnings when out in extreme weather.

according to foreign media reports, if the "vehicle am ​​broadcasting act of 2024" is finally passed, it will represent a major change in automobile regulation and radio broadcasting. the u.s. national highway traffic safety administration (nhtsa) will issue specific rules requiring automakers to comply within the next two to three years to ensure am broadcast reception is included in new vehicles at no additional charge to consumers.

the debate surrounding the am broadcast function is not only a test of the development of automotive technology, but also a deep thinking on how to protect public interests. with the rapid development of smart electric vehicles, legislators and the automotive industry need to find a dynamic balance between supporting technological innovation and protecting the bottom line of public safety.
