Stress-free with 5G

人工智能让家居生活更加轻松

After a long and busy day at school or work, all we want to do is return to a clean and

comfortable home. Smart technology can turn any home into a nicer place to live. You can now

turn your thermostat (恒温器) up, lock your doors and play your music with a simple voice

command.

In fact, smart homes have actually been around for some time. Scottish company Pico

Electronics invented a communication protocol (协议) called X10 back in 1975. With radio

waves, this protocol allowed users to communicate with various devices (设备) in their homes,

such as lights and alarms, according to AVSytemsMag, a magazine dedicated to the AV and

automation (自动化) industry.

Of course, 4G – and now 5G – wireless technology makes smart homes much more

sophisticated (复杂的) and powerful than X10 devices. Perhaps the most widespread smart

home technology is the voice-activated (声控的) assistant. Google Home and Amazon’s Alexa

allow users to interact (互动) with nearly any device in their homes simply by speaking a few

words. This is especially convenient for children and people with physical disabilities, as they

can accomplish tasks that would normally be too complicated or difficult, according to How-

To Geek magazine.

Common household appliances can become “smart” as well. For example, a smart trash

bin can monitor the things you’ve thrown away and place an online order for replacement items,

while smart refrigerators can create dinner recipes based on the ingredients that were kept inside,

according to HowStuffWorks website. 5G-powered sensors (传感器) and cameras can monitor

almost every aspect of household life.

The appeal of all of this convenience has paid off for realtors (房地产经纪人), who are

seeing sales of smart homes skyrocket (猛增). You can ask Dave Garland, a realtor with Second

Century Ventures.

“There’s a new narrative (表述) when it comes to what ‘home’ means,” he said in an NPR

report. “It means a personalized environment where technology responds to your every need.”

But it’s not just about convenience. Smart homes are also good for the environment. By

monitoring your energy use and automatically turning off lights and other devices that you’re

not using, smartphones can lower how much electricity you use overall. Using less energy

means that we use fewer resources such as coal and gas, which is ultimately (最终) good for

the environment – and our wallets.
