hi I'm Lisa and this is threshold in

China today we are going to share some

exciting Tech Innovations an

announcement that happened in China

recently the next generation of mobile

communication is on its way and is

called

5.5g while 5G networks are still being

implemented worldwide Telecom companies

and Tech Giants are already looking

ahead to

6G however before we get to 6G there is

an important transition phase known as

the 5.5g or 5G Advanced recently Huawei

officially released the world's first

comprehensive 5.5g intelligent core

Network solution this solution is

currently undergoing joint testing with

multiple carriers in regions such as the

Middle East Asia Pacific Europe and of

course in China the aim is to pave the

way for large scale Global

commercialization of

5.5g as early as this year but what

exactly is 5.5g and why is it necessary

as the name suggests

5.5g is an intermediate step between 5G

and 6G while the addition of the 0.5g

may not seem significant but it offers

improvements in areas like connection

speed latency that is the time it takes

for data to travel position and accuracy

and

reliability in fact it is expected to

deliver performance boost of

approximately 10 times compared to the

initial 5G networks one of the biggest

advantage of 5.5g is faster data speed

while 5G is download rate starts around

one gips 5.5g can reach up to 10 gips

this is important for demanding

applications like extended reality and

naked

i3d upload speeds while also increase

from hundreds of mips to over one gips

enabling capabilities such as mass cloud

data transfer and widespread holographic

communication but of course there are

more to offer than just faster speeds it

improves connectivity in all situations

supporting trillions of connected

devices these device can range from fast

and industrial machines to small iot

sensors with 5.5g data travel time

latency will be reduced to just a few

milliseconds the accuracy of location

identification can also improve from

meters with 5G to centimet with

5.5g in simple terms 5.5g makes

connections more reliable faster and

precise for all types of devices not

just phones and computers these

technical capabilities ities will drive

transformations in various Industries

for example in manufacturing the super

fast speeds and low latency of 5.5g will

allow for better remote monitoring of

machines realtime data analysis and

optimized supply chain Logistics Cutting

Edge sectors like artificial

intelligence AR VR and brain computer

interfaces will finally have the

powerful networking they need to reach

their full potential China has

established the fast 5.5g demonstration

Zone in Beijing to Showcase its

advantages such as fully automated smart

Logistics using a fleet of self-driving

delivery vehicles with 5.5 G's huge

bandwidth sensor data from these

vehicles can be continuously uploaded to

frequently retain the AI Driving Systems

making them safer every day China's

major telecommunication companies have

started Regional trials for f .5g for

example China mobile aims to cover more

than 300 cities with 5.5g this year

while 5.5g is coming soon the

development of 6G is still under way

with a planned Road out around 2030 on

another note the United States and nine

other nations have endorsed a set of

principles to Advanced 6G technology due

to the intensifying competition with

China in developing the Next Generation

wireless

connections in a joint statement these

nations outlin principles for 6G systems

including the use of trusted technology

protective of National Security analysts

view this as an attempt to limit China's

6G development however given China's

large market and the independent

strategies of tech giants like Huawei it

is uncertain as to how effective they

are in slower China's

development imagine being able to charge

your electric vehicles in just 10

minutes even in freezing temperatures as

low Asus 80° C scientists from Jang

University in China have made a

significant breakthrough in Battery

Technology they have developed a new

electrolyte a key component of lithium

iron batteries that allows them to

operate and charge efficiently at

extremely low temperatures for years

lithium ion batteries have struggled to

perform well in cold conditions limiting

their use in electric vehicles Aviation

and polar exploration but was this new

electrolyte made up of tiny solvent

molecules that could be

changed this work is so groundbreaking

because high energy density wide

temperature operating range and fast

charging have been impossible to achieve

simultaneously in previous battery

designs because these properties seems

to contradict one another another

increasing energy density of the meant

using electrc materials that were less

stable in extreme temperatures

electrolytes that enable fast charging

could sacrifice energy density or

temperature

resilience and designing for a wide

temperature range often compromise

energy density or charging rate it has

been a challenge to optimize all three

factors simultaneously with conventional

battery designs however the new

electrolyte made from time flu aceton

trial solvent molecules overcomes these

challenges it has a unique Lian Channel

transport mechanism that allows for

Ultra efficient lithium ion

movement this mechanism enables the new

electrolyte to achieve high energy

density a wide temperature operating

range and fast charging it allows for

Ultra fast iron transport even at

freezing temperatures in fact compared

to Conventional electrolyt the new

electrolyte has an incredible

High ionic conductivity 10,000 Times

Higher at -70° C the research has also

found that this electrolyte design

principle is also effective for sodium

ion and potassium ion batteries

expanding the possibilities for energy

storage solutions while this work is

currently approved concept there are

still challenges to address before this

technology can be commercialized one

potential challenge is lowering the cost

of the solvent used in the electrolyte

however the lead scientist Professor f

sholing is optimistic and believes that

this electrolyte can reach commercial

use in the future and that is all for

today's threshold we hope you like this

China as usual we welcome your feedback
