)In
2009, Dan Black was hit by a car in his hometown
of Chepstow, Wales,
as he was biking to
his job at a grocery store. The accident left him
unable to move from the chest
down.
During his recovery, he suffered a stroke that
made his right arm useless. Once a promising
guitarist, Dan, now 25, lives with his
parents and requires around
?
the
?
clock care that costs
nearly
$$300
，
000 a
year. After the accident, a friend of him started
the Help Dan Black Fund(
基金
)
to cover
some of
Dan’s
medical expenses. Dan
learned about an experimental stem
cell(
干细胞
) treatment in
China that could enable him to walk
again. After four
years, donations to
help Dan Black totaled
nearly
$$30
，
000.
One day,
in 2013, a news story caught the eye of
Dan’s
mother, Michacla, who
then shared the
story with her son. The
story featured a five
?
year
?
old boy named Brecon Vaughan.
He had a rare
form of disease and never
walked by himself. The boy
’
s
family had created a website with which to
raise nearly
$$100
，
000 needed for a trip
to the Children
’
s Hospital,
where treatment was
offered that could
help Brecon walk. Only half the amount had been
raised, said the report.
Dan
deliberated. Then, after considering that his own
dream of walking could be years away, he
donated his
$$30
，
000 to
Brecon
’
s cause.
“
I know how it feels to
walk. Brecon doesn
’
t. He
needs
it much more than I
do
，
”
Dan told a newspaper.
Dan
’
s generosity
received a great deal of attention, and
contributions started pouring in to the
Vaughan website. The family soon
exceeded their fund-
raising goal.
They’ve
promised to give the
extra funds, about
$$17
，
000, to the Tree of Hope
charity, which helps sick children in the United
Kingdom find specialized medical help.
In October, Brecon and his family traveled to St.
Louis to
begin treatment.
“
What Dan did is
great
，
”
Brecon
’
s mother
said.
“
It is an
extraordinary gift.

B
Slowly but
surely, we
’
re moving closer
and closer to 5G world. From
smart home
security to self-
driving cars, all the
internet
?
connected devices
in
our
life
will
be
able
to
talk
to
each
other
at
lightning
?
fast
speeds
with
reduced delay. Objectively speaking,
the fastest 4G download speeds in the
U
．
S. top out at
an average of 19.42 Mbps. But by comparison 5G
promises gigabit(
千兆
) speeds.
“
5G is one of those
heralds(
预兆
), along with
artificial intelligence, of this coming data
age
，
”
said
Steve
Koenig,
vice
president
of
market
research
for
the
Consumer
Technology
Association.
“
The self-
driving
vehicle is a great emblem of this data age, and
that is to say, it is a sign of time,
because with one single task, driving,
you have massive amounts of data coming from the
vehicle
itself,
and
a
variety
of
sensors
are
collecting
a
lot
of
information
to
model
its
environment
as
it
moves. It
’
s
pulling in data from other vehicles about road
conditions down the lanes. It could be
weather information, or connected
infrastructure(
基础设施
)
construction.
There’s
lots
of data behind
that task, which is why
we need the capacity and high
speed.
”
And
virtual
reality
glasses
and
headsets
haven
’
t
yet
become
the
mainstream,
but
tech
companies are joyfully
betting that these devices will eventually replace
our smartphones. With 5G,
that
could
actually
happen.
This
is
notable
because
companies
such
as
Apple
are
reportedly
developing AR
glasses to assist
—
or even
replace
—
smartphones.
Ericsson stated at
February
’
s Mobile World
Congress how smart glasses could become faster
and
lighter
with
a
5G
connection,
because
instead
of
being
weighed
down
with
components,
the
glasses could rely on hardware for
processing power.
But
don
’
t get too excited.
There
’
s still a lot of work
to be done in the meantime, including
various trials to make sure the radios
play nicely with hardware and infrastructure
construction, so
5G
isn
’
t concentrated only in
big cities.
