special
inspections,
and
can
meet
the
needs
of
customers
for
rapid
development
and
application.

P401-DAI

operate
in
AP
and
Device
modes,
enabling
stable
and
reliable
long-range
wireless
communication.

Technical
Features
of
P401-DAI
Module
• Based
on
the
principle
of
TDD,
key
technologies
such
as
OFDM
and
MIMO
are
adopted
to
improve
the
utilization
of
frequency
bands.
• Supports
AES
encryption,
multiple
security
policies,
and
prevents
illegal
eavesdropping
and
interception.
• Adopt
a
frequency
hopping
scheme,
monitor
interference
in
real
time,
and
automatically
select
the
frequency
hopping
range;
based
on
the
interference
situation
of
the
current
channel,
automatically
and
quickly
change
the
frequency
point
and
adjust
the
Modulation
and
Coding
Scheme
(MCS).
• Supports
star
networking
plus
relay
networking,
enabling
the
construction
of
wireless
multi- hop
networking
applications.

• The
maximum
rate
of
air
interface
transmission
can
reach
40
Mbps.

2.1Frequency
Hopping
and
Sweeping
Mechanism

The
frame
structure
can
be
configured
and
supports
real-time
frequency
hopping
per
frame.
If
the
period
of
each
frame
is
5ms
(a
relatively
short
frame
structure),
then
200
hops
can
be
achieved
in
1
second.
Of
course,
for
one-to-many
applications,
the
frame
period
is
generally
around
several
tens
of
milliseconds.

It
supports
two
sweep
modes,
referred
to
here
as
short
sweep
and
long
sweep.
Short
frequency
sweep
is
mainly
used
to
conduct
interference
testing
on
frequency
points
within
a
frequency
band
(such
as
the
2.4G
frequency
band
or
5.8G
frequency
point),
and
only
requires
short
frequency
sweep
testing
at
the
receiving
end.
The
main
purpose
is
to
observe
whether
there
are
interference
signals
within
the
working
frequency
band,
identify
the
current
working
frequency
point
and
alternative
frequency
points
with
less
interference,
so
that
when
the
current
working
frequency
point
is
interfered
with,
frequency
hopping
can
be
performed
to
the
alternative
frequency
points.
Generally,
we
observe
interference
signals
from
-90dBm
to
-60dBm.

Long
sweep
frequency
is
mainly
used
to
evaluate
the
signal
quality
of
two
frequency
bands
(such
as
a
dual-band
system
with
2.4G
and
5.8G
frequency
bands).
The
transmitter
will
time- share
select
some
frequency
points
from
the
two
frequency
bands
to
transmit
known
sequences,
and
the
receiver
will
obtain
alternative
frequency
points
based
on
the
received
signal
to
noise
ratio,
preparing
for
future
frequency
hopping.
2.2Anti-interference
performance
characteristics
It
supports
interleaved
blocks
of
1.25ms,
2.5ms,
and
5ms.
Taking
the
5ms
interleaved
block
as
an
example,
it
can
resist
co-channel
interference
of
about
1ms.
This
has
a
good
performance
advantage
for
some
sudden
short
WIFI
packets.
When
combined
with
a
highly
real- time
frequency
scanning
and
hopping
mechanism,
relatively
good
anti-interference
performance
can
be
obtained.
