霍尼韋爾溫度變送器

I

am___________,

and

what

we

would

like

to

do

is

make

this

presentation

informal,

informative

and

armyouwith

the

knowledge

you

will

needin

implementing

a

wireless

strategy

withinyour

facility.This

is

a

very

exciting

time!

What

we

are

aboutto

discuss

is

our

future.

Wireless

is

not

a

fade,

it

his

here

to

stay!

Now

what

our

objective

is

to

dotoday

is

to

help

familiarize

you

with

how

it

works

and

the

things

youshould

knowwhenlooking

to

use

this

technology.Honeywell

has

been

involved

inRF

technology

longer

then

cell

phones

have

been

available.

Many

of

you

may

not

know

that

we

are

heavilyinvolved

in

defense

and

avionics,

or

aircraft

communications

and

radar.So

as

we

travel

through

this

discussion

understand

that

this

is

new

to

our

world,

but

as

far

as

technology

goes

we

are

just

combining

aradio

to

asensor.

Thus

reducing

the

cost

of

wiring.Simple,

Safely

and

Securely.This

is

an

amazing

time.

No

other

technology

in

our

recent

time

has

sparked

the

level

of

interest

that

wireless

has.

Blame

it

on

your

car

key

fob’s!Has

anyone

ever

questioned

their

reliability?

Security?

I

think

not!

You

see

we

are

stepping

on

grounds

that

other

area’s

have

already

tested

andproved.

Then

we

combine

that

withanother

layer

of

security

and

“Waalaa”

we

have

asolid

strategy

that

may

save

your

company

millions!

I

amnot

talking

thousands,

I

amspeaking

about

hundred’s

of

thousands
