THEORY OF OPERATION

INTRODUCTION
ESTeem wireless modem products provide a "Wireless Solution" by eliminating conventional hardwiring of leased phone lines.
All of the ESTeem models come with the industry standard RS-232C, RS-422, and RS-485 asynchronous communications ports
to give the user a new dimension to "Local Area Networking".
Our packet burst, frequency agile communications products allow the user to create a "Radio Area Network" of up to 255 users
on a single frequency. The packet burst communications technique was chosen to give the system very high data integrity in
high noise industrial environments. The ESTeem incorporates a method of error checking that provides received data accuracy
of greater than one part in 100 million.
Internal Digi-Repeater features allow the user to increase operating range by relaying transmission through a maximum of three
ESTeems to reach the destination ESTeem. An ESTeem can operate as an operating node, a repeater node, or both
simultaneously for added flexibility.
"Private Data Communications" is provided by the use of an interleaving technique of the modulated data, user definable
commands for unit addressing, network addressing, and security lock-out of software programming. If higher security is
required, the ESTeem is compatible with asynchronous Data Encryption Standard (DES) encryption devices.
The ESTeem has programmable software commands to allow the user to easily configure the unit for any application or mission.
The ESTeem setup parameters are saved in non-volatile memory.
When you buy ESTeem products you are getting equipment designed by the company that holds the United States and
Canadian patent for the wireless modem. We are proud to say that we design, develop and manufacture our products in the
United States. Each ESTeem is subjected to a rigorous quality control bench test before shipping to insure our customers have
out-of-the-package reliability. We also have a dedicated Customer Support Staff, Field Engineering Services and Factory
Training classes to make sure that your application problems are solved.
HOW IT WORKS
Now, as you can probably guess, the ESTeem is a sophisticated piece of technology, however the concept is easy to
comprehend if you understand packet radio.
All packet systems, whether hardwired or radio, share the same principle of operation; data is taken from your standard RS-232C,
RS-422, or RS-485 asynchronous port and is transmitted in "Blocks". Think of this block as an "Electronic Envelope" that we
call a packet. The size of the packet can be defined by the user from 1 to 2000 bytes of information. Reducing the size of the
packet allows the ESTeem to operate better in high EMF noise environments, because by reducing the packet size you reduce
transmission exposure time on the radio waves thereby increasing your probability of a successful transmission.
Once this packet of data is formed, it’s transmitted in a "burst," one ESTeem to another, hence the term "packet burst
communications". Now, if more than one packet is required to send the data then the ESTeem goes into full automatic mode and
transmits additional packets.
Before an ESTeem transmits its packet it listens to ensure that the air waves are clear before transmitting. This listen before
transmit scheme is called "carrier sensed multiple access," or CSMA.
When a "packet" has been transmitted, every modem in radio range on the same frequency hears it. To design a modem to
communicate with a network of modems it has to be "address specific" so only the modem you want to talk to accepts your
information. It's like yelling into a crowd of 255 people but you want only the person’s name you called to acknowledge (ACK).
CHAPTER 7
THEORY OF OPERATION
Revised: 9 Oct 03 7-2 EST P/N AA104
Well, very simply, that's how the ESTeem works. Once the address you're calling receives your packet, it's checked for
accuracy.
Accuracy is probably the single most important part of any communication device. The ESTeem uses Forward Error Correction
(FEC) and a 32 bit Cyclic Redundancy Check (CRC) which is a very sophisticated method of checking the data integrity of the
packet once its been received. The CRC insures data integrity greater than one part in one hundred million. Once the CRC is
completed on the received packet, the data is outputted to the user and a positive acknowledgment (ACK) is transmitted back to
the sender.
It's safe to assume that the data you receive is good data or you get nothing at all using the CRC technique. If no ACK is
returned after a given delay, the sender assumes the packet was not received and "retries" the transmission. The number of
retries are user definable from 1 to 255, allowing the unit to automatically retry sending the packet.
SPECTRUM UTILIZATION
The ESTeem uses a "listen before transmit" or Carrier Sensed Multiple Access (CSMA) scheme. This means only one unit in a
network is allowed to transmit at a time. By fixing each user's communication window and allowing the computer in the ESTeem
to be the Air Traffic Controller, many individual users can share one frequency. The ESTeem firmware can support up to 255
ESTeems on a single channel or frequency. For example in the United States there are 1600 frequencies (12.5 kHz channel
spacing) in UHF, giving a network density of greater than 408,000 users in a given cell or geographical area. Once you are out of
radio range, you can construct another cell of users.
The CSMA technique is a very efficient way to manage your network of ESTeems and prevent communication bottlenecks. In
addition, an anti-collision software scheme is used to recover data if two or more units transmit at exactly the same time. When
this feature is added the technical term for this technique is now called CSMA-CD (collision detection).
By using this communications technique only one frequency channel is needed with a very narrow bandwidth (this is called
narrow band FM modulation) thereby saving valuable radio spectrum space.
PACKET PROTOCOLS
By using CSMA no polling station or token is required in the ESTeem network. When an ESTeem has information to send it will
check to see if the channel is clear before transmitting its packet and await an (ACK). The ESTeem is a Master/Master system,
meaning any ESTeem can communicate with any other ESTeem.
FLOW CONTROL
The ESTeem supports hardware and software flow control, which allow different devices on the network to communicate at
different baud rates. In addition to flow control the ESTeem also has a 4000 byte data buffer on both the receive and transmit
buffers in the unit.
DATA PRIVACY
Data privacy in the ESTeem is provided by three levels of data encoding in the firmware and by the user being able to define
over four security and communications parameters (Unit Address, Network ID, and Operating Frequency) that allow
communications access to the modem giving over 100 million combinations. If higher security is required, the units are
compatible with asynchronous Data Encryption Standard (DES) encryption peripherals.

THEORY OF OPERATION
Revised: 9 Oct 03 7-3 EST P/N AA104
EFFECTIVE BAUD RATE
The maximum input baud rate to the modem is 19,200 baud, asynchronous, full duplex, but this is misleading since the ESTeems
actually communicate to each simplex over the RF link, at 19,200 bps (25 kHz channel spacing - Model 192C/F) or 9,600 bps (12.5
kHz channel spacing - Model 192C/F). The effective baud rate is a function of the above plus the packet length variable in the
ESTeem (definable from 1 to 2000 bytes). If the packlength variable is set to 2000 bytes the effective baud rate is approximately
18,000 baud (25 kHz channel spacing) or 9,000 baud (12.5 kHz channel spacing) the effective baud rate will degrade as the
packlength variable is reduced.
Another item that must be understood is transmission turn around time. Remember that the ESTeem sends a data packet and
waits for an (ACK) from the destination modem before another packet is transmitted. All radio transmitters have a fixed delay
time, this is the amount of time it takes the transmitter to stabilize once it is energized before it can send data. In the ESTeem the
delay is approximately 15 milliseconds one way which includes transmitter turn-on time and packet frame overhead or a total turn
around time accounting for the (ACK) of 30 milliseconds. Therefore total time to send a data packet is 30 milliseconds plus the
time required to send the data (i.e. number of bits sent/19,200 b/s).

The SEL/A1 command sets the transceiver for a specific frequency.
SEL/N1 (1-56635)
The SEL/A1 command sets the transceiver for a specific frequency.
SEL/N2 (1-999)
The SEL/N2 command sets the transceiver for a specific frequency.
SETCon (r1,r2,r3,da)
This command defines the destination address for the ESTeem to perform a connect using the Auto Connect feature. This
function supports a direct connect or a connect through a maximum of three repeaters.
r1 = ESTeem address (1 to 254) of repeater 1.
r2 = ESTeem address (1 to 254) of repeater 2.
