1.3. Choose a Radio Location
Placement of the FreeWave radio may have a significant impact on its performance. The key to
the overall robustness of the radio link is the height of the antenna.
When using an external antenna, placement of that antenna is critical to a solid data link. Other
antennas in close proximity are a potential source of interference.
Use the Radio Statistics on the Status window (on page 175) to help identify potential problems.
In general, FreeWave units with a higher antenna placement will have a better communication
link.
In practice, the radio should be placed away from computers, telephones, answering machines,
and other similar devices. The cable included with the radio provides ample distance for
placement away from other equipment.
Note: FreeWave offers directional and Omni-directional antennas with cable lengths ranging from 3
to 200 feet.
An adjustment as little as 2 feet in antenna placement may resolve noise issues.
In extreme cases, (e.g., Cellular Telephone tower interference) the band pass filters that
FreeWave offers may reduce this out-of-bandnoise.
1.4. Choose Point-to-Point (PTP) or Point-to-MultiPoint
(PTMP) Operation
PTP Network
l A PTP network functions best when the network consists of one Gateway and one
Endpoint radio.
l A maximum of four Repeaters can be added to extend the reach of the network.
Important!: Adding a Repeater to a network cuts the network throughput by 50%.
In a Point-to-Point network, the Gateway determines all settings in an Endpoint or Repeater,
except for the Transmit Power and Retry Timeout. All other settings in a Point-to-Point network
are determined by the Gateway's settings.
PTMP Network
In a PTMP network, the Gateway radio is able to simultaneously communicate with numerous
Endpoint radios.
l In its simplest form, a PTMP network functions with the Gateway broadcasting its
messages to all Endpoint radios.
l If requested by the Gateway, the Endpoint radios respond to the Gateway when given data

1.4.1. Differences between PTP and PTMP Networks
PTP Network
In a PTP network all packets are acknowledged, whether sent from the Gateway to the Endpoint
or from the Endpoint to the Gateway.
PTMP Network
In a PTMP network, the user determines the number of times outbound packets from the
Gateway or Repeater to the Endpoint or other Repeaters are sent.
l The receiving radio, Endpoint or Repeater, accepts the first packet received that passes the
32 bit CRC.
l However, the packet is not acknowledged.
l On the return to the Gateway, all packets sent are acknowledged or retransmitted until they
are acknowledged.
l Therefore, the return link in a PTMP network is generally very robust.
Traditionally, a PTMP network is used in applications where data is collected from many
instruments and reported back to one central site. The architecture of such a network is different
from PTP applications. These parameters influence the number of radios that can exist in a PTMP
network:
l Baud Rate. The data rate between the radio and the device it is connected to could limit the
amount of data and the number of radios that can exist in a network.
l Contention: The amount of contention between Endpoint radios. Polled Endpoint radios
versus vs. timed Endpoint radios.
l Data Block Size. The longer the data blocks, the fewer number of deployed Endpoint
radios can exist in the network.
l Repeater Use. Using the Repeater setting in a PTP or PTMP network decreases the
overall network capacity by at least 50%.
Example: If the network polls once a day to retrieve sparse data, several hundred Endpoint
radios could be configured to a single Gateway.
However, if each Endpoint transmits larger amounts of data or data more frequently, fewer
Endpoint radios can link to the Gateway while receiving the same network performance.
When larger amounts of data are sent more frequently, the overall network bandwidth is
closer to capacity with fewer Endpoint radios.

2.1. Basic Steps to Programming the FGR2-P, -PE, & -PE-U
PLUS Radios
This basic procedure programs any FreeWave PLUS Radio.
1. Determine or set the radio's IP address.
Note: The PLUS radio can be programmed using the terminal menu available through the
radio's serial port without having to know the radio's IP address.
2. Be familiar with the network and know if it is a Point-to-Point (PTP) or Point-to-MultiPoint
(PTMP) configuration.
Note: Most FreeWave networks are PTMP.
3. Open the radio's Configuration Windows.
4. Set the radio's operation mode (e.g., Gateway, Repeater, or Endpoint).
5. Set the radio's network type (PTP or PTMP).
6. Program the radio, verifying all devices in a PTMP network have the same settings for
these parameters:
l Frequency Key
l Max Packet Size
l Min Packet Size
l Network ID
l RF Data Rate
7. Setup the Call Book if the radio is in a network NOT using Network IDs.
See the Call Book window (on page 158).
FREEWAVE Recommends: While the Call Book is an option in Point-to-MultiPoint networks,
FreeWave strongly recommends using the Network ID feature in most applications.
If a large MultiPoint network is implemented using the Call Book and a radio needs to be added or
replaced in the network, each radio MUST be physically reprogrammed in the network and the new
serial number entered in the radio's Call Book.
This can be a time consuming process and can cause a delay in getting the network back up and
running.
Note: If using a Network ID, see the Network ID and Subnet ID parameters described in the Radio

2.1.1. PTMP Network Considerations
Planning is important when installing PTMP networks. A PTMP network requires that several
parameters are set consistently on ALL radios in the network. This includes:
l Frequency Key.
l Min and Max Packet Size.
l Network ID.
l RF Data Rate.
Important!: If several independent, PTMP networks are located in close proximity, it is very
important to include as much frequency and time diversity as possible using different Frequency
Key and Min and Max Packet Sizes.
2.2. Powering the FGR2-P, -PE, & -PE-U PLUS Radio
Connect the FGR2-P, -PE, & -PE-U PLUS Radio to a positive DC power supply with +6.0 to
+30.0 VDC (typically, +12 VDC).
The power supply used MUST provide more current than the amount of current drain listed on the
FGR2-P, -PE, & -PE-U Technical Specifications (on page 196) for the voltage used.
Example: When using +12 VDC, the power supply must provide current capability greater than the
drain that is required for transmit or greater than 550 mA.
Note: For any application where the radio is used in a UL-controlled environment, the power supply
MUST be a Class 2 power source. Using a dedicated power supply line is preferred.
Warning! If the power supply is above approximately +18 to +20 VDC, use a 1 ohm resistor in
line with B+ input to the radio.
Warning! If the power supply line runs outside the enclosure, use electrostatic discharge
(ESD) protectors to protect the radio from electric shock and transient voltage suppressors
(TVS) to protect from an over-voltage situation.
Using both helps to ensure long-term, reliable operation.
2.3. Identify and Change the FGR2-P, -PE, & -PE-U PLUS
Radio's IP Address
Note: In software versions 2.26 and later, the FGR2-P, -PE, & -PE-U PLUS radio can be
programmed through the radio's COM1 port without having to know the radio's IP address.

2.5. Accessing the Configuration Windows
Each FGR2-P, -PE, & -PE-U PLUS Radio includes Configuration Windows to identify, change,
and program its settings.
Note: See Configuration Windows for detailed information.
l A Web browser must be installed on the computer to access the Configuration Windows.
l The router / switch and/or the computer accessing the radio must be on the same subnet.
If the Subnet Mask for the network is 255.255.255.0, the first three octets, or sections, of the IP
address on the radio and the IP address on the computer MUST match. The last octet is unique.
Example: If the subnet mask is 255.255.255.0 and the radio's IP address is 198.168.111.100, then
the computer must have an IP address that begins with 198.168.111.
The last section of the IP address is unique to identify the device.
