Select Link Monitor Period. 6.
Configuration Setting Throttling (Remote Station Only) Throttling limits the amount of data that passes though a remote Hopper Plus 120-24 unit. When throttling is enabled, the amount of data passed is equal to the throttling level times 128 kbps, to a maximum of 6.4 Mbps. Throttling applies to both the down link and up link traffic, so a setting of 128 kbps means the unit can pass 128 kbps in each direction. When throttling is disabled, the unit allows up to the maximum available bandwidth.
Radio Module Configuration Radio Module Configuration Changing the configuration settings of a Hopper Plus while it operates in a system could disrupt service. To prevent disruptions when the configuration is being changed, the Hopper Plus stores configuration information in three different states: New The intended configuration changes. Temporary. Current The configuration actually running on the unit. Temporary. Flash The configuration that was stored last in FLASH memory.
Configuration Setting the Station Type Each Hopper Plus 120-24 unit must be defined as a base or a remote unit. In any given system there is only one base unit, but there can be numerous remote units. To set the station type 1. From the Main Menu, select Radio Module Configuration. The Radio Module Configuration window is displayed. Radio Module Configuration New Current Station Type -> Remote Unit Remote Unit Station Rank (1-1000) 1 1 Center Frequency 2.4400 GHz 2.
Radio Module Configuration Setting the Station Rank For a base station, rank is the number of remotes that the base polls (regardless of the actual number of remotes in the system). The base station rank should equal the number of remotes so the base does not waste time polling nonexistent remotes. For a remote unit, rank is a unique number that identifies the remote to the base station. The base station polls remote units sequentially from rank 1 to the base unit s station rank, then repeats the process.
Configuration Setting the Center Frequency The center frequency defines the channel the unit uses to transmit and receive RF energy. To ensure communication between units, all units in a system must have the same center frequency value. To set the center frequency 1. From the Main Menu, select Radio Module Configuration. The Radio Module Configuration window is displayed. Radio Module Configuration New Current Station Type Remote Unit Remote Unit Station Rank (1-1000) 1 1 Center Frequency -> 2.4400 GHz 2.
Radio Module Configuration Setting Security Passwords Up to five different passwords can be set for a unit. Only Security Password 1 is required, the other passwords are optional. The higher the number passwords that are used, the higher the level of security for the unit. The set of passwords on the remote unit must match the set of passwords on the base unit. All passwords are exchanged between units, even when l password are not used.
Configuration Setting the Scrambling Code The scrambling code is used to scramble messages so only units with the correct scrambling code will be able to read messages. The scrambling code can be 0-32 bits long. Note: All units in the same network must have this setting set to the same value. To set scrambling codes 1. From the Main Menu, select Radio Module Configuration. The Radio Module Configuration window appears.
Radio Module Configuration Setting the Acquisition Code The acquisition code ensures that the receiver does not process any signals not intended for that receiver. The receiver processes only signals with the correct acquisition code. Note: All units in the same network must have this setting set to the same value. To set the acquisition code 1. From the Main Menu, select Radio Module Configuration. The Radio Module Configuration window is displayed.
Configuration Setting Config Test Minutes Since there is a chance that RF configuration changes will disrupt communications, each unit returns to its pre-configuration state after a timeout (unless the changes are saved to FLASH before the timeout). This timeout is set with the Config Test Minutes parameter, which can be set from 1 to 120 minutes.
Radio Module Configuration Setting Repeater Mode (Base Station Only) When a base unit has repeater mode enabled, it re-transmits messages to all remotes in the same RF group. When repeater mode is disabled, remote-to-remote traffic is allowed if radio communication is possible and remotes are in the same non-zero RF group. To set the repeater mode 1. From the Main Menu, select Radio Module Configuration. The Radio Module Configuration window is displayed.
Configuration Setting System Symmetry Type (Base Station Only) System symmetry type defines the amount of priority the base unit has when polling the remotes. The default setting "asymmetric" gives the base unit a time slot after each remote is polled—an asymmetric system is appropriate when the base is the access point to a large network.
Radio Module Configuration Setting Dynamic Polling Level (Base Station Only) The Hopper Plus uses dynamic polling to reduce overhead caused by idle remote units. Every remote unit is polled by the base, and idle units are ignored for the number of polling rounds entered in the Dynamic Polling Level field. Dynamic Polling is most effective in very large systems, where polling delay can become significant. Important: Polling level is set only for the base unit. To set the dynamic polling level 1.
Configuration Setting Remote Unit RF Group Remote unit RF group controls how remote units communicate with each other. Only remote units in the same non-zero RF group can communicate directly with each other. A remote with a zero RF group can only communicate with the base unit. To set remote unit RF group 1. From the Main Menu, select RF Module Configuration. The Radio Module Configuration window is displayed.
Radio Module Configuration Rebooting and Saving RF Configurations A reboot is required for temporary changes to the RF configuration to take effect. If the changes are valid, they can be saved "permanently" in the FLASH memory. If the changes are not valid, then the old configuration is restored after a programmable time-out. To reboot new RF configuration 1. From the Main Menu, select Radio Module Configuration. The Radio Module Configuration window is displayed.

Appendix A: Planning Your Wireless Link To ensure an effective and reliable wireless link, you need to perform some preliminary network planning before you install any hardware. These steps include: ¥ determining the physical layout of your planned link ¥ planning your antenna and fade margin requirements ¥ configuring your RF link. Planning the Physical Layout Before you install the units, you must determine the physical locations for each component of the Hopper Plus 120-24 wireless system.
Appendix A: Planning Your Wireless Link ¥ ¥ ¥ potential wind load and ice loading impact on the antenna regulatory restrictions, such as height, on antenna mast usage in the identified location grounding requirements. You must ensure that your antenna is properly grounded for lightning and installed according to the relevant electrical code for the location.
Optimizing the RF Link The following dB terms are used in this section: Term Description dB Decibel. A relative measure of power used to specify power gains and losses. The difference in power P1 and P2 expressed in dB is: P1 dB = 10 × log ------- P2 dBd The gain or loss of an antenna reference to a standard dipole. Gain of a Standard Dipole (dBd) = 2.14 dBi. dBi The gain or loss of an antenna referenced to an isotropic (theoretical point source) radiator.
Appendix A: Planning Your Wireless Link Working with System Gain The system gain of a radio system is the difference between the transmitted power and a receiver s sensitivity threshold. The system gain of the Hopper Plus 120-24 is: 74 Formula: System Gain = Transmission Power - Receiver Sensitivity @ 10-6 BER Variables: Hopper Plus 120-24 Tx Power = Receiver Sensitivity = 18.5 dBm - 83 dBm (receiver sensitivity @ 10-6 BER) Calculation: Hopper Plus 120-24 18.5 dBm - (-83) dBm = - 101.
Optimizing the RF Link Calculating EIRP (Effective Isotropically Radiated Power) EIRP is the power radiating from an antenna, taking into account the output power from the transmitter, the connector and cable losses, and the antenna gain. Unlike the Tx output power of the devices, EIRP is subject to both antenna gain and cable losses. Many antennas provide a directional gain, which can increase the effective radiated power. Losses such as cable losses subtract from this amount.
Appendix A: Planning Your Wireless Link Optimizing Antenna Gain To ensure the best range and interference suppression, the external antenna should be directional, focusing the radio energy in one direction (toward the other end of the link). A directional antenna focuses the RF energy to the intended station rather than omni-directionally. This reduces interference from other systems operating at the same frequency.
Optimizing the RF Link The Fresnel Zone is the expansion of the RF signal radio angles in the vertical plane near the middle of the RF path. Following diagram shows a Fresnel Zone: Fresnel Zone First Fresnel Zone Line of Sight The maximum Fresnel Radius indicates that this path must be kept clear of obstructions. Fresnel Radius Ground For the 2.4 GHz band, the approximate Fresnel Radius calculated as follows: Formula: Fresnel Radius (meters) = 3.4 d km 2 d km + ---------- 8.
Appendix A: Planning Your Wireless Link Calculating Path Loss Path loss describes the total RF attenuation throughout the system from Tx antenna to Rx antenna. This includes the losses as the RF signal travels through space plus Tx and Rx cable loss, and Tx and Rx connector loss. Use the following formula to calculate path loss: Formula: Path Loss = Tx and Rx Cable Loss + Tx and Rx Connector Loss + Propagation Loss Once you know the path loss, you can compare the value to the system gain value.
Link Budget Example Link Budget Example The values for cable and connector losses in this example are only for illustration. You will need to work these out for your specific installations.
Appendix A: Planning Your Wireless Link Antenna Basics Antennas focus and absorb radio energy in specific directions, depending on their design. They can be tuned to certain frequency ranges; the Hopper Plus 120-24 antennas must be tuned to 2.4 - 2.5 GHz. This section contains some basic information about antenna parameters and how to select and install antennas for use in your wireless system.
Antenna Basics Parameter Description XPD • Polarity and Cross-Polarization Discrimination (XPD). • Antennas have an associated polarity, which is the orientation of the radiating element with respect to earth. • Antennas are usually described as vertical, horizontal, or circularly polarized. The polarity of all antennas used in a system must be the same. • Cross-Polarization Discrimination specifies the signal isolation achieved when the receiving element is perpendicular to the radiating element.
Appendix A: Planning Your Wireless Link Selecting Antennas There are several factors to consider when selecting the right antenna for a wireless application. Following are some initial questions you should ask before selecting an antenna: ¥ What is the operating frequency range? ¥ Will this be a point-to-point or point-to-multipoint application? Ensure that you consider if the application will change in the future.
Antenna Basics Factor Description Maximizing the Hopper Plus 12024’s Capabilities • • • • • Safety • Proper grounding of antenna apparatus in accordance with respective Electrical Code(s) is crucial. • Wi-LAN recommends using a surge arrestor where the antenna cable enters the building. • All installations should be completed by a qualified and competent RF technician. EIRP • Effective Isotropically Radiated Power (EIRP) • EIRP is the amount of power that is transmitted to the air from the antenna.

Antenna Basics Fine-tuning Antennas You can fine-tune the antennas by physically moving the antenna. When the remote antenna is correctly aligned, the AIR LED is orange, indicating appropriate reception and acknowledgment of sync tokens from the base station. You can use the Receive and Transmit operating modes to test the link while adjusting the antennas to minimize BER and lost packets, and maximize received power. You can use the RSSI operating mode to maximize RSSI.

Glossary A absorption Antennas mounted too close to soft objects, such as trees, may experience a reduction in signal strength due to absorption. Absorption is most often encountered in applications installed during the fall or winter months. The problem does not become evident until the spring. acquisition code To minimize the effects of interference, all units in a system use the same acquisition code so the receivers can distinguish the desired signal from interfering signals.
Glossary as the -3 dB points. A high gain antenna has a very narrow beamwidth and may be more difficult to align. BER Bit Error Rate. A percentage of bits per million, showing the number of bits in error compared to the data bits actually sent. blocking Blocking is an operating mode where the radio receives only. Unblocked is the normal operating mode. C cable loss The signal loss experienced as it passes through the coax cable. Expressed in dB.
dBd dBd is antenna gain referenced over a half-wave dipole which is an antenna that has a donut shaped radiation pattern. Gain of a Standard Dipole = 2.14 dBi. dBi dBi is antenna gain referenced over an isotropic radiator which is a theoretical antenna that radiates equally in all directions (e.g. the sun). Wi-LAN references antenna gain in dBi. The conversion factor is: 0 dBd = 2.14 dBi dBm A power measurement referenced to one milliwatt.
Glossary ERP Effective Radiated Power. The power radiating from an antenna taking into account the output power from the transmitter, connector losses, cable losses, and the antenna gain. ETSI European Telecommunications Standards Institute. F fade margin The amount that the system gain plus the total antenna gain exceeds the path loss is called the fade margin. The fade margin is calculated as the number of dB that the received signal strength exceeds the minimum receiver sensitivity.
ISM Industrial, Scientific, and Medical. It is the family of license-exempt radio bands in North America and some European countries. It is also referred to as part 15.247 in the FCC regulation that defines the parameters for use of the ISM band in the U.S., including power outputs, spread-spectrum, and noninterference. L link monitor A Hopper Plus 120-24 utility that sends known data over an active system to test the reliability of the RF link.
Glossary overhead Anything that reduces the payload capacity of a system is overhead, even if serves a useful function. The link monitor data is used to determine transmission statistics, but it reduces the message carrying capacity of the Hopper 120-24 system and is considered overhead. P path loss The total loss from one end of the path to the other. This includes propagation losses, cable losses, and any other losses that impact the system performance.
shadowing Shadowing is a form of diffraction that is typically caused when antennas are mounted too close to a structure, and they lose a portion of the signal lobe due to reflection. The receive antenna is in a shadowed area. To minimize shadowing, ensure that there is adequate height above when mounting antenna equipment to a structure. SNMP Simple Network Management Protocol.
Glossary isolation achieved when the receiving element is perpendicular to the radiating element. This can be advantageous when co-locating radio systems. V VSWR (Voltage Standing Wave Ratio) VSWR is the voltage ratio of minimum to maximum across a transmission line. A VSWR of 2.0:1 or less in an antenna is considered effective. Most antennas have a VSWR of 1.5:1. For example, when using a radio with a 4 watt output with an antenna VSWR of 1.5:1, the reflected power will be 160 milliwatts.
