2.4 Guidelines for Selection of Equipment Locations

Select appropriate locations for the Outdoor unit and for the Indoor unit usingthe following guidelines.

SU-RA

• The SU-RA Outdoor unit should be mounted on a pole and should beinstalled on a rooftop or a side-wall where a direct line of sight with the BaseStation antenna can be established. The higher the unit, the better theachievable link quality.

• The antenna (integrated on the front side of the SU-RA Outdoor unit) shouldbe directed towards the Base Station. The unit should be installed in a waythat allows optimal alignment towards the Base Station. The location shouldalso be selected to allow easy access to the unit for installation and testing.

SU-RE

• The SU-RE outdoor unit should be installed as near as possible to its antenna.

• The antenna should be mounted on a pole and should be installed on a rooftop or side wall where a direct line of site with the Base Station can beestablished. The higher the antenna, the better the achievable link quality.

• The antenna should be directed towards the Base Station. The antennashould be installed in a way that allows optimum alignment towards the BaseStation. The location of the antenna should allow easy access for installationand alignment.

SU-RA/RE

• The SU-RA/RE is connected to the SU-NI by means of an IF cable carryingsignaling, control signals and power. The IF frequency is 440 MHz. Themaximum allowed attenuation of the IF cable connecting the Outdoor unit tothe Indoor unit is 15dB and the maximum allowed DC resistance (the sum ofthe DC resistance of the inner and outer conductors) is 1.5 ohm. This allowsfor cable length of up to 30m when using the standard RG 58 cable.

If longer cables are required, a cable with lower attenuation and/or DCresistance should be used. Table 2-1 provides details regarding some popularcables such as the RG 58 and RG 213. If the spectral environment is pollutedwith noise in the 440 MHz band, it is recommended to use a higher quality

double-shielded cable such as the LMR 240 or LMR 400 (manufactured byTimes Communications).

Table 2-1. IF Cables

Cable Type RG 58 RG 213 LMR 240 LMR 400

Maximum cableLength (m)

30 100 65 150

• The Indoor unit should be installed in as close as possible to the building’sentry point of the IF cable. The location of the Indoor unit should also takeinto account the need to connect it to a power mains outlet and to the CPE.

Note: Outdoor units and antennas should be installed ONLY by experiencedinstallation professionals who are familiar with local building and safetycodes and, wherever applicable, are licensed by the appropriate governmentregulatory authorities.

The system complies with the ETS 300 385 standard and is protectedagainst secondary lightning strikes when its outdoor unit is properlygrounded according to the applicable country-specific industry standardsfor protection of structures against lightning. The system complies with EN61000-4-5, test level 3 (2kV).

Failure to do so may void the BreezeACCESS product warranty and mayexpose the end user or the service provider to legal and financial liabilities.BreezeCOM and its resellers or distributors are not liable for injury,damage or violation of regulations associated with the installation ofoutdoor units or antennas.

Aligning the Antenna


4. ALIGNING THE ANTENNA

Note: Antenna alignment using the RSSI bar display is possible only after theAccess Unit you wish to associate with is operational and the basicparameters were properly configured (see Section 3.2). Otherwise, the unitwill not be able to synchronize and associate with the Access Unit. As theRSSI measurement is performed on received frames, its results aremeaningless as long as the unit is not associated with an AU.

1. Verify that the Power indication (the Yellow LED of the BSSI bar display)is ON.

2. Align the antenna (integrated into the front side of the SU-RA Outdoor unit,or separate if the unit is an SU-RE) to point towards the general direction ofthe base station.

3. The RSSI bar display is located on the bottom panel of the Outdoor unit(refer to Figure 2-6). The eight green RSSI LEDs are used for reading theReceived Signal Strength Indication. The higher the number of green LEDsthat are ON, the higher the level of the received signal. Rotate the antennaleft and/or right until you reach the point of maximum RSSI reading. Makesure that at all times, the front of the antenna faces the general direction ofthe base station.

4. For proper operation, at least one green LED should be ON. If you cannotreach a point where at least one green LED is ON, try to improve thereception quality by placing the antenna at a higher point or in a differentlocation.

Note: In some cases (e.g., when the Subscriber Unit is very close to the BaseStation), the antenna might have to be installed at an appropriate angle, inorder to ensure that it is directed towards the Base Station antenna).

5. Tighten the bracket screws (or the U-bolts/metal band), firmly securing theunit or the antenna to the pole.

Appendix B. Basic Parameters


APPENDIX B. BASIC PARAMETERS

IP Parameters Common to all Product Families

The following Air Interface parameters are relevant to all BreezeACCESSproducts.

• IP Address – Displays the current IP address of the unit and allows entryof a new IP address (4 x 3 digit octets, separated by dots). The default IPAddress is 010.000.000.001.

• Subnet Mask – Displays the current subnet mask of the unit and allowsentry of a new subnet mask (4 x 3 digit octets, separated by dots). Thedefault mask is 255.000.000.000.

• Default Gateway Address – Displays the current address of the defaultgateway of the unit and allows entry of a new default gateway address(4 x 3 digit octets, separated by dots). The default gateway address is000.000.000.000.

• DHCP Client

⇒ DHCP Options – Displays the current status of the DHCP (DynamicHost Configuration Protocol) support, and allows selecting a newoperation mode. The available options are:

∗ Disable – Use manual procedure for configuring the IPparameters.

∗ DHCP Only – Search for a DHCP Server and obtain the IPparameters from it (IP Address, Subnet Mask and DefaultGateway Address).

∗ Automatic – Search for a DHCP Server for configuration ofthe IP parameters. If a DHCP Server is not found withinapproximately 40 seconds, use the currently configured IPparameters.

The default is Disable.



⇒ Access to DHCP - To define the port through which the unit isallowed to communicate with a DHCP server. The options are thefollowing:

∗ From Wlan Only

∗ From Ethernet Only

∗ From Both Ethernet & Wlan

The default for an Access Unit is From Ethernet Only. Thedefault for a Subscriber Unit is From Wlan Only.

Air Interface Parameters Common to all ProductFamilies

The following Air Interface parameters are relevant to all BreezeACCESSproducts.

• ESS ID – The ESSID (Extended Service Set ID) of the unit (up to 32 printableASCII characters). The ESSID is a string used to identify a wireless network. Itprevents the unintentional merging of two co-located wireless networks. AnSU can only associate with an AU that has an identical ESSID. Use differentESSIDs to segment the wireless access network and add security to yournetwork. The default value is ESSID1.

Note: The ESSID string is case-sensitive.

• Maximum Data Rate – Displays the current maximum data rate, andallows entry of a new value for the maximum data rate.

BreezeACCESS units operate at 1 Mbps, 2 Mbps or 3 Mbps. Under certainconditions (compatibility reasons or range/speed trade-off), you maydecide to limit the use of higher rates. If the quality of the link is not goodenough, it is recommended to decrease the value of these parameters (thehigher the date rate, the higher the error rate). Otherwise, there is a highprobability that the unit will have to retransmit many frames several timesbefore temporarily reducing the data rate. A high number ofretransmissions reduces the overall throughput for the selected SU as wellas for all the other SUs served by the same AU.



The link quality can be estimated based on the RSSI measurement usingthe Continuous Link Quality Display in the SU. If the measured RSSI isless than a certain threshold, it is recommended to decrease the MaximumData Rate of the SU in accordance with the following table:

Recommended MaximumData Rate

3Mbps 2Mbps 1Mbps

BreezeACCESS II, SU-A/E RSSS>111 100<RSSI<111 RSSI<100

BreezeACCESS XL SU-A/E RSSI>108 97<RSSI<108 RSSI<97

BreezeACCESS MMDS SU-A/E RSSI>108 97<RSSI<108 RSSI<97

The default value is 3 Mbps (with the exception of BreezeACCESS3.8GHz SUs that have a default value of 1Mbps). Allowed values are 1, 2or 3 Mbps.

The AU learns the Maximum Data Rate used by each SU during theassociation process, and uses this rate for transmissions to the specific SU.

Parameters Specific for BreezeACCESS XL

The following air interface parameters are only relevant to BreezeACCESS XLproducts.

There are two different ways to define the hopping frequencies to be used:

a) Using the Hopping Band and Frequency Offset Parameters.

b) Using the Flexible Hopping Definition menu.

The Hopping band and Hopping Offset parameters are only applicable forapplications that use a 2MHz channel spacing and one of the standardbandwidths available in the Hopping Band menu.

If the defined Channel Spacing is not 2MHz, you should change the value of theChannel Spacing parameter in the Flexible Hopping Definition menu to 2MHz,in order to have access to the full Hopping Band menu. Alternatively, you maycontinue defining the required sub-bands in the Flexible Hopping Definition



menu, as any band that can be defined using the Hopping Band and FrequencyOffset parameters may also be defined by the Define Sub-bands option in theFlexible Hopping Definition menu).

For other channel spacing values, or for hopping bands/frequency configurationsthat are not supported by the standard Hopping Band values, use FlexibleHopping Definition as described on page 39.

• Hopping Band – Displays the current bandwidth and allows entry of a newbandwidth. The bandwidth is determined according to specific conditionsrelated to the license to use a given frequency band, and according to otherconsiderations. The available selections are 10, 12, 14, 24, 28, 36, 42 and 50MHz (Some selections are not available in models with a total availableband width lower than 50 MHz). In addition, Single Channel and FlexibleHopping Definition selections are also available. The default selection (witha Channel Spacing of 2MHz) is 12MHz.

Note: The full Hopping Band menu is only available with a Channel Spacingof 2MHz. In products that support additional Channel Spacing values,if the selected Channel Spacing is different from 2MHz, only theFlexible Hopping Definition will be available in the Hopping Bandmenu and all other options are not available. The Channel Spacingparameter in the Flexible Hopping Definition menu must be changed to2MHz to enable all the applicable options in the Hopping Band menu.

• Frequency Offset – Displays the current offset of the Hopping Band fromthe beginning of the available frequency range, and allows entry of a newoffset. The offset is measured in channels, where each channel is 2 MHz.For example, in products operating in the 3.5a band (3.410-3.452 GHzuplink), a Frequency Offset of 5 (10 MHz) will cause the hopping band tostart at 3.420 GHz for the uplink and at 3.520 GHz for the downlink. Themaximum value of the Frequency Offset is determined by the overallavailable bandwidth and the selected Hopping Band (Hopping Band shouldbe selected before selecting the Frequency Offset).

The default Frequency Offset is 0.

When setting this parameter, consider the following relationship:Max. Frequency Offset (channels) = (Overall Bandwidth-Hopping Band)/2.For example, in products operating in the 3.5a band with an overall



bandwidth of 42 MHz, if the selected Hopping Band is 12 MHz then theallowed range for Frequency Offset is from 0 to 15 channels.

Notes: In Single Channel mode, using the minimum (0) and the maximumvalues of the Frequency Offset parameter will result in transmitting atthe edges of the band without using any guard band.

The Frequency Offset parameter does not have any effect on theFlexible Hopping mode.

• Flexible Hopping Definition– Allows defining the sub-bands to be used;displays the selected sub-bands, the hopping frequencies that will be used asa result of these selections and the current hopping sequence (based on theprevious selections made before the last Reset). The new settings will gointo effect only after the next Reset.

Note: The algorithm that determines the operational hopping sequence (theactual hopping sequence based on rearranging the order of the selectedhopping frequencies) when using Flexible Hopping Definition isdifferent than the one used when fixed Hopping Bands are selected,even when the selected set of hopping frequencies is the same.Therefore, all units in the same base station (all AUs and associatedSUs) must use the same hopping frequencies selection method (fixedHopping Band or Flexible Hopping Definition).

The Flexible Hopping mode is intended primarily for use in cases where theoperating band cannot be defined by the Hopping Band and FrequencyOffset parameters. This includes the following instances:

⇒ When the bandwidth of the operating band is different from the standardbands available in the Hopping Band menu.

⇒ When the operating band is comprised of two or more non-continuousbands.

⇒ When the required Channel Spacing is other than 2MHz.



The Flexible Hopping menu includes the following options:

⇒ Channel Spacing – Allows defining a new value for the ChannelSpacing parameter, if the unit supports selection between severalchannel spacing values. Some models may support only a single valuefor the Channel Spacing parameter, in which case this parameter is notavailable. The Channel Spacing parameter defines the minimumdistance between consecutive hopping frequencies. In addition, theChannel Spacing parameter also determines the guard band, which is thedistance of the first hopping frequency in each sub-band from thebeginning of the sub-band, as well as the minimum distance of the lasthopping frequency in each sub-band from the end of the sub-band.

Channel Spacing Guard Band

1MHz 1MHz

1.75MHz 0.75MHz

2MHz 1MHz

The available selections in products that support all the options are 1,1.75 and 2MHz. In some products only a subset of these options may beavailable. The default is 2MHz.

Note: Changing the value of the Channel Spacing will erase the currentlist of defined Sub-bands/frequencies

⇒ Define Sub-bands – Allows defining a new list of sub-bands and/ordiscrete frequencies. Enter a list of the required sub-bands and/orfrequencies, using either sub-bands (f1-f2) or discrete frequencies, e.g.3410-3418,3425,3430-3434. The frequencies (either the start and stopfrequencies of a sub-band or discrete frequencies) can be in thefollowing formats:

∗ MHz Resolution, e.g. 3420

∗ kHz resolution, e.g. 3430.250, 3445.500, 3412.000 (you must enter3 digits after the dot)

When using a Channel Spacing of 1 or 2 MHz, the entries should be ona 1MHz grid (e.g. 3410, 3413).



When using Channel Spacing of 1.75MHz, the usable frequencies are ona grid of 0.250MHz, the first one being at a distance of 0.750MHz fromthe beginning of the radio band. Therefore, for products using the 3.5aband, the usable frequencies (uplink) are 3410.750, 3411.000,3411.250……

This is also the list of valid entries for discrete frequencies. Whendefining sub-bands, the entries must be on a grid of 0.250MHz thatstarts at the beginning of the radio band. Therefore, for products usingthe 3.5a band, the list of valid entries for defining discrete frequencies aswell as sub-bands’ start and end frequencies, is 3410, 3410.250,3410.500…….

Use a comma to separate between entries. Use a hyphen to define sub-bands (no spaces).

When a discrete frequency is defined, it is the actual hopping frequencyto be used. When a sub-band is defined, the hopping frequencies aredetermined by the value of the Channel Spacing parameter (see ChannelSpacing above).

Note: Channel Spacing parameter should be configured prior to defininga new set of sub-bands.

The entries are frequencies in the lower radio band (uplink frequencies,except for 3.8GHz products where the downlink frequencies should beused).

The following are invalid combinations and will be rejected:

∗ Two overlapping sub-bands, e.g. 3410-3420,3418-3422.

∗ Combinations trying to force a distance between channels smallerthan the Channel Spacing, e.g. 3420.500, 3421.000(with aChannel Spacing of 1.75MHz).

Examples:

∗ The selected sub-band is 3419-3431MHz. The Channel Spacing is2MHz. The hopping frequencies are: 3420, 3422, 3424, 3426, 3428and 3430MHz. (6 frequencies)



∗ The selected sub-band is 3419-3431MHz. The Channel Spacing is1MHz. The hopping frequencies will be: 3420, 3421, 3422, 3423,3424, 3425, 3426, 3427, 3428, 3429 and 3430MHz (11 frequencies)

∗ The selected sub-band is 3419-3430MHz. The Channel Spacing is1.75MHz. The hopping frequencies will be 3419.750, 3421.500,3423.250, 3425.000, 3426.750 and 3428.500 (6 frequencies). Notethat the actual used band (including the o.750MHz guard bands) isonly 3419-3429.250MHz.

Note: The hopping frequencies are calculated for each sub-bandseparately. Therefore, the hopping frequencies calculated fortwo consecutive sub-bands may differ from the hoppingfrequency calculated for a single “combined” band (e.g. theresult for the entries 3410-3420,3420-3420 may differ from theresults for the entry 3410-3430).

⇒ Show Flexible Hopping Parameters – Allows viewing the followinginformation:

∗ Sub-bands – An updated list of the defined sub-bands to becomeeffective after the next Reset. The displayed sub-band includes theguard bands from the first and last hopping frequency in the sub-band. .

∗ Hopping Frequencies – An updated list of all the hoppingfrequencies (lower band-uplink frequencies for all products exceptBreezeACCESS 3.8GHz) to be used after the next Reset.

Enter a list of frequencies and/or frequency ranges tobe added, e.g. 2501.500,2407.500-2519.500, 2525.500.Use a comma toseparate between entries (no spaces). The allowed entries are from 2500to 2688 in steps of 0.5MHz. The frequencies (either the start and stopfrequencies of a range or discrete frequencies) can be in the followingformats:

MHz Resolution, e.g. 2520

kHz resolution, e.g. 2501.000,2505.500 (you must enter 3 digits after thedot).

The minimal channel spacing between frequencies is 3MHz. Whenentering a range, this will be the default channel spacing (e.g. for therange 2510-2516 the hopping frequencies will be 2510, 2513 and 2516MHz).

It is recommended to use the standard MMDS frequencies. SeeAppendix C for a list of the standard MMDS frequencies.

Note: Note: According to the FCC rules 15.247 (3), when operating theequipment in a multi-point system the RF output power must be adjustedaccording the gain of the antenna to limit the EIRP to a maximum of 36dBm. Refer to Table D-2 on the next page for details on requiredadjustment, when using the HP (High Power) models with 26 dBm poweroutput at the antenna port.

Use the Transmit Power Control parameter to change the gain of the Tx powercircuits as required. A value of 15 represents the highest transmit power level.A lower value represents a lower transmit power level. The allowed range isfrom 0 to 15. The default value is 15 (maximum power). The effect of thisparameter on the transmitted power is not linear. In addition, it is affected by thelength (attenuation) of the IF cable.

Table D-3 on the next page displays transmit power control parameters valuesrequired to decrease the transmitted power by approximately 5 dB, 10 dB and 15dB as a function of cable length (refers to RG-58).

Use the factors in Table D-4 to calculate the applicable values of the TransmitPower Control parameter for other cable types, as a function of the cable length.For example, a 40 m long RG 213 cable is equivalent to a 40/2.2 = 18 m long RG58 cable.
