2.4.3.1 Transmit Power Table

The Transmit Power Table includes the following read-only components for each of the applicable modulation levels:

Max Tx Power Range: The range available for the applicable Tx Power parameter.

In AU, the range is defined by the hardware of the unit. In some cases the upper boundary may be limited by the Maximum Tx Power as defined in the

Sub-Band, and/or by the Max EIRP as defined in the Sub-Band together with the Antenna Gain parameter.

In SU the maximum value is determined by the value of the applicable Max

Tx Power entry in the Maximum Transmit Power Table.

Tx Power: The functionality differs between AU and SU:

In AU: The transmit power in dBm defined for the applicable modulation level.

In SU: If ATPC is disabled, this is the transmit power in dBm defined for the applicable modulation level. If ATPC is enabled, it serves as the initial transmit power in dBm for the ATPC algorithm.

The value of Tx Power for Modulation Level 1 to 5 is set by the Transmit

Power parameter (below the table). For other modulation levels, the Tx Power is set to the minimum between the value of the Transmit Power parameter and the maximum Tx power allowed by the HW and the Country Code for the specific modulation level.

Current Tx Power (Applicable in SU only, NA in AU): The actual transmit power in dBm for the applicable modulation level.

2.4.3.2 Maximum Transmit Power Table (SU only)

The Maximum Transmit Power Table includes the following read-only components for each of the applicable modulation levels:

Defined Max Tx Power Range: The range available for the applicable Max Tx

Power parameter. The range is defined by the hardware of the unit. In some cases the upper limit may be limited by the Maximum Tx Power as defined in the Sub-Band, and/or by the Max EIRP as defined in the Sub-Band together with the Antenna Gain parameter.

Max Tx Power: The maximum level of the Tx Power. The value for Modulation

Level 1 to 5 is set by Maximum Tx Power parameter (below the table). For other modulation levels, the Max Tx Power is set to the minimum between the

BreezeCONFIG for BreezeACCESS VL and BreezeACCES 4900 User Manual

Air Interface Parameters value of the Maximum Tx Power parameter and the maximum Tx power allowed by the HW and the Country Code for the specific modulation level.

This parameter also sets the upper boundary for the applicable Max Tx Power

Range entry in the Transmit Power Table. It also sets the maximum level for the ATPC algorithm. The value of Max Tx Power cannot be higher than the current value of the applicable Tx Power entry in the Transmit Power Table.

In the AU, the Transmit Power parameter defines the fixed transmit power level and is not part of the ATPC algorithm.

In the SU, the Transmit Power parameter defines the fixed transmit power level when the ATPC algorithm is disabled. If the ATPC Option is enabled, the value configured for this parameter serves for setting the initial value to be used by the

ATPC algorithm after either power up or losing synchronization with the AU.

The minimum value for the Transmit Power Parameter is –10 dBm (the ATPC may reduce the actual transmit power of the SU to lower values). The maximum value of the Transmit Power Parameter depends on several unit properties and parameters: The HW revision of the unit, the Maximum Allowed Tx Power as defined for the applicable Sub-Band, and the Maximum EIRP as defined for the applicable Sub-Band, together with the value of the Antenna Gain. In the SU, it cannot be higher than the Maximum Tx Power parameter.

For each modulation level, the unit will use as Tx Power (see Transmit Power table) the minimum between this parameter and the maximum Tx power allowed by the HW and the Country Code for the specific modulation level.

2.4.3.4 Maximum Tx Power (SU only)

The Maximum Tx Power parameter limits the maximum transmit power that can be reached by the ATPC algorithm. It also sets the upper limits for the Transmit

Power parameters.

The minimum value for the Maximum Tx Power is -10 dBm. The maximum value depends on several unit properties and parameters: The HW revision of the unit, the Maximum Allowed Tx Power as defined for the applicable Sub-Band, and the

Maximum EIRP as defined for the applicable Sub-Band, together with the value of the Antenna Gain.

For each modulation level, the unit will use as Max Tx Power (see Maximum

Transmit Power table) the minimum between this parameter and the maximum

Tx power allowed by the HW and the Country Code for the specific modulation level.

63, 127, 255, 511 and 1023.

RTS Threshold: The minimum frame size that requires an RTS/CTS (Request

To Send/Clear To Send) handshake. Frames smaller than the defined value are transmitted directly to the wireless link without the preceding RTS frames.

The available values range from 20 to 4032 bytes. 4032 means that the

RTS/CTS mechanism is never used.

NOTE

In units with HW revision B or lower running SW Version 3.0 and higher the range is 20 to 2200. In units with HW revision C running SW Version 3.0 the range is 20 to 3400. In all units running SW

Version lower than 3.0 the range is 20 to 1600.

Number of Hardware Retries: The maximum number of trials to transmit an unacknowledged frame in each Hardware Retrials phase. The available values range from 1 to 14.

NOTE

The Number of HW Retries parameter is not applicable when the Wireless Link Prioritization Option is enabled.

Avg SNR Memory Factor: The SNR Memory Factor defines the weight of history (value of last calculated average SNR) in the formula used for calculating the current average SNR for received data frames. This average

SNR is used by the ATPC algorithm in the AU and is also included in the

Adaptive Modulation information messages transmitted by the AU and the SU.

The higher the value of this parameter, the higher is the weight of history in the formula.

Available values: -1 to 32. -1 is for no weight for history, meaning that average

SNR equals the last measured SNR.

Maximum Modulation Level: If the Adaptive Modulation algorithm is enabled, it sets the maximum modulation level that can be reached by the

BreezeCONFIG for BreezeACCESS VL and BreezeACCES 4900 User Manual

Performance Parameters algorithm. If the Adaptive Modulation algorithm is disabled, it sets the fixed modulation level to be used.

Multicast Modulation Level (AU only): The modulation level for transmission of multicast and broadcast data frames. Since multicast and broadcast transmissions are not acknowledged, it is recommended to set a low modulation level to ensure transmission without error.

Burst Mode Option: From the dropdown menu, select whether to Enable or

Disable the Burst Mode operation. Burst mode provides an increased throughput by reducing the overhead associated with transmissions in the wireless medium.

NOTE

The Burst Mode parameters are not applicable when the Wireless Link Prioritization Option is enabled.

Burst Interval: The Burst Interval defines the burst size, which is the time in which data frames are sent immediately without contending for the wireless medium. The available values depend on the Sub-Band (Country Code).

Concatenation Option: The Concatenation Option enables or disables the packet concatenation mechanism.

Maximum Concatenated Frame Size: The Maximum Concatenated Frame

Size parameter defines the maximum size (in bytes) for a concatenated frame.

The range is:

256 to 2200 bytes for units with HW revision A or B.

256 to 4032 bytes for units with HW revision C or higher.

Adaptive Modulation Decision Thresholds: Enables selection between

Normal and High decision thresholds for the Adaptive Modulation algorithm.

In links with a low SNR (below 13), the Adaptive Modulation algorithm may not stabilize on the correct modulation level when using the standard decision thresholds. In this case the algorithm may try to use a modulation level that is too high, resulting in a relatively large number of dropped frames. The

“High” option solves this limitation and ensures good performance also in links with a low SNR.

2.9.2 Traffic Priority Tab

Service Parameters

Figure 2-30: Traffic Priority Tab

Each packet that is received from the Ethernet port is placed in either the High or

Low queue, according to the Traffic Prioritization parameters. When the MIR/CIR mechanism decides that a packet must be sent, the High priority queue will be checked first. If the High priority queue is not empty, the first element in the queue is forwarded to the MIR/CIR mechanism. Packets from the Low priority queue will be forwarded only if the High queue is empty.

The prioritization of the packets is done using different classifiers:

VLAN Priority

ToS Priority: IP Precedence or DSCP

UDP and/or TCP ports

Each one of these classifiers can be activated/deactivated. If more than one classifier is activated, the priority of each packet will be determined by the highest priority given to it by the active classifiers.

The Traffic Prioritization parameters enable activating/deactivating each of these classifiers, and configuring the applicable parameters for each classifier.

The Traffic Prioritization parameters include:

BreezeCONFIG for BreezeACCESS VL and BreezeACCES 4900 User Manual

Chapter 2-Unit Configuration

VLAN Priority Threshold: The VLAN Priority Threshold is applicable for

Trunk and Hybrid Links only. It enables defining the value of the VLAN

Priority Threshold. If the VLAN Priority field in a tagged frame is higher than the value of the VLAN Priority Threshold parameter, the packet will be routed to the High queue. If the VLAN Priority field is lower than or equal to this value, the packet will be transferred to the Low queue (unless it is assigned a

High priority by another classifier).

Valid values range from 0 to 7. A value of 7 (the default) means that all packets get a low priority (equivalent to disabling the VLAN-based classifier).

ToS Prioritization Option: The ToS Prioritization Option defines whether

ToS-based prioritization is enabled or disabled. The following options are available:

Disable

IP Precedence (RFC791 based prioritization)

DSCP (RFC2474 based prioritization)

IP Precedence Threshold: The IP Precedence Threshold parameter is applicable when the ToS Prioritization Option is set to IP Precedence. If the value of the 3 IP Precedence bits in the IP header is higher than this threshold, the packet is routed to the High queue. If the value is lower than or equal to this threshold, the packet will be transferred to the Low queue

(unless it is assigned a High priority by another classifier).

Valid values range from 0 to 7. A value of 7 (the default) means that all packets get a low priority (equivalent to disabling the IP Precedence-based classifier).

DSCP Threshold: The DSCP Threshold parameter is applicable when the ToS

Prioritization Option is set to Enable DSCP (RFC2474) Prioritization. If the value of the 6 DSCP bits in the IP header is higher than this threshold, the packet is routed to the High queue. If the value is lower than or equal to this threshold, the packet will be routed to the Low queue (unless it is assigned a

High priority by another classifier).

Valid values range from 0 to 63. A value of 63 (the default) means that all packets get a low priority (equivalent to disabling the IP Precedence-based classifier).

2.9.2.2 UDP Port Ranges/TCP Port Ranges

The UDP/TCP Port Ranges parameters allow defining port ranges to be used as priority classifiers when the UDP/TCP Port Ranges Prioritization is set to enable the applicable port-based classification. All relevant packets whose destination is included in the list will be routed to the High queue. All other packets will be routed to the Low queue (unless they were assigned a High priority by another classifier).

The UDP/TCP Port Range parameters include:

RTP/RTCP Prioritization: Voice over IP is transported using Real Time

Protocol (RTP). The Real Time Control Protocol (RTCP) is used to control the

RTP. When an application uses RTP/RTCP, it chooses for destination ports consecutive numbers: RTP port is always an even number, and the port with the odd number following it will be assigned to RTCP.

If the administrator selects to prioritize only the RTP packets, then all the packets with an odd numbered destination port will always have Low priority.

The packets with an even number for destination port will receive High priority, if the port number is included in the specified ranges.

If the administrator selects to prioritize both RTP and RTCP packets, then all packets whose destination port number is included in the specified ranges will receive High priority.

The available options are:

RTP and RTCP

RTP Only
