Chapter 4 - Operation and Administration Burst Mode Burst mode provides an increased throughput by reducing the overhead associated with transmissions in the wireless media. In a burst transmission the inter-frame spacing is reduced and data frames are transmitted without any contention period. Burst Mode Option The Burst Mode Option enables or disables the Burst Mode operation. The default is Enable.
Menus and Parameters A. Each new frame (first transmission attempt) will be transmitted at a modulation level selected by the Adaptive Modulation algorithm. B. If first transmission trial has failed, the frame will be retransmitted at the same modulation level up to the maximum number of retransmission attempts defined by the Number of HW Retries parameter. C. If the frame was not acknowledged and the Software Retry Support option is disabled, the frame will be dropped.
Chapter 4 - Operation and Administration Number of SW Retries The Number of SW Retries parameter defines the maximum number of times to use the software Retrial mechanism when the Software Retry Support option is enabled. The available values range from 0 to 14. The default value is 3.
Menus and Parameters Service Parameters (RB Only) The Service Parameters menu enables defining user filtering parameters. The Service Parameters menu is only available to RBs and includes the following parameters: User Filtering Parameters The User Filtering Parameters submenu enables defining the IP addresses of user devices authorized to access the wireless media for security and/or control purposes. In addition, it can be used to enable the transmission and reception of specific protocol frames.
Chapter 4 - Operation and Administration Set User Filter Range The Set User Filter Range option enables defining a range of addresses for each of the User Filter IP Address entries. The range includes the base address. Available values range from 0 to 255. The default value is 0 (not used). NOTE You can enter either a mask or range, but not both, to define a group of user filter addresses. If the range is other than 0, than the mask is ignored.
Menus and Parameters Security Parameters BreezeNET B can support encryption of authentication messages and/or data frames using one of two encryption standards: WEP Wireless Equivalent Privacy algorithm. WEP is defined in the IEEE 802.11 Wireless LAN standard and is based on the RSA’s RC4 encryption algorithm. AES Advanced Encryption Standard. AES is defined by the National Institute of Standards and Technology (NIST) and is based on Rijndael block cipher.
Chapter 4 - Operation and Administration Data Encryption Mode The Data Encryption Mode option allows enabling or disabling data encryption. When enabled, all data frames are encrypted. The default is Disable. NOTE The BU and the RB it serves should be configured to the same Data Encryption Mode option. Security Mode The Security Mode option enables selecting the algorithm to be used for encrypting the authentication messages and/or data frames. The available options are WEP and AES. The default is WEP.
Menus and Parameters Promiscuous Authentication (BU only) The Promiscuous Authentication mode enables a new RB to become associated with a BU where Shared Key operation and/or Data Encryption is used, even if this RB does not have the correct security parameters. After the RB is associated it should be remotely configured with the proper parameters (or upgraded). Once the RB is configured properly, the Promiscuous Mode should be disabled. The default is Disable.
