New Features in the DS 11 Ver 4

1010

What is the BreezeNET DS 11 ver 4

• A new generation of the existing DS 11 Ver 3

• Includes both hardware and software changes

Main areas of improvement in Ver 4 (compared to Ver 3):

Security

Performance

Ease of installation and Maintenance

1111

Ver 4 – Added Security Features• MAC Address Association Control (BU feature)

• A list of MAC addresses in the BU that are allowed to be associated with it (Default: all)

• WEP Key Length of 64 or 128 (both for BU and RB)

• 128 bit key allows for better security

• 64 bit key allows communication with remotes that have 64 bits WEP only (Default: 64)

• Unicast Relaying and Broadcast Relaying (BU only)

• Control of Broadcast and Unicast relaying • When enabled, the BU will transmit back into the sector messages from

RBs in the sector that are destined to RBs in the same sector (default: Enable).

• ESSID “ANY” option control (BU feature)

• A BU feature to allow/Disallow association with units that use “ANY” for the ESSID (Default: disable)

• Proprietary scrambling of data (both for BU and RB)

• Extra security measure, proprietary to DS11 (Default: disable)

• Independent of the WEP

Ver 4 – Performance Enhancing Features

• Preamble length (both for BU and RB)

• Selection between “Long” or “Short” Preamble

• Increase throughput in “Short Preamble”

• Use it always unless you must support “Long Preamble only” units (Default: Long)

• “Best BU” and “Preferred BU” (RB feature)

• Best BU: scan the area and choose the BU with the best RSSI (Default: enable)

• Preferred BU: associate only with the BU that is marked as the preferred one (Default: None).

Maximum net data rate of the DS 11 Ver 4 is 6.2 Mbps

Ver 4 – Performance Enhancement (cont.)• Automatic dissociation of RB (BU feature)

• While BU is disconnected from the Ethernet dissociate all RBs and do not associate any RB

• Used to obtain BU redundancyobtain BU redundancy

• Ethernet Backoff Control (both for BU and RB)• On detecting a collision a station will wait a locally

determined period of time before attempting re-transmission

• The “disable” option is useful in PTPuseful in PTP to increase Ethernet efficiency due to low collision probability - no need to wait after collision (Default: Disable)

• Reject/Forward Unknown (both for BU and RB)• Reject /Forward frames whose destination addresses

are not recognized by the bridge – More efficient Air More efficient Air interface interface (Default: Forward)

Ver 4 – Easy Installation and Maintenance

• Automatic ConfigurationSingle Button Configuration of Common Modes:

PTP ModeCW=15, RTS threshold=2437

PTMP ModeCW=63, RTS threshold=2437 in BU and 60 in RB

Compatibility modeRate=2Mbps, Short Preamble=disable, Scrambling=disable

High Performance ModeRate=11Mbps, Short Preamble=Enable (in BU only)

1616

Easy Software Upgrade

• One click upgrade of multiple units firmware

• Always keeps (last) SW version in flash memory

• Automatic fallback to previous version when required

• Progress indicator bar

• Acknowledgment from every unit

• Flash Memory

contains two last versions (both for BU and RB). Current and last versions are kept in memory allowing regression to previous version.

Compatibility

• Backward compatibility• The DS 11 Ver 4 units are backward compatible with the Ver 3

product• When Ver 3 and Ver 4 units are mixed in one location only Ver 3

features are supported

• Upgrade ability• DS 11 Ver 4 includes hardware changes and therefore a Software

Upgrade is not applicable
