New Features in the DS 11 Ver 4

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
10
Ver 4 – Added Security Features
•
MAC Address Association Control (BU feature)
•
•
•
•
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
11
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 list of MAC addresses in the BU that are allowed to be associated
with it (Default: all)
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
Router
BU
RBs
Multi Layer Security Platform
Proprietary Scrambling of Data
128 bits WEP key (802.11b)

and Relay Traffic Control

12
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
13
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 redundancy
RB1
BU2
x BU1
Ethernet Backoff Control (both for BU and RB)
•
•
On detecting a collision a station will wait a locally
determined period of time before attempting retransmission
BU
The “disable” option is useful in PTP to increase
Ethernet efficiency due to low collision probability - no
need to wait after collision (Default: Disable)
Detecting
Reject/Forward Unknown (both for BU and RB)
•
14
Reject /Forward frames whose destination addresses
are not recognized by the bridge – More efficient Air
interface (Default: Forward)

Ver 4 – Easy Installation and Maintenance
•
Automatic Configuration
Single Button Configuration of Common Modes:
 PTP Mode
CW=15, RTS threshold=2437
 PTMP Mode
CW=63, RTS threshold=2437 in BU and 60 in RB
 Compatibility mode
Rate=2Mbps, Short Preamble=disable, Scrambling=disable
 High Performance Mode
Rate=11Mbps, Short Preamble=Enable (in BU only)
15
Easy Software Upgrade
•
Flash Memory
contains two last versions (both for BU and RB). Current and last versions are
kept in memory allowing regression to previous version.
16
•
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
Ease of Installation and Management
Installation
•
•
•
•
•
Easily manageable CAT-5 Input/Output cable
110/220 universal power supply
RSSI Led Bar for antenna alignment
Extensive LED diagnostics in both indoor and
outdoor units
“Back to Factory Default” Reset button
Management
•
•
•
•
17
User friendly Configuration Utility
Remote management using SNMP
A range of counters for diagnostics
Per link statistics in the BU
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
