RADWIN 2000 C-series support asymmetric ETH throughput up to 200 Mbps Aggregate
The capacity allocation between uplink and downlink traffic is determined
automatically according to actual Ethernet traffic and air interface conditions
User settings determine the uplink / downlink capacity in cases of congestion

Asymmetric Ethernet (C Series)
100% 0

50.0% / 50.0%
Transmission Ratio
With TDM services enabled, the link provides symmetrical throughput up to 100
Mbps full duplex
For HSS installations the uplink / downlink capacity ratio will be fixed (i.e. will not
change automatically) according to the HSS Master configuration
The MIR (Maximum Information Rate ) may be set up to 100 Mbps per direction

In this mode, RADWIN 2000 estimates Ethernet throughput by filling frames over the air to maximum for 30 seconds
Activating this process does not affect service

1. At the main menu, click Maintenance and then click on Estimated Eth. Throughput
2. A confirmation dialog window will appear
3. Click Yes to continue
4. The Ethernet Services & Estimated Throughput window is displayed
5. At the end of 30 seconds, the display reverts to normal

The figures in the graphs relate to the maximum achievable throughput
The Manager considers each side of the link as if it was accommodating the
whole aggregate capacity
When HSS is enabled, the display will show 50% of the maximum available
throughput:
e.g. with RADWIN 2000 C-Series, 40 MHz, we shall see 100Mbps on each side
When HSS is disabled, the Manager will show maximum ratios for each end.
e.g. - with RADWIN 2000 C-Series, 40 MHz, we shall see 198.4Mbps on each
side
Layer 2 Ethernet
RADWIN supports two classification
criteria: 802.1p and DiffServ
Frames towards the air-interface are
mapped into one of 4 Queues (real time, near real time, controlled load, best effort)
according to the classification criteria
Frames are pulled (scheduled) from the
queues toward the air interface
according to priority and a weighted
mechanism

QoS
Each queue has configurable weight which
is a percentage out of the total link capacity
The user can limit the Maximum
Information Rate (MIR) of each priority
queue
The queue MIR cannot exceed the link MIR
With QoS disabled, all traffic is handled
with the same priority

Hub Synchronization System(s)
Unique burst synchronization technique
Synchronizes Tx and Rx timing for all
units at a hub site
Eliminates collocation TDD interference
Enables multi point-to-point
architecture
RADWIN Training Center 31
Hub Synchronization System (HSS)
Hub Sync Master - The Hub Sync Master (HSM) generates the pulses that synchronize the timing of
the Hub Sync Clients (HSC).
Hub Sync Client Continue Transmission In the event that the unit loses synchronization with the Hub Sync Master, the link
remains active.
Hub Sync ClientDisable Transmission In the event that the unit loses synchronization with the Hub Sync Master, the link
is dropped until the synchronization pulses resume. This setting prevents the unit
from causing interference.
RADWIN Training Center 32
HSS Architecture
HSS Limitations
Use HSS cable (not IDU-ODU) cable.
Sum of all HSS cables
External interferences in collocated environment
Verify a physical separation of minimum 3 meters (use the Maximum) between a RADWIN unit and any other collocated radio unit on the site
Use the maximum frequency gap between the units
Use the quality bar in the bottom to select the best frequency channel as clear as possible from interferences (changing band is recommended)
Install the collected links with different polarization between them
Decrease the Tx power of a link in order to minimize the collocated interferences (Use the LBC to check if possible)
RADWIN Training Center 34
GPS Synchronization System (GSS)
Collocated ODUs are synced using HSS to avoid
mutual interference
Sync between hub sites is required in dense
and large scale networks
Synchronization between sites is enabled
using GPS timing
Reduces overall network interference
Improve capacity, spectrum efficiency and
deployment flexibility
RADWIN Training Center 35
The GSU receives a synch signal from the GPS once per
second
It acts as a HSM unit
The GSU is connected to the HSS Unit using a standard
HSS cable. It synchronizes the transmission timing of
multiple Hub-Sites to the same clock source thus
eliminating mutual interference
When the GSU doesnt receive a synchronization signal
from the GPS for 30 seconds, it moves automatically to
Self-Generation mode and acts as a regular HSM unit,
until the GPS recovers
