Wi-Fi in a Nutshell
Wi-Fi was originally designed for Wireless connectivity between a single
Access Point (AP) and multiple clients
Wi-Fi is a mass market solution, delivering best effort service using unlicensed
frequency bands
Originally, Wi-Fi was intended to support LAN connectivity over a short range in an
indoor environment for private use
It was intended to deliver traffic on a best effort basis without QoS (Quality of Service)
or SLA (Service level Agreement) between an Access Point and the clients
Wi-Fi is by its nature a point-to-multipoint (PtMP) technology

Wi-Fi in a Nutshell
The huge indoor Wi-Fi market that has emerged over the last few years has made the
technology attractive for outdoor applications due to its apparent economy of scale
An examination of the Wi-Fi outdoor user base, indicates that it is commonly
deployed by small limited budget ISPs:» Serving residential users without QOS or SLA
» Over short ranges of several kilometers
» Offering Internet access with low capacity under 1Mbps
The ready availability of chips and reference design in the industry, has reduced the
entry barrier for potential manufactures tempting many vendors worldwide to offer
this technology as a low-end broadband access solution

Wi-Fi Performance Overview
Interference in the unlicensed band used by the Wi-Fi (2.4GHz) is increasing steadily
with the proliferation of Wi-Fi devices
In addition, its incidence is quite random. Part of this interference is due to the
concentration of many Wi-Fi transceivers in a given area and part of it is due to other
systems using the same bands
6RADWIN Training Center |
Wi-Fi Performance Overview
It dramatically affects both the Wi-Fi service availability and capacity:
1. Wi-Fi link operation is not guaranteed due to interference
» The operating frequency channel (20MHz) in many of the Wi-Fi transceivers is manually selected during
network configuration
» Intensified interference while operating the equipment may intermittently drop the Wi-Fi link until the
interference drops to an acceptable level or until channel reselection takes place which may require
manual intervention
» Those Wi-Fi transceivers that dynamically select the frequency channel search for signals with a Wi-Fi
pattern only: During channel selection, they check for the presence of a WiFi signal rather than measure
the spectral energy in the channel
» That means that they are blind to any type of interference not due to Wi-Fi. Thus, these transceivers may
select a channel that is not subject to Wi-Fi interference, but does suffer from interference due to other
radio systems with a spectrum pattern different from Wi-Fi
7RADWIN Training Center |
Wi-Fi Performance Overview
It dramatically affects both the Wi-Fi service availability and capacity:
2. Wi-Fi link capacity is highly vulnerable to Interference
» Wi-Fi clients and AP sense the air-interface before sending data
» Having certain level of interference in the channel might delay the transmission for short or long periods,
» hence, reducing the effective capacity with no way to avoid it
» In addition, when error data is received, the Wi-Fi sender resends the whole packet from the beginning
» In harsh environment this approach not just reduces the capacity but also increase the latency and makes
it erratic, therefore damage the QoS of time constrain traffic as VoIP and video
8RADWIN Training Center |
Long term experience shows that on average, the Wi-Fi network capacity for TCP trafficis less than 30% of the maximum modem rate
Wi-Fi Deployment Limitations
Wi-Fi capacity performance can easily be degraded in certain deployment or service
scenarios, unless special care is taken – and even that may not help
Such degradation increases the TCO (Total cost of ownership)
Typically, the initial equipment cost is a small part of the TCO
But - note that compromising on transceiver equipment quality will also lower the
Link capacity
9RADWIN Training Center |
Wi-Fi Deployment Limitations
Capacity degradation due to a concentration of APs (Access Points)
» The Wi-Fi transmission and reception periods are not constant and subject to the size of the transmitted
packets
» Hence, when several APs are collocated on a site their transmission and reception are not synchronized
» Consequently, they interfere with each other even though they may transmit on different frequency
channels
» The end result is significant reduction of link capacity over a given distance or alternatively, reduction of
link distance for a given capacity
» Spatial separation of the APs improves the performance but requires additional costly space
10RADWIN Training Center |
Wi-Fi Deployment Limitations
Wi-Fi cannot support delay sensitive services
» Being designed for best effort data transmission, Wi-Fi is not “aware” of delay sensitive applications such
as video and voice
» It therefore treats them as regular over-the-air data traffic increasing the end to end delay
» To make matters even worse, this increases the delay variation of delay sensitive traffic
» There are some Wi-Fi clients that support the WMM (Wi-Fi priority policy for Multi Media), being able to
prioritize multimedia packets over other packets during transmission
» Such prioritization is essential but not enough: The Wi-Fi air interface (meaning the algorithm for
modulation selection) is intentionally tuned to deliver packets with PER (Packet Error Ratio) up to 10%,
relaying on higher layers such as TCP to re-transmit the packets with errors. Consequently, the
multimedia packets, carried over UDP are not retransmitted upon error, degrading the end to end
performance of voice and video services
11RADWIN Training Center |
Wi-Fi Deployment Limitations
VoIP traffic dramatically reduce Wi-Fi capacity
» Due to the Wi-Fi air protocol (Air link sensing before transmission and acknowledgment mechanism), a
short packet of 64- 128 bytes as used by VoIP, reduce the Wi-Fi capacity by tens of percent
» Typically, one AP can handle only 7-10 VoIP channels! Obviously, this capacity shortage can be
compensated for by adding more APs, leading in turn to capacity degradation due to concentration as
described in the first bullet above

Wi-Fi Deployment Limitations
13RADWIN Training Center |
To Summarize:
1.Wi-Fi is aimed at indoor LAN connectivity for best-effort data applications2.Wi-Fi technology suffers from inherent drawbacks that prevent it from being appropriate to high-end broadband applications like long range backhaul, mission-critical or business applications3.The vulnerability of Wi-Fi links to interference results in erratic capacity in an outdoor scenario
All of these weaknesses limit the Wi-Fi solution investment protection, adding up to a relativelyhigh Total Cost of Ownership along with degraded price/performance at the high end
Performance Overview
14RADWIN Training Center |
Automatic Channel Selection (ACS)
» Both during configuration and as a result of the link dropping, RADWIN radios automatically chooses the
clearest operating channel. In the event of a link drop it re-synchs itself within few seconds. This
minimizes service interruption due to interference and ensures high link availability
Synchronous TDD
» The WinLink 1000 transmits and receives on fixed timing basis, regardless the level of interference.
Therefore, unlike Wi-Fi, its transmission cannot be blocked by high level of external interference
Automatic Repeat reQuest (ARQ)
» The WinLink 1000 transceiver checks every portion of the packet immediately when it received and upon
error it requests re-sending again and again it until it correctly received. This process avoids loss of
capacity due to retransmission of the whole packet. It also improves the link error performance to PER
better than 0.1% for time sensitive UDP traffic as TDM, VoIP and video while keeping the latency to the
minimum necessary
15RADWIN Training Center |
Support of Data and TDM
» WinLink 1000 is built to support both data over Ethernet and native TDM. As mentioned above, special
care of TDM traffic enables low error rate with low end to end delay. · Stable and fixed capacity for
variety of services The WinLink 1000’s air interface ensures that the net capacity is indifferent to packet
size. It is therefore highly efficient even for services with short packets as VoIP
Support of collocated PtP links
» The WinLink 1000 supports Hub Site Synchronization (HSS). HSS is a unique Radwin collocation
technology designed to support Multiple Point-to-Point architecture from one hub site to many remote
sites. It avoids mutual interference between the collocated PtP transceivers, therefore maximizing the
dedicated capacity per site
Performance Overview
Conclusions
16RADWIN Training Center |
1. Wi-Fi offers low cost outdoor wireless solution to the low-end market with best-
effort SLA
2. As shown, Wi-Fi link’s availability and capacity are highly vulnerable to outdoor
interference
3. Further, its capacity is subject to the type of traffic and to the network topology,
therefore it does not fit broadband mission critical applications as backhaul or
business environment
4. This raises serious questions about the true economics of Wi-Fi: Low initial costs,
heavy operational costs due to “patching” an inferior solution along with a loss of
customer confidence – and the customers, themselves!
Conclusions

5. RADWIN radios are designed to ensure high availability of its broadband link under
harsh and noisy conditions – they maintain stable and predictable capacity with short
latency, regardless the traffic characteristics or the network topology

Air Protocol Highlights
HBS Activation
The HBS will not transmit unless it has been activated (Inactive State)
Upon reset or activation, the HBS scans all channels (selected in ACS) for the less
interfered channel (lowest noise)
The less interfered channel is assigned for the entire sector
When activated, the HBS will commence transmitting and receiving packets related to
sector management only
51RADWIN Training Center
a) HBS IP address
b) HBS Sector name
c) HBS Frequency (or ACS)
d) Sector ID
HBS Activation requires:
HSU Registration
Assuming that the Sector HSUs are mounted aligned and powered up, the HSUs
will discover the HBS establishing links for management only.
At this point the HSUs may be managed over the air.
As soon as the HSUs are configured to your satisfaction, you must register them
on the HBS.
52RADWIN Training Center
HSU Registration
Registration of an HSU enables service traffic between the HSU and the HBS.
During the registration process, you assign time slots to each HSU.
A total of 16 time slots are available to each HBS to be distributed among the HSUs in
the sector.
The relative number of time slots determines the relative amount of service each HSU
will receive.
53RADWIN Training Center
HSU Registration
Each HSU receives at least one time slot.
To disable an HSU you must deregister it.
A suspend mechanism is also available, to suspend service on an HSU for a limited
period.
For each registered HSU, you can set separately, the uplink and downlink Maximum
Information Rate (MIR) in Mbps or leave it at Best Effort.
You may also manage an HSU Connection table to enable and disable connectivity
between HSUs in a sector.
54RADWIN Training Center
“Synchronize HSU” – HSU is synchronized to HBS. HSU might have default Sector ID or the same Sector ID like the HBS No service to HSU yet
“Register HSU” – HBS commands to the synchronized HSU the required Sector ID and services HSU is associated and registered to the HBS HSU receives the same Sector ID HSU is assigned with a service (Time Slots)
“De-Register HSU” – HBS commands to release the HSU from the HBS The HSU deletes its Sector ID The HSU starts re-scanning of HBS
“Suspend HSU” – The HSU will not communicate the original HBS for a duration of configurable X seconds The HSU is re-scanning for other HBS with the same Sector ID

Sector site planning consists of a set of surveys, which must be carried out before any equipment is deployed.
If for some reason, the outcome of any of these surveys is negative, HBS or HSU re-location will need to be considered
Recommended Equipment
For Preliminary Survey:
• Topological map of the area• Urban map of the area• Compass • Link Budget Calculator and/or Radio Planner
For Physical Survey:
• 100 meter tape measure• Ohmmeter, to check ground connection• Binoculars• Map• Digital camera• Paper, pencil, and a clipboard• GPS device (optional)• Compass (optional)
89RADWIN Training Center
Recommended Equipment
For RF Survey:
• Spectrum Analyzer with Max Hold function capable of capturing screens and data • RF accessories (connectors and cables)• Communication devices (for example, cellular phones, or a set of walkie-talkies)
For physical installation:
• Crimping tool for RJ-45 (if the ODU-PoE cable is without connectors)• Spanner/wrench 13 mm (½”)• Drill (for wall mounting only)• Cable ties• Sealing material• ODU grounding cable 12AWG
90RADWIN Training Center
Preliminary SurveyPerform before visiting potential installation sites:
1.Mark the designated installation sites on a topographic map of the area
2.Measure the distance between the sites; check that it is within the specified
range of the equipment
3.Check the area between the two sites for obstructions such as:
• High ground - hills or mountains
• Lakes or large bodies of water
• Construction cranes
91RADWIN Training Center
Outdoor CAT-5e; Maximum cable length: •100m for 10/100BaseT•75m for 1000BaseT (GbE PoE)
Preliminary Survey (continued)
4. Determine and record the compass bearings between HBS and HSU ODUs,
relative to north.
5. If there are obstructions between the two sites, calculate the Fresnel Zone
6. If the sites chosen do not meet requirements, consider alternative sites.
7. Use the Link Budget Calculator (on the CD supplied with the equipment or using
the RADWIN Manager) to determine the expected performance.
92RADWIN Training Center
Physical SurveyEnsure that the sector sites are suitable for the wireless network:
1.From the compass readings taken in the preliminary survey, find the azimuth (horizontal position) that each HSU ODU should face towards the HBS ODU.
2.Using binoculars, locate any obstructions such as tall trees, high buildings, hills or mountains. Look for other RF towers between the two sites. Mark the locations of the obstructions on the map.
3.Determine the location for the ODU (having regard for existing rooftop installations and tower space). It should be above any obstructions, considering the Fresnel zone.
4.When installing ODU on a tower, make sure that the tower is far enough from overhead electric power lines.
5.Determine a location for the indoor equipment; it should be as close as possible to the ODU. At an existing site, there is probably an equipment room with cable-routing channels.
93RADWIN Training Center
Physical Survey (continued)
6. Measure and record the path length of the cable from each ODU position to the indoor equipment room.
7. Determine the ground and lightning connection points of the installation. The ODU and PoE must both be grounded.
8. Using the Ohmmeter, measure and record the resistance of the required installation to the grounding point. The resistance must be less than 1O ohm.
9. Review the results of the physical site survey. Decide if the site is suitable for the wireless network installation:
• If the site is suitable, you may proceed (RF Survey)• If the site is not suitable, survey another site
94RADWIN Training Center
ODU operating temperatures: -35°C to 60°C (-31°F to 140°F)IDU operating temperatures: 0°C to 50°C (32°F to 122°F)
RF Survey
• The RF survey examines the wireless environment of the installation site, to
determine whether there are available channels within the radio operating
frequency band.
• An RF survey is performed using a spectrum analyzer.
• It is advisable to familiarize yourself with the spectrum analyzer before going out
on site, specifically the Max Hold and Marker functions.
• You should perform the RF survey at each of the proposed sector sites.
• The survey should be carried out during a busy time of day, to best judge the
worst-case radio interference. Allow 2-4 hours duration for a good RF survey.
95RADWIN Training Center
RF Survey (continued)
Interference may arise from -
• Self-interference from collocated RADWIN radios
• Other collocated radio devices installed on the same site.

RF Survey (continued)
To avoid or minimize interference, follow these recommendations:
• For collocated RADWIN units, use an HSS unit to synchronize between them.
• Select a different operating channels for each collocated RADWIN unit.
• If one or more collocated units are not RADWIN units, ensure that there is a physical
separation of at least three meters between a RADWIN unit and any other collocated
radio on the site.
• Use the largest possible frequency gap between these units
• Choose the best frequency channel (as clear as possible from interference). You may
be able to change the band used for the sector - depending on HBS model and
regulations.
• Decreasing the Tx Power of a sector will reduce collocation interference

Installing the Hub Synchronization Unit
103
RADWIN Training Center
• When several HBS sector radios/PtP radios are collocated at a common hub site, interference may occur from one unit to another.
• The RADWIN Hub Site Synchronization (HSS) method uses a cable connected from the master ODU to all collocated ODUs; this cable carries pulses sent to each ODU, which synchronize their transmission with each other.
• The pulse synchronization ensures that transmission occurs at the same time for all collocated units.
• This also results in all of the hub site units receiving data at the same time, eliminating the possibility of interference that could result if some units transmit while other units at the same location receive.
For a single HSS unit, ensure that the collocated units are connected in sequence from SYNC 1.
If an ODU is removed from the hub site, then all remaining ODUs must be reconnected to maintain the connectivity.
You may cascade (daisy-chain) two or more HSS Units with an HSS cable.
Installing the HSSU
104
RADWIN Training Center
• A single HSS unit supports up to ten collocated ODUs (PtMP and/or PtP, co-exist).
• In addition to each unit being connected to its PoE device, the collocated unit has an additional cable that is connected to the HSS Unit.
• The HSS Unit is a compact, weatherproof (IP67) connector box that is installed on the same mast as the ODUs.
• All collocated units connect to this box using CAT-5e cable.
• The HSS unit is supplied with ten protective covers; any port not in use must be closed with a protective cover.
Installing the HSSU
105
RADWIN Training Center
1. Unscrew the protective cover from the port marked SYNC 1.
2. Connect the RJ-45 connector from one end of the prepared CAT-5e cable to SYNC 1.
3. Connect the other end of the CAT-5e cable to the ODU connector labeled SYNC.
4. Tighten the protective seal that is on the prepared cable over the RJ-45 connector.
5. Repeat for all ODUs that are
to be collocated at the hub site.
6. The next ODU to be
connected is inserted in SYNC 1,
SYNC 2, followed by SYNC 3 and
so on.
Cascading HSSUs
106
RADWIN Training Center

RADWIN Training Center
1. Up to nine ODUs may be connected to the first HSSU (left) using HSS ports SYNC 1, SYNC 2, SYNC 3,... up to SYNC 9 in consecutive order without leaving empty ports.
2. The next available SYNC port of the first HSSUN (left) should be connected to SYNC 10 of the second HSSU (right)
3. In the example below, the next available port on the first HSS unit is SYNC 6.
4. The 2nd HSSU may be filled out with up to nine more ODUs in reverse order.
Total HSS Cable Length
108
RADWIN Training Center
The total path of the HSS sync pulse must not exceed 300m. This applies no matter how many HSS units are used.
For example, for a HSSU with 5 ODUs, one should calculate the total length as the path the pulse signal travels till it reaches its final SYNC port (last ODU):
Total length = L1 + L2 + L3 + L4 + L5 + L6 + L7 + L8, where L2=L3, L4=L5 and L6=L7

Installing the GSU
110
RADWIN Training Center
• The GPS-based synchronization unit (GSU) is designed to handle inter-site interferences under large-scale deployment scenarios.
• The GSU is an outdoor unit consisting of a standard Wireless Link enclosure, a GPS antenna and a PoE device.
• The GSU is connected to a 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.
• The GSU receives a synchronization signal from the GPS once per second.
• It distributes a RADWIN proprietary synchronization signal to all other ODU units using the RS422 protocol and the standard HSS mechanism, where the GSU acts as an HSM unit.
• If the GSU does not 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 GPS signal recovers.

• Each ODU should be pre-loaded with an IP address.
• This may be done prior to deployment in the field, or on-site using a Laptop
computer.
• The ODU can be mounted on a pole or a wall. In both installations, the supplied
mounting kit is used to secure the ODU.
1. Ensure that the ODU is properly grounded2. Mount the ODU onto the pole or wall. Ensure that the unit is oriented so that the

Aligning HSUs to HBS
114
RADWIN Training Center
HSU antenna alignment to an HBS can be performed using HSU ODU’s audible tone.
1. Ensure that the sector antenna of the HBS is aligned precisely to the sector it is
intended to cover. Use a compass and topographical maps to do this.
2. For both the HBS and HSUs: Using a coax cable with N-Type connectors, connect
the vertical polarization connector of the antenna to the ANT 1 connector of the
ODU.
3. Then, using a second coax cable with N-Type connectors, connect the horizontal
polarization connector of the antenna to the ANT 2 connector of the ODU.
4. Ensure that power is connected to the site PoEs across the sector.
Aligning HSUs to HBS (continued)
115RADWIN Training Center
5. Provided that an HSU detects the signal from the HBS, the ODU starts beeping 20
seconds after power up, and continues beeping until the HSU is aligned to the HBS,
and the alignment is complete.
6. Make a horizontal sweep of 180 degrees with the HSU antenna so that the
strongest signal from the HBS can be detected.
7. Slowly turn the HSU antenna back towards the position of the HBS, listening to the
tone until the best signal is reached. See the following figure for audible signal
variations.
Aligning HSUs to HBS (continued)
• Three beeps and a pause is 'best signal so far'
• Two beeps and a pause is 'signal quality increased'
• One beep and pause is 'no change in signal'
• Long beep and short pause is 'signal quality decreased'
• One beep and a long pause is 'no air link'
• Any other signal does not relate to antenna alignment

1. HBS alarms2. Alarms of all HSUs within the sector
Using the Spectrum Viewer
193RADWIN Training Center
Two ways to run it:
From the HBS – •Users have a choice of analyzing all sites in the sector in one run, or making a selection.•Users may expect a “noise hump” around the channels used by the sector, due to the duty signals from the HBS.
From the HSU – •Spectrum View may also be run on a managing computer directly connected to an HSU.•Remember that in such a case the results will be quite different if the HSU is part of a sector (registered or not) or if it is completely stand-alone, for example using a different spectral range and operating Band from the HBS.
Using the Spectrum Viewer
194RADWIN Training Center
Where is the Spectrum View Data stored
• Spectrum View data is always stored in the ODU originating the analysis.
• The HBS maintains the last Spectrum View analysis data for all members of the
sector.
• If you run Spectrum View from a directly connected HSU, it stores its own data,
which may be quite different from the analysis obtained for the same HSU from the
HBS.

• There is no difference in principle between running a Spectrum View analysis for an HSU and running it for the HBS.
• There is a major difference between running Spectrum View on an active HSU (registered or not) or in total isolation from the sector.

1.All VLAN actions and manipulations that are related to DATA, are configured and performed by the HSU(s)
2.The HBS does not audit the ingress VLAN TAG coming from the HSUs within its sector
3.To control the traffic within the sector we can use the Connectivity Matrix (HBS Configuration)
