APU(Access Point Unit)
The following is a list of WLAN Cable Access Point 6220 APU features:
Enclosure has three sorts of connector which support the connection to
CATV Cable Network, Antenna and Monitoring Equipment.
Coaxial Port has the standard type of connector so that can be efficiently
adapted to every connector regardless of the termination type of coaxial
cable like “Trunk or Drop Cable”
Operation Power and Data Traffic are mixed at a signal amplifier as
TBA(Trunk Bridge Amplifier), PI(Power Inserter) and supplied to the
coaxial port on the APU through coaxial cable.
Monitoring Port can provide the safe testing method for measuring
CATV signal to an installation engineer by attenuating RF power and
protect AC power signal.
Basically, Two kinds of mounting types are available for APU, such as a
steel wire strand mounting and wall mounting, but in case of wall
mounting, another optional bracket kit will be needed for installation.
The available antennas are totally three types such as ‘Directional
Type’, ’Bi-directional Type’ and ‘Omni-directional Type’ , which can be
mounted on the front or rear cover of APU with a Universal Bracket.
Cable Modem Module is compliant to DOCSIS 2.0(Cablelabs) as well as
DOCSIS 1.1 and WLAN AP support the secure mode connection which
mean that wireless traffic from APU and CSU is not scanned and
detected by a conventional sniffing program like ‘Netstumbler’.

Planning your WLAN Network
The wireless network is much different with a wired network. The
Installation of a wireless network requires some additional planning.
This planning includes RF Link Engineering like RF Path planning, site
selection, and back-bone network preparation.
The radio links between all end sites are specified as three types of
environmental connection listed as below:
LOS(Line Of Sight)
OLOS(Optical LOS)
NLOS(Non LOS)
Because High Frequency Radio travels in a straight forward line, a clear
LOS(line-of-sight) between antennas is efficient and ideal. Frequently,
locations of the desired links are fixed.
When you cannot achieve a clear line-of-sight, you must plan according
to a basic consideration:
The Basic considerations for sites include:
▪ Installation Facility must be constructed (Electric Pole, Tower)
▪ Possibility of future obstructions
- Trees that may obstruct the path
- Buildings between the sites that may obstruct the path
▪ Lightening
▪ Distance between the sites and Network Structure.
▪ Strong RF interference
26
Site Survey & Planning
Definition
A site survey is a task-by-task process by which the surveyor discovers
the RF behavior, coverage, interference, and determines proper hardware
placement in a facility. The site survey’s primary objective is to ensure
that mobile workers and the wireless LAN’s clients experience
continuously strong RF signal as they move around the facility.

Wireless Network Planning
Procedure 1 (Location)
1. Select and identify enough location candidates to determine freely as
the install point regardless of some design change to some extent.
2. The most crucial parameter is the range at which APU and CSU or
other Wi-Fi Client are required to operate. The range can be
determined by a conventional formula which consider a various kinds
of environmental and radio equipments.
3. Another consideration in installing APU and CSU is the network
connection like a CATV Coaxial Cable and CAT5 Ethernet Cable.
Even though some location is the best location in terms of RF
performance, the actual installed location is restricted by a limitation
of cable reach.
Procedure 2 (Radio Link Path)
1. Choose the proper antenna type with a site survey result.
2. For best performance, mount the APU and CSU in a location where
there is LOS(Line Of Sight) to each antenna.
3. Perform the field survey to summarize every obstacle like tree and
earth bulge in consideration of OLOS(Optical LOS).
4. With the site survey result, adjust the tilt and angle of antenna so that
there is maximum clearance within the FRESNEL ZONE of the
direct path.
Note: The best means of achieving FRESNEL ZONE clearance is to
raise the height of APU or CSU mounting point as high as possible
5. In order to get the more exact information on RF radio link path,
Calculate the Link Budget for Radio Link between APU and CSU
which is referred in the end of this section.
Note: The link budget is a rough calculation of all known elements of the
link to determine whether the signal will have the proper strength to the
other end of the link.
Procedure 3 (RF Channel Selection)
1. Check all range of channels by RF measurement with Frequency
Analyzer in order to see the interference effect with APU and CSU.
Actually, RF interference is likely to arise from any other wireless
system operating within the same frequency band as ISM/UNII Band
Radio Products.
Note: The final selection of operating channel should be done with
the testing results of both APU and CSU.
Procedure 4 (Radio Performance Tuning)
Please refer to the Radio Link Test

Procedure 1-5
Checking CATV Signal and Power Level and Tuning
Action
Step
Action
1. Connect an actual coaxial cable to the coaxial port on the APU.
2. Connect a measurement coaxial cable to the monitoring port on APU.
3. Measure the Signal Power level at monitoring port
Note: In case of installation using a Trunk or Distribution Cable &
Connector, it is crucially recommended to measure the RF Signal level
directly at the termination of the coaxial cable from CATV AMP(TBA)
or Splitter before connecting to APU in order to ensure a perfect
operation of Cable Modem inside APU.
If the measured Signal level is outside from the allowed range referred in
DOCSIS, you should adjust the AMP Power level or perform another
proper tuning method to meet the requirement of RF signal level.
It is also recommended to measure AC voltage from CATV UPS Power
Supply to ensure a perfect operation.
Note: In case of installation using a Drop Cable, it is recommended to
measure the AC voltage from Local CATV Power Supply to ensure a
perfect operation. But if you can confirm that a power supply facility is
compliant to the power requirement of APU, this step can be skipped
4. Check if the acquired power level converted by adding 20dBmV to
monitored value satisfy the range (-15dBmV ~ +15dBmV) referred
in DOCSIS standard. But, some level margin should be added to the
measured power level by 1 ~ 3 dB.

Note: If there is no LED light, check if the power supply which provides
the CATV (HFC) network with AC power (45 ~ 95VAC) signal is
working properly and that the CATV power is detected at the end of the
coaxial cable. (If any problem has been found in the power system, the
unit has to be entered into a Repair Process)
6. Check if LED 2(CM Link) flashes for over 100 seconds from when
power is first supplied.
If the LED flashes for more than 100 seconds, check if the data signal
level at the monitoring port on the APU meets the recommended
range of the signal level.

Step
Action
1. Loosen the EMI cap and slide the CAT5 or 6 cable without RJ45
connector into the hole of the EMI cap shaped like hood.
2. Follow the conventional procedure of creating a CAT5 or 6 Ethernet
cable
Note: It is recommended to use a shielded cable like S-FTP(Foiled
Twisted Pair) or STP (Shielded Twisted Pair) in which wire pairs are
covered with overall shield material to prevent EMI effects to or from
the near electronic devices or facilities.
Note: The cable from CSU to POE Injector and from POE Injector to
CPE (PC) should be a straight-through cable.
3. Connect a cable to the CSU’s POE port through the hole of EMI cap
and tighten it firmly

Mounting Tips
•
Verify the Line-of-Sight -- Before installing the CSU, make sure a clear lineof-sight exists. Line of sight (LOS) can be defined as each antenna clearly
seeing the other antenna, and seeing the remote locations when viewing from
the central base location. Be sure to look level with the center of origin of the
transmission (i.e., the middle of the antenna). Repeat this procedure from the
remote location. Any disruption of the signal path due to trees, buildings, or
any other obstructions may cause the link to function incorrectly. If you see
any obstructions between two antennas, move one or both antennas to
another location.
•
Use mounting hardware provided to secure the unit to the pole.
•
Leave the unit mounting loose enough to allow for movement when
performing the alignment/testing procedure. The unit should be tightened
only after the alignment/testing procedure is completed.
•
Install the unit away from microwave ovens and 2.4 GHz cordless phones.
Microwave ovens and some cordless phones operate on the same frequency
as the unit and can cause signal interference.
•
Begin at the lowest point, so the tape overlaps from bottom to top creating a
shingled effect. This creates an effective barrier against water runoff. Apply
this "shingle effect" to each layer of the sealing process. Apply two layers of
electrical tape to the connector, and leave approximately 3 inches of cable
exposed on either side of the connector.
