1. Overview
1.1. Introduction
This document describes the features of the wireless tap NWTAP-100 as well as how
it can be installed to provide the most effective service to end users.
The NWTAP-100 is an outdoor hardened wireless lan access point solution which
uses an internal cable modem as the backbone interface and AC line power from the
feeder cable for power. The wireless LAN tap-off is an all-in-one unit which consists
of a cable modem, WiFi access point, power supply unit, antenna and tap-off in an
outdoor-hardened housing.
It provides a low cost and easy to install WiFi access hotspot to homes and
businesses by simply removing the old tap and installing the wireless tap.
Standards based
The internal cable modem is DOCSIS 2.0 compliant based on the Broadcom
BCM3349. It is fully interoperable with all CMTS models available in the market
today.
The internal WiFi is based on the 802.11g standard which is backwards compatible
to the 802.11b. The wireless chipset is based on the Broadcom BCM4318.
Security
Security is of utmost importance in todays wireless networks which are exposed to
hackers and other mallicit users. The NWTAP-100 fully supports all the latest 802.11
security enhancements including WPA2.
Future proofed
The NWTAP-100 supports remote software upgrade via TFTP. The modem will
maintain the current version of software while downloading the new version in order
to provide crash proofing. Netwave will continue to include enhancements and
customizations to the existing software so that customers can continue to use the
wireless tap most effectively for many years.
Flexible service platform
The software running the wireless tap is a full featured gateway which can be used to
support commercial high speed access to homes and offices or provide public
hotspot service.
The flexible antenna mounts can be used to support a tap housing mounted antenna.
Since the antenna output is based on an SMA connector, various off-the-shelf
antennas may also be used.
The unit can be strand mounted or can be mounted at the side of buildings and
provides WiFi access as well as wired CATV signals.

As shown in fig. 2, the trunk line RF is sampled to the tap-off splitter circuit as in a
conventional tap-off but part of this signal is also coupled to an internal cable modem.
The cable modem then transfers the Ethernet packets to the wireless part for
communication via 802.11b/g radio.
The AC power existing in the trunk network is also sampled by the power part so that
the DC powering for the cable modem and the wireless lan can be provided.

The above figure shows the RF signal level attenuation as they pass through the
wireless tap with 8 subscriber ports.
The RF signal level output at the subscriber ports are attenuated by approximately,
-Y-1-0.5-1-0.5-12 dB
The actual tap value in dB displayed at the bottom of the tap excludes the 1dB
attenuation for the 16Mhz HPF and -1dB attenuation for the cable modem.
-Y-0.5-0.5-12 dB
The RF signal level output at the cable modem is attenuated by approximately,
-Y-1-0.5-17 dB
This level should be considered so that the appropriate RF level is input into the
cable modem. The cable modem input level should be within the range 15~+15dBmV.
The main splitter is implemented in the form of a plug-in type coupler which allows
this value to be easily changed in the field as shown in section 5.2.2.

Netwave Proprietary and Confidential
Verify that the wireless signal strength(the received power level) shown
by the client utility when the client is below or close to the wireless tap is
>-55dBm
Check the notebook IP using the “ipconfig” command in the command
prompt and verify that it has acquired the correct IP from the CMTS
DHCP server or has acquired the IP 192.168.x.x from the DHCP server
in the wireless tap. The wireless tap has an internal DHCP server which
takes over when an external DHCP server is not available.
Access the web management page of the wireless tap via the address
“http://192.168.100.1:64680
”. The special port number 64680 is used in
order to secure the web access as much as possible.
If web access is still not possible, please set the static IP of the notebook
to 192.168.100.10
and the subnet mask to 255.255.255.0
Login using the id/password = admin/cableroot
As described in section “4.1 Webui Based Configuration”, the proper
operation of the cable modem is verified

2.7. Performance Measurement
At the client location, the signal strength shown by the client utility should
typically be >-75dBm. At such a power level, wireless tap can produce
the maximum throughput which would be a limitation of the cable
modem.
Once the client has established RF link to the wireless tap and has
acquired the proper IP address to be able to access the Internet, the
performance test for actual TCP data throughput can be performed
The throughput can be checked by using any of the three following
methods. In order to make the throughput shown as reliable as possible,
the server accessed should preferably belong to the MSO or ISP that
has the wireless tap connected to it’s CMTS.
1) A speed checking web site can be used to check the throughput
2) FTP can be performed
3) Web download can be performed
Any of the three methods will show the TCP data throughput which
should will be limited mostly by the throughput of the cable modem. Even
the raw data throughput of the 802.11g wireless is 54Mbps, the actual
TCP throughput can reach roughly half this rate. However, the cable
modem throughput is mostly limited by the MSO to be less than 15Mbps.

3. WLAN Site Survey and Planning
The 802.11b/g standard uses the 2.4Ghz frequency. This high frequency radio
travels in a straight forward line and a clear LOS(Line Of Sight) path between the
wireless tap antenna and the subscriber antenna is the ideal situation.
However in the real world situation, the 2.4Ghz frequency used by the wireless lan
belongs to the ISM/UNII band which is shared with various other applications
including the digital cordless phone. Also, current and future obstructions need to be
considered. Therefore, a strong RF signal is a must.
The most basic steps for the installation include.
1. Identify the target subscriber location
2. Determine the location of the tap to be replaced or location where the
wireless tap will be installed
3. Choose and install the antenna for the best radio link
4. Perform a RF scan around the wireless tap and choose the optimal RF
channel
5. Perform a throughput check so that greater than 10Mbps throughput
performance for TCP or UDP data can be achieved
3.1. Location
Select the location which provides the closest distance and minimal
obstruction to the current or potential future client location. The ideal
case would be LOS.
Since the wireless tap is most easy to install if the legacy outdoor strand
mounted tap is replaced, a legacy tap location with good reach of client
location should be taken as first priority.
If such a tap is not available, a separate strand mounting or mounting at
the side wall of a building or similar tall structure should be considered.
In such a case, the availability of CATV coaxial cable with AC power and
DOCSIS signal should be considered.
3.2. Radio Link Path
After the location is selected and wireless tap installed, the radio link
path should be measured and determined if adequate signal level can be
received at both ends.
Perform a site survey by measuring the radio signal strength at various
locations around the wireless tap where current or future clients maybe
located.
Radio signal level detection procedures are described in more detail in
the “Installation” chapter.
If the radio signal level is determined to be below the required level, the
antenna position and/or direction should be adjusted first. If this is also
not adequate, the antenna type maybe changed to a type with more
directivity. However a more directive antenna implies that the radio
signal tapering outside of the target area needs to be considered for
future clients.
Also, the client side AT(Access Terminal) device can be changed to one
with higher antenna gain for better radio detection.

3.3. RF Channel Selection
As described in the “Installation” chapter, the frequency band occupied
by the wireless LAN can be scanned using a client utility or it can be
scanned using measurement equipment such as spectrum analyzer.
The client utility can detect the presence and signal strength of all
wireless LAN channels that can be detected while a measurement
equipment can also detect the presence of all other signals that share
the ISM/UNII band.
After the RF scanning is completed, the operating channel can be
selected based on the results.
As shown below, if any other wireless LAN channel can be detected, the
selected channel should be spaced at least 4 channels apart to minimize
signal overlap. If this is not possible, the selected channel should be
spaced as far away from other wireless channels as possible. At the
same time, it should be free of RF signals from other equipment that
share the ISM/UNII frequency.
If a particular channel has a signal strength of <-90dBm, this channel can
be considered unoccupied during the channel planning.
