The AN-50 is a high-performance, high-speed wireless Ethernet bridge that provides a
scalable platform for the deployment of multi-services over a common equipment
infrastructure and management system. The AN-50 System can operate in a Point-To-
Point (PTP) or Point-To-Multipoint (PMP) mode depending on the software configuration.
In PTP mode, only two stations can communicate with each other, while the PMP mode
consists of one or more Subscriber Station(s) that communicate with the Base Station.
For complete procedures on software upgrade and use of the option key please refer to
sections 8.1 and 8.6.
The AN-50 system operates in the unlicensed band of 5.8 GHz and includes advanced
technologies to address any potential inter-cell interference issues. The system also
features adaptive modulation in both directions in PTP mode for automatic selection of
modulation schemes, including BPSK, QPSK, 16 and 64 QAM to maximize data rate,
and hence spectral efficiency. Additionally, the system delivers enhanced security
through a proprietary, over the air encryption scheme that significantly improves the
privacy and integrity of all traffic.

The AN-50 system utilizes Redline’s advanced Medium Access Control (MAC) design to
provide efficient transmission of data in both PTP and PMP modes. In PMP mode, the
MAC incorporates a proprietary polling algorithm to support up to 256 individual
subscriber stations from a single base station operating in a single sector. Note that
multiple base stations can be installed on a single roof-top or tower to provide multi-
sector coverage.
A single sector AN-50 PMP implements a distributed wireless L2 switch, with one uplink
port located on the sector controller (master) distributing bandwidth to a variable number
of subscriber stations (slaves).
• Each subscriber station (or slave) is considered a separate wireless link.
• Each configured wireless link adds to the switch one slave port that is the
Ethernet port on the corresponding subscriber station. This is achieved
during provisioning.
• Each link (slave port) is assigned one ID that is used to manage both the
connection traffic and the wireless link.
• The switch supports one broadcast/multicast group called default group.
• The default group is assigned automatically to a fixed ID.
The AN-50 MAC utilizes a request/grant polling mechanism to determine which
subscriber station requires bandwidth. This is achieved by periodically polling each
subscriber station to determine if there is a request for bandwidth. If the SS requests
bandwidth then the MAC allocates the appropriate number of time slots, in both the
downstream and upstream direction, in accordance with the CIR rate limits specified for
that particular SS. The AN-50 PMP system supports 18 programmable CIR levels.
Through an external calculator the minimum Committed Information rate CIR rates
allowed for each SS can be determined. Note that a minimum CIR of 8kb/s implies
almost no CIR, and is referred to as Best Effort (BE) services.
With multiple subscriber stations vying for bandwidth, the MAC ensures that time slots
are allocated in a balanced manner, according to the different CIR levels, during periods
of over-subscription. For example, during peak times, the MAC will first deny time slot
allocations for everything above the provisioned CIR, and then reduce bandwidth in a
proportional manner to the remaining units with varying CIR levels and priorities. With
the support of CIR, the service provider can offer different grades of service to each end
user in a controlled manner based on their service level agreements or contracts

This section of the manual presents a basic overview of the steps required to install the
AN-50 terminal, outdoor transceiver, antenna and associated equipment.
Figure 7 below illustrates the primary system components and cables. The power cord
connects to a 110/220/240 VAC standard power outlet, while the CAT 5/UTP cable (not
included) connects the terminal to the data network via a standard 10/100BaseT
Ethernet connection. The provided IF cable connects the terminal (located indoors) to
the T-58 Transceiver (located outdoors), and carries the transmitted and received signal,
DC power for the AN-50 radio, as well as control and reference signals. Note that the
provided IF cable is meant for exterior use, and should be used for only minimal interior
runs to connect to the terminal. Also note that the BNC connectors are for future use.
Figure 7: AN-50 System Installation
The terminal is for indoor installation only, while the transceiver and antenna (together
known as the AN-50 Radio) are mounted externally. The principal steps in installation
are:
1. Conduct a general site survey
2. Install the transceiver and antenna
3. Install the IF cable
4. Install the AN-50 terminal
5. Align the antenna
Each step is addressed in more detail below.
Page 19 of 76

AN-50 System User Manual
Redline Communications …..solving the first mile challenge.
7.1. General Site Survey
The first step in installing the AN-50 system is to conduct a general site survey.
Although the installation steps are relatively straightforward, they do involve some
construction and electrical work, which is best performed by a professional installer.
The following site survey steps should be followed:
Determine the optimum location. The first key step in the deployment exercise is to
determine and identify building candidates that can be used to support the link. A critical
parameter to consider is the range at which the subscriber station, base station or
terminals are required to operate. Range performance is determined by empirical
formulas that consider a number of equipment and environmental factors described in
Section 9.7 of this manual. Ensure that the installation sites meet these range
performance requirements before moving to the next step. You may use Redline’s Link
Budget Tool to determine the expected performance of the link. The Link Budget Tool
can be obtained by contacting your Redline certified partner or system integrator. See
Section 9.7.1 on page 59 for more information.
Verify the accuracy of any building drawings/blueprints that may be available. The
installation process may require penetrating the building to run the IF cable between the
outdoor and indoor units. In this regard, it is imperative that the blueprints and/or
drawings of the building are up to date and accurate. It may also be possible for the IF
cable to be installed on the outside of the building leading to the antenna location on the
roof of the building.
Identify the best path for the link. For maximum performance, it is recommended to
mount the antenna in a location where there is line of sight to the remote terminal. If
possible, the antenna should be positioned such that there is maximum clearance within
the first Fresnel zone of the direct path. Refer to Section 9.3 for a full description of
Fresnel zone clearance and its impact on signal propagation. The best means of
achieving Fresnel zone clearance is to mount the antennas as high as possible, on
either a tall building or tower, as shown in Figure 8 (Vertical mount system is shown).
The AN-50 system is also designed to operate in non-line-of-sight (NLOS) conditions, as
a result of the OFDM technology incorporated in the platform. Under NLOS conditions,
the best method of obtaining a proper RF link is to evaluate different antenna
orientations and choosing the one that results in the best Signal to Noise (SINADR) ratio
and highest Received Signal Strength (RSSI) value. Often, this can be achieved by
introducing an RF multipath condition by orienting the antennas towards a structure in
sight of both the local and remote antennas. If the obstruction in the path is not
exceptionally high, it may be possible to aim both antennas near the top of the
obstruction. With the use of OFDM in the Redline system, any additional multipath
signals introduced will provide additional opportunities for an improved link. For PTP and
Subscriber Station it is very important that the above steps are carefully followed . For
the Base Station the accuracy of the aiming is not so important as the antenna is using a
wide angle.
