2.3 Working Modes
Three working modes are supported by all Stellar APs:
•Express mode - Plug and Play: Secure Web managed (HTTPS) cluster
deployment
Stellar Series APs by default operates in a cluster architecture to provide
simplified plug-and-play deployment. The access point cluster is an
autonomous system that consists of a group of OmniAccess Stellar APs and a
virtual controller, which is a selected access point, for cluster management.
One AP cluster supports up to 64 APs. The access point cluster architecture
ensures simplified and quick deployment. Once the first AP is configured using
the configuration wizard, the remaining APs in the network will come up
automatically with an updated configuration. This ensures the whole network
is up and functional within a few minutes. Stellar Series APs also supports
secure zero-touch provisioning with Alcatel- Lucent OXO Connect R2, a
mechanism by which all access points in a cluster will obtain bootstrap data
securely from an on premise OXO Connect.
•OVC mode - Cloud enabled with OmniVista Cirrus
Stellar Series APs can be managed by Alcatel-Lucent OmniVista® Cirrus cloud
platform. OmniVista® Cirrus powers a secure, resilient and scalable cloud-
based network management platform. It offers hassle free network
deployment and easy service rollout with advanced analytics for smarter
decision making. Offers IT friendly Unified Access with secure authentication
and policy enforcement for users and devices.
•OVE mode - OmniVista 2500 managed deployment

All rights reserved. Passing on and copying of this document, use and communication of its contents not permitted without written authorization from HAN-Networks.
Stellar Series APs can be managed by Alcatel-Lucent OmniVista® 2500 on
premise Network Management System. The access points are managed as one
or more access point (AP) groups (a logical grouping of one or more access
points). The OmniVista 2500 next generation management suite embeds a
visionary controller-less architecture, providing user friendly workflows for
unified access together with an integrated unified policy authenticati on
manager (UPAM) which helps define authentication strategy and policy
enforcement for employees, guest management and BYOD devices. Stellar
Series APs has built-in DPI technology providing real-time Application
Monitoring and enforcement. The network administrator can obtain a
comprehensive view of applications running in the network and apply
adequate control to optimize the performance of the network for business
critical applications. OmniVista 2500 provides advanced options for RF
management, WIDS/WIPS for intrusion detection and prevention, and a heat
map for WLAN site planning.

3.1 AP Placement & Guidelines
3.1.1 General Recommendations
-Position the APs above obstructions.
-Position the APs vertically near the ceiling in the center of each coverage area,
if possible. APs are designed to be installed vertically, either standing up in a
plenum or hanging from a ceiling, to create the largest coverage area per AP.
Hanging the AP from the ceiling provides the best coverage.
-Position APs in locations where users are expected to be. For example, large
rooms are typically a better location for APs than a hallway.
-Place APs no more than 40 meters apart from each other. Placing APs further
apart almost always results in poor coverage.
-Do not mount APs outside buildings.
-Do not mount APs on building perimeter walls unless the operator wants to
provide coverage outside the building.
-Important: Do not mount AP antennas within one meter (3 feet) of any metal
obstructions. The radio frequency waves from the APs are blocked and/or
reflected by metal objects, such as ducts, conduit, pipes, bookcases, elevator
shafts, stairwells, and walls.
3.1.2 Three Sample Solutions to AP Placement Problems
In the first example, there is a large concrete wall in the middle of one coverage area.

The figure on the left shows a poor installation of two APs indicated with an X. The
figure on the right shows a better solution. Both APs are mounted in hallways. The
leftmost AP is moved to other side of wall to provide coverage on left side of the
wall and the rightmost AP is moved slightly left to provide better coverage to
overlap area.
In the second example, there is a large metal wall next to a planned location.
The figure on the left shows a poor installation of two APs indicated with an X. The
figure on the right shows a better solution. The right most AP is moved to the
hallway slightly to the right of one end of the metal wall. The left most AP is moved
up and to the left to provide better coverage to overlap area.
In the third example, the AP needs to be mounted in a right angle corner of a
hallway.

In the right angle corner of a hallway, mount the AP at a 45 degree angle to the two
hallways as shown in the figure on the right. The Alcatel-Lucent AP internal antennas
are not omnidirectional, and will cover a larger area if mounted this way.
3.1.3 Interferers
802.11b/g/n standards share the unlicensed Industrial, Scientific and Medical (ISM)
band (2.4 GHz) with a number of other wireless technologies. Bluetooth devices and
microwave ovens are the most common ones and can be found on a site where
WLAN will be deployed. AP placement should be chosen in order to minimize
interferences on the WLAN system’s performance. Interferences by WLAN on other
technologies is not discussed, except cohabitation with DECT APs. For more
information, see Cohabitation with DECT APs.
Cohabitation with Bluetooth Devices
Bluetooth technology is based on frequency hopping over 79 channels in the 2400
to 2483.5 MHz band.
There are 3 power classes
-Power class 1: max transmit power: +20 dBm (range 100 m)
oVoice application: do not mount an Alcatel-Lucent AP within 10 meters of a
power class 1 Bluetooth AP. The number of maximum simultaneous calls
on WLAN AP can decrease significantly if a Bluetooth AP class 1 emits
within 10 meters.
o802b/g/n data application: for maximum throughput, do not mount an
Alcatel-Lucent AP within 10 meters of a power class 1 Bluetooth AP.
802.11b/g/n data throughput is reduced when a user within 10 meters
from a class 1 Bluetooth device in use. To ensure 80% of the maximum

Stellar AP | Deployment & Configuration & Troubleshooting Guide 16 |

data throughput, users should be at least 10 meters away from a Bluetooth
class 1 device.
-Power class 2: maximum transmit power: +4 dBm (range 10m)
oVoice application: do not mount an Alcatel-Lucent AP within 1 meter of a
power class 2 Bluetooth AP. WLAN handset users can experience cuts in
the audio when placed less than 1 meter from a Bluetooth class 2 device in
use. Cuts are less than 1 second long and can appear in bursts. General
audio quality is minimally impacted.
o802b/g Data application: for maximum throughput, do not mount an
Alcatel-Lucent AP within 10 meters of a power class 2 Bluetooth AP.
o802.11b/g data throughput is reduced when a user is within 10 meters
from a class 2 Bluetooth device in use. To ensure 80% of the maximum
data throughput, users should be at least 3 meters away from a Bluetooth
class 2 device.
-Power class 3: max transmit power: 0 dBm (range 10 cm)
oNot tested, interferences should be minimal on WLAN.
Cohabitation with Microwave Ovens
Microwave ovens emit signals in the ISM band. Depending on how well the oven is
shielded, emissions can disturb WLAN applications. To reduce interference from
microwave ovens, check the label on the microwave which should provide the
central operating frequency. Most microwave ovens operate at a central frequency
of 2.45 GHz, Emissions occur in a large band, so typically disturb channels 6 to 11. In
this case, an AP close to a microwave oven should be set to channel 1.
Cohabitation with other WLAN APs

Stellar AP | Deployment & Configuration & Troubleshooting Guide 17 |
P a g e
All rights reserved. Passing on and copying of this document, use and communication of its contents not permitted without written authorization from HAN-Networks.
Adjacent APs need to use different radio channels to prevent interference between
them. See Channel and Transmission power Considerations.
Cohabitation with DECT APs
Place WLAN APs at least 3.5 meters from DECT APs in order not to disturb DECT
communications.
3.1.4 Channel and Transmission power Considerations
Adjacent APs need to use different radio channels to prevent interference between
them. The 802.11b/g/n standard provides for three non-interfering channels:
channels 1, 6, and 11. APs within range of each other should always be set to non-
interfering channels to maximize the capacity and performance of the wireless
infrastructure, as shown in the diagram below.
If adjacent APs are set to the same channel, or use channels with overlapping
frequency bands, the resulting interference will cause a significant reduction in the
network performance and throughput, and will degrade overall voice quality.
In an 802.11a/n deployment, all 23 channels are considered non-overlapping, since
there is 20 MHz of separation between the center frequencies of each channel.

Stellar AP | Deployment & Configuration & Troubleshooting Guide 18 |
P a g e
All rights reserved. Passing on and copying of this document, use and communication of its contents not permitted without written authorization from HAN-Networks.
However, since there is some frequency overlap on adjacent 802.11a channel
sidebands, there should always be at least one cell separating adjacent channels and
two cells separating the same channel, as shown in the diagram below.
For voice only applications: do not use the same channel for APs placed less than 3.5
meters from each other. This distance assumes that the AP's transmit power is 100
mW, For an interfering AP emitting at a different power level, the rule is, the
interferer has to be at such a distance that it should not been seen by the system at
more than –40 dBm.
For voice and data applications in 802.11b/g band: do not use the same channel for
APs placed less than 12 meters from each other. This distance assumes that the AP's
transmit power is 100 mW, For an interfering AP emitting at a different power level,
the rule is, the interferer has to be at such a distance that it should not been seen by
the system at more than –47 dBm.
The transmission power of APs can be increased or decreased to provide more or
less AP coverage area. Generally, the transmission power setting should be the same

for all APs in a facility. This minimizes the chance of higher-power APs interfering
with nearby lower-power APs and provides consistent coverage.
It is recommended to set AP power output to 100 mW. If this cannot be
accommodated, use a 50 mW setting or a minimum of 30 mW. With lower power
output settings, special attention must be made to AP placement to ensure there are
no frequency reuse issues. Regardless of the selected power level settings, all APs
and handsets must be configured with the same settings to avoid channel conflicts
and unwanted cross-channel interference.
In mixed 802.11b/g environments, set the power of the 802.11b and 802.11g radios
to the same setting, if they are separately configurable. For example, set both radio
to 30mW to ensure identical coverage on both radios. For mixed 802.11a/b/g
environments, where the AP uses all three radios types, AP placement should first be
determined by modeling for the characteristics of 802.11a, since this environment
will typically have the shortest range. Then, the transmission power of the 802.11b
and 802.11g radios should be adjusted to provide the required coverage levels for
those networks, within the already established AP locations.
Where possible, all APs should be set to the same transmission power level within a
given radio type. For example, set all 802.11a radios to 50 mW and set all 802.11b
and 802.11g radios to 30 mW. It crucial to then set the transmission power of the
handset to match the transmission power of the APs. This will ensure a symmetrical
communication link. Mismatched transmission power outputs will result in reduced
range, poor handoff, one-way audio and other QoS issues.
3.2 Express mode
Stellar APs, by default, are running in “Express mode”. To configure the AP out-
of-box, connect the AP to the network and powered by POE or power adapter, and
ensure the AP could retrieve an IP address from the network.
