Radio Frequency Interference Requirements
This device complies with Part 15 of FCC Rules.
Operation is subject to the following conditions:
1. This device may not cause harmful interference.
2. This device must accept any interference received, including
interference that may cause undesired operation.
3. This device should not be co-located or operating in conjunction
with any other antenna or transmitter.
Interference Statement
This equipment has been tested and found to comply with the limits for
a Class A digital device, pursuant to Part 15 of the FCC Rules. These
limits are designed to provide reasonable protection against harmful
interference when the equipment is operated in a commercial
environment. This equipment generates, uses, and can radiate radio
frequency energy and, if not installed and used in accordance with
the instruction manual, may cause harmful interference to radio
communications. Operation of this equipment in a residential area is
likely to cause harmful interference in which case the user will be
required to correct the interference at his own expense.
However, there is no guarantee that interference will not occur in a
particular installation. If this equipment does cause harmful interference
to radio or television reception, which can be determined by turning
the equipment off and on, the user is encouraged to try to correct the
interference by one of the following measures:
 Reorient or relocate the receiving antenna.
 Increase the separation between the equipment and receiver.
 Connect the equipment into an outlet on a circuit different from
that to which the receiver is connected.
 Consult the dealer or an experienced radio/TV technician for
help.
FCC Caution: To assure continued compliance, (example – use only
shielded interface cables when connecting to computer or peripheral
devices). Any changes or modifications not expressly approved by the
iii

Configuration Guide
party responsible for compliance could void the user’s authority to
operate this equipment.
Warning
The user is advised to keep apart from the base-station and antenna
with at least 45cm when the base-station is in operation.
Please install a lightning arrestor to protect the base station for lightning
dissipation during rainstorms. Lightning arrestors are mounted outside
the structure and must be grounded by means of a ground wire to the
nearest ground rod or item that is grounded.
A8n (ac) product series require professional installation. The installer
shall be responsible for ensuring that the proper 5GHz antenna is
employed so that the limits in FCC Part 15.247 are not exceeded. The
installer is responsible for ensuring that the 5GHz radio is used exclusively
for fixed, point-to-point operations.

1. Introduction
This guide covers the initial configuration of Altai A8n (ac) Series Super
WiFi Base Station via Web Administration Interface (Web UI). Web
Administration Interface (Web UI) is the built-in and user-friendly graphic
interface on all Altai A8n (ac) Series products. It allows you to
configure, monitor, and manage the devices using web browser.
Mozilla Firefox, Google Chrome, and Internet Explorer 8+ are
recommended.
This guide is applicable with firmware version 2.0.1.6 or above for
hardware platforms with the following models:

2.4. Secondary IP Address of A8n (ac) Series
Products
The default IP address of A8n (ac) series products is 192.168.1.222/24.
A8n (ac) series products support a fixed IP address on the Ethernet
connection called Secondary IP Address. This secondary IP address is
192.168.99.x/24 where x denotes as the decimal value of the last byte
of the Ethernet MAC address on the access point.
Example 1:
Device Ethernet MAC address: 00:19:BE:20:03:8C
Secondary IP Address of this device:
192.168.99.140 (8C (HEX)  140 (DEC))
The secondary IP address uses IP range from 192.168.99.5/24 to
192.168.99.254/24. The rest of IP addresses are reserved. If the last byte
of a MAC address matches any of the reserved IP addresses, the
supported device shall follow the MAC to IP address mapping shown in

Configure WLAN with WPA / WPA2 / WPA-auto Authentication
WPA (Wi-Fi Protected Access) or WPA2 provides enhanced security
over WEP, and allows client authentication based on an external
authentication server such as a RADIUS server, for corporate networks.
WPA-auto is a mixed security mode which supports multiple
implementations of the WPA standard, such as WPA and WPA2.

client’s capabilities
TKIP - This algorithm provides greater compatibility with older client
devices, but is not supported by the 802.11n standard.
AES - This algorithm provides enhanced security over TKIP, and is the only
encryption algorithm supported by the 802.11i standard.
If Authentication Mode is WPA2:

Safe Mode is for detecting the backhaul link integrity. If the AP loses its
backhaul connectivity, it forces the clients to re-associate with another
AP by changing its SSID to a default Safe Mode_X, where X is the MAC
address of the radio interface in hexadecimal.
This action can protect the client from connecting to the AP which has
no backhaul to the Internet end. Total duration for AP from losing
backhaul link to safe mode is 3 x ping interval seconds.
Note:
- A8n (ac) recovers itself from safe mode if it detects the
backhaul link is recovered

2. Select suitable mechanism on Protection Mode; you can select:
None - no protect mechanism is used. It is the default setting.
CTS-only - also known as CTS-to-Self; AP issues a CTS frame to itself
before sending data. All clients will not transmit during the time.
RTS-CTS - AP sends a RTS frame, waits for the clients CTS frame and
then sends the data packet. It allow more robust operation, but at
the expense of additional overheads.
3. Specify frame size in byte between 0 and 2347 bytes on RTS/CTS
Threshold; 2346 is default setting.
If a frame is smaller than the RTS/CTS threshold, it will be sent by the
AP without modification. If a frame is larger than the RTS/CTS
threshold, then two frames will be sent by the AP. The first frame is an
RTS (request to send) frame. After the RTS frame is sent, the AP listens
56
Altai Technologies Ltd. All rights reserved
Altai A8n (ac) Series Super WiFi Base Station
Configuration Guide
for the corresponding CTS from the target client. Upon reception of
the CTS, the AP then sends the data frame. There are trade-offs
when considering what value you should set for the RTS/CTS
threshold. Smaller values will cause RTS to be sent more often,
increasing overheads. However, the more often RTS packets are
sent, the sooner the system can recover from collisions. It is
recommended to use the default value or only minor reductions of
the default setting.

Enable IGMP Snooping
AP is a Layer 2 device when it is configured as Switch mode. However,
IGMP Snooping implementation on AP is a little bit different than that of
standard Layer 2 Switch.
Each Virtual AP (WLAN) port is similar to a Layer 2 switch port. With
IGMP Snooping enabled in the AP, clients associated to a VAP will only
receive multicast packets if there is at least one client joined the
multicast group in that VAP. Unlike ordinary IGMP Snooping
implementation, where Layer 2 switch converts multicast to unicast
and delivers them to devices registered with the multicast group, AP
should simply send out the multicast packets from the VAP which has at
least one client joined the multicast group. This is done because the
wireless media is a broadcast media. It does not need to be sent
multiple times when there are more than one registered clients.
When IGMP Snooping is turned on, multicast packets should be
dropped at the VAP exit if there is no client from the VAP who has
joined the corresponding multicast group.
The IGMP snooping forwarding table (port and multicast MAC address
mapping table) should support aging mechanism to age out the entry
which has no multicast traffic for a period of time.
