LigoDLB 6 – 20ac

The LigoDLB 6 Series—an extension of the time-tested LigoDLB line of wireless data transfer devices—empowers users
to deliver superb connectivity over 6GHz frequencies. The 6GHz band provides more leg room for all types of wireless
networks, allowing users to find minimally crowded channels, experience less noise and interference, and achieve greater
range and throughput.

Technical Description
Equipped with a 750MHz QCA 9563 CPU, a QCA 9882
radio, and 64MB RAM/16MB Flash Memory, the LigoDLB
6ac brings efficiency to the next level.
The state-of-the-art RF design supports external antennas
over N-Connectors, thus ensuring great output power,
providing improved range, and enabling high-capacity
transmission over 256-QAM.
+500Mbps of throughput—the result of a powerful
hardware platform with an 802.11ac technology-based
radio and the LigoWave iPoll 3 Proprietary Protocol.

iPoll 3: Enhanced Performance
Protocol
LigoWave’s iPoll 3™ PTMP proprietary protocol is an
innovative solution, eliminating transmission congestion
and close-cluster interference created in wireless PTMP
installations.
It works by having a DLB base station poll all connected
DLB CPE within the network, after which the base station
sends a data frame and a token to one CPE, signifying that
it can now send a data frame back to the base station. The
base station then waits for that one CPE to send a data
frame, and only having successfully received it, moves on
to poll all CPE and to perform the same process again.
The iPoll smart polling technology handles the activity of
all connected equipment to ensure transmission efficiency
by having DLB CPE that require less airtime listed as low
activity or idle and having CPE that generate more traffic
assigned to the active list.
This way, iPoll provides improved latency, avoids data
traffic collisions, and allows more CPE to be connected to
the base station simultaneously.

Quality of Service
The LigoDLB series is equipped with Quality of Service—a
technology that prioritizes pre-tagged traffic based
on type to ensure seamlessness and efficiency when
delivering mission-critical data.
QoS sorts through four types of data: network
management, voice, video, and data. Each type is
assigned a priority level, meaning that certain data will be
preferred and given more attention in the network during
data transmission.
LigoDLB 6 devices provide QoS with L2 (CoS)/L3 (ToS/
DSCP) and makes use of the weighted round robin (WRR)
algorithm during the distribution of data, which makes sure
that all types of data are sent in some proportional amount
without packet loss.
