Figure 17 shows the top-level block diagram. Lite includes 6 function modules, including
• Frame processing module (switching, QoS, radio frame processing);
• Control function (TPC/ACM/DCS/DFS/Retransmission) processing module;
• Power supply module;
• IEEE 1588v2 processing module;
• Baseband and RF module;
• Antenna.

5.1 Packet Processing Module
The packet processing module provides the following functions:
• Packet switching;
• QoS mapping and scheduling;
• Frame fragmentation and aggregation;
• MAC frame encapsulation.
The packet switching unit switches traffic between an Ethernet port and a radio port, and
also performs VLAN manipulation.
The switch can be done based on port or on MAC learning. Lite supports up to 48 VLANs
switch.
The QoS mapping and scheduling unit maps the QoS class for different traffic and imple-
ments strict priority or WRR/DWRR scheduling to provide different SLA for different
traffic classes.
The frame fragmentation and aggregation unit support aggregates different packets into
the same MAC frame to better utilize the radio bandwidth and fragments packets that
