4 M4-2000 point to point system description
This chapter provides description of the Kwikbit M4-2000 system. This includes the system
components, their functions and typical deployment.
4.1 System purpose and key features
The Kwikbit M4-2000 system provides for Ethernet bridge connectivity over a point-to-point
wireless link utilizing Sub 6 GHz spectrum. The system operates as an OSI layer 2 (Data Link)
transparent Ethernet switch, connecting the Ethernet ports between a pair of units with a wireless
data link.
The key features of the system are:
• Operation in NLoS, nLoS and LoS conditions
• High-performance, utilizing advanced Single Carrier FDMA transmission techniques with
adaptive modulation and coding
• Carrier aggregation supporting two radio modules
• Radio options for both licensed and unlicensed frequencies
• Interference management
• Low latency TDD operation: 1ms frame duration
• Dynamic uplink to downlink ratio
• High spectral efficiency
• Ethernet and IP header compression for throughput enhancement
• Out of band management capability through a dedicated Ethernet port
• Compact, weatherproof unit with integrated antenna
• Simple installation, configuration and management with embedded web, SNMPv3, CLI and
syslog
4.2 System components
The M4-2000 consists of a main board and two radio boards. The main board contains an Ethernet
switch device along with the Qualcomm DAN3200 network processor. Each radio employs a MIMO
antenna system with separate horizontal and vertical polarizations. The dual radio system
operates with radio 1 initially connecting and synchronizing link timing before establishing the
radio 2 link.
Once connected, bearer plane data from the data ports is distributed evenly between the dual radio
links.

4.4 Typical system deployment
The M4-2000 system consists of two units, primary and secondary. The two units are identical
hardware and software and differ only by configuration. Configure the units to 10MHz, 20MHz or
40MHz channel bandwidth. The units operate in TDD mode with the primary unit controlling the
link. A typical system deployment would be to provide connectivity between two segments of
Ethernet LAN. These scenarios include:
• Backhaul connectivity to RAN base stations including 3G, 4G LTE and WiFi
• Enterprise LAN connectivity between buildings
• Fiber network extensions
