System Overview:
Each enet100 transceiver is configured as a node on your wireless network. In the most basic
configuration, two enet100 wireless routers can be connected as a point-to-point link. More nodes can
be added to form a CPTP or ring network that greatly increases greater reliability with self-healing
capability. Should one of the links on the ring fail, traffic can be routed the other direction with loss of
service. For even greater reliability, points on the CPTP network ring can be interconnected in a mesh
configuration. Not only does the mesh configuration increase reliability to tolerate more than one link
failure, traffic can be dynamically re-routed over the least congested path.

Each wireless router or wireless network node has two main components; an indoor Digital Processing
Unit (DPU) and an outdoor Microwave Processing Unit (MPU).
Unit (DPU) and an outdoor Microwave Processing Unit (MPU).
The DPU has a single Fast Ethernet connectoin that connects your wireless router to the outside world.
Through the RJ-45 connector, the system is configure initially as well monitored and maintained while
in operation. As Fast Ethernet data from your network is received by the Enet100 router, the DPU buffers
it, adds Reed-Solomon forward error correction (FEC) and modulates the data onto an RF carrier using
quadrature-amplitude modulation (QAM). The system uses modulation rates up to 128QAM with
concatenated Reed-Solomon FEC for excellent bandwidth efficiency and data integrity.

Initial setup of the DPU for each specific application is performed with local computer and null Ethernet
cable. This can be done on site or prior at another location. The Enet100 is menu-driven and offers
virtually “plug-and-play” capabiliuty. After setting up the IP address, and aligning the antennas, the
system is up and running. All access to the enet100 wireless router is via a standard web browser
(Explorer, Netscape, etc.) as the GIU interface. Aside from the basic setup parameters, myriad other
functions can be controlled such as QAM rate, baud rate, data payload, Reed-Solomon overhead, IP
address and static IP routing tables to name a few. Optional routing protocols such as RIP1-2, OSPF,
and BGP/EGP are available for additional router functionality.

After initial setup, and the unit is in service, administrators with the proper authority can access router,
view performance parameters, upgrade software and make setup changes via the local network or
through the Internet using the DPU’s unique IP address. All software upgrades are free to Enet100
users and can be downloaded from the enet100.com website and sent directly to the DPU from a remote
location.

High water marks can be set as alarms on a number of parameters. As examples, if payload falls below
a specified point, the DPU can be programmed to route data through another path, or if BER exceeds
a predetermined threshold, a technician is paged.

A single coaxial cable carries the transmitted signal, received signal and power between the indoor DPU
and outdoor MPU. The transmit section of the MPU uses a very low-noise processor to upconvert the
RF signal from the DPU to the desired microwave frequency. After upconversion the signal is filtered and
amplified for transmission. The receive portion of the MPU uses low noise amplifiers to boost the
received signal and then downconvert it to an RF frequency for the DPU. The MPU determines the final
operating frequency and is offered in a wide range of licensed and unlicensed frequency bands from
6MHz through 38GHz.
