BWIN™ - Broadband Wireless Internet Network

BWIN™ Broadband Wireless - 2.5 GHz MMDS

Base Station

A DOCSIS® CMTS is used to bridge the Ethernet LAN (connection to the Internet) to the 2.5 GHz MMDS wireless system at the base station. The main active components of the 2.5 GHz MMDS base station are the MA4367 MCS Transmitter/Upconverter System and the HDC2100 2.1 GHz Downconverter. The MA4367 system includes a chassis, power supply/controller, MA4061B Upconverter and MA4070C Power Amplifier.

The MA4367 is the main interface from the DOCSIS® CMTS and the wireless network. The downstream signal originating from the CMTS is sent to the MA4367 for upconversion into the 2.5 GHz band and amplification on its way to the antenna for transmission to the susbcribers. Upstream signals received from the subscribers over the wireless link are sent to the HDC2100 for downconversion prior to entering the CMTS.

Subscriber

The TR2126C or TR2126SE subscriber transceiver serves to frequency translate and amplify the upstream and downstream signals to the appropriate cable frequencies for use by an indoor DOCSIS® cable modem. A single low cost 75 Ohm cable (i.e. RG-59 or RG 6) is used to connect between the transceiver IF port and indoor AC/DC power inserter. A short jumper cable is used to connect to the cable modem. The cable modem serves to provide two-way broadband Internet access to the local PC's or LAN via either an Ethernet or USB connection. Recommended cable modems depend on the application.

Network Management

The MHM-MSM Server and provides system operators with comprehensive tools to operate and manage BWIN networks from Vecima Networks.

The centralized design of the Microwave History Manager [MHM] simplifies many common maintenance and administration tasks by allowing password protected access for qualified personnel to view and configure crucial network parameters from either in the field or at the office. MHM also provides a vital tool for Vecima Networks to provide remote assistance to its customers and guarantee end-user satisfaction.

The Microwave Subscriber Manager [MSM] expands on the basic MHM by adding functions for complete subscriber station provisioning that allow the system operator to create and administer custom subscriber service packages (i.e. Gold, Silver, Bronze) based on downstream/upstream data rates and priority. These policies are assigned directly to each subscriber station on the BWIN network.

All MHM and MSM transactions take place in a secure environment using HTTPS or SSH which are proven data encryption technologies.
