Holland Signal, Inc.

NOTE: As of October 29th, 2001, we Have a Special One-Time offer for Two Aurora 2400's microwave radios T1-E1 and the T1 crossover cable included to connect the Two MSA 100 Mux to the Radio.  These radios were used for test and only have one or two hours on them. The two Aurora 2400's have been completely checked out for operation.  Price is $4000 for each Aurora 2400 and $1800 for each MUX unit.

The Entrata MSA 100 family is designed for small and large businesses and organizations that utilize either a single office or multiple branch offices.  By integrating a router, CSU/DSU, channel bank, and drop and insert cross connect functionality in a single device, access services can be supported on the same platform,, and customers can select their desired services by using software that allows for quick remote upgrades and initial capital investment protection.  In addition, the product provides analog support for up to 24 FXS or FXO channels, optional compression modules, Voice Activity Detection(VAD) and a wide variety of voice services including Voice over IP (VoIP).

See right below the displayed pictures, the Pricing Tables and Portable Document Files (PDF's) for ordering either the Aurora 2400 or 5800 Microwave Radios.   There are also Data Sheets in PDF format for these models that you can view and print if you like.

Aurora™ is a family of point-to-point digital microwave radios employing spread spectrum technology. These radios offer T1/E1 wireless service for line-of-sight distances covering approximately 50 km or 30 miles. Aurora radios operate in the ISM bands of 2.4 and 5.8 GHz and provide ideal wireless interconnection for private wireless access, Internet service, LAN/WAN, cellular and PCS/PCN systems.

2.4 GHz Antenna Selection
A low-cost grill-type rectangular parabolic grid antenna with about 24 dB gain is standardized with the Aurora 2400.

However, a large selection of other 2.4 GHz antennas with higher gain (up to 15ft/4.7m dishes with almost 39 dBi gain!), lower gain, panel, helix, wide beamwidth, etc. as well as other standard round aperture grid and solid dishes are also available for deployment in Aurora 2400 links Low-gain (e.g. 18 dBi) 2.4 GHz circularly-polarized helix antennas may be deployed on over water paths to greatly reduce fade depths from specular multipath reflections. However, the cross-pol discrimination between linear V- or H-pol and circularly - polarized signals is only 3 dB, so use appropriate caution in deploying helix Antennas in congested areas.

Even though the transmitter power output may be lowered to accommodate regulatory rules, larger antennas are recommended on the longer fading Aurora 2400 hops. The higher antenna gains will apply to the receive (“non-regulated”) end of the path for more fade margin and reduced outage. + 92,  dB. The receive signal level (RSL) and fade margin (to the -92 dBm 10-3 BER outage point) on this 19 mi link (130 dB path loss) is thus computed as -60 dBm and 32 dB respectively.

This provides a 99.99934% path reliability (~200 SES/yr outage) in this good propagation area (geo-climatic factor c = 1; t = 50)
