WMS 4000 1-CHANNEL SETUP

EXAMPLE: 1-CHANNEL SYSTEM FOR SPECIFIC ARCHITECTURAL REQUIREMENTS

“The devil is in the details” is a saying that is very often true of wireless systems. Even if multichannel setups are no problem for the WMS 4000 thanks to frequency programs, Auto Setup etc., situations will arise where the greatest problem is not the number of channels but the correct design of a system with just one channel. Specific architectural conditions do not call for cutting-edge tech- nology but rather for ingenious antenna posi- tioning and the availability of small and helpful additional components required for a well-conceived system.

In this example, we needed a single-channel wireless system for a three-story reinforced- concrete building with an L- shaped plan. The task sounds simple: the transmitter must deliver a signal from any place on each floor.

The only wqay to solve this problem is to use long antenna cable runs and booster anten- nas. The latter are simply suspended from the ceiling at the junction between the two wings of the L-shaped plan. It is essential to pay attention to the layout and the distances between the antennas. Antenna combiners

connect the antenna cables from each floor to the receiver.

However, the cable runs to the last floor are too long for the receiver to supply enough power to the booster antennas. This problem can be solved by inserting an ASU 4000 remote feeding adapter and power supply into each antenna cable. The ASU 4000 is available with AC power supplies for a variety of AC voltages. A simple, inconspicuous and cost efficient solution that minimizes the number of required components.

ASU 4000 Remote Power Supply compensates for power drain of long antenna cables

The ASU 4000 is a small but ingenious accessory for ex- tremely long antenna cable runs. It comes with a power supply for one of four AC voltage ranges that allos the device to used in virtually every country. The compact dimensions and the rugged, splash-proof metal case make it the first choice for open-air applications.
