A. GENERAL CONTRACT INFORMATION: Provide service consisting of the following tasks.

a) Background:

To perform research on modern wireless networks, NRL plans to refurbish an existing anechoic chamber located at the Naval Research Laboratory in Washington DC.

Wireless networks operate worldwide between 500MHZ and 60 GHz. The resultant chamber shall support operation over this frequency range.

b) General Description:

The Anechoic Chamber being refurbished is a rectangular chamber approximately 40’L x 17’W x 17’H. This chamber is equipped with a movable wall located at the east end of the chamber and two quiet zones located adjacent to both the moveable east wall and the fixed end wall at the west end of the chamber. The chamber quiet zones are 4’ x 4’ x 4’ cubical volume. The planes containing the surfaces of this cube are parallel to the plane containing the walls, ceiling, and floor of the chamber. The center of the quiet zones are located on the chamber boresight axis and two feet from the absorber tips on the fixed end wall. In both the east and west walls, there are personnel access doors.

Next to the quiet zone on the west wall, a section of the wall will swing up to allow large objects to be placed in the chamber.

Figure 1: Chamber layout with approximate task locations.

c) Task Overview: Provide all necessary labor, equipment, parts and supplies to:

• Redesign the Anechoic Chamber Absorber layout to support testing of wireless devices and networks over the frequency range of 500MHZ to 60GHZ maintaining the existing 4ft Cubic Quiet Zones at each end of the chamber and providing a solid, walk-on, absorber surface over the entire floor. The design shall include an option such that a transmitter could be installed in the center of the chamber adjacent to the south wall with two separate receivers, each located in the center of the quiet zones adjacent to the two end walls. The minimum reflectivity in the quiet zones shall be -20 dB with the ideal reflectivity of signals within the defined quiet zones shall be <= -50 dB as per IEEE Std 149-2021 Section 4.0. A draft submission of the chamber absorber design layout with expected reflectivity levels within the quiet zones shall be included with the cost proposal.

1 Requirements

1.1 General Description

The Anechoic Chamber is a rectangular chamber approximately 40’L x 17’W x 17’H. This chamber is equipped with a movable wall located at the east end of the chamber and a two quiet zones located adjacent to both the moveable east wall and the fixed end wall at the west end of the chamber. The chamber quiet zones are 4’ x 4’ x 4’ cubical volume. The planes containing the surfaces of this cube are parallel to the plane containing the walls, ceiling, and floor of the chamber. The center of the quiet zones are located on the chamber boresight axis and two feet from the absorber tips on the fixed end wall. In both the east and west walls, there are personnel access doors. Next to the quiet zone on the west wall, a section of the wall will swing up to allow large objects to be placed in the chamber(Figure 1). The original chamber design was to cover the frequency range of 2-40 GHz. Table 1 provides the “As-Built” reflectivity of the existing quiet zone. These Legacy chamber characteristics are provided FOR REFERENCE ONLY.

2.2 Room B: Anechoic Room

2.2.1 Remove and replace RF absorber in Room B.

The contractor shall remove and dispose of, following all state and local environmental guidance accordingly, all existing RF absorbing material from the floor, walls, and ceiling while replacing with new absorbing material.

The RF absorber shall have optimal attenuation across 500 MHz – 60 GHz or greater.

The RF Absorber shall be able to withstand 50 Watts Continuous Wave indefinitely.

The RF absorber shall be installed in a geometry optimal to re-establish quiet zones on the two end walls. In addition, the design shall include an option such that a transmitter could be installed in the center of the chamber adjacent to the south wall with two separate receivers, each located in the center of the quiet zones adjacent to the two end walls. The minimum reflectivity in the quiet zones shall be -20 dB with the ideal reflectivity of signals within the defined quiet zones shall be <= -50 dB as per IEEE Std 149-2021 Section 4.0.

The RF Absorber shall be self-extinguishing, and sufficient material shall be applied to provide the reflection levels as specified in the approved design. The RF absorber material shall meet the requirements of NRL 8093 Test Nos. 1, 2, and 3.

There is one air vent in the north wall of the anechoic chamber. The air vent shall be maintained such that it provides adequate air supply and return to change the air sufficiently enough to maintain room temperature. The air vent shall not degrade the RF Chamber effectiveness.

The contractor shall install walkway absorber on the entire floor to enable best possible performance in the two quiet zones.

2.2.2 Repair power sliding personnel door between Rooms A and B.

The primary access door into the Anechoic chamber is via the west control room. This door is approximately 3’w x 8’h and is pneumatically controlled. It is currently in disrepair.

This personnel door approx. 3’w x 8’h, slides on tracks into the chamber. The contractor shall restore this door to proper operation.

2.3 Room C: East Control Room

2.3.1 Moveable wall between Rooms B and C.

The east wall of the chamber, approx. 14’w x 14’h, has the capability to move thru the use of a hand crank located on the south wall of the east control room. For the absorber redesign, the wall does not need to retain the ability to move. Currently, since the wall was designed to move, the entire floor of the East Control Room is composed of walk-on absorber.

3 CDRL Documentation
