Page 4: Key Features
1.2. Key Features The RWC7100A RF shielding enclosure offers excellent shielding effectiveness of over 100dB within a wide operating frequency range of 400MHz to 6400MHz, so that the effects of external interference are reduced to a minimum. In all interior workspaces, absorber material is attached in order to minimize RF reflections.

Page 8: Performance Test
- RF signal amplifier : capable of sufficiently amplifying weak RF signals, if necessary When measuring the shielding effectiveness of RWC7100A, it is recommended to install a signal generator with a built-in battery inside RWC7100A, and perform the measurement outside of RWC7100A. If a signal is generated from the outside and input through a cable, it is not guaranteed that the test results would be accurate.
Page 9: Test Procedure
4) Set up the signal generator or RWC1020A as follows: - Frequency : 400.1MHz - Power : +10dBm 5) Open the RWC7100A door and measure the power (Pref) moving the reference antenna to several points as shown in Figure 2-3. [Figure 2-3] Check the reference power level (Door Opened)

The recommended operating frequency of the RWC8201A antenna is 700MHz to 8500MHz. When measuring LoRaWAN devices in RWC7100A Shield Enclosure equipped with RWC8201A antenna as an option, it is necessary to measure even in the 400MHz band. Therefore, in this application note, the transfer function of the RWC8201A antenna is measured not only in the 400 MHz band but also in the 900 MHz band.
Page 17 Although the result shows that the loss is larger and the flatness is larger in the 400MHz band than in the 900MHz band, the RWC8201A antenna seems to be good enough to be used in the LoRa Test at the 400MHz band in RWC7100A. RedwoodComm Co., Ltd. |...
