Recommended Antenna Separation
The recommended antenna separation is related to the band frequency/wavelength. To
accommodate the shortest frequency/longest wavelength band supported by the RV55,
Sierra Wireless recommends a minimum antenna separation of 214 mm for best results,
and if necessary, a separation of 107 mm for acceptable results.
Step 4—Connect the Data Cables
The RV55 router has the following ports for connecting data cables:
•
(Micro-AB)
•
(RJ-45)—Use a Cat 5e or Cat 6 Ethernet cable
•
(9-pin RS-232)
