You’re looking at a pair of first generation SRM6200E radio modems. These two were built in January of 1999. They (the SRM6200E’s) were the first ever long range wireless Ethernet radio modems on the planet. The range was listed at 25+ miles however they were capable of over 60. These came in for repair but I was unable to find anything wrong with them so these 16 ½ year old modems are still running strong.
P.S. The PLR6230 in the background is a fifth generation descendent of these two modems.
