Actually it IS the hardware thats end of life. After a set date, there is NO support on it so if there is a software vulnerability, there will not be any patches to correct it. End of life doesn't mean it stops functioning, it means you can no longer replace it with a like part, nor patch or upgrade it. The AP is not like a hard drive or an old computer that just runs til it quits, though, older computers can only run OS up to a certain point and are no longer supported so if your PC cannot run windows 10 and is stuck on XP it is extremely vulnerable to being hacked with Malware or Ransomeware. IOW do not do any financial work on it!re: The 3G and 4G non HD networks are being retired as the hardware is reaching end of life. This is very normal with computerized hardware.
It's NOT the hardware that's 'end-of-life' rather they can't squeeze any more pennies from the clients,plain and simple.
I have several computers here STILL running on 170MB SCSI drives from the mid 80s. Have 4 laptops still functioning as well as TRS80 MIII with 15MB HD, 'up and running', so now it's NOT the hardware.
I also have a networked energy management system from the 70s that has never,ever been hacked unlike the new stuff.
Also keep in mind these are in an outdoor environment and subject to many different hazards like high winds, UV damage, lightning and water intrusion, so they fail constantly and need to be replaced. Once new old stock is used up, thats it, no more. The 3G hardware is 20 years old, far older than most routers and switches in use today, average lifespan of a router or switch or PC for that matter is 10 years.
I used to work for a wireless ISP and have climbed some pretty damned tall towers, a 400' tower is no joke. I have had to replace a few burned out AP's 400' in the air, and what's the worst part is having to replace scorched cables, they get friggin heavy by the time the end is up by the AP. That and a tower can only have so many AP's or antenna on them for wind load reasons, so to provide more coverage, older smaller radius AP's have to go. By removing the old 3g/4G non HD radios, they make room for further reaching higher speed ones.
