Frequently Asked Questions On OTDRS And Hints On Their Use
OTDRs, also known by their technical name optical time domain reflectometers, are valuable fiber optic testers when used properly, but improper use can be misleading and, in our experience, lead to expensive mistakes for the contractor. We have been personally involved in several instances where misapplication of OTDR testing has cost the contractor as much as $100,000 in wasted time and materials. Needless to say, it’s extremely important to understand how to use these instruments correctly.

• Proportional Scheduler

I struggled with a title for this post for a bit. I am aiming this at those WISPs who have been in business a bit and are looking for those products to take them to the next level. Maybe you started on a shoestring budget and need to “step up your game”. Maybe you were recommended a product and want to see what else is out there. I have compiled the following list of vendors at the WISPAMERICA 2020 show that you should spend some time talking with. The following list is not all of the vendors to talk with by any means. These are just some of the ones I would not miss and have some in-depth conversations with for those younger WISPs. Maybe you need a billing software, or better antennas, or automation.
In no particular order
If you are doing LTE or small cells. Antenna manufacturer.
Add on Services
Voice and unified communications.
ISP and carrier billing
Texas-based distributor of many lines
Chicago area-based distributor of many lines
Wireless manufacturer of point-to-point and point-to-multipoint gear as well as in-building wireless
Makers of horns and other antennas to help mitigate noise.
RF mapping and path analysis for wireless links
Tower One Inc
Training and safety certification for your tower and climbing needs
This is not a complete list by any means. These are companies I have first-hand knowledge of their product or service. If you would like to see your company listed for the upcoming WISPAPALOOZA 2020 contact me, find me at the show, or become a sponsor of this blog.
An interesting post about DD-WRT crossed my inbox awhile back. Like most interesting things I saved it to look at later.
Custom firmware, such as DD-WRT makes the process easier, and provides you with a lot of additional options as well; thereby turning a standard $100 router into a super router that is suitable for any home or office.
With this DD-WRT router guide you’ll be increasing your wireless range, data transfer rates, creating NAS solutions, setting up a VPN Service, and so much more in no time at all. Some of these, you can even implement without having DD-WRT.
Don’t have the time to read all of this today? I’d recommend at least reading the introduction so you can find out what this “DD-WRT” business is all about.
After testing samples of Monoprice’s CMR (riser) cable, UL stated that the cable may pose a fire hazard and recommends that organizations discontinue using it. In a public notice, UL said Monoprice’s CMR cable “may pose a fire hazard … does not comply with UL’s safety standards and is not authorized to bear the UL mark for the United States or Canada.
