Wireless Backup is a Bridge Over Troubled Water for your Corporate IT Network

Another "Inconvenient Truth." Your Corporate Network Needs a Wireless Backup

Weather extremes are overwhelming our systems. Storms and floods "never before seen," are happening in places never before imagined. Three years ago it was Hurricane Sandy that knocked out a huge swath of Manhattan and New Jersey. Now parts of South Carolina are reeling from what has been called a "1,000-year flood."

When extreme weather hits, it often takes with it aging infrastructure, collapsing roads, bridges and dams. This is a new dynamic in our lifetime, one that means girding up for rough seas - like we may have expected once in a generation, only now epic weather events are becoming commonplace. If our buildings and public ways are to be battered like ships on the ocean, businesses will need to become more seaworthy. That means building resiliency to minimize setbacks and bounce back to normal operation.

I Tell You, Wireless Backhaul Gets No Respect

wireless backhaul for buyers and sellers

One of my first purchase orders came in 1988 for a link between Mass General Hospital and Harvard Medical School. I was delivering the world's first point-to-point wireless solution for Ethernet, and though it was my design, I knew very little about microwave. After the install, I sweat bullets every time a thunderstorm rolled through, waiting for a 2 a.m. phone call to say that my link brought the hospital's network down. Instead of celebrating a sale to Boston's most preeminent institutions, I was filled with anxiety.

Want to know what happened? Nothing. The link didn't fail once in the eight-plus years it was in service - not from rain or snow, wind or solar flares, not from the recession of 1990, cows farting or the collapse of Communism. And since then, I can tell you that the technology has only gotten better.

After that job we got some good publicity and lots of phone calls. Unfortunately most of them started like this, "Our consultant says that microwave goes down in rain... I understand that snow effects the signal... I hear that exposure to RF energy may be hazardous to our employees... I read somewhere that all the frequencies are taken up," etc., etc., etc. Okay, so I learned that the phone company - who was buying microwave by the truckload, was scaring the bejesus out of anyone else who might want it. I trusted that time would shake out all these misperceptions...

Bargain Shopping for Wireless Backhaul?

Avoid bargain shopping for wireless backhaul.
I go way back in the point-to-point wireless (microwave) business, having developed the first wireless Internet technology, followed by a string of other firsts and thousands of customer applications. Now given what I've seen, I need to say something about pricing to IT buyers in the enterprise community.

"Resist the urge to bargain shop for wireless backhaul. These days you can buy a PTP link for a song, but though the song seems appealing, it will make your ears bleed."

There are things in life that you can economize on, and others that you wouldn't think that way about. For instance, my son is a lacrosse goalie and when it comes to his helmet and pads, I'm not interested in "a great deal" on protection. I'm looking for the best they've got, and if it's more expensive - within reason, then I'm not ashamed to say that I gain a little confidence in that. And what about finding a surgeon? I've never heard anyone brag that they've found the cheapest one. What you want is a surgeon who's performed the same operation (over and over) on professional athletes and U.S. Senators. 

A corporate data backbone is a main artery of your business, its lifeblood. It's something where you want to know you've got the best of everything - best radios, best installers, best support. Nothing but the best, baby!

Averting a Titanic IT Outage from Underground Cable Destruction

Vulnerable Underground Fiber Calls for Wireless Mixed Media Backup

You’re the captain of your corporate IT ship. You’ve thought it all out - your routes, requirements and resources, and you prepared for the worse by spreading your network out to different carriers. You even have different fiber routes so that if one fails you have the other. But are you really protected?
When your carrier tells you that they’ve got back ups to back ups and they’re (statistically) never going down, can you believe it? From what I’ve seen, I wouldn’t. Carrier outages happen more than we think, and while they’re hardly publicized, call some of your IT colleagues and ask if they ever lost a connection to their carrier or Internet provider.
I figure that Bloomberg must have the best IT safeguards anywhere, but their network crashed anyway. We don’t know what caused it, but no doubt those folks stayed up endless nights working to prevent such a disaster. But it still happened, and I wonder what stone was left unturned that might have mitigated the damage.
In a similar vein, I wonder how “mixed media backup” dropped from the telecom vernacular. It was a popular phrase in the 90's (pre-Google), and what it meant was that - as a policy decision, whatever terrestrial lines you had were backed up over the air (using point-to-point microwave). What makes more sense than that? Yet it’s far from common practice these days, even as IT managers lose sleep thinking of ways to plug network vulnerabilities.
