MERIDIAN & YOUR WIRELESS APPLICATION
David S. Theodore, Pres. & Wireless WAN Pioneer

If you're considering wireless, but secretly pining for fiber, then let me give you some encouragement. Point-to-point microwave can be every bit as good as fiber; just as secure, just as reliable. The difference is that wireless can't deliver 100 gigabits or terabytes of data, but it's extremely rare that we run into anyone needing that much bandwidth. Yet microwave leaves fiber in the dust when it comes to cost and delivery time.

And speaking of dust, do you know what it looks like under our streets??? Aging cast iron gas pipes routinely crack, notably under older city streets where it's a logistical nightmare to get them out. They leak 10% of all gas into the ground and cause an explosion somewhere, every single day. Truly, read my blog on that! (Those who fear driving over bridges may want to steer clear of manhole covers as well.) We can no longer assume that underground cabling is invulnerable, because it clearly isn't, but we can point to wireless installations that stayed up through Hurricanes Sandy and Andrew.

But if you only take away one point from what I'm saying, consider this. Fiber is a physical medium that works about the same no matter who runs it (within reason), but wireless reliability depends on factors that experienced techs must compensate for - things like distance and terrain, weather patterns, antenna stability, alignment and frequency availability. Therefore wireless results greatly depend on the experience and diligence of your systems integrator ("VAR"). That's where we come in.

WHY TRUST ME?  I literally wrote the book on wireless Ethernet, founding Microwave Bypass in the 1980s and launching the world's first solution (802.3 compliant). Dubbed the "Etherwave Transceiver", it formed the core of the New England Internet and connected world leaders in technology, health care and education. Later, we partnered with Cisco to design the first full-duplex interface and brought Motorola into the business. Our groundbreaking work continues to this day, and if I recommend a radio it's because I've installed it myself and not because we're running a special. If you have a project in mind or some concern, or you just want a straight answer, then email me.

Microwave is a mature technology with a long pedigree, and with the advent of digital radios and today's commoditization, most of the top radios are functionally interchangeable. They're all meeting the same high end FCC specs, and differences between them are relative shades here or there, but hardly as consequential as who you trust with your path engineering, installation and support. Microwave is an engineered solution and the more knowledgeable and experienced your vendor, the better the results.


HELPFUL INFORMATION
Let me give you a quick overview. For starters, if you're looking at point-to-point wireless, then you'll be choosing between two types of "radios". One runs in publicly shared frequency bands (e.g., 2.4 & 5 GHz) and is therefore "license exempt".  You can take it out of the box, set it on your roof and use it the same day. The other uses specially coordinated and licensed FCC frequencies, and there you're waiting 45-60 days for (guaranteed) approval. The wait is worth it though, as I'll explain later.

Is it "wireless" or "microwave"? Of course every radio is "wireless", but to be more specific, ones that transmit between 2 and 38GHz run in the microwave portion of the frequency spectrum and so they're called "microwave". Most point-to-point wireless is "microwave", but when you get to the higher frequencies, the 60-80GHz range, you're in the "millimeter wave" part of the frequency spectrum and those are called "E-band" radios.

What you need to know is that both radio types, licensed and unlicensed, are equally available to you, however there are huge differences between the two - like bandwidth and latency, even cost and implementation time. The type of radio you go with will have everything to do with the amount of bandwidth you need (licensed microwave gives you more), the distance between your sites and whether we need to worry against interference, say in a congested metropolitan area. At Meridian, we're wedded to best solutions, not vendors, and we also know that even the most inspired product selection is no guarantee of performance.

Point-to-point wireless is an engineered solution with exacting tolerances, and so it takes good path engineering and a solid installation to reap the full benefits of any wireless product.  Microwave manufacturers give you their specs from a lab bench, but our job is to factor in your particular environment, accounting for varying terrain, distance and weather, and making sure that the radio performs as well for you as it does on the lab bench.

Our experience and resourcefulness is unmatched and so whether you lease or buy your bandwidth, we'll deliver it on schedule, for a convenient, quality installation that stands the test of time. If you're looking for the most qualified, honest advice then email me and I'll get you started. Hungry for more information? Join my blog.

"HIGH PERFORMANCE" = 1/3 Planning, 1/3 Product & 1/3 Installation
There are some amazing radios on the market and we're proud to bring you the best of them from leading makers like Cambium, Dragonwave & Siklu, but we know as well as anyone, that the performance you get depends on the quality of the implementation (path study, frequency analysis & install). Every performance car needs a good mechanic to make it purr, and that concept is especially true in the microwave business. You can buy a top of the line radio with the best specs, but if you have path reflections or your antenna alignment is a couple of dBs off, then your results will be disappointing. Trust Meridian to deliver optimal performance, regardless of weather, terrain or distance. Want to talk about your application, email me.

PRODUCT SELECTION
We simplify product selection and empower our clients with sound advice and straightforward answers. I don't know about other industries, but in the wireless business, specs are fluffed up like job resumes and a lot of the marketing is flat out misleading (e.g., "aggregate throughput"). Like other things, it's "buyer beware" and so you need to be discerning about who you're getting answers from.



HERE'S MORE ABOUT LICENSED VS. LICENSE-EXEMPT WIRELESS...

Point-to-point wireless outperforms every other type of wireless because you're focusing all the radio energy to a single distant point, rather than scattering it in every direction, like a cellular or Wi-Fi signal. And as I mentioned, point-to-point wireless ("radios") falls into two distinct categories, FCC licensed and license-exempt.

Licensed Microwave ("microwave radio") is the most advanced form of wireless - period. It's what phone companies like Verizon and AT&T rely on - hence the term, "carrier-class", and today there's hardly a large business, hospital, university or government agency that isn't also using microwave. You can spot a licensed microwave installation by its drum-shaped (parabolic) antenna. These systems are heavy-duty and made to withstand the harshest climates. Licensed microwave lasts 15+ years and if money's no object, you can configure a microwave connection to never go down (seriously).

Licensed microwave is as good as wireless gets, but the license part scares many people away. Don't let it. In fact, this type of license is easy to get and you can track your application on the FCC's web site. Once granted, the license is good for an initial 10-year term (extendable thereafter for 5-years at a time) and there are no recurring license fees. The license simply means that you have an exclusive right to a specific, unused set of transmit frequencies between your buildings - nothing more, and so you're never going to see your connection degraded by interference. Virtually any corporate, educational or government entity can get a "Fixed, Point-to-Point" FCC license and turnaround time is about 60-days. For your convenience and assurance, we take care of the application filing and guarantee your approval.

License-Exempt Wireless is the other type of point to point wireless. It's a more economic, scaled-down version that uses smaller, flat-panel dishes and runs in publicly available, shared frequency bands (e.g., 2.4 & 5.8 GHz). These are relatively low in price, super-convenient to deploy and depending on distance, a great answer for bandwidths from 10-150 Mbps.

Meridian Microwave specializes in both licensed microwave and license-exempt, point to point wireless. If you have an application that you'd like us to look at, fill out our quick, 3-question Application Sheet or CALL (781) 413-5661.

COMBINED RADIOS

Where radios are combined onto a single antenna ("dish"), they function as physically separate paths, each with their own distinct frequencies and so short of a building-wide power outage, whatever effects one link has no impact on the other. Therefore, when radios are combined, they act as redundant channels to each other. Switchover is effected by the network switch or router.
