The Next Decade of Bandwidth - Part V

Wireless is the bandwidth service that gets most of the press these days, but there are big developments afoot in the wired world as well. We’ll wrap up our look into the next decade of bandwidth with what’s going on with copper and fiber optic services.

It’s no surprise that fiber optic networks are expanding. Some of this expansion is prompted by American Reinvestment and Recovery Act that appropriated $7.2 billion to expand broadband access across the country. Rural areas that have been largely ignored by commercial interests are especially targeted. With funds available for middle-mile fiber runs, competitive carriers are taking advantage of the opportunity to expand their networks.

While fiber is being trenched through the countryside to provide broadband delivery to Wireless Internet Service Providers (WISPs) that serve sparsely populated areas, even more fiber is being routed through metropolitan areas to hookup businesses of all sizes. Government incentives aren’t needed here. Businesses hungry for increased bandwidth either foot the bill for hookups to metropolitan fiber networks or commit to service levels that justify carriers to “light” their buildings for fiber service.

Why the interest in fiber optic connections? It’s not just mobile bandwidth that’s straining at the limits. T1 lines may have been all the bandwidth a small or even medium size business needed to handle email, general web browsing and communication with its website servers hosted elsewhere. Now, 1.5 Mbps seems a bit quaint and inadequate for all the smallest operations. What drives business now is cloud connections, Software as a Service, video conferencing, hosted VoIP and other bandwidth demanding applications.

The transition from 3G to 4G wireless also means that cellular carriers themselves are strained for fast enough backhaul connections. T1 lines works great to connect towers that handled voice calls. When users expect 10 or 15 Mbps of broadband service, fiber optics look like the ideal solution. The cost of construction, once a show stopper, becomes another part of the upgrade investment that’s paid once and offers almost unlimited upgrades for future needs.

Cloud computing is a major attraction for many businesses who find that pay-as-you-go is much easier to justify than requisitions for million dollar data center improvements. No need for racks and racks of servers, the environmentally controlled building to house them, the backup power generators, or the round-the-clock technical staff to keep everything running smoothly. Outsourcing that to a cloud service provider gets rid of those headaches, but adds a new one. How to you connect to the cloud? Low bandwidth, high latency connections will bring your operations to a grinding halt. What you need now is high bandwidth along with low latency, jitter and packet loss as a backbone to your virtual servers on the other side of the country. That means fiber optic lines and probably two of them for redundancy.

Fiber technology hasn’t been static during this expansion. Until recently you had a choice of SONET services from OC3 to OC12 and perhaps OC48. That was it. Now, Ethernet over Fiber is coming on strong as a direct competitor. Carrier Ethernet more closely matches the LAN networks that feed it. It is more scalable to meet changing business needs. Best of all, Ethernet services tend to cost less, often considerably less, than equivalent SONET fiber optic services.

But, wait! The era of copper is far from over. Just when carriers were thinking about decommissioning their twisted pair copper to let it corrode in the ground or be sold for scrap, Bonded T1 and Ethernet over Copper gain favor as business bandwidth options. While a single T1 line may be too constrained for many uses, multiple T1 lines can be bonded into a single larger bandwidth service up to 10 or 12 Mbps. Ethernet over Copper (EoC) technology uses the same twisted pair bundles as bonded T1, but a more advanced modulation scheme. EoC bandwidth is distance sensitive, but can easily deliver 10 or 20 Mbps to most businesses and 30, 50 or even 100 Mbps for short runs. Continuing development incorporating wireless techniques such as MIMO (Multiple Input, Multiple Output) for crosstalk cancelation is pushing the limits of copper into the hundreds of Mbps and even to a fiber-like Gigabit per second bandwidth.

The next decade of bandwidth is likely to be dominated by massive fiber optic build-outs for fixed locations, such as office and industrial parks, along with copper solutions to bridge the gaps where fiber doesn’t yet connect. Wireless is clearly headed for a common 4G LTE nationwide infrastructure. Compatibility will be built into portable and mobile devices, perhaps as prolifically as WiFi is now. There may be some surprises in store, such long range and interconnected WiFi hotspots or whitespace transmitters as wireless competitors, high bandwidth satellites covering rural areas better than spotty fiber and cable construction, and the development of much higher microwave frequencies (60 GHz and above) and even infrared mesh networks as new service options.

I hope you’ve enjoyed this speculative look into what’s likely to happen in the next 10 years or so, as our appetite for higher bandwidth Internet and private network connections demand satisfaction. There are many good options available right now to support your current business needs. You may not even be aware of how much development has been going on in your area to increase service levels and reduce costs. This would be an excellent time to get competitive options and quotes for business bandwidth services.

This has been a 5 part series on bandwidth. If you’ve missed any part of it, you can access Part I, Part II, Part III, or Part IV to catch up at any time.

Internet Wholesale Bandwidth Options

There are two types of organizations that buy Internet bandwidth. Most are end users. They want the access for their employees. The others are resellers. They take large Internet connections and divvy up the bandwidth to hundreds or thousands of individuals and businesses. These are Internet Service Providers (ISPs) looking to buy at wholesale and sell at retail.

The largest networks in the world, called Tier 1, don’t purchase Internet access. They are part of the core network itself. Those major world wide networks exchange traffic on basis of equals called peering. Each network gets as much traffic as it sends to the others, so all benefit and no money is exchanged.

Everyone else has to get to the Internet by accessing one of these Tier 1 networks. The next level down, the Tier 2 networks, are also very large Internet service providers. Since they don’t have the enormous global traffic to participate in peering, they purchase what is called IP Transit. This is Internet access sold on a per Megabit per second per month basis.

Smaller Tier 3 networks can purchase IP Transit from Tier 2 networks, if they are large enough to have an assigned AS or Autonomous System number (ASN) to identify them as part of the Internet. Large scale ISPs fall into this category as well as some large corporations and other organizations.

Local and regional Internet Service Providers, including WISPs (Wireless Internet Service Providers), buy DIA or Dedicated Internet Access. DIA connections are like point to point private lines, except that one end connects to the Internet. Other private line characteristics still apply. The bandwidth provided is completely dedicated to the ISP and not shared with anyone else. There are generally SLAs or Service Level Agreements that spell out characteristics such as maximum latency, jitter and packet loss as well as time to respond to outages and time to make repairs.

Dedicated also means that there are no extra charges for heavily loading the line. You can use the entire capacity of the circuit in both directions or only some of it. The price is the same.

The smallest DIA service is usually a T1 line running at 1.5 Mbps. This is a symmetrical service, meaning 1.5 Mbps upload and 1.5 Mbps download. Usually the download path is much heavier loaded than the upload path for typical Internet access. If fact most consumer Internet access is sold with 5x to 10x higher speeds on download than upload. For business users, upload speeds can be important when transferring large files to remote backup sites and servers within colocation centers.

Obviously, T1 lines can’t serve a large user base but they work great for WiFi hotspots and rural or subdivision WISP service where signed-up customers number in the dozens, not hundreds. A nice feature of T1 lines is that they can be bonded by adding more lines to double, triple and quadruple bandwidth up to about 10 or 12 Mbps. The other nice feature of T1 lines is that they are available where other line services don’t reach. If you can get business telephone system into a facility, you can probably get T1 DIA service.

The next increment in traditional telecom bandwidth is DS3, also called T3 lines. This service runs at 45 Mbps which is large enough for a good size service provider to offer competitive bandwidth. Beyond that, SONET fiber optic services include OC3 at 155 Mbps, OC12 at 622 Mbps and OC48 at 2.5 Gbps are very popular.

A strong competitor to T-Carrier and SONET bandwidth is Carrier Ethernet. It comes in two flavors, Ethernet over Copper (EoC) typically from 1 to 50 Mbps and Ethernet over Fiber (EoF) from 10 Mbps to 10 Gbps. In a some metropolitan areas, you can also get EoFW or Ethernet over Fixed Wireless at DS3 and Fast Ethernet speeds. Where available, Carrier Ethernet tends to have considerably better pricing than other services.

Do you resell Internet access to other ISPs or end users? If so, see if you can get better wholesale pricing on Dedicated Internet Access and IP Transit services.

Wireless Internet Access For Farms

There are many advantages to living and working on a farm, but one of the disadvantages is that broadband Internet access is harder to come by. No, DSL and Cable broadband probably aren’t in your future. But there are options available at reasonable prices right now.

It’s true that DSL and Cable are popular with independent professionals, small businesses and home-based occupations. You get a decent amount of bandwidth at a reasonable cost. The one hitch is that these services are distance limited. DSL signals decrease rapidly as you get a mile to two from the telephone company central office. Cable is a wired service that goes only where the Cable company has decided that there is enough population density to justify stringing the coaxial cable. Unfortunately, those factors keep Cable and DSL within or close to the city limits.

What you really want are either line services that don’t have distance restrictions or wireless services that don’t require stringing or burying cable of any type. There are several options that meet this description.

First is T1. This is a telco digital line service first used between telephone company switching centers. The beauty of T1 is that it is designed to be provisioned on two pair of ordinary telephone wires, available just about everywhere. The second advantage is that it was designed to work with regenerator boxes that clean up and boost the signal so that it can go another mile. You can generally get T1 line service miles from the nearest town, although it gets more expensive as you get farther out in the country.

Second is satellite. Satellite broadband service comes from above and needs no wires. All it requires is AC power that can even come from a gas generator or solar panels and an inverter. Disadvantages include the need to get a professionally installed two-way satellite dish installed on your roof and a half-second or so of latency due to the long path up to the stationary satellite. For many email and Web uses, this slight delay from issuing a command to getting data back is no big deal.

A third option is wireless terrestrial Internet service. Many communities have WISPs or Wireless Internet Service Providers. These tend to be locally owned and have a very limited service area. More often than not, WISPs target rural subdivisions and small towns to get enough customers to justify the cost of the equipment and bandwidth.

One of the most exciting new services is fixed wireless or cellular broadband. This service uses the data channels that every cell phone carrier has available for mobile phones and laptop computers. Accel Networks is a leader in this field and has contracts with the major carriers (AT&T, Verizon and Sprint) to connect with their broadband data channels. By combining the coverage areas of multiple carriers, Accel can pretty much blanket the nation except for mountainous and remote areas of the West where there is no cell phone coverage. If you can get a decent cell phone signal, you can probably get fixed wireless service.

The way this works is that Accel Networks customizes their standard interface box and antenna to optimize the signal strength for your particular location. That gives you a really good chance of getting a solid signal that will deliver decent bandwidth. How much bandwidth? This service is competitive with T1 lines with a minimum rate of 750 Kbps download and 250 Kbps upload, bursting up to 1 Mbps on downloads. This is more than adequate for most farm uses, such as getting agriculture reports, using email, general Web surfing and even watching video clips. It’s not intended for high intensity usage like downloading HD movies or running a server.

What makes fixed wireless broadband service so popular in rural areas is that it is readily available and costs half the price of a T1 line or less. Is this the right service for your farm, ranch or rural business? Get pricing, availability and complete details on fixed wireless broadband now. Installation is fast, often within a matter of days.

IP Transit vs Peering vs DIA

We live in a world of networks and networks of networks. The Internet is the ultimate example of networks upon networks upon networks. All of these networks need some way to communicate. For that, you have the choice of IP transit or peering.

Network to network communication would be unnecessary if the Internet was constructed the way most people envision it. When we think of the Internet, we think of one giant network that links everyone to everyone. It generally works that way for the end user, but the notion of a monolithic universal network is an illusion. Look inside the Internet and you’ll find it to be a collection of large, medium and small networks that all work together to get packets from one point to another. Let’s see what that takes.

At the top of the heap are Tier 1 networks. These are huge international IP networks that have points of presence in key locations around the world. Tier 1 networks are indeed the superhighways of the Internet. But like all highway systems, they don’t go everywhere. In order to create an Internet, you need to connect these superhighways together.

The connection process is called peering. The name suggests that this is a connection between equals or peers. That’s exactly right. Huge networks have huge amounts of traffic. If two of these networks peer to exchange traffic on an equal basis, then each network effectively doubles its reach. Network A has access to all the customers on Network B and vice versa.

Tier 1 networks peer on a settlement free basis. In other words, the networks are interconnected via high capacity routers and the traffic flows back and forth at will. Settlement free means that there are no toll booths at the border. Neither network pays the other because they are getting equal value through peering.

Not all networks are the same size. Smaller networks, called Tier 2, have less capacity and less reach than Tier 1 networks. Tier 1 networks aren’t about to peer with Tier 2 networks at no charge because the smaller network would be getting a lot more value from the arrangement than the larger one. What Tier 2 networks can do is ban together and peer among themselves to create a much larger entity that can compete with those Tier 1 networks. If they want access to the Tier 1 networks, they can pay a settlement charge based on the traffic imbalance. That charge is called IP transit.

Internet Service Providers have a choice when it comes to accessing the Internet. They can spend the capital and maintenance cost to build out their networks to the point where they can peer with other large networks, or they can just purchase IP transit services from a large network and avoid the investment in equipment and personnel.

Very small networks or medium size companies with their own internal networks will choose to buy Dedicated Internet Access rather than IP transit. You need to be a network operator with an assigned AS or Autonomous System number (ASN) that identifies each network on the Internet in order to qualify for IP Transit services. Some large organizations with connections to multiple networks may fit this definition, as well as large scale ISPs.

Everyone else, from local WISPs (Wireless Internet Service Providers) to SMBs (Small to Medium Size Businesses) simply purchases Dedicated Internet Access by the Mbps or Gbps of bandwidth. Operation of the Internet is left to those networks who specialize in that service.

What type of Internet connectivity makes the most sense for your business? It depends on whether you are a large ISP, a content delivery network, a large corporation with international locations, or a network of retail stores. Why not compare pricing options for IP Transit, Peering, or Dedicated Internet Access, as appropriate? Complementary consulting services are available to help you sort through the possibilities.

Bonded T1 Solution Increases Bandwidth

T1 bandwidth at 1.5 Mbps has been a staple for smaller business applications. For many businesses, a solid 1.5 Mbps download and 1.5 Mbps upload is more than adequate. Some businesses can even use an Integrated T1 solution to deliver both telephone and Internet service on the same line. But other businesses are finding that T1 bandwidth is becoming a bottleneck to productivity. They need and want more bandwidth.

So, what is the easiest and most cost effective solution? A straightforward approach is to add another T1 line. This doubles your bandwidth from 1.5 Mbps to 3 Mbps. But don’t just run out and order a second T1 line just anywhere. If you want to two T1 lines to work as if they were one larger line, then you’ll need to get them from the same supplier and request a bonded T1 solution. Bonding is a technical process that combines the bandwidth of the otherwise independent T1 lines.

Why would you not want your lines bonded? One reason is redundancy. If the two lines are bonded and from the same source, chances are that a fault that takes out one line might well take out the other as well. You’ll be left with no bandwidth at all until repairs are completed. Fortunately, this is usually a matter of hours at most for top tier T1 line service providers. Even so, by keeping the lines separate and from totally different carriers coming in on different wire bundles from different directions, you stand a good chance of an outage being limited to one line or the other.

Redundant lines are easiest to implement when they feed different networks. Say, half your users are on one line and half on the other. Or, you can use a device called a TRUFFLE from Mushroom Networks to combine two or more broadband lines to create one larger bandwidth. If you lose one input to the TRUFFLE, the others keep feeding the network.

Another situation where a bonded T1 solution makes sense is delivering larger amounts of bandwidth to locations where fiber optic service isn’t available or is way too expensive to bring in. You can bond 3 T1 lines to get 4.5 Mbps, 4 T1 lines to get 6 Mbps, 5 T1 lines for 7.5 Mbps, 6 lines get you 9 Mbps, and bonding 7 T1 lines will deliver 10.5 Mbps. That’s equivalent to basic Ethernet network speeds and is more than enough for applications like video conferencing and broadband Internet access for medium size companies.

Bonding this many lines often makes a lot of sense for companies located in rural areas or just far enough from Metro Ethernet service that fiber isn’t practical. That includes WISPs (Wireless Internet Service Providers) and rural medical centers, as well as office buildings of all types. T1 line service is available just about anywhere you can get telephone service and is provisioned on the same type of twisted pair cable that brings in analog or digital phone lines.

Finally, a bonded T1 solution can provide short term connectivity while fiber optic service is under construction. In most cases, the copper wiring to support bonded T1 bandwidth is already in place. A service provider only needs to install customer premises termination equipment and provision the service. Once fiber has been brought in and turned up, you can discontinue the bonded T1 connection or keep it as a backup service that will be unaffected by faults in the fiber optic network.

Can you business benefit from a fast, reliable T1 based bandwidth service? Check prices and availability for a bonded T1 solution now. If you have an older T1 line contract, you may find that you can get more bandwidth for the same money today.

What To Do If You Hate Your Internet Service

I regularly get inquiries with comments that go something like “I can’t get any broadband” or “I hate my slow Internet access.” Unfortunately, most of these come in as requests for quotes on high bandwidth services that are totally inappropriate. So, is there any real hope for the frustrated individual or small business Internet user? You bet there is.

Broadband access is a hot potato right now. So much so that the government is spending billions to help service providers extend their coverage into small towns and rural areas where broadband is largely non-existant. This will help... eventually. But no way is there enough money available to create the kind of universal access we have with telephone service and electricity. In the real boonies, your best bet is wireless.

Before I get deeper into this, are you sure you don’t have broadband options? New build-outs are always underway and there might be something that serves your address that you don’t realize has arrived. Before you do anything else, check for broadband availability using a broadband finder service like the appropriately named “Can I Get DSL?” This free availability check will give you a list of DSL, Cable, Satellite and 3G mobile broadband services for your location.

Notice the inclusion of 3G cellular wireless. Cell towers have become so prolific that you can almost always get a signal, even out in the country where no one is stringing broadband wires. Nearly all cell towers are now transmitting both voice and data on different channels. If you have a smartphone, that’s how you get your Internet access. But you can also get a wireless modem aircard and a data-only plan so that you can put broadband on your laptop computer. Yes, it is also possible to plug one of these into a desktop computer, but beware. There is such a shortage of wireless channels that service providers impose a relatively small download cap. It’s generally either 2 GB or 5 GB depending on the service you order. Most people find this more than adequate for mobile use in checking email and browsing websites. But if you go downloading big software files or movies, you can hit that limit pretty quickly. Go over and you’ll pay overage charges that can be eye-popping.

A faster and less restrictive wireless service is 4G WiMAX, now in some 40 cities. Someday WiMAX may be the answer to rural broadband needs. But for right now, it is rather tightly deployed around major population centers. If you can get it, you’ll enjoy 3 to 6 Mbps downloads with unlimited usage. In fact, this service is advertised as being suitable for both desktop and mobile usage. The strong signals penetrate most structures, so you don’t need an outside antenna. WiMAX 4G isn’t available everywhere, but it’s worth your while to check 4G wireless availability and see if it has come to your town yet.

Another wireless option is the WISP or Wireless Internet Service Provider. These are strictly local operations set up by entrepreneurs to cover smaller towns or subdivisions located too far from the city to get wired services. You’ll have to check your phone book or newspaper ads to see if one is nearby. If so, you can get DSL or Cable speeds delivered wirelessly line-of-sight to an antenna that mounts on your roof. Some of these look like a small satellite dish tipped downward.

Speaking of satellite, two-way satellite broadband is an established technology that will work just about anywhere you can get power and a clear view of the southern sky. Satellite has gotten a bad rap because of relatively high prices, low bandwidth caps and horrible latency. The latency is due to the radio signal having to travel some 22,500 miles up to the bird and back down. It introduces a half-second or so delay into everything. For email or Web browsing, that’s probably no big deal. Just forget about real-time gaming, VoIP telephone or video conferencing. You’ll drive yourself nuts waiting for responses. Even so, for many users, satellite is a decent option. Service prices have come down recently and are similar to many DSL and Cable prices.

A lucky few also have the option to get their broadband delivered by fiber optic cable. The Verizon FiOS service offers large bandwidth and the possibility of bundling telephone and television over the same passive optical fiber.

If none of these will do the trick, you may be tempted to look into business bandwidth solutions. Don’t do it unless you can pay $300 and up per month for T1 lines running 1.5 Mbps and even more for DS3 and Ethernet. Most providers won’t even install service unless your property is zoned for business. If you do have a business location and are willing to pay what rock solid reliable business bandwidth services demand, then by all means request a business broadband service quote and see what options are available to you.

What is 4G and Why Do You Want It?

You see ads for 3G cell phones and wireless modem aircards. Now here comes 4G. What is this advance in technology all about and why should you want it now?

2G, 3G, 4G. All those G’s, what do they mean? What we’re talking about is a shorthand for the generations of wireless broadband service. It’s been advancing so fast that it’s not unusual for different generations of service to be available in the same area. That’s by design. If you are in a weak service area for 3G, then your device will automatically seek out a lower speed service such as 2.5G or 2G. You won’t get as high a bandwidth, but at least you’ll be connected.

Wireless broadband is generally a companion service to cellular telephone. It uses the same towers and base stations. Coverage areas are pretty much the same. The exception is when a particular tower site hasn’t yet been upgraded to the latest cellular broadband generation. In that case, you’ll get a lower level of service until you move into the coverage of a cell tower that is at the latest standard.

I should mention here that there are two wireless broadband services that have nothing to do with cell phones. One is the WISP or Wireless Internet Service Provider that offers home and business broadband. You need to be within line of site of their tower and install an outdoor antenna on your roof. These WISPs are pretty much locally owned an operated, and generally serve locations that aren’t wired for DSL or Cable.

The other non-cellular wireless service is the WiFi hotspot. There are so many of them, that they could almost form a cellular-like network of their own. That hasn’t happened because hotspots are also largely local services, mostly offered by restaurants and hotels. There’s no network to tie them together, so once you leave a hotspot you have to log into another one at your next stop.

That’s where 4G steps in. Imagine that you are connected to a 4G service and are reading a document while parked in your car. You can go into a client’s office or your own and you’ll still be on the same service. The idea of 4G is to blanket a city with a signal strong enough that you have high bandwidth connectivity without worrying about where you are located.

But doesn’t 3G do that? To some extent, yes. But 4G has the advantage of higher bandwidths. With the 4G service that is available today using the WiMAX standard, you can get 3 to 6 Mbps on a normal basis, with bursts of to 10 Mbps.

WiMAX 4G is also not limited to mobile service the way that 2G and 3G are. It’s designed for both desktop and mobile service. That puts this 4G network in a class by itself. You can get a WiMAX modem for your desktop computer and a plug-in 4G aircard for your laptop computer. You’ll have the same service at your desk as you do on the road. There are even 4G phones coming out sometime this summer that look to become a game changer in the wireless service industry.

There are two standards that will dominate 4G service. One is LTE which will be deployed later this year and through 2011. The other is WiMAX broadband that is available now in many cities and states. Find out if your location qualifies for 4G wireless broadband
