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.

The future of computing is in the cloud...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.

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?

4G wireless broadband2G, 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

3G 4G Mobile Bandwidth

The Internet long escaped the desktop and moved onto the mobile phone. The problem is that it has been following a similar learning curve that took us from 300 baud telephone modems to DSL & Cable broadband and now to high speed wireless and fiber optic service. Mobile bandwidth is undergoing a steady evolution, with the demand for higher and higher speeds pushing the technology. Let’s have a look at what’s available and what’s coming soon.

3G and 4G Mobile Bandwidth OptionsThe benchmark today is 3G wireless. This service offers somewhere between 500 Kbps and 1.5 Mbps and is owned and operated by the cellular carriers. The same company that sells you your cell phone minutes also sells you 3G wireless Internet access. The signals come from the same towers, so if you are in a dead spot for phone reception you won’t be surfing the Web or watching videos either.

The 3G build-out has been proceeding at something of a panic level, especially since the introduction of the Apple iPhone. The first iPhone used the AT&T EDGE network, which is actually called a 2.5G network. That means it has considerably less bandwidth than the newer HSPA or High Speed Packet Access 3G network, perhaps as little as a tenth as much. HSPA is offered by GSM carriers AT&T and T-Mobile and is also known as HSUPA.

A competing 3G service is offered by CDMA carriers Verizon and Sprint using a different technology. Theirs is known as EV-DO and EV-DO Rev A. Download bandwidths are in the range of 1 to 2 Mbps, depending on signal conditions.

Note that 2.5G and 3G cellular broadband not only gives cell phones the ability to download videos and surf the Web but also gives you the option of adding 3G to your laptop computer. The functionality is added using a plug-in wireless modem aircard. These are sold with data-only service plans, since they don’t work as telephones. The aircard and wireless service has been a boon to field sales people who don’t always have the ability to set up shop within a WiFi hotspot.

The newest service on the market is called 4G mobile bandwidth. Right now the run away leader is the WiMAX service offered by Clearwire and Sprint under the CLEAR trademark. WiMAX is yet another wireless standard, albeit a global one not associated with the cellular phone system. WiMAX offers a powerful signal that covers an entire city. It’s strong enough to penetrate buildings so that you can have the same WiMAX broadband on your desktop and laptop computers. Download bandwidth typically ranges between 3 and 6 Mbps, considerably faster than 3G networks.

The cellular companies aren’t sitting still, though. Both AT&T and Verizon plan to deploy another standard called LTE to compete with WiMAX. It will likely be a year or two before these two 4G technologies are competing head to head in most populated areas. For now, WiMAX gives you the most mobile bandwidth at the lowest cost in the cities and states where it is available.
