Can LTE Replace Fixed Wireless?

AT&T says it will invest $14 billion over three years in new broadband facilities, including $8 billion for mobile and $6 billion for fixed network initiatives. The program would bring "fiber to the node" services to 75 percent of AT&T customer locations. 

Perhaps significantly, AT&T says the investments will provide Long Term Evolution high speed access to 99 percent of AT&T's customer locations. 

In other words, one might argue that nearly a quarter of AT&T customers might find that faster broadband access is made possible by LTE mobile networks. 

Some now argue that LTE can replace T1 service. Others argue that cable modem service can cannibalize both T1 and DS3 or other high-capacity access services. That might be more true for business customers than consumers, given the higher price-per-bit of LTE access, compared to either telco DSL, fiber to the node, fiber to the home or cable modem high speed access. 


In some ways, that is a simple continuation of global trends we have seen since the mid-1990s, when mobile began to represent a greater share of industry revenue. 

In 2016, IDATE predicts that the number of LTE subscribers will exceed 900 million, compared to nearly 230 million for fixed ultrafast-broadband using fiber to the home, fiber to the building or high speed digital subscriber line (VDSL).

One Way of Looking at "Small Cells"

Even a casual conversation about the definition of a "small cell" will quickly lead to a series of necessary qualifications and a "fuzzy" answer. Pressed for a concise answer, many observers might point out that a "small cell" approach meaningfully could include every radio installation
smaller than a traditional cellular macrocell.

And that's quite a lot of terrain. It includes "carrier" cell sites of 2-kilometer radius, "pico" cells of  perhaps 200 meters, but also customer-owned "femto" cells that cover indoor areas of perhaps 50 meters, and use the customer's own "backhaul" or "access," not a carrier-supplied link. 

Those are some reasons why the "heterogeneous network" terminology now has become commonplace.  Future mobile networks will use a variety of cell types, with different capital investment parameters and coverage areas.

Future networks also might make much more direct use of both carrier-supplied and customer-supplied backhaul. A carrier public Wi-Fi hotspot might use a carrier-supplied access connection, while, on an informal basis, most smart phone customers use their own fixed network connections, with their devices connected to in-home or in-building Wi-Fi, in place of any of the mobile cell site types. 

Without making too much of the development, "heterogeneous" implies a mix of carrier and consumer-supplied radio and backhaul network resources; a range of management options and quality of service mechanisms. 

One might also say that heterogenous networks and customer offloading to Wi-Fi also represent an unparalleled and new form of asset sharing. Whether by formal contract or simply informal mechanisms, customers are using a mix of carrier and "owned" access to support their "untethered" access requirements. 

While some entrepreneurs continue to work at creating whole networks using end user supplied access and radio assets, the heterogeneous network does the same thing, essentially. In a broad sense, users and their devices are supported by a mix of carrier-owned and customer-owned networks, both "mobile" and "fixed," using mobile air interfaces and simple Wi-Fi. 

The point is that "small cells" are more than a technology. They are part of a shift to more use of "shared" networks in a real sense. 

Smart Phones Now Lead Public Wi-Fi Hotspot Activity

Smart phones now are the devices most often used at Wi-Fi hotspots, a study of Wi-Fi usage now finds. Respondents said 40 percent of Wi-Fi hotspot connections were used by smart phones, while 39 percent were notebook PCs. Tablets represent 17 percent of connections. 

As you would guess, Wi-Fi is said to be playing an increasingly important role as a feature of a mobile or fixed network high speed Internet access service. That, in fact, is why cable operators and telcos have moved to offer public hotspot networks in their service territories, for example. 

Smartphones overtake laptops as the most popular way to connect to Wi-Fi Hotspots

Telefonica to Compete with Amazon for Cloud Computing Infrastructure

"Instant Servers" is a cloud-based infrastructure as a service offering that Telefonica hopes will allow it to offer a big branded alternative to other services such as Amazon's Elastic Compute Cloud that offer virtual server services.

That a big global telco thinks cloud computing is a business opportunity is not new. But the move might also illustrate one other aspect of competing with Amazon. A big company, with a "trusted" brand might be helpful, and sometimes essential, for any would-be competitor to firms such as Amazon. 

Some familiar with customer opinion surveys might counter that people do not "like" their telco suppliers so well. That is true. But the issue is "trust," not "likability." The point is that potential customers might trust a telco to engineer and operate a reliable, available service, even if those suppliers are not particularly well liked. 

Instant Servers promises 99.996 percent availability with a service guarantee that pays customers when those service level agreements are violated. 

Telefonica  also says its clouds can quadruple in capacity instantly, and without rebooting.

Will Mobile UC Mostly be a "Consumer Tools" Development

Mobile unified communications is in the early stages of mainstream adoption, so it is tough to predict how it will develop. But there is at least some thinking that consumer tools, not enterprise solutions will be a big factor.

In fact, some question the findings, arguing that survey findings might be overstating the use of "enterprise" unified communications systems and tools.

The native capabilities on virtually any smartphone can provide click-to-call, click-to-join a meeting, access to multiple communications modes (text, email, voice, or video), and a number of other features that either by themselves or through the use of a network-based service like Skype could be called "UC." 

The longer term issue is whether consumer tools might wind up representing a huge part of business mobile UC adoption. 

1000-Fold Improvement in Mobile Bandwidth Requires Multiple Changes

Though some might question the assumptions, many in the mobile industry would argue that a 1,000-fold increase in mobile bandwidth is going to be needed, over time, and some think that will be necessary as early as 2020.

That assumption tends to rely on typical mobile consumers downloading a gigabyte every day. You can make your own assumptions about whether that is a reasonable assumption. 

No single technique is likely to provide an improvement of three orders of magnitude in mobile bandwidth, though. So most think several different approaches will be needed, in tandem. 

One promising example is the “Neighborhood Small cells” model — a network of extremely low-cost, plug-and-play, open, indoor small cells, Qualcomm argues.

What makes the approach unusual is that the subscriber hosting the cell supplies the backhaul, which also bleeds out into the neighborhood to reinforce mobile coverage for other neighbors.

Studies show potential capacity increases of up to 500 times with a mere nine percent penetration of households and up to 1,000 times with 20 percent penetration, when combined with 10 times more spectrum.

Qualcomm is among firms that see three basic ways to get to a 1,000-fold increase in effective bandwidth. Virtually all the ways to get to 1,000 involve more spectrum, more small cells and use of offload strategies or better coding techniques.

Is 1-Gbps a "Hail Mary Pass"for Burlington Telecom?

Financially troubled Burlington Telecom, a municipally-owned communications provider, has decided to sell 1-Gbps Internet access services. 

The symmetrical 1-Gbps service will sell for $150 to $200 a month. The issue at this point is whether the new superfast access is capable of turning around revenue enough to stave off a financial collapse. 

A 2010 study concluded that “BT is not viable in relationship to its current debt load of $51 million and its ability to generate earnings to repay this debt."

"BT cannot meet its principal and interest obligations at this time,” the study concluded, noting that the company’s current business plan can’t meet future financial challenges either.

An agreement with pirmary lender Citibank in March 2012 stipulates that the first 60 percent of BT profits are to be paid to Citibank, which means taxpayers now are second in line to protect their investment. 

At current rates, it will take 96 years for BT to pay off the Citibank loan.
