|Pushing fiber close to the customer is generically called “deep fiber,” and various acronyms are used to indicate just how deep the fiber is. FTTH means “fiber to the home,” which is the extreme of giving every user an optical-electrical termination. FTTC takes “fiber to the curb,” serving a group of homes, while FTTN means “fiber to the node” or “neighborhood.”

Operator studies suggest that the migratory WiMAX model is most valuable in cities with large student populations, areas where mass transit is used for commuting in preference to private automobiles, and areas where online video usage has been well-socialized among wireline broadband users.
Where there is a strong wireline content appetite, sustaining that appetite in other places where the user may relax is far easier. On the other hand, in locations where much of the population commutes by car, where the user is older and less likely to view content online at home, and where a large segment of the population of a service area may be moving in from a different area, the mobile-evolution or LTE model is easiest to validate.
|The ongoing economic downturn is fostering a changing of the guard in telecommunications services. What might look like a business depression is actually providing fertile ground for a shift in technology. It’s traditional TDM switched circuits out. IP based Ethernet connections in.

HSPA is a general name for the High-Speed Downlink Packet Access (HSDPA) and High-Speek Uplink Packet Access protocols. They are packet-based mobile telephony protocols used in 3G to increase data capacity and speed up transfer rates. One of the primary differences between HSPA and EV-DO networks is that HSPA allows mobile handsets to transmit voice and data simultaneously.
Jonathan Morgan has written a very interesting post explaining why HSPA is so important. It all comes down to dollars.
|“Beginning late 2006, major network server platform releases embraced 3Gb/s SAS and there has been no looking back.”|
Today I’m reading about SAS.
SAS is the only storage connect that embraces both the high-performance and high reliability disk drive offered with SAS connected drives, as well as providing native compatibility with low-cost per gigabyte SATA drives.
This capability allows common storage components to span a variety of storage environments, including tiered storage solutions. The ability of the storage system to scale is a critical attribute for enterprise critical data storage solutions.
|“You can’t manage what you can’t measure, and many enterprises have few or no resources devoted to measuring or monitoring how users use the information that enables and drives the business.”
Michael Dortch, Building an MDM project plan for manufacturing
Today’s WhatIs.com Word of the Day is master data management (MDM).
Whether a company uses a data discovery and mapping tool or begins by surveying users to ask them ‘manually’ about their information access and use patterns and behaviors, knowledge about current data is the first step towards truly effective MDM.
It doesn’t have to be as elaborate as a true, interconnected real-time data map, but the closer an enterprise can get to that goal as a start, the firmer the foundation of that enterprise’s MDM strategy will be.
|With D2D2T, you can transfer your data to disk at night at a much faster rate than to tape, and then migrate that data to tape, as you need to.
Phil Pascarelli, D2D2T: is it quite right for you?
Unlike tape emulation, which replaces a tape drive with a virtual hard disk equivalent, D2D2T allows users to manage the storage of data closer to an Information Lifecycle Management (ILM) model. Users can specify the destination and duration of stored data as well as its replication and archive life. In addition, D2D2T offers an excellent data recovery option, allowing instant retrieval of lost or corrupted data. D2D2T is also able to address compliance legislation-based storage requirements.
|Only 25 percent of PCs could qualify for Energy Star 5.0 compliance.
Andy Patrizio, Dell Goes Green With Energy Star 5.0 Push
The changes from Energy Star 4.0 to 5.0 are in three main areas:
– minimum power supply efficiency was raised from 80 percent to 85 percent.
– the formulation of criteria changed to get a measure of annualized kilowatt hour power usage based on typical energy consumption metrics.
– the AC power conversion rises to 87 percent efficiency.
|A patent assigned to Google describes how the search giant can monetize its Voice service: play ads while a call is dialing or placed on hold.
John Timmer, Google patent could bring ads into your phone
The patent application, called “Ringback Advertising,” is assigned to Google. In general terms, it describes a system for delivering ads to any sort of phone system, including IP, cellular, or landline phones. The idea is to place software somewhere within the flow of telephony data that can identify when a given call is not active, then request audio ads for delivery during that time. Although this obviously pairs nicely with Google’s Voice service, there’s no reason it couldn’t be rolled out to telcos that choose to partner with the search giant.
|“Mechanical Turk began life as a service that Amazon itself needed…Amazon had millions of Web pages that described individual products, but it wanted to weed out the duplicate pages.”
Jason Pontin, Artificial Intelligence, With Help From the Humans
Amazon makes money from Mechanical Turk by charging companies 10 percent of the price of a successfully completed HIT. For simple HITs that cost less than 1 cent, Amazon charges half a cent. ChaCha intends to make money the way most other search companies do: by charging advertisers for contextually relevant links and advertisements.
If you haven’t heard about ChaCha yet, it’s a free voice search service for mobile phones. It’s interesting that one of ChaCha’s investors is Bezos Expeditions, the personal investment firm of Amazon founder Jeff Bezos. According to marketing literature:
ChaCha, a free mobile answers service, allows users to call 1-800-2ChaCha™ or text questions to ChaCha (242242™) on mobile phones and receive answers within minutes. Its unique advertising solutions provide pay-for-performance opportunities for advertisers to precisely target and embed their messages within millions of text conversations.
Aha! So maybe Mechanical Turk isn’t so much about enterprise search — it’s really about mobile voice search! Makes sense. Amazon would have a revenue stream by serving highly targeted ads along with the search results.
