Wireless Tips: Roaming to the Wrong AP
.
.
When you connect to a wireless network, you are connecting to a single access point (AP) -- though the radio card (aka client card, network interface card, or NIC) in your laptop will roam to other APs with the same SSID (or network name), which allows mobile users to move about a facility and continue to use the network. However, not all client radios use the exact same reasoning and techniques to deal with roaming, and radio frequency (RF) interference and other environment conditions can cause problems.
.
If your wireless network is outfitted with multiple APs, and users experience poor signal strength and performance despite proper coverage in the area, the user’s radio card may not be connecting to the closest or most ideal access point for that specific location.

T6 Commentary: A Common problem for wireless connections with remedies which carry no guarantees; physics, she is a demanding mistress. Understanding signal propagation, possible interference sources and just how RF coverage areas work is essential to providing assured connectivity. Complete coverage does not necessarily translate into overlapping polar patterns that could cause more issues then they solve. I did start off with this article quote under the “Working Knowledge” section but considering how often I answer this type of question I find it appropriate to start off with this bit of advice.

FCC Cites Two For DTV Tuner Violations
.
.
The Federal Communications Commission Tuesday issued “apparent liability for forfeiture” notices to flat-panel TV manufacturers Regent USA (Maxent) and Syntax-Brillian (Olevia) for allegedly failing to comply with its ATSC tuner mandate.
.
The FCC said the rules were “intended to facilitate the transition to digital television by promoting the availability of DTV reception equipment and to protect consumers by ensuring that their television receivers will provide off the-air television reception of digital signals just as they have provided off-the-air television reception of analog signals

T6 Commentary: With the Analog cutoff deadline fast approaching and major manufactures hyping the heck out of HD, one has to wonder just why someone would do this. The FCC has made it quite clear –(Janet Jackson-esq acts are verboten serious)- that it would not tolerate such violations. I find no reference from any sources that the manufacturers made any false claims; they simply sold NTSC analog receiving sets. This raised the ire of the FCC but nary a blink from the general buying public, who seem blissfully unaware of the impending change over. HD awareness and acceptance is still an elitist’s fascination, so far as acceptance into the home. The regular patrons to most sports bars well know which places have HD with the biggest screens. To be fair most inhabitants of major urban area who receive the majority of TV signals via cable will not notice much of anything, even if they have not updated their video monitors|tuners. My take on this is that most manufacturers have taken note of the publics’ blasé response to the warning flags and are willing to make a few extra bucks on selling soon to be ‘obsolete’ receivers, knowing that the majority will never know the difference.

Dell reportedly to exit LCD TV market
.
.
Dell, the world's No. 2 personal computer maker, will cease making Dell-branded LCD TVs this month, the Chinese-language Economic Daily reported, citing unnamed sources.
A Dell representative said the company currently sells LCD TVs in a limited number of markets, including Japan and the United States, but had no comment about the Economic Daily report.
..http://news.com.com/Dell+reportedly+to+exit+LCD+TV+market/2100-1041_3-6189309.html?tag=nefd.top
..T6 Commentary: The falling margins specter claims yet another vendor, combine the above with announcements from major Plasma and LCD manufacturers of planned production partnerships, and you see the last halcyon days ending. Pundits from economic publications such as the Wall Street Journal and Motley Fool see this as a ‘natural consolidation’ as market saturation becomes complete. From my observation point it looks more like the event horizon of a Black Hole, singularity being the remnants with only one real producer of panels. You may have many names slapped on the front but it will all be ‘X’ on the inside. In an unfortunate mix of metaphors I am reminded of the line in ‘Demolition Man’, where the Sandra Bullock character explains that, after the “ Franchise Wars” all restaurants are Taco Bell.

Converters Signal a New Era for TVs
.. At midnight on Feb. 17, 2009, the rabbit ears and the rooftop antennas that still guide television signals into nearly 1 of every 5 American homes will be rendered useless — unless they are tethered to a new device, including two versions unveiled yesterday, that the government will spend as much as $80 a household to help families buy.
..http://www.nytimes.com/2007/06/07/technology/07digital.html?ref=technology&pagewanted=print
..T6 Commentary: In both contrast and support to my above commentary, the quoted article here states that the analog cut off may strand nearly 20 million TV viewers who still receive signal via antenna. In an attempt to head off the cry of angered constituents and –more importantly, preserve the Nielsen based ad revenue of broadcasters- congress has been hashing out legislation to provide vouchers toward the purchase of converters. Various bills have made their way in and out of approval committees in both houses, with much hand ringing, standards verification, monies to allot and protection of profit for the manufactures of the aforementioned converters.
For more background on the congressional debate see T6 issue Volume 1, Issue 9 and the article quoted ‘Lawmakers split on subsidy for digital TV converters’; the original link is at http://www.usatoday.com/money/media/2005-05-26-digital-usat_x.htm (notice the original posting date, yeah it has been going on that long).
For an interesting article on how the analog cut off will be affecting many more rural viewers, See T6 Issue 9 Volume 3 for more details on congressional voucher debate.

FCC Clarifies Cable Wiring Rules For MDUs
. . The Federal Communications Commission (FCC) Thursday approved measures to encourage more open competition for telephone and video services in apartment, co-op and condominium developments, by addressing access rights to installed wiring. . Under the measure, new entrants seeking to compete for service against an incumbent video or telephone service provider will not be required to cut through walls to connect new cable lines inside the unit, and will be able to use cable lines and sub-loops installed by incumbent service providers |
.
.
http://twice.com/article/CA6448168.html
.
.
T6 Commentary: The ruling is not surprising given the FCC’s past rulings allowing competitors have fair and equal access to pre-existing phone lines, built and maintained by another. The ruling insures that a provider cannot require it’ own branded equipment as the only interface to the access lines. The ruling does not restrict what a condo or Co-op board can decree as the standard and must buy for the building, but it does allow a Condo | Co-op board the power and flexibility to get the right mix of features and cost. For the contracted straight installer any transition is transparent. For the designer, sales force it gives not only a wider choice of products to offer the end client, it gets them in the game to start. I have not read through the entire ruling – it will put you to sleep, trust me it has twice – but I suspect the standard lease fees will apply so the backbone supplier does not lose out or just opt out of new builds.

Mike Volpi's trek from Cisco to Joost |
.
.
Since this is all professionally produced content, how will you deal with the whole pirating and digital rights management issues?
Volpi: First, the only content that gets on Joost is from an authorized content owner. And once the content is injected into the system, it's encrypted. Authorized users can then watch it on their computers, but they can't copy it or record it. So even though it's a peer-to-peer service they can't upload or rip the video. And the
.
So people have to watch advertisements throughout the streaming video clip?
Volpi: Yes, they'll sit through periodic ads, but it's free. And the great thing about Joost for advertisers is that we know exactly where our viewers are because they are all connecting using an IP (Internet Protocol) address. We also know what they've watched in the past and for how long. So advertisers can do precise, tailored advertising to a particular individual rather than blasting the same commercial to millions of TV viewers. So if you and someone else were watching the same thing on your laptops sitting right next to each other, it's very likely that you will each see different ads

It is of note where Mr. Volpi was before joost, do not think for a moment that both sides are unaware of the strategic value of this.

‘Apple TV Not Priced for Profit, Study Says
.
.
Without big profits on the line, what's Apple's motivation to sell the Apple TV? iSuppli suspects that it's to migrate content purchased through the iTunes Store to the living room. What's more, Apple's taking a crack at a market that other companies haven't been able to penetrate with any sure success: bringing Internet content -- such as YouTube video -- to the TV.
The company predicts Apple will sell 1 million Apple TV units in 2007, with 1.4 million moving in 2008. That's well above the few hundred thousand others have shipped, according to iSuppli vice president Mark Kirstein. No one, he said, has found the "secret sauce" to sell more than that

T6 Commentary: Apple has tried numerous times to sell a TV | computer married product with rather abysmal results. I feel apple is looking for the mass integration of the Apple TV product in the same was as the iPod has saturated the consumer markets, winding up in all manner of products from control \ audio distribution systems to factory installed in cars such as GM and BMW. Could the folks at apple be looking to replace the back seat DVD players; or the in-seat Media distribution systems in planes such as Jet Blue, Cathy Pacific and others? Does Joost have them beat on this with the Streaming (no download) method?

‘Wake Up and Smell the Network
.

a technology called Wake on LAN can let you bring your PC back to life no matter what power-saving mode it's in — even if it's completely turned off. In order to take advantage of Wake-on-LAN, your system's BIOS, Ethernet adapter and network drivers must all support the feature, but as long as your system is less than about five years old, it should be compatible.

T6 Commentary: Saturday was the 92 birthday for Les Paul. If you do not know who Les Paul is then shame on you, for he –with his wife, the fascinating Mary Ford, practically invented Multi-Track recording. For those of us old enough, it is a sad state to think many of the up and coming musicians and recording engineers do not know Les Paul’s music or contribution to the recording arts.
.
‘
“ In addition to his work on the solid-body electric guitar, Les Paul also marketed the first eight-track tape recorder in 1952 with the aid of Ampeg and has contributed greatly to the field of recording. He is credited with the pioneering uses of close miking, echo delay, and overdubbing” (source:
http://wi.essortment.com/lespaulmusicia_ricz.htm)
.
.
There are a number of great articles on Les Paul who still plays live nearly every Monday night at the Iridium in NYC. (Stop and take that last fact in, Les Paul, 92, still plays a 1 hour to 2 hour set every Monday night AND tours regularly – You and I should be so lucky).

If you find Les Paul interesting, you should look into the life and works for Rudy Van Gelder a good start would be http://en.wikipedia.org/wiki/Rudy_Van_Gelder. Go listen to the original recordings of Coltrane’s Black Pearls (recorded in live in 1958 on a 3 track ‘bandsaw’ tape deck), it blows away any thing that has come since.
