Xbee Wireless Kit: 802.15.4/WPAN Basics

So I decided to start with a cursory look at what these are.  From hearing folks talk about it, it seems to be some sort of wireless...something.  At first I thought it was wireless internet that you could set up, but before getting too many misconceptions about it, let's do a little research!

These actually don't seem to be too old as they were introduced as recently as 2005.  These are based on the 802.15.4 standard designed for point-to-point and point-to-multipoint communications at over-the-air baud rates of 250 kbit/s. 

The 802.15.4 standard is meant to enable the use of wireless, low-cost, low-speed communication in devices on a personal area network (PAN).

A personal area network, in turn, can be used to allow for communication between different personal devices and also to higher level networks (like the internet).

So Xbees could be considered a WPAN - wireless personal area network - where instead of requiring cables, it just uses RF.  The neat thing is that when two of them are in range of the other, they can communicate as if they were connected by a cable. (Very cool!). 

So actually, theoretically, you could make a sort of slow internet with these.  But it seems they are more used in small networks with specific data transfer functions.

Pandora's Ratings Claims: "Special Math" Under Fire

Date: 7/28/11

The latest release posted on Pandora’s investors’ website is another attempt to position Pandora as something it isn’t – a radio station. I understand their radio envy – they even refer to themselves as WPAN -- since Pandora is essentially a playlist maker set to shuffle.  But what we took away from their announcement was its failure to reach half the country, fuzzy math, and no benefit for advertisers.  So when it comes to Pandora comparing itself to broadcast radio, it just doesn’t WPAN out.

Pandora’s release centered around its having a strong presence in the top ten markets.  But if the Pandora numbers are valid, then Pandora is essentially announcing that about half or more of its total listenership is restricted to the top ten markets in the U.S. Considering the top ten markets account for only about 25% of the U.S. 18-49 population, that leads us to the conclusion that Pandora is not being embraced outside these ten markets.

On the numbers front, Pandora is making claims based on what I’ll call “Pandora’s ‘Special’ Math.”  The company hired well-respected Edison Research to create “average quarter hour” (AQH) ratings for “Pandora Corporate” (as they are listed by Triton Digital) within two age segments in 10 markets in the U.S.  We aren’t challenging Edison’s math – they’re only crunching the data Pandora gave them.  But we do wonder about all the data that seems to be missing.  Like the geographic parameters of their ratings. In order to use the only accredited ratings available, the numbers must be reported in terms of TV geographic definitions (or DMA).  If so, that would inflate their ratings when compared to the smaller Arbitron radio metro area. Therefore, they cannot be making an apples-to-apples comparison.  In addition, we’re missing a statistic that’s critical for any real radio station -- the weekly cume of their listening. As to why that was left out, we’ve pointed out before that the average Pandora listener tunes in just 2.5 times a week – clearly there’s not much of a cume to be generated by that. 

Another example of Pandora’s ‘Special’ Math:  In its initial analysts’ call, Pandora claimed that it “ended 2010 with 2.3 percent market share of all radio listening in the United States. Six months later, Pandora has increased its market share to 3.6 percent.”  But anyone who looked at the numbers would see this was a mathematical impossibility.  Triton Digital’s published ratings show a net increase of 6% in users for Pandora over that six month period.  For Pandora to equal 3.6% of all broadcast listening, broadcast radio listening would have had to drop by a third -- 32.5% -- in that same period.  But it didn’t -- In fact, broadcast radio listening remained consistent over that timeframe and, in the top ten markets Pandora targets, radio’s AQH has increased by 3.1%.  And calculations by the two actual ratings sources for radio put all digital listening at about 3% of total radio listening.  Without Pandora’s ‘Special’ Math, Pandora would account for possibly 1-1/2% of all radio listening.

As we’ve said before, Pandora is not the ideal vehicle for advertisers.  Let’s look at ad targeting – which is crucial when a buyer is considering which radio stations to include on a buy against 18-49 year olds.  Broadcast radio offers targeted environments where advertisers’ messages will have relevance and meaning.  A rating without an environment is meaningless.  Pandora doesn’t offer an environment, period, let alone a targeted one.  So, for example, if the advertisement is for a Closed Circuit Boxing match, the spot could easily be surrounded by ballads from Celine Dion.  Not what that advertiser signed up for, I bet.

Knowing radio’s place in the hearts, minds and daily lives of hundreds of millions of listeners every month, we don’t blame Pandora for wanting to be a radio station.  But as the data continues to bear out, it’s far from succeeding in making that case. 

  Respectfully,

Mary Beth

  P.S., Of course I have the data to support everything I’ve said here, and I’d be glad to share it.

WiMedia alliance announces more ultra wide band products come out with higher speed

Recently, WiMedia alliance announces the ultra wide band platforms of 4 manufacturers are authorized. Include Artimi member company that authorize ' One) , NEC group ( 2) And Tzero (one) ,Make entirely obtaining WiMedia, authorizing wireless numbering of platform, reaching 23, this, in order to hope to integrate ODM and OEM manufacturer based on WiMedia wireless USB product of future generation to offer more choices. In-Stat chief analyst claims: " the apparatuses of ultra wide band and wireless USB have already entered the market at present, more WiMedia authorizes the wireless products (WiMedia CWPs) Will lead the market to advance through the solution of interconnection and interflow. Different platforms between a plurality of chip manufacturers are offered the wireless solution of intercommunication, support PC and multimedia application, it is convenient to use equally with having collinear USB, are promoting acceptance and application of the market.

It is that a series of alliance authorizes the key in the plan, canonial conformance of WiMedia ultra wide band of mainly lying in guaranteeing and world that the platform is authorized. CWPs tests the physical layer (PHY) strictly And media accessing control layer (MAC) ,Guarantee the apparatus based on WiMedia CWPses of manufacturers can offer high quality, high performance and service used conveniently. The kinetic energy of market of the ultra wide band continues increasing. WiMedia CWPs available quantity has already been turned over time than October of 2007. In addition, increasingly many apparatus manufacturers such as Belkin, D-Link, Dell, IOGEAR, Lenovo, NEC and Toshiba have appeared too on the market. Market survey shows such a producer will continue increasing with the appearance of increasingly many CWPs.

The Vice President Tom Siep of WiMedia alliance shows: "WiMedia CWPs has left a foundation of wireless multimedia products on the future generation, the application appearing at first will be wireless USB. Increasingly many CWPs makes the market of wireless USB in the fast development. We are very glad to see our member company authorize the platform in the world, support the technical use of the ultra wide band. " It if you can't devoted to at high density in environment, offer it language human relations than speed transmit, WiMedia ultra wide band leading Wireless Personal Network (WPAN) Multimedia application technology. 4 CWPses that announce this time continue being based on norm of WiMedia ultra wide band, has the ability to offer the transmission rate of signal higher than 480Mbps.
