4GWE: Development Tools

September 2, 2009


Development Tools for 4G Hardware and Software, Part 1
(4G4-01)
Wednesday - 09/02/09,  8:30-9:45am
The mathematical theory often associated with wireless and mobile physical layer algroithms are complex and require a lot of thought when looking for new solutions in the wireless network. OFDM and MIMO are at the base of these algorithms. These sessions provides an intuitive and straightforward view beneficial to a wide audience of engineers and project managers.


After an overview of the discussion about how to design a 4G device from Frank Schirrmeister of Synopsys, Frank Vincze of Steepest Ascent talked about the library software.

The Library from Steepest Ascent deals with issues of channel optimisation, MIMO, and other LTE device management charteristics.

Operations that are needed to manage the development of the device in a set of libraries that take you through the OSI stack. 

Frequency Division Duplexing and the transciever functions are all within the library. 

The library has prebuilt models that represent some standard models of design.  This allows product differentiation to be done in relation to some standard sets that include test scenarios.  All of this done within the Math Kernel Library within System Studio.

Frequency is the subcarrier which makes up the orthogonal portion of the  OFDM strategy.

LTE uses a number of channel coding techniques in LTE.

The channel that makes the bitstream is controlled with a blended data channel and the control channel. 

All this signal processing equates to the throughput of the device. 

The algorithm in the MLK are put into the parameter blocks represented in software to enable the developer to manage the design through a GUI tool.

In LTE there are a number of reserved spaces in the packet format of the signal.

The blocks are the Scrambler, Symbol Modulation,  Layer Mapper and Precoder.  After your precode is completed it gets added to the LTE reserved signalling formats.

By using the libraries you get the benefit of testing against real data.






























Voice on 4G? Inevitable... But Not Anytime Soon

September 1, 2009

With back to back sessions this afternoon at the 4GWE Conference, it's tough to cram all this great info into short blog posts (but of course that won't stop us from trying). In a panel this afternoon about Giving Voice to 4G, the bottom line seemed to be that given the advanced characteristics of 4G delivery technologies (mainly LTE, but WiMAX too), it shouldn't be a problem to eventually add voice to a 4G wireless service. The harder part? Trying to decide which technological path to take, and how to mix voice in without killing off existing 2G and 3G services, which rely on voice margins for profit.

Mehmet Balos, CTO of Genband, did a good job of explaining the different methods being considered for Voice over 4G -- basically either a 2G-compatible direction, a method called VoLGA, or a full-blown IMS.

Mobile Social Applications: How Carriers Can Help the Conversation

September 1, 2009

The panel here at 4GWE on Mobile Social Applications picked up a theme from Brough Turner's earlier presentation -- that there is a big potential audience for applications that make use of mobile data owned by the provider, such as a user's location, their status, etc., especially when linked in a sharing fashion, such as on Facebook or Twitter.

Troy Cross, head of sales at voice-recognition supplier Vlingo, said that mobile access to social networking applications "allows you to connect to your friends faster," a "significant behaviorial change" as opposed to updating Facebook only when you are sitting behind a PC or laptop.

Shoshana Loeb, executive director and chief scientist at Telcordia, said there will be personal tradeoffs that will determine how successful mobile social media devices and applications will be -- such as cost for perceived value, and whether or not people feel comfortable allowing personal data like location to be shared.

"The technology allows you to lose your privacy much more easily" than in the past, Loeb said, guessing that governments everywhere will soon look more closely at the privacy concerns of mobile customers. Vlingo's Cross also predicted a "tsnuami" of regulation related to use of mobile data while driving, as consumers go on beyond simple "texting while driving" to trying to update a Facebook page while behind the wheel.

Nokia's Timothy Jasionowski opined that the industry now is at the state of "throwing rocks at each other," but that widespread availability of GPS-enabled phones has "opened up a giant laboratory" for experimentation. One unanswered question from the audience: How can corporations make use of mobile social networking technologies? Ideas?







Brough Turner: App Developers Will Lead Mobile Innovation

September 1, 2009

If there was one key takeaway from Brough Turner's excellent kickoff presentation Tuesday at the 4GWE conference it was that application developers, and not the carriers themselves, will lead the way when it comes to the next opportunities for the mobile Web.

"The initiative has passed to application developers, and that's something the [service] providers now concede," said Turner, at the end of a far-reaching look back at the development of mobile data usage, and where the future lies.

Some key trends for the future as identified by Turner:

-- Apple's iPhone and its app store are the wave of the future everyone else will copy. "It's just an easier method of discovery and distribution," said Turner.

-- More and more smartphones will ship from multiple providers. "The iPhone has shown what is possible, and everyone's scrambling to provide a similar rich browsing experience," Turner said.

-- There won't be a PC-like consolidation of the mobile platform market anytime soon, due to the wide choice of devices, operating systems and presentation methods -- none of which has established a Windows-like superiority over any other. Turner said that at least three to five mobile formats -- iPhone, Android, BlackBerry, Nokia and perhaps one more -- should remain relevant enough for the near future to continue to attract developer attention.









Does your 4G Device Communicate of Compute?

Does your 4G Device Communicate or Compute?
(4G2-02)
Tuesday - 09/01/09,  10:30-11:45am
Cell phones provide texting, email, browsing and picture taking capabilities. Many consumers think of their phone as a computer while the computer manufacturers see computing opportunities for mobile internet devices. What leading applications will drive manufacturers to build a cell phone that computes or a computer to communicate? In a 4G world, how many devices is the consumer willing to own?

Mobile Internet Devices will enable exciting new applications for the broadband consumer. How will smartphones and netbooks change the way we work and play. What are the major differences between these two categories of devices and will they eventually blend into one type of device? What unique services will MID's provide access to?



Skype Sale has 4GWE Buzzing

September 1, 2009

Talk about a wake-up call -- as folks file in for today's 4G Wireless Evolution conference here in Los Angeles, everyone is talking about the sale of Skype to some Silicon Valley private investors at a valuation of $2.75 billion.

Though the news of the deal was first reported last week by TechCrunch, we like our old pal Om's take on why eBay shareholders shouldn't feel so good about the deal. For VoIP veterans on hand here in Los Angeles, the deal brings back memories of the 2005 VON Fall show in Boston, when the first "Skype Sale" deal put a big number on the enthusiasm behind Internet voice. What does the current deal tell us about the state of the industry in 2009? That is one topic we are sure to hear more about this week at 4GWE and IT Expo.

Towerstream Delivers 4G to 4GWE

September 1, 2009

I am sitting at the Staples Convention center on a 22 MB pipe reaching out to the world at a speed I can't replicate at my home, in the car, in the office.

The reason is that Towerstream delivered a WiMAX service to the 4GWE for us to show what is available today.

We have closed the network but our participants will be able to zoom out on the net.

Zoom Zoom is not only for Nissan.

Thats a lot of Stimulus

August 27, 2009

Over 2,200 Applications
Over 25 B Requested (4 B has been Allocated)

WASHINGTON- The Commerce Department's National Telecommunications
and Information Administration (NTIA) and the Department of Agriculture's
Rural Utilities Service (RUS) announced today that they received almost 2,200
applications requesting nearly $28 billion in funding for proposed broadband
projects reaching all 50 U.S. states and territories and the District of Columbia.
This is the first round of American Recovery and Reinvestment Act funding
aimed at expanding broadband access and adoption to help bridge the
technological divide and create jobs building Internet infrastructure, with $4
billion available through loans, grants, and loan/grant combinations. 
 
The Recovery Act provided a total of $7.2 billion to NTIA and RUS to expand
access to and adoption of broadband services. Of that funding, NTIA will utilize
$4.7 billion to deploy broadband infrastructure in unserved and underserved areas
in the United States, expand public computer center capacity, and encourage
sustainable adoption of broadband service.
