SDK Release 1.1.5


Today is the release of the 1.1.5 SDK, which, as always, is available for download on our Google hosting project. The release notes contain all of the nitty gritty details. Here's a summary:



For this release, we've added these features:



The SDK also contains the following issue fixes:



It's also worth noting we released the 1.1.4 SDK on Friday, September 26, fixing two Windows SDK bugs: one issue with escaping in the app.yaml file, and another fixing issues with the datastore viewer on the SDK.



We'd love to hear your feedback on the Google group!

WiMAX World: Redline chooses picoChip SDR Platform

Getting an early jump on the news coming out of WiMAX World conference in Chicago occurring September 29 through October 3rd, picoChip on Monday announced that Redline Communications, a leading provider of standards-based WiMAX access and broadband wireless infrastructure products, has selected their PC8532 modem to power its next generation RedMAX 4C� Mobile WiMAX basestations. picoChip is a leading supplier of high-performance multi-core DSP, offering a powerful platform to develop products for emerging global wireless communications markets such as WiMAX, WCDMA, LTE, TD-SCDMA and 4G. picoChip�s products scale from femtocell access points and picocells to sophisticated multi-sector carrier macrocells.

The agreement gives Redline access to a software defined radio (SDR) platform with best-in-class performance/cost ratio. Redline has added its low-complexity maximum-likelihood receiver to the picoChip design in order to increase uplink system performance for coverage and capacity. The software-defined system supports upgrades to future standards, such as LTE, 802.16e Release 1.5 and 802.16m.
Redline, which is also an exhibitor here at the show, sells to carrier and enterprise level organizations in both developed and key high-growth markets around the world, and has more than 166 deployments of its WiMAX Forum Certified� systems to date. The company has previously delivered mobile broadband to UK and Silicon Valley train networks and created North America�s largest education sector wireless network.
Speaking about the agreement, picoChip�s CEO and president, Guillaume d�Eyssautier, stated: �Our ability to offer advanced IO-MIMO capability and future support for 16m and LTE helped, but the fact that they (Redline) were persuaded by the quality our PHY is testament to the strength of the picoChip offering. We are very excited to have Redline as a key customer.�
The Redline RedMAX 4C Mobile WiMAX platform, which is based on the WiMAX industry�s 802.16e-2005 standards for mobile WiMAX, supports a wide range of fixed, portable and mobile wireless services including support voice and video over IP, broadband Internet access used to support high value education, medical, transportation and municipal applications, VPNs (virtual private networks) and other advanced communications services.
The RedMAX 4C is designed to enable operators to maximize the reach and customer density required for a profitable carrier business model. It includes a modular, standardized �TCA (micro Telecommunications Computing Architecture) chassis basestation that is small, lightweight and easy to deploy. RedMAX 4C will also include a suite of indoor and outdoor fixed and portable end-user devices including laptops, mobile handsets and PDAs. Redline�s new WiMAX offering is also designed to facilitate the integration of its existing RedMAX products with its RedMAX 4C technologies, providing operators a path to true mobility.

Emdrive - Microwaves to Create Space Thruster?



Something a little more from fringe science: I recently heard on my favorite tech news podcast that there was an article published in New Scientist about a space (as in outer space) drive that converts electrical energy into thrust using microwaves. It has caused a lot of uproar about not being possible because it violates the law of conservation of momentum, making it impossible to build. But the Chinese (looking for any technological advantage in space they can get) claim to have confirmed the theory and are building a demonstration unit.

The theory is that the drive creates thrust by tapering a resonant cavity filled with microwaves. The thrust is small, 85 compared to 92 mN for the NSTAR ion thruster used by NASA, but enough to power space vehicles and it uses much less power than the NSTAR. Apparently, the microwaves are introduced into a tapered cavity and strike the larger end of the cavity with more force than the smaller end that has less area which creates thrust. One big question is why doesn't the force exerted on the sides also create opposing forces that cancel out each other.

Interesting stuff - we will have to see how it works out. Some of us might be building space thrusters soon. Do you think it will work?
