Electronic News reports here that - finally - we may see a cell phone with 802.11 in it, plus the software to "operate using 802.11 technology inside the enterprise and cellular telephony elsewhere". It will operate as an "extension to the Cisco CallManager IP-based communications system" so what does that mean (this is not a rhetorical question) exactly?
Apparently it means that this new device...
According to this article and this article, sales of handheld computing devices are declining about 30 percent year-over-year, and have been so doing for six consecutive quarters. Worldwide, 2.5 million PDAs shipped in 2005 Q1.
But this doesn't mean fewer PDAs are in use, does it? It could mean the market is relatively saturated and that PDAs have a longer life than PCs. Anecdotal information...
Every family of DSP chips is quite different from every other, memory architecture and pipelining is peculiar when compared to traditional microcontrollers. DSPs are generally RISC machines highly optimized for Digital Signal Processing (FFTs, image manipulation, telcom data streams, realtime video and digital audio codecs, etc). All of this conspires to make DSP one place where I thought Java...
This article in Infoworld: http://www.infoworld.com/article/05/07/20/HNmeshnetworks_1.html?source=NLC-TB2005-07-20 reports that 15 competing proposals will be whittled down to create the new IEEE 802.11s specification.
What's so great about a mesh network topology? A mesh network is a network in which the routing of messages is performed as a decentralized, cooperative process involving many peer...
This article describes a secure form of wireless sensor communication which "leverages UWB with the unyielding encryption protection of the 256-bit Advanced Encryption Standard (AES) to form UWB/AES". Among the key wireless features of the UWB/AES are its IP network compatibility and its “per-packet†rotating 256-bit encryption keys for even greater crypto-protection. The UWB/AES network...
This online article by by Mukesh Lulla, TeamF1 is a pretty good overview of the top 10 misconceptions about embedded security. It's worth mentioning here for a couple of reasons. One: embedded security is increasingly important as more embedded products are provided with a network connection to the outside world. Two: it's generally accepted that the various Java security packages are "better"...
