ATT labs on Integration of Wireless LAN and Cellular

A paper on IEEE Internet Computing Magazine Internet Roaming introduced a solution to the underlying problem. It combines WLAN security and seamless roaming, again, using Mobile IP.

HP Mobile Printing: Automatic Service Discovery

Just took a note on HP Mobile Printing. It looks like a scheme of automatic service discovery in mobile environment. Need to read more ....

Seamless Roaming between WLAN and Cellular

Just found a link here that lists papers in the area of wlan & cellular coexistence. The INFOCOM03 paper from Bell Labs is the latest one, worth reading.

Linux headed for worldwide smartphone domination

Linuxdevices.com has a story :Linux headed for worldwide smartphone domination about OS battlefileds of smart phones. According to a report from Zelos Group, Linux will beat Symbian and Micrsofot Windows Mobile (where is Palm?).

Bell Labs Mobile Location Software

Bell Labs network engine lets cell users decide how to share location information, which is being presented at the 2004 IEEE International Conference on Mobile Data Management in Berkeley, Calif. The paper is "Enabling Context-Aware and Privacy-Conscious User Data Sharing"
Richard Hull, Bharat Kumar, Daniel Lieuwen, Peter F. Patel-Schneider, Arnaud Sahuguet, Sriram Varadarajan, Avinash Vyas (Bell Labs, Lucent Technologies, USA).

I am particularly interested with how accurate the location service is, and for different business groups how to take advantage of this to "help(Spam (?)" cell phone users.

btw, the MDM04 conference seems to have a couple of good papers and projects. Check it out dude.

AAA cross-operator testbed

A paper from Inter labs (link talks about building a testbed for an AAA framework. Print it first.

Intel Labs's Communication group

Just found some interesting papers at Networking and Communications - Research and Development at Intel. The universal communicator looks pretty amazing.

Connecting to Multiple Wireless LANs with One Card

The research report discussed the way to 'virtualize' a wireless LAN card to support multiple wireless LANs(may be in infrastructure mode or ad hoc mode). An intermediate layer is added between IP and device driver to switch the card periodically among available wireless LANs, basically a time division approach on MAc layer. An adaptive algorithm is developed to favor wireless LANs of better performance. Soft turn-on and off can be done in device driver. Each virtual lan card has an address.

This is basically something about supporting infrastructure mode and ad hoc mode at the same time. Can this be done to support cellular and WiFI at the same time? Who is doing this?

Home Stereos working with Home WiFi

NetGear's new digital music player device allows to play mp3 and windows media audio files stored in a PC with your home stereos wirelessly. You don't need to have a sound card to line-out. A remote control will help you navigate the LCD on the device to select files.

Yet another example of integration of home electronics with home networks.

High Definition Radio, and Satellite, and Meteor Burst Communications

HD radio technology from iBiquity Digital seems to be the most recent public wireless radio service, along with satellite digital radio from Sirium and XM. Just because audio quality has been upgraded to digital does not mean this technology will take off a bit - Who cares the quality of an FM radio while driving or working at office?

Speaking of Satellite Wireless, here is a list of existing apps I can come up with:
1) Orbiting Satellite Wireless Phone, i.e., LEO, MEO, and GEO. LEO is the trend, although Iridium, the largest and best-known LEO system was forced into bankrupt in 2000.

2) Satellite Radio, anywhere, anytime, digital

3) GPS, and other special purpose satellite such as meteorological satellite, military-use satellite, etc.

4) Satellite Data Service

Recently there has been some interesting discussion about using constantly-arriving meteor's trail to reflect wireless signals (MBC: Meteor Burst communications)--could be a backup wireless communication method for dam monitoring, remote (really remote) control, among others. Check ACM Comm's 2004/01 issue.
