ETSI – European Telecommunications Standards – ETSI produces globally-applicable standards for Information and Communications Technologies (ICT). Includes – Fixed, mobile, radio, converged, broadcast and internet technologies.

ITU-T – Infocommunications Standards – “ITU-T Recommendations are defining elements in information and communication technology (ICT) infrastructure. Whether we exchange voice, data or video messages, communications cannot take place without standards linking the sender and the receiver. See ” Telecommunication Standardization Bureau” TSB

CDG – 3G Wireless CDMA Development – “The CDMA Development Group (CDG), founded in December 1993, is an international consortium of companies who have joined together to lead the adoption and evolution of 3G CDMA wireless systems around the world.” See also CDMA Technology

3GPP – Mobile Broadband Standard – “The original scope of 3GPP was to produce Technical Specifications and Technical Reports for a 3G Mobile System based on evolved GSM core networks …” Global System for Mobile communication (GSM), GPRS and EDGE.

IEEE – Broadband Wireless Access Standards – “The IEEE 802.16 Working Group on Broadband Wireless Access is creating the IEEE 802.16 family of WirelessMAN Standards for Wireless Metropolitan Area Networks.”

Microchip PIC – Wireless Connectivity Design

“Ethernet communication solutions offer access to the most widely deployed networking system. The TCP/IP protocol, which is at the core of this technology, allows total location independence and interoperability to any embedded application.”.

MRF24J40MA 2.4 GHz IEEE 802.15.4 radio transceiver module

  • Ethernet
  • TCP/IP
  • ZigBee
  • MiWi

“The emerging standard for flexible wireless networking specifically designed for embedded control. ZigBee supports stars, clusters and mesh networks of up to 64k nodes. Microchip supplies a free stack that supports a variety of transceivers.”

MRF24J40MA 2.4 GHz IEEE 802.15.4 radio transceiver module.

Has a integrated PCB antenna, matching circuitry, and supports ZigBee too. Connects to many PICs via a 4-wire SPI interface. You can design wireless sensor networks and home automation systems.

The days of Voice Communication are coming to an end. In fact it has been happening in the background all along. It is Digital Replacing Analog Everywhere. Voice is now data. In the future Voice Communication is just an App you need to buy as an option. Whatever the struggle between technologies, The future communications will be just Broadband Wireless Devices with Voice, Data and Web all in one. The intermediate technologies we see today, the Transitional Technologies are part of a Large Learning Curve. The future may be more of Optics, WiMax and more like Any Device can do [Read More ....]

USB Drive to iPod File Transfer

I had to put some files from my USB ThumbDrive to iPod. That needed a Turn on, on my computer and then plugging things on, and a transfer. I saw this innovation earlier. Wireless USB – Wireless Extension to USB. And also a USB Drive like product. I feel this type of thing can be made for stand alone iPod, extra storage or archive. No need to turn on PC. Also, i think, there may be a need (?), for a very small, tiny Wi-Fi Router with 100 GB storage, media and cache management. That can serve 2 or 3 [Read More ....]
