"Conversion tables for return loss, reflection coefficicient, and SWR with values for interaction of a small phasor (utility reference) expressed in dB related to the reference.

In microwave circuit design S-parameters are very useful for the full characterisation of any 2 port network. In contrast to z,y and h-parameters, which require broadband short circuited and open circuited connections at the TEST ITEM for the measurement,

S-parameters are determined with input and output terminated with the resistive characteristic impedance of test systems (generally 50 ohms in a coaxial line system). Parasitic oscillations in active devices are minimised when these devices are terminated in resistive loads."

Wireless Communications now have voice, data, media. It has capability of the Internet, making a portable device part of the World Wide Web. There are companies and institutions that are making this utopia of a connected world possible with the systematic approach.



Now with IoT, WSN and M2M a complexity arises. Robots, Drones, Automobiles and Machines have wireless connectivity with an IP address or a Phone Number. All this is possible when we think of technologies more like Wi-Fi and WiMax merging with mobile-cellular systems. We have to abandon the Towers and go for Modular Daisy Chain of Repeaters on Street Poles and Fiber Optic Nodes. Maybe like these folks say LightRadio Antenna Module

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."

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 Anything. Not Convergence but more an Intermeshed Collage.

This RF is also a Tough Science and needs Authentic and Highly Skilled Engineers to design and develop the technologies for the future. The Budget of the Average consumer will be less, the appetite enormous. The Business Models complex and very challenging. The customer potential is 100% and it will work only if it is affordable and planned carefully. It is not as easy as it looks.
