Wireless Technology Lab

In support of our mission to help bring laboratory technology into the marketplace, Tropper Technologies opens our Wireless Technology Lab.

The Lab will showcase emerging wireless technologies, highlight critical convergence issues, and support a framework for knowledge exchange...


These are exciting times. The wireless communications field is entering the convergence phase at an astounding pace. Coordination amongst and within heterogeneous networks (PAN, WLAN, WMAN, Wireless WAN (2/3/4G Cellular) ) is bringing about a palette of service offerings and features that requires both broad and deep expertise in wireless engineering.

Tropper Technologies Emerging Technologies Group can deliver that domain knowledge. By leveraging our expertise in many of the enabling technologies that will drive this wireless convergence, our Emerging Technologies Group will continue our mission of "Helping to Bring Laboratory Technology to the Marketplace".

Emerging Unlicensed Technologies

There has recently been an explosion of unlicensed wireless standards in the United States within the ISM (FCC Part 18) and U-NII (which is part of the FCC Primary Fixed Wireless band, along with the MMDS and Fixed Wireless Access (FWA) ) categories.  In Europe, the European Telecommunications Standards Institute (ETSI) has created the Broadband Radio Access Networks (BRAN) category.   Similarly, the Mobile Multimedia Access Communication (MMAC) organization has been created in Japan.  This evolving list will help to keep track of and explain some of the more popular flavors.

Emerging Licensed Technologies

Broadband Wireless Access is available now in the licensed spectrum as well.  This includes point to point,  point to multipoint, and point to consecutive point stationary terminals.  BWA to mobile subscribers is also coming shortly via the emerging 2.5 / 3G Cellular/PCS mobile services.  The path is neither clear nor simple.  The economic, political and technical implications are complex.  It is interesting here to create a consistent framework from which we can explore the various options.

On-Line Scratchpad

This simple graphing calculator can be used to explore some
of the inter-relationships amongst the equations that popup
over and over again in our industry.

                       

Usage:

Hit Add Function to popup function input box.

Repeat Add function to overlay graphs.

Hit Delete function to erase last graph.

Hit Rescale to popup graph editor.

Enter your function where x is the only independent variable i.e. sin(x)/(x).

 

Supports:

Common Log [ log10(x) ]

Natural Log [ loge(x) ]

for any base: loga(x)=logb(x)/logb(a)

e

sin/cos/tan functions

for inverse trig functions use 1/sin(x) etc...
