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. Click here for detailed unlicensed technology information. |

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. Click here for detailed licensed technology information. |
