This is not simple (broadband backhaul introduces issues of network jitter/wander online dissertation support groups and recovered clock accuracy but technologies such as the ieee 1588 time synchronisation standard may address the issue. September 24, 2002 Ericsson announces the first live, dual mode wcdma/GSM calls with seamless handover between the two modes and high data rate in live networks September 25, 2002 Mobilkom Austria launches "Europe's First umts-Network" when Boris Nemsic CEO of Mobilkom "video-phoned" the Austrian politican. There are issues in this regard for access point base stations sold to consumers for home installation, for example. He possibly did make the first mobile telephone call.

Race projects were funded by Commission of European Communities (CEC). November 1894 Jagadish Chandra Bose ignited gunpowder and rang a bell at a distance using electromagnetic waves, proving that communication signals can be sent without using wires. The differences are mostly to support differences in access control to support closed access for residential deployment or open access for enterprise deployment, as well as handover functionality for active subscribers and cell selection procedures for idle subscribers. As a result of being relatively close to the femtocell, the mobile phone (user equipment) expends significantly less power for communication with it, thus increasing battery life. A reduction factor of 130 compared to Atlas V launch costs is predicted. Femtocells are also under development or commercially available for GSM, TD-scdma, WiMAX and LTE. The same conclusions were reached for both the 850 MHz (3GPP Band 17) and 2100 MHz (3GPP Band 1) deployments that were studied.
