Chinese telco Huawei Technologies and Netcom, a subsidiary of Norway’s TeliaSonera, are demonstrating live services over the world’s first commercial LTE (Long Term Evolution) network in Oslo.
LTE is widely seen as a successor to 3G networks. It allows applications that have a high requirement on bandwidth such as video on demand, video streaming, FTP, web surfing, video conferencing and video telephony. In Oslo these were demonstrated under real network conditions.
Putting it in words that run trippingly off the tongue, we are told the adoption of key LTE technologies such as MIMO (multiple-input/multiple-output) and OFDM (orthogonal frequency division multiplex) allows the network to deliver download peak data rates of up to 150Mbps in a single LTE cell with multiple terminals.
Quite so. Never heard it put better or more clearly.
All of this has happened (in a sense) because of a Hollywood film star and a composer. True.
The star was Hedy Lamarr and the composer, George Antheil. He had experimented with automated control of musical instruments including his music for Ballet Mecanique.
Together, Hedy Lamarr and George Antheil submitted the idea of a secret communication system based on frequency hopping in June 1941. On August 11, 1942, U.S. Patent 2,292,387 was granted. This early version of frequency hopping used a piano roll to change between 88 frequencies.
This frequency-hopping idea serves as a basis for modern spread-spectrum communication technology, such as COFDM used in WiFi network connections and CDMA used in some cordless and wireless telephones.
Top, as they say, that.
