Did you read this ? 14,400 aint nothing to brag about? It won't be a big thing in any industry . ISSUE #6 TUESDAY 27 JANUARY 1998 CDMAOne Packs New Punch With Packet Data Solution By Jeremy Scott-Joynt CDMAOne is to become the first cellular standard to offer packet-switched data transmission without having to resort to an overlay network. Qualcomm has unveiled a new base station controller, called the QCore, for its range of CDMAOne infrastructure. The new kit offers circuit-switched data and fax traffic as standard, but under a protocol named IS-707 can be software configured to connect directly to an IP router . The equipment will go on sale at the end of March. According to Qualcomm , users of IS-707 packet-switched data services will be able to access the Internet at a speed of 14.4kbps. They will also be able to connect a laptop computer or or other mobile data device directly to a CDMAOne phone to transmit and receive data, because the BSC includes software modems. According to Qualcomm, the entire system is software, not hardware, driven. The base station allocates its resources dynamically depending on demand, without setting aside processor time specifically to each of the three functions - fax, data and voice - it can support. The development of packet data is seen as vital for cellular operators if they are to boost the takeup of data services ahead of third generation systems. Packet switching offers promises essential improvements in spectrum efficiency. While circuit-switched data locks up a slice of spectrum for the duration of the call, packet switching sends small chunks of information through the network as and when requested. So, whereas the dead time between bursts of data is lost in a circuit-switched data system, packet switching allows many data streams to use the same frequency sequentially, since every packet is tagged with the information needed to identify the intended recipient. GSM still lacks an operational packet-switched architecture. The General Packet Radio System (GPRS) - which promises speeds of 144kbps - is set to be rolled out in 1999, although operators are nervous of the expected cost of deployment so close to the onset of 3G. The only existing packet-switched data service over a public network is Cellular Digital Packet Data, which at the moment runs over AMPS networks in the US. But since CDPD needs an expensive overlay network, coverage is patchy, and according to US consultancy the Strategis Group had only 17,000 subscribers at the end of 1997, mostly because of competition from dedicated data networks like Ardis. Subscriber numbers, Strategis predicts, would climb to nearly 70,000 by the end of this year - but income per subscriber was set to drop from $41 to $36. [
