re: Ericsson - The Turnkey cdma2000 Threat to Nokia - 802.11b and 3G
Significantly, Ericsson is deliberately targeting operators running TDMA networks with its CDMA technology. It argues that the ANSI-41 based back-end systems of the TDMA operators can be migrated over to CDMA. By contrast, Nokia, with 800 MHz GSM technology, has been encouraging TDMA operators to move to GSM. There are presently around 16 handset manufacturers supplying CDMA handsets, however. Ericsson claims to be the only manufacturer with a complete CDMA solution, providing the base stations, the switches, the IP integration, and CDMA handsets from the same source.
>> Ericsson Shows Live 3G Link With Wireless Ethernet

The ability for wireless Ethernet (802.11b) and 3G technologies to happily coexist was proven by Ericsson at the 3G CDMA World Congress in Hong Kong Tuesday.
Ericsson's live demo shows a portable PC 'roaming' from a high-speed 3G CDMA network connection onto an industry standard wireless LAN (W-LAN) and then back again.
The demo involves a laptop computer fitted with both a CDMA modem and a standard 802.11b NIC (Network Interface card). While the NIC cards are already shipping, the CDMA modem is still a prototype (whose physical size dwarfs a Compaq iPAQ, for example).
Ericsson claims the demo rig is 3G compliant, working to the CDMA2000 1xEV-DO standard. The latter offers speeds up to 2.4 megabits per second, although actual demonstrated speeds were closer to 700Kbps when attendees were shown a video clip of the forthcoming Lara Croft film being streamed to the PC.
The Ericsson cards that add an 802.11b capability to a CDMA base station are already available for operators that wish to learn how to support their paying subscribers with a WLAN capability - in airports and at train stations, for example. Suitable 1xEV cards are not expected until at least Q4 2001.
Ericsson's demo counters claims from companies such as Jippii that installing public 802.11 base stations can dispense with the need to roll out expensive 3G networks. W-CDMA and 802.11 working together has yet to be shown, although GSM and 802.11 co-existence is commonplace.
