Here is another link from Samsung for B-cdma . Notice at the start they talk of cdma and that at the end go to b-cdma when they talk of the WLL. How it fits together I don't know.samsungelectronics.com The following less the graphics is from their site and couldn't be linked so I pasted it. Some may think it's vaporware and those who do might be in for a huge suprise. Some form of wide band is going to be used soon. The Fixed Subscriber Units and handheld phones are the transceivers to gain access to the system. Different configurations are defined for the product. Indoor and outdoor variants of the FSU(Fixed Subscriber Unit) serving one or multiple subscribers. FSU variants to conventional POTS and ISDN telephones. A handheld terminal for mobility. The RCS(Radio Carrier Station) provides wireline interconnect via the RDU(Radio Distribution Unit) to the switched network, radio frequency interconnect to the subscriber, the capability to process calls, resource management, fault detection and monitoring capability to support the OS. Cost competitive to wired access. Provides functional equivalent of a wireline channel : allows for full range POTS, ISDN,leased lines, and high bitrate (up to 6 *64kbit/s) data services with the same degree ofquality and reliability as today's wireline services. Network wide mobility. Advanced air interface technology for transmission robustness, flexibility(services), and high capacity. Minimization of planning effort-straight forward installion, ease of design verification. Number of cell sites minimized, i.e. radio range up to 30km(urban, roof top scenario: 5km) and high cell capacity Capability to operate in different specific frequency bands (DCS 1800, US-PCS, CEPT 2.0-2.7 GHz). Reliable protection against fraud, unauthorized use invasion of privacy.
