Not a silly question at all. In fact, it's a very good question. Yes and no. The N210 device is capable of operating in a similar configuration, but the implementation is more complicated and, more importantly, does not exist. The reason is that the N210 uses a fixed FPGA clocking frequency that doesn't match up well with the polyphase channelizer used for multiplexing. The B200/B210 has configurable clocking so that the desirable sampling rate for GSM channel spacing can be used. -TT
