  Is Bluetooth a Viable Alternative to 802.11b?

Response to: RE: 802.11b and Bluetooth coexist


Can someone tell me what Bluetooth does that 802.11b CANNOT? Reading Wei-Meng's article, I get the impression that BT is merely a "me too" type technology. An earlier post claims that BT is better for connecting computers and 802.11b is better for networking. But what's the difference? Doesn't a 802.11b based home LAN (or HAN) necessarily "connect" home computers together?


I'd appreciate if someone could clarify this for me.

    It a PAN (Personal Area Network) not a WLAN (Wireless Local Area Network). No roaming supported.

    Due to Bluetooth simplicity it can be emplemented in a single chip without any support from a coprocessor or network stack. It contains everthing needed. A phyical radio, BaseBand processor, MAC processor, Protocol stack, and stand alone application tasks. It is a SOC (System On Chip) and as such does not need any other CPU/OS/Network stack support.

    Try to put a WiFi radio and battery in your ear like you can with bluetooth ear fob.
