[{$pagename}] is a wireless communications protocol that runs at the seemingly unimpressive maximum speed of 250 kb/sec. That's bits, not bytes. Most people that have heard of wireless communications usually think of IEEE 802.11 or Bluetooth , since those are the most mass-market consumer protocols available. So why in the world would we need another wireless protocol that runs at a turtle's pace?

The reasons behind 802.15.4 lie in its application domain: short range wireless networking. One of the biggest obstacles to using wireless devices is power consumption, since there is usually no power cable available to a mobile wireless device. 802.11 was designed for large data transfers with a tethered device like a wireless router spewing out gobs of RF power. On the receiving end, the laptops with Wi-Fi connections usually have a large (ie: big-ass by consumer mobile standards) battery that can run an 802.11 transceiver for hours at a time. [2]
