Summary
• The existing commercially available 2.4 GHz IEEE 802.15.4 silicon can be classified into low, mid and high tiers
• The battery life for even the high tier class falls short of expectation
• Target life time is reiterated (1 year for coin shaped and multiple years for AA)
• Next generation transmit/receive currents roughly 250 mA
