Embedded microchannel cooling package for a central processor unit

A method for identifying a location of an asset in a communication network, said network having a first receiver device at a first station and a second receiver device at a second station, each receiver device having a known position, said method comprising:

• estimating more than one first time-of-arrival value, said first time-of-arrival value corresponding to arrival at said first station of an 802.11 communication signal from said asset;
• estimating more than one second time-of-arrival value, said second time-of-arrival value corresponding to arrival of said communication signal at said second station;
• calculating a time-difference-of-arrivals using said first and second time-of-arrival;
• estimating said asset's location based on the calculated time-difference-of-arrivals at said first and second receiver devices.

A method for identifying a location of an asset in a communication network, said network having at least three receivers, said method comprising:

• estimating a time-of-arrival of an 802.11 communication sequence at said receivers;
• collecting at least one time-of-arrival estimate for each of said receivers, said estimate corresponding to a time-of-arrival of said communication sequence at a respective one of said receivers;
• calculating a difference for each of at least two pairs of said estimates;
• and
• estimating said asset's location using only said calculated difference for each of at least two pairs of said estimates.
