MediumLimitCache¶

//
// Caches various limits and constraints of the radio medium to optimize
// performance. Maintains information about maximum transmission power, minimum
// interference and reception power, maximum antenna gain, communication and
// interference ranges, and other parameters. These limits can be specified
// directly or computed dynamically based on the radios in the network.
