Types of Deployments
Tx power calibration algorithms essentially use mobile feedback to learn key information such as required coverage range, surrounding RF environment and impact of interference. Power calibration algorithms are developed for two different deployments: residential and enterprise.
Residential small cell deployment typically refers to single-femto deployment in a consumer’s home or apartment, whereas enterprise small cell deployment generally refers to multi-femto deployments such as enterprise buildings, small offices, and shopping malls.
- ResidentialFor residential deployments, an adaptive scheme to calibrate Tx power using feedback from home and macro users is developed. Further, to protect nearby active macro users, an algorithm has also been developed to throttle small cell Tx power in real-time by detecting the presence of such users.
For enterprise small cell deployments, a framework of coverage planning and Tx power calibration based on technician assistance is developed. A distributed algorithm for multi-femto transmit power calibration has been designed to provide good small cell coverage indoors and within the enterprise with minimal leakage to outdoors and outside the enterprise.
