Facilitation of access point authenticated tunneling for 5G or other next generation network
When an access point device is aware of an internet access failure, the access point device can attempt to re-route the baseband content through a different access point for the purpose of using its hard-wired internet connection. An administrative function can allow the access point device to tunnel through the internet service provider (ISP) of another access point device if permission is granted to do so. The permission can be granted beforehand or it can be granted to on the fly. Consequently, if the packets cannot route via the normal, hard-wired path, a message to a secondary transceiver of the access point device can instruct the access point device to find an alternate path via the ISP of the other access point device. |

Voltage rotator for high switching frequency PWM inverter
A motor controller executing a current regulator and a modulation routine in separate update intervals provides an improved fundamental voltage waveform for a motor controlled by the motor controller. The current regulator is executed at a first periodic update rate and the modulation routine is executed at a second periodic update rate, where the frequency at which the modulation routine executes is at least twice the frequency at which the current regulator executes. Executing the current regulator and the modulation routines at different frequencies results in the current regulator generating a single voltage reference signal for multiple periods of the modulation routine. To reduce voltage ripple induced by decoupling execution of the current regulator and the modulation routine, the motor controller extrapolates the voltage reference generated by the current regulator into multiple voltage reference signals, where a unique voltage reference signal is provided for each period of the modulation routine. |
