A method of operating a radio frequency "RF" network so that extant cable system infrastructure is used to enable intra-network mobility of a client device, the method comprising: transmitting orthogonal frequency division multiplexing "OFDM" waveforms over at least a portion of the extant cable system infrastructure; receiving at least a portion of the transmitted OFDM waveforms via a premises device disposed at a premises (1102, 1202, 1302, 1402); receiving at least a portion of the transmitted OFDM waveforms via a radio device external to the premises (1104, 1204, 1304, 1404); enabling establishment of a radio frequency connection between the client device and the premises device (1106, 1206, 1306); the method characterized by: determining that the established radio frequency connection is insufficient to meet one or more quality of service "QoS" requirements required by the client device (1208, 1308); based on the determining, causing establishment of a radio frequency connection between the client device and the radio device external to the premises, via use of one or more antennas associated with the premises device, to supplement the radio frequency connection between the client device and the premises device for at least a period of time (1112, 1214, 1312); and utilizing both of the radio frequency connections between (i) the client device and the premises device, and (ii) the client device and the radio device external to the premises, to cause delivery, via the premises device, to the client device of the at least first portion of the OFDM waveforms received by the premises device and the at least second portion of the OFDM waveforms received by the radio device external to the premises, respectively, such that the one or more QoS requirements are met. transmitting orthogonal frequency division multiplexing "OFDM" waveforms over at least a portion of the extant cable system infrastructure; receiving at least a portion of the transmitted OFDM waveforms via a premises device disposed at a premises (1102, 1202, 1302, 1402); receiving at least a portion of the transmitted OFDM waveforms via a radio device external to the premises (1104, 1204, 1304, 1404); enabling establishment of a radio frequency connection between the client device and the premises device (1106, 1206, 1306); the method characterized by: determining that the established radio frequency connection is insufficient to meet one or more quality of service "QoS" requirements required by the client device (1208, 1308); based on the determining, causing establishment of a radio frequency connection between the client device and the radio device external to the premises, via use of one or more antennas associated with the premises device, to supplement the radio frequency connection between the client device and the premises device for at least a period of time (1112, 1214, 1312); and utilizing both of the radio frequency connections between (i) the client device and the premises device, and (ii) the client device and the radio device external to the premises, to cause delivery, via the premises device, to the client device of the at least first portion of the OFDM waveforms received by the premises device and the at least second portion of the OFDM waveforms received by the radio device external to the premises, respectively, such that the one or more QoS requirements are met. determining that the established radio frequency connection is insufficient to meet one or more quality of service "QoS" requirements required by the client device (1208, 1308); based on the determining, causing establishment of a radio frequency connection between the client device and the radio device external to the premises, via use of one or more antennas associated with the premises device, to supplement the radio frequency connection between the client device and the premises device for at least a period of time (1112, 1214, 1312); and utilizing both of the radio frequency connections between (i) the client device and the premises device, and (ii) the client device and the radio device external to the premises, to cause delivery, via the premises device, to the client device of the at least first portion of the OFDM waveforms received by the premises device and the at least second portion of the OFDM waveforms received by the radio device external to the premises, respectively, such that the one or more QoS requirements are met.
