Abstract
Systems and techniques for management of an antenna tuning frequency range. Frequency coverage needed for an antenna used in a portable communications device in a wireless communication network is determined based on communication protocols being used, with an active tuner being connected to a passively tuned antenna when a different frequency range is called for and with the active tuner being effectively isolated when only the range provided by the passively tuned antenna is needed to reduce the risk of RF mixing or intermodulation.
Claims20
An apparatus comprising:
- at least one processor;
- memory storing computer program code;
- wherein the memory storing the computer program code is configured to, with the at least one processor, cause an apparatus to at least:
- determine a frequency range to be covered by a portable communications device operating in a wireless communication network;
- and
- control one or more connections between an active tuner and an antenna passively tuned to one or more specified frequency ranges, so as to select coverage of the one or more specified frequency ranges to which the antenna is passively tuned, or one or more frequency ranges that are different from the specified frequency range by the antenna in combination with the active tuner.
A method comprising:
- determining a frequency range to be covered by a portable communications device operating in a wireless communication network;
- and
- controlling one or more connections between an active tuner and an antenna passively tuned to one or more specified frequency ranges, so as to select coverage of the one or more specified frequency ranges to which the antenna is passively tuned, or one or more frequency ranges that are different from the specified frequency range by the antenna in combination with the active tuner.
A computer readable medium storing a program of instructions, execution of which by a processor configures an apparatus to at least:
- determine a frequency range to be covered by a portable communications device operating in a wireless communication network;
- and
- control one or more connections between an active tuner and an antenna passively tuned to one or more specified frequency ranges, so as to select coverage of the one or more specified frequency ranges to which the antenna is passively tuned, or one or more frequency ranges that may be different from the specified frequency range by the antenna in combination with the active tuner,
