Enhancing power efficiency in a wireless internet card

An apparatus comprising:

• a front end comprising shared frequency resources,
• a first wireless block coupled to the front end,
• a second wireless block coupled to the front end, wherein the second wireless block is to send a request to the first wireless block to use shared radio frequency resources, and
• a coexistence block coupled to the second wireless block and the first wireless block, wherein the coexistence block is to wait for a time duration to elapse after the request is received and to allow the second wireless block to use the shared radio frequency resources if the time duration is elapsed, wherein the first wireless block is to operate in a low-power mode while the second block is allowed to use the shared radio frequency resources.

A system comprising:

• a processor,
• a chipset coupled to the processor, and
• a wireless internet card couple to the chipset, wherein the wireless internet card comprises, a front end comprising shared frequency resources,
• a first wireless block coupled to the front end,
• a second wireless block coupled to the front end, wherein the second wireless block is to send a request to the first wireless block to use shared radio frequency resources, and
• a coexistence block coupled to the second wireless block and the first wireless block, wherein the coexistence block is to wait for a time duration to elapse after the request is received and to allow the second wireless block to use the shared radio frequency resources if the time duration is elapsed, wherein the first wireless block is to operate in a low-power mode while the second block is allowed to use the shared radio frequency resources.
