Apple. And what does the job entail? Among other duties, "Implementation, Integration, customization, enhancement and maintenance of L1-3 Protocols for one or more of the following air interface: GSM/UMTS, CDMA (1x/EVDO), LTE etc." You read that right, LTE. It's not the first time we've seen such the technology listed (hello there, since-removed "Cellular Technology Software Manager" job posting), but at the same time, it's not surprising that Apple's looking to the future. Just don't get your hopes up for an LTE iPhone or iPad in the near future.
