Wireless technologies have become a crucial part of all Apple devices that delight our customers. Our devices operate in radio environments with various applications, using different wireless technologies. With the latest developments in cellular, WiFi, BT, etc. we utilize a sophisticated simulation platform to study performance of our devices in complicated radio and network conditions. We are looking for an expert wireless systems engineer who has deep understanding of wireless protocol interactions within the network, interactions across different layers of wireless protocols, such as WiFi or BT, and interactions of different technologies within the same device. You will be responsible for modeling the network protocols as well as the effect of the wireless channel and RF interactions of different wireless technologies in the simulation platform. In addition, provide reference simulations and conducting particular studies using the simulation platform.
