It has been good to meet with John Edwards of picoChip at congress with whom I’ll be holding the WiMAX course at the University of Oxford later this year together with Chris Beardsmore of Intel. Since my scope of interest in wireless ranges from layer one to the application on the top I very much enjoyed to see picoChip’s latest chip for LTE and WiMAX base stations in action. While others use Asics for the lower layer protocol handling and decoding, picoChip has designed their own chip with an ARM 9 processor and their own DSP to do the job more flexibly. The ARM processor used for the higher levels of the protocol stack runs Linux and the chip is used both for WiMAX and LTE. Looks like their solution has become quite popular as their WiMAX implementation has been chosen by testing houses as the reference design all other WiMAX companies have to test against. Chris allowed me to take a picture of their base station reference board and you can find it in my 3GSM Flickr stream on the right of the page.
