Date codes on the chips indicate this was manufactured in 2010.
The concept is that this is a mini cell tower. If you have bad cell reception, and a decent internet connection, this routes your phone traffic onto your internet link.
Inside of it is a lot of interesting electronics. There are two Soc, one by RaLink (the RT2010F), which presumably handles WiFi and may have a 360 Mhz MIPS processor inside. The other Soc is by PicoChip, the PC202 with an ARM926EJ inside. There is also a GPS module, for reasons you might not expect. It runs linux, a 2.6.24 kernel more or less.
The GPS module is "provided" to ensure that this device is not (and cannot) be used in areas where some legal policy prohibits it. Along with a GPS module to tell the device where it is located, it also has some clever anti-tamper hardware. Notice that the external antenna seems to be for the GPS receiver.
Some of the chips:
WiFi? - Ralink RT2150F GPS - RoyalTek REB-1315LPNX FPGA - Xilinx XC3S400A SDRAM - Winbond W9812G6IH Flash - MX 29LV320DBTI-70G Baseband+ARM9 Processor - picoChip PC202, based on ARM926EJ-S processor SDRAM - Samsung DDR2 K4T51163QG-HCE6 Flash - Spansion GL512P10FFCR2 Ethernet Transceiver - SMSC LAN 8700c-aeczThe PicoChip PC202 is perhaps the most interesting part on the board. This is an English company making unique mulicore DSP devices. Interestingly there is an ARM logo on the part as well. The ARM 926EJ is an older ARM (arm v5) with an 8-bit "Jazelle" mode. This is from the 1998-2006 era and is pretty long in the tooth these days. On many units, the PC202 has a heatsink mounted on it.
The only thing I might consider doing with the unit I have is to extract the GPS receiver from it. Rumor has it that it talks serial with standard NMEA sentences inside the unit.
