Today we’ll be taking a look at the Optus Huawei E960 3G Wireless Gateway (user guide) which is a 3G 802.11b/g hot spot with 4x 10/100 network ports, RJ45 port for connecting your phone and a USB port for power / ability to act as a modem on your PC.

4 screws later and we’re in, the top just pops right off without any effort.

We’ve got a 2 board construction with a 16 pin interconnect and lots of shielding for each major component. There’s 3 antennas mounted on a plastic base which are screwed in place, I guess the reasoning could be that they are easily replaceable to suit the frequency band that’s needed. PCB date code is 36th week of 2007.

There’s a DC-DC converter under one of the shields, we’ve got the processor, RAM, flash and the Wifi power amplifier.

We’ve got another DC-DC converter for the USB input in a shield, a 250V 10uF cap with a transformer in another shield and some phone circuity with 2x FZT655 150V NPN transistors. There’s also a shield with 2 missing ICs and an low profile AVF 22mF 4.5V SMD cap. They have a module which has been soldered down that has the 3G main ICs.
