We are team 4322A, Bahrainotics.  We chose to disassemble a router because it is widely used for important services that we use daily and because it has many electronic components that we can learn about.   Huawei router is a networking device that has the following characteristics of every other router as it forwards data packets between computer networks. Huawei device has the following special  characteristics among other routers : Support speeds up to 150 Mbps 4 Ethernet ports for wired connection Support network environments. Frequency division duplex (FDD): 2600/2100/1800/900/800 MHz Supports Windows XP, Windows Vista, Linux, Mac OS X. Compatible with browsers include Internet Explorer, Firefox, Chrome and Safari                                                                                      After disassembling the device, we saw an ordinary motherboard that had one open and close button on the bottom right and three others on the bottom left. Upper button WTS open button, the middle button to restart the router and the bottom button is for the wireless LAN service. There are also 4 LAN ports, 22 TEL ports, USB port and power input. Also, there were Ethernet magnetics between LAN ports and the LTE module that are used to connect between the LAN ports and the processor.                                                                                      As for the chips found, on the left of the three buttons was a Broadcom BCM5358 SoC chip, Spansion 16MiB SPI flash and Hynix 128MB DRAM. Above the LAN ports there were e4 32178-FM chip and DELTA LFE8731 processer. Generally, the chips are more enhanced than the previous editions, they reduce the number of system components on-chip, which lowers the rest-of-bill-of-materials (RBOM) cost by up to 35 percent.     From this simple but inspiring experience, we gained more knowledge about routers, useful acronyms such as LAN while researching, learned about different electronic components that are widely used in other gadgets and so on.
