    In this class we'll talk about the WiFi/ bluetooth chip

    2

    00:00:04,233 --> 00:00:10,966

    The WiFi chip is a chip that allows electronic devices to be connected to a wireless local area network

    3

    00:00:11,766 --> 00:00:16,633

    It usually uses 2.4G or 5G radio frequency band

    4

    00:00:17,100 --> 00:00:19,033

    It integrates functional modules

    5

    00:00:19,433 --> 00:00:22,900

    such as WiFi, bluetooth, and radio

    6

    00:00:23,333 --> 00:00:27,533

    Some mobile phones also integrate GPS function module

    7

    00:00:27,966 --> 00:00:32,433

    For example, the picture on the left shows the WiFi chip in a mobile phone

    8

    00:00:33,300 --> 00:00:34,400

    In a mainboard,

    9

    00:00:34,400 --> 00:00:39,300

    the WiFi chip is generally located on the side of the antenna shrapnel port,

    10

    00:00:39,833 --> 00:00:44,000

    which is the position on the side, because the antenna is on the side

    11

    00:00:44,866 --> 00:00:46,133

    At the same time,

    12

    00:00:46,366 --> 00:00:49,400

    there is usually a white filter next to the WiFi chip

    13

    00:00:49,933 --> 00:00:51,533

    Here is a white filter

    14

    00:00:52,033 --> 00:00:55,700

    And the WiFi chip is far away from the radio frequency chip

    15

    00:00:57,633 --> 00:01:00,233

    RF is the management chip for making calls,

    16

    00:01:00,466 --> 00:01:03,000

    accessing 4G and 5G networks

    17

    00:01:04,300 --> 00:01:06,833

    For example, in the picture on the left,

    18

    00:01:07,000 --> 00:01:11,633

    here is the WiFi chip and filter, this is its antenna shrapnel

    19

    00:01:13,500 --> 00:01:17,800

    The common WiFi chip manufacturers in Android phones are as follows

    20

    00:01:18,733 --> 00:01:19,600

    Qualcomm

    21

    00:01:19,800 --> 00:01:22,533

    This is the WIFI chip produced by Qualcomm,

    22

    00:01:22,633 --> 00:01:26,400

    with a capital Q on the surface, starting with WCN

    23

    00:01:27,433 --> 00:01:28,566

    Hisilicon

    24

    00:01:28,966 --> 00:01:37,366

    The model starts with Hi, commonly used are Hi1102, Hi1103, and Hi1105

    25

    00:01:38,266 --> 00:01:39,100

    Broadcom

    26

    00:01:39,266 --> 00:01:41,166

    This is a Broadcom glass chip,

    27

    00:01:41,266 --> 00:01:44,133

    the model number usually starts with BCM,

    28

    00:01:44,366 --> 00:01:46,900

    and is used on some Huawei mobile phones

    29

    00:01:47,300 --> 00:01:48,066

    MediaTek

    30

    00:01:48,333 --> 00:01:51,433

    MediaTek's model numbers usually start with MT

    31

    00:01:52,900 --> 00:01:54,833
