PCB News - Modules that pcb layout engineers should be familiar with

The following are several modules that are often encountered in PCB design. As a PCB layout engineer, you should be familiar with these.
I-mode and CHTML

I-mode is a wireless communication service launched by DoCoMo, a subsidiary of Japan Telecom (NTT), in the Japanese market. It is currently the wireless Internet service with the most users in the world (all in Japan). I-mode and WAP

The main difference of is that the content of I-mode is written in CHTML, so most of the current network content can be used with minor modifications; while WAP uses WML, PCB

Layout training Existing web content must be converted to WML before it can be used by WAP.

CHTML (Compact HTML) a variant of HTML. Most compatible with HTML.

-----------

Bluetooth (BlueTooth)

Bluetooth is a radio technology that supports short-distance communication (generally within 10m) of devices. PCB

Layout design training enables wireless information exchange among many devices including mobile phones, PDAs, wireless headsets, notebook computers, and related peripherals. Its standard is IEEE802.15. Work at 2.4HGz

frequency band. Bandwidth is 1Mb/s

(Note: The name Bluetooth is very interesting. It comes from the name of the Scandinavian king who unified Denmark and Sweden in the 10th century.)

-----------

Wireless LAN

Wireless local area network is developed from local area network. The standards are IEEE802.11, IEEE802.11b and IEEE802.11a. Of which 802.11b

Works in the 2.4GHz frequency band with a bandwidth of up to 11Mbps. 802.11a is defined in the 5GHz frequency band, and the bandwidth is expected to reach 54Mb/s. But accordingly, Wireless

HomeRF

HomeRF is a wireless radio frequency technology mainly designed for home networks. It is a combination of IEEE802.11 and DECT to reduce costs. HomeRF also uses spread spectrum technology and works in the 2.4GHz frequency band. The current bandwidth of HomeRF is 1 to 2Mb/s, and it will increase to 10Mb/s in the future.

SyncML

SyncML is an industry-wide mobile data synchronization protocol. Use SyncML to keep the data on the mobile device synchronized with the remote data. By Ericsson, IBM, Lotus,

Developed by an association composed of companies such as Matsushita, Motorola, Nokia, Palm, Psion, and Starfish Software.

The above is the introduction of several modules that PCB layout engineers should be familiar with. Ipcb is also provided to PCB manufacturers and PCB manufacturing technology
