Expanded Information

From a technical point of view, the transmission speed of cable broadband Internet access can reach as fast as 10Mbps for downloads and 1.5Mbps for uploads, and in actual operation, although there are about 500 to 1,000 subscribers who will **** enjoy this bandwidth, the average speed is still 200 to 500kbps.


Data Ready
Email, social media, and cloud apps always updated and available at power on.

Because cable broadband Internet access can quickly deliver large amounts of video, audio, and data, it is possible to use two-way interactive services such as e-banking, home security, utility meter reading, e-shopping, interactive video games, tele-education, telemedicine, karaoke, and video on demand, in addition to the usual Web browsing. With the maturity of future technological development, cable broadband network applications will be even more extensive than can be imagined today.

But wireless communication is changing the corresponding technology to make the transmission rate higher (802,11n rate can reach 100Mbps not less than the wired communication), more stable and convenient, so wireless communication equipment will be the development trend. Wireless communication equipment: satellite, radio, wireless TV (bus or subway), wireless LAN, GPRS Internet access.
