subject: WLAN signal coverage is also broad enough to restrict the people through the WLAN radio free access to the Internet [print this page] WLAN Although it is tempting, too, is the mainstream of the future, but because development is not too full, so the WLAN wireless Internet access to wireless "hot spots" is not a lot, WLAN signal coverage is also broad enough to restrict the people through the WLAN radio free access to the Internet, and its "mobility" is also relatively poor. Thus mobile communication has become the preferred wireless Internet access a lot of people, their advantage is that the Internet anytime, anywhere, China Mobile launched GPRS network access based on GSM, China Unicom launched a CDMA-based network CDMA1X, China Telecom is not far behind, PHS introduced to the Internet.
GPRS network is 2.5G Hp pavilion dv6 battery, compared with the other two operators, mobile network coverage in the top slightly better, GPRS network is also true that in some small town, the village has a good performance. But relative to other wireless networks, GPRS speed is not very satisfactory, with almost the last 56K dial-up Internet access, Web browsing, QQ chat naturally no problem, but not for a long time to download files.
CDMA1X belong to the same network and the GPRS as 2.5G wireless communication network. With the GPRS and other wide-area wireless Internet access compared to the speed of performance is the best, the actual download speeds in most areas can also be stable at 10k or so, U-Net said.
PHS network using the benefits of wireless Internet access is cheaper, and with the Modem dial-up costs are the same. But with China Unicom, mobile wireless solutions, the PHS Internet can not be roaming the biggest disadvantage is that, while moving at high speed is not very good performance, which is the same performance of PHS handset.
WLAN
For notebook computers, in order to enjoy the WLAN, no "line" brilliant, is also inseparable from some hardware conditions, such as the basic wireless network card. However, not all laptop have built-in wireless card (pictured above), if the notebook aside and have the antenna MINI PCI slot, we can install their own wireless card, or more simply, is to use a PC card external wireless card (shown below).
