Comparison of Three Types of wireless network coverage

The wireless access technology, in full swing, can achieve different wireless network coverage. So how should we choose different environmental features? This will be analyzed from these wireless access technologies and wireless network types. The following describes the coverage of three types of wireless networks.

1. WLAN: indoor wireless network coverage

WLAN is not only suitable for the establishment of an indoor wireless LAN, but also for the establishment of a wireless LAN with a neighbor within 300 to share the internet. 802.11b is further extended based on 802.11, and 802.11b works between 2.400 and ~ In the 2.483 5 GHz band, the dynamic transmission rate is implemented, and the data rate can be adjusted at a rate of 1 Mb/s, 2 Mb/s, 5.5 Mb/s, and 11 Mb/s Based on the noise condition; 802.11g is a hybrid standard that provides 11 Mb/s data transmission rate in the 2.4 GHz band, and 54 Mb/s data transmission rate in the 5 GHz band. The 802.11g standard can be backward compatible with the 802.11b standard. However, the 802.11a standard is incompatible with the 802.11b/g standard. It is recommended that you do not select the IEEE 802.11a standard product.

2. WiMax: High-Speed and wide-range wireless network coverage

WiMax is Intel's 802.16 wireless Internet technology. WiMax has the advantages of high data transmission rate, simple deployment, and limited by geographical conditions, it supports a data transmission speed of up to 70Mpbs over a distance of 30 miles between base stations, far exceeding the capabilities provided by existing wireless access technologies. WiMax can be used as an extension or supplement for other access methods. For example, the ADSL access method has a line distance limit of 3 to 5 kilometers, so some areas that cannot be covered will appear in some remote areas, if a carrier uses WiMax as a transfer station for DSL connection, it can expand its access service coverage. Using WiMax technology, the current Internet access method will change, and people will enter an era of non-differential Internet access.

3. Bluetooth: short-distance indoor wireless network coverage

Bluetooth is a wireless technology that supports up to 10 meters of short-distance communication between devices. The standard of Bluetooth is 802.15, which is in the 2.4 GHz band and has a bandwidth of 1 Mb/s. There is a networking method in the LAN formed by bluetooth: one is PC-to-PC networking; the other is PC-to-Bluetooth Access Point networking. The PC-to-Bluetooth Access Point networking is consistent with the WLAN method, it's just that the device procurement is different. However, because there is only 10 meters of transmission distance, Bluetooth is only suitable for indoor wireless LAN construction, and the distance between the computer and the computer cannot exceed 10 meters.
