Definitions
- the present invention relates to broadband wireless communication technologies, and more particularly to an application solution and apparatus for wireless local area network (WLAN) access of a microwave access global interoperability (WiMAX) terminal device.
- WLAN wireless local area network
- WiMAX microwave access global interoperability
- WiMAX is the abbreviation of World Interoperability for Microwave Access. It is based on the IEEE 802.16 standard and provides point-to-multipoint broadband wireless access in a J3 ⁇ 4 domain multi-vendor environment. Therefore, WiMAX is also often used. It is called IEEE Wireless MAN (Metropolitan Area Network). The technology involves the work of two international organizations: the IEEE802 Standards Committee 802.16 Working Group and the WiMAX Forum. The IEEE 802.16 working group is the standard setter; the WiMAX Forum is the promoter of the IEEE 802.16 technology. The standard evolution and application modes are introduced separately. So far, the IEEE 802.16 standard series includes 802.16, 802.16a 802.16c, 802.16d, 802.16e, etc.; Table 1: Basic introduction of WiMAX protocol
- WiMAX is a standards-based technology that replaces existing wired and DSL connections to provide last-mile wireless broadband access. WiMAX will provide wireless broadband connectivity in fixed, mobile, and portable formats, and will eventually provide mobile wireless broadband connectivity without the need for direct line-of-sight base stations. In a typical 3 to 10 mile radius unit deployment, fixed and portable access applications provide up to 40 Mbps per channel, which can simultaneously support hundreds of commercial users using T-1 connection speeds or thousands of DSL connection speeds. The needs of home users and provide enough bandwidth. Mobile network deployments will be able to deliver up to 15 Mbps in a typical (highest) 3 km radius cell deployment. Wireless Local Area Network (WLAN) technology is defined in the IEEE 802.11 specification series.
- the series currently includes the following four specifications: 802.11, 802.11a, 802.11b, and 802.11g. All four protocols use Ethernet protocol and carrier sense multiple access/collision avoidance technology (CSMA/CA, instead of CSMA/CD) for channel sharing.
- CSMA/CA carrier sense multiple access/collision avoidance technology
- 802.11 - for wireless LANs using the 2.4 GHz band, with a transmission rate of 1 Mbps or 2 Mbps; supports both frequency hopping (FHSS) and direct sequence spread spectrum (DSSS).
- 802. l la-802.ll extension using 5 GHz band, transmission rate of 54 Mbps;
- 802.11a supports Orthogonal Frequency Division Multiplexing (OFDM) coding, but does not support FHSS or DSSS.
- 802.11a is used in wireless ATM systems and is used to access hubs.
- 802.11M is also known as the 802.11 high-rate-802.11 extension, which uses the 2.4 GHz band and has a transmission rate of 11 Mbps (and possibly down to 5.5 Mbps, 2 Mbps, or 1 Mbps).
- 802.11b only supports DSSS. 802.11b is a revised version of the original 802.11 standard that implements Ethernet-like functions wirelessly. 802. l lg- supports short-range wireless transmission, using the 2.4 GHz band, with a transmission rate of 20 Mbps to 54 Mbps. 802. l lg supports OFDM coding. WLAN single wireless coverage AP provides good coverage for users ranging from 100 meters to 500 meters.
- Existing WiMAX terminal access devices are available in the following forms: USB WiMAX wireless data card, PCMCIA wireless data network card, RJ45 Ethernet access wireless WiMAX MODEM, among which USB WiMAX wireless data card and PICMAC wireless data network card are mainly 40 pairs. A customer group with high mobility requirements can achieve data access in the case of high-speed mobility.
- RJ45 Ethernet access wireless WiMAX MODEM is mainly for home users and small and medium-sized enterprise users to WiMAX network applications. Due to the limited number of Ethernet interfaces for wireless WiMAX MODEM that provides RJ45 Ethernet access, the number of users that can be supported is often limited. The limitation (generally providing 2 RJ45 interfaces) limits the access of more users to the network. Moreover, in the process of use, the computer network card and the WiMAX MODEM must be connected through a twisted pair cable, which is often troubled by the network cable in the application, mobility. Obviously insufficient, and uncertain factors such as aging of the network cable may also affect the normal use of the network. The present invention has been made in view of the above problems.
