How to set up a computer's wireless network bridging?

Bridge, can make the two places interlinked. So how do two separate wireless networks connect to each other in a wireless network? This will require the wireless bridge we are introducing now. Presumably, by this name, we all know its role. Here, our focus is to introduce what the wireless network Bridge means and how to carry out the wireless network Bridge settings.

Before you know the wireless Bridge Setup, let's take a look at what is the wireless network Bridge.

As the name implies is the bridge of the wireless network, it can set up between two or more network communication Bridge (wireless network Bridge is also a branch of wireless AP). Wireless Bridge In addition to the basic features of the cable network Bridge, wireless network Bridge work in 2.4G or 5.8G wireless license-free band, and therefore more convenient than other wired network equipment deployment.

Its transmission standards are often 802.11b or 802.11g, 802.11a Standard, 802.11B standard data rate is 11Mbps, in the maintenance of sufficient data transmission bandwidth, 802.11B is usually able to provide 4Mbps to 6Mbps actual data rate, And the 802.11g, 802.11A standard wireless network Bridge has 54Mbps transmission bandwidth, its actual data rate can reach 802.11b 5 times times.

In the manufacturer's promotional description, although many wireless AP or wireless routers also have the bridge function, also known as the wireless Network Bridge, but we talk in this article in the Wireless Network Bridge strictly refers to the transmission distance of more than 1-20 kilometers of products, and not like a normal wireless AP or wireless router in the range of hundreds of meters bridge.

Establish communication links between two points (e.g. headquarters and branch offices, network centers and communities). From the customer's needs and actual survey of the situation to see transmission mode, and the appropriate wireless network Bridge settings, there are the following modes of transmission:

(1) AB two points between the visible, no obstacle blocking, no electromagnetic interference, or small interference; The distance between AB two points is in line with the communication distance of bridge equipment.

Can use the point to point Way direct transmission: a building to place a wireless network bridge, the top placement side directional antenna; B building also placed a bridge without a network, the top of a directional antenna. Wireless network bridge between the two places through the feeder and the local antenna connection, two point of wireless communication can be quickly built up. Wireless Network Bridge through the Super five-type twisted-pair cable to connect all over the network switch. So the two networks can be integrated.

(2) AB Two is not visible between, but between the two can be seen indirectly through a C building. and AC two points, BC two points to meet the requirements of Network Bridge equipment communication.

We use relay mode, C building as a relay point. AB Each place the network bridge, directional antenna.

C-point options are:

Place a network bridge and a side omni antenna, this kind of method is suitable for the transmission bandwidth requirement is not high, the distance is near;

The advantages of this method are that the transmission distance is far, the signal is strong, the bandwidth and the transmission quality are guaranteed. (determined by customer needs and circumstances).

(3): A point, B point is not seen between, but the distance between the two, only a few kilometers, and there are many buildings between the two. According to the actual situation, the signal reflection scheme can be used to interconnect a point B. AB Point, respectively, the wireless network Bridge, directional antenna, wireless network Bridge settings. The microwave signal transmitted by a directional antenna A is communicated with the directional antenna B after being reflected by the CD two buildings.

Wireless network Bridge for those who need to expand the existing Ethernet network coverage and system capacity of network managers, more than the traditional wiring to achieve the solution. Wireless network Bridge can expand existing Ethernet, connect with high-performance wireless network. It is flexible enough to meet your requirements. Especially in today's changing office environment, it can greatly improve the efficiency of work.

The wireless bridge extends the range of your wired Ethernet network, providing easy access to mobile end users and difficult cabling areas. The special structure, superior performance and dual PCMCIA sockets give the following advantages:

Secure your investment The dual PCMCIA socket provides an unobstructed way to move to future wireless network technologies (including local area network standard IEEE802.11) to ensure your investment in other WaveLAN products.

Double network capacity You can use two PCMCIA network cards at the same time, and use each frequency.

Wireless backbone can be established in the open areas of large warehouses and retail stores, you can use the wireless bridge as a bridge to connect to the wireless subnet, eliminating the hassle and expense of rewiring the line.

Wireless Bridge is a member of the WaveLAN product family and can be managed by Wavemanager/accesspoint software.

Low-cost network management is based on windows and conforms to Simple Network Management Protocol (SNMP) wavemanager/access Point Software, making it convenient for you to set the parameters of the wireless Network Bridge. With this software, you can centrally manage, control, and remotely monitor your network.

Controlling unauthorized access WaveLAN's product line provides you with 4 security measures: Direct sequence modulation spread spectrum transmission technology, NWID, access control, DES or AES data encryption.

Product Application

Typical uses for wireless bridge include:

Internet access, temporary installation, or conference room environment;

Open space but cannot use the cable way, such as exhibition, historical building, etc.;

Inter-building network interconnection, disaster recovery, backup;

Warehousing and port management, hospitals, airports and so on.

The role of the wireless network Bridge, it can be used to connect two or more independent network segments, these independent network segments are usually located in different buildings, hundreds of meters to dozens of kilometers apart. Therefore, it can be widely used in the interconnection between different buildings. At the same time, according to the Protocol, the wireless network Bridge can be divided into 2.4GHz band 802.11b or 802.11G as well as the use of 5.8GHZ band 802.11A Wireless Network Bridge. Wireless Network Bridge has three ways to work, point-to-point, point-to-point, relay connection. It is especially suitable for long-distance communication in cities.

In the absence of high barriers (peaks or buildings) under the conditions of a pair of speed network and Field operation of the temporary network. The effect distance depends on the environment and the antenna, now 7km point-to-point microwave interconnection. A pair of 27dbi directional antennas can realize 10km point-to-point microwave interconnection. The 12dbi directional antenna can realize 2km point-to-point microwave interconnection; a pair of wireless network bridge that only realizes the function of link layer is transparent bridge, and the device with network layer function such as routing, and network 24dbi directional antenna can realize heterogeneous network interconnect is called wireless router, also can be used as the third Layer Network Bridge.

Wireless network bridge is usually used for outdoor, mainly used to connect two networks, the use of wireless network Bridge is not possible to use only one, must be more than two, and the AP can be used alone. Wireless network bridge Power, transmission distance (maximum up to about 50km), anti-interference ability, and so on, not with the antenna, generally equipped with parabolic antenna to achieve long-distance point-to-point connection.
