Build a multi-tiered wireless network to unify network access

Today more and more products to join wireless this huge family, notebooks, mobile phones, cameras, projectors and other equipment become a daily essential office and communication equipment, but also by virtue of the characteristics of strong mobility, so that many people more dependent on wireless internet. Now the use of wireless network is not limited to one floor, many office buildings, luxury hotels, large shopping malls and individual villas are urgently needed to achieve a unified wireless network access solutions.

In addition, the use of wireless networks is becoming one of the ways in which some small and medium enterprises use the information exchange. However, erecting a set of multi-layer wireless devices is not as we imagine, buy some equipment assembled so simple, which contains many of the many factors before the formation of Multi-layer Wireless LAN, including: Office wireless signal coverage, the establishment of wireless network security, the compatibility of wireless equipment and so on. Today we will talk to the office on how to achieve a multi-level wireless network environment of the topic to communicate with you.

How to achieve the formation of multi-layer wireless network, we must mention the following: equipment selection, control costs, post maintenance.

1. Equipment selection

The equipment includes the brand, the price, the performance, the localization many factors, here we like everybody Brief introduction. At present, the main wireless router brand has a network, Belkin, D-link, Tp-link, Buffalo, H3C and other brands, high-end and Cisco. Prices from hundreds of yuan to thousands of yuan, we recommend that the Enterprise users choose the brand for enterprise users to launch products. For product performance, Based on 802.11g wireless router products are currently a good choice, because the product is not mature based on 802.11n, from the previous test to see the compatibility of each product is also different, the other client's network card can not guarantee the unification, and the wireless router based on 802.11n and network card prices are very expensive. The choice of equipment does not necessarily look at the brand, as long as the application of their own business needs of the good.

2. Cost control

For an enterprise how to control the cost of investment, and get a good return on investment is more important to each boss. The choice of equipment should be in advance according to their actual environment to choose the product category and quantity. such as: a more decentralized office area, more obstacles to the office environment, we should choose a strong signal penetration of the router.

3. Post-Maintenance

In the selection of good products, users also need to consider the product after-sales service and other factors, such as the failure of the above services, firmware timely upgrade, and even to consider the entire network after the attack recoverability and recovery time.

This is not only a network of unified management needs, but also to reduce costs should be the meaning. The different floors share a network interface through the main trunk line, each floor uses several AP to realize the wireless network access respectively.

1, the same floor to deploy a number of AP (depending on the size of the AP), the AP through the cable access backbone network.

2, the floor between the use of wired backbone connections to ensure network stability.

3, if the horizontal direction span is big, need to increase the AP but inconvenient wired connection backbone network, may through bridge connection

Here's how to set up wireless APs:

1, "Network parameters". Set different IP addresses to each AP to avoid network address conflicts.

2, "Wireless Parameters"-"Basic settings." Set the SSID of each AP to be the same, which is guaranteed to connect to the same wireless network.

3, "Wireless Parameters"-"Basic settings." The AP sets up the different frequency bands, and it is more than 5 bands apart to avoid interference between them.

4, "Wireless parameters"-"Security settings." The AP sets the same encryption authentication method and password.

Deployment tips:

1, by adjusting the position of AP and adjusting the transmitting power of AP, the coverage area of adjacent AP can overlap properly, and the blind zone is reduced.

2, can use PASSIVEPOE power supply, increase access to the AP display flexibility to achieve better wireless coverage effect.

The purpose of this paper is to discuss the establishment of multi-storey wireless network. It is well known that the performance of wireless networks will be greatly affected when obstacles or other wireless signals are disturbed, and the network topology described in this paper is only for the application of typical environments. In the implementation of the wireless network planning and the establishment of the time, need to conduct field visits to test the wireless signal and throughput, so as to choose the appropriate number of AP to meet the actual application requirements.
