Technologies and indicators of wireless network products
1. device Selection
The device contains many factors such as brand, price, performance, and positioning. Here we will give you a brief introduction. Currently, the main brands of wireless routers include network devices, Belkin, D-Link, TP-Link, Buffalo, H3C, and Cisco. The price also ranges from several hundred yuan to several thousand yuan. It is recommended that enterprise users choose products launched by various brands for enterprise users.
In terms of product performance, 802.11g-based wireless router products are currently a good choice, because 802.11n-based products are not yet mature, and the compatibility of each product is also different from previous tests, in addition, the network card of the client cannot be unified, and the price of the 802.11n-based wireless router and network card is very expensive. Choosing a device doesn't necessarily only look at the brand, as long as it suits your enterprise's application needs.
2. Control Costs
For an enterprise, how to control investment costs and get a good Roi is a matter of great importance to every boss. When selecting a device, you should select the product type and quantity according to your actual environment in advance. For example, if an office area is scattered and there are many obstacles in the office environment, we should select a router with strong signal penetration capability.
3. Post-Maintenance
After selecting a product, the user also needs to consider factors such as after-sales service of the product, such as the service and firmware upgrade after the fault occurs, it is even necessary to consider the recoverability and recovery time of the entire network after the attack.
Recommendation of Wireless LAN Solutions in three wireless network environments
After briefly introducing the technologies and indicators of wireless products, we will introduce some applications of the three types of wireless products in the actual environment. Wireless products usually work in the following states based on different application scenarios:
1. AP Wireless Access Point signal coverage mode) and AP Client wireless Client mode ).
2. The Bridge Mode of the WDS Wireless Distributed System) and the AP + WDS hybrid mode both bridge and overwrite ).
3.802.1x authentication and seamless client roaming.
802.1x Authentication and seamless client roaming are suitable for large enterprises, airports, bars, hotels, and other public places. In this way, high-density, high-speed wireless access, mobile Internet roaming, 802.1x authentication, and billing can be achieved. We recommend that you ask the device manufacturer to make a good design plan and budget before using the service. You may also want to refer to several successful cases. At that time, we believe it will be helpful for your enterprise's wireless network solution construction.
In recent years, more and more products have been added to the wireless family. Laptops, mobile phones, cameras, projectors, and other devices have become one of the indispensable office and communication devices. We often see some SOHO users who are using laptops to wirelessly access the Internet at the entrance of the cafe, and business users who use PDA to download emails. It is precisely because of its high mobility that many people rely more on wireless Internet access.
In addition, the use of wireless networks is also one of the information exchange methods used by small and medium-sized enterprises. However, setting up an office wireless device is not as simple as we think. Buying some equipment is just as simple as assembling it. It contains many factors before the establishment of the office LAN, the main problems include the coverage of office wireless signals, the security of wireless networks, and the compatibility of wireless devices. Today, we will discuss with you how to implement the wireless network environment in the office.
Wireless Network disadvantage Analysis
Just now we have talked about the advantages of using wireless networks. Below we will also talk about some of its shortcomings. First, the signal coverage of wireless networks is one of the factors we need to consider. When it comes to signal coverage, we should first look at its transmission protocol. Common wireless network protocols include IEEE 802.11, IEEE 802.11a, IEEE 802.11b, IEEE 802.11g, and the draft standard 802.11n.
Coverage of wireless signals
Although IEEE 802.11 \ 802.11a has been eliminated by new standards, it is undeniable that the first wireless LAN standard proposed by the Institute of Electrical and Electronics Engineers in 1997 is a milestone in the development of IEEE 802.11 wireless network technology.
Wireless Networks are widely used in office environments. People are becoming increasingly mobile and increasingly dependent on wireless networks. Therefore, the above analysis hopes to serve as a reference for companies or enterprises that are about to build wireless networks.
