- Enterprise WLAN needs analysis
With the rise of smart mobile devices, BYOD to the popularity of the company's high-quality WLAN has become the stringent requirements of the company's mobile office.
In a specific application process, comprising the WLAN's specific requirements:
WIFI secure access to enterprise 1.1
With the development of enterprise information construction projects and national information, the information office of the progressive realization of the company, increasing the demand for BYOD. More and more companies use the wireless network to access their internal business systems and office. Subject to limitations affect the wireless network, security issues have become increasingly prominent, the urgent need to secure access mechanisms to protect the customer service system ***.
1.2 enterprise security office WIFI
Expanding the company's business, the company is dependent on the network traffic is increasing. Wireless network technology matures, many enterprises to expand the deployment of their daily work and business consulting and customer reception of the wireless network. Office, visitors, conference rooms and other wireless networks need very popular by the time the intelligent terminals, wireless networks can also allow tablet computers, mobile phones and laptop computers become office tools. Security is accompanied not only in the Internet, how to protect network security company after the visit, and to ensure the normal operation of enterprise systems, the need for effective solutions to double wireless security.
1.3 WIFI fast internet business
As the company continues to develop, the business needs of wireless networks is also increasing. However, since the wireless network has no borders, and the fact that the signal susceptible to interference, the wireless network may experience connection unstable, the process of slow Internet access and insufficient bandwidth applications used in multi-user. Therefore, the effective use of corporate email, finance, office software, Internet business systems, information and reviews of tourists need fast wireless networking support.
Enterprise 1.4 WIFI fast roaming
With the development of smart mobile devices, BYOD presents business trend. In order to achieve BYOD anywhere in the company, we must ensure perfect coverage, fast roaming and high signal quality of the wireless signal.
A plurality of access terminals, a plurality of positions to ensure good integration access, control and management.
1.5 Enterprise Internet behavior management

1.8 enterprise data protection, security
Enterprise business system as a kernel data, wireless networks have different wired network. All data on the wireless network are transmitted wirelessly, we need an efficient and highly secure encryption mechanisms to ensure that data is not stolen or leaked and reveal company secrets.
Wireless implemented as a wired extension limit and how to protect network access is more difficult than 0x7D0 and security issues, such as to control the wireless internet connection for employees, but also a lack of good management tool. Several fishing AP and AD- hepatic oval cells can be hidden in a wireless environment, data transfer, the risk of the virus in the data everywhere, and the need to protect and ensure data security and business.

In some wireless bandwidth, staff run a large number of P2P downloads, video display applications, high bandwidth consuming bandwidth, powerful standard system to seize, resulting in bandwidth consumption business resources, low efficiency and wireless office processing business.
2.5 *** various means of wireless, network security threat
Different network based on the physical ports for wired security defense. Because of its own characteristics, anyone can see the wireless signal coverage area. For companies, there are security threats such as theft and illegal account access, etc. is inevitable.
2.6 multi-air garbage, wireless access stability can not be guaranteed
2.4GHz band used by WiFi network mostly known, the 2.4GHz band is unlicensed band, working in this band a lot of equipment, such as: microwave ovens, Bluetooth, wireless landline, foreign NAP, surveillance cameras, etc., WiFi devices will be a lot of interference. In addition, non-interfering channel 2.4GHz with only 1,6,11, When deployed to a region occupied by the operator is the AP, not much available channels. In this case, delay and packet loss will cause interference, the actual transmission rate is often not guaranteed.
