The strongest ADSL Access Solution in history

With the development of the communication industry, there are more and more market demands. It is necessary to design a reasonable ADSL Access Solution for users so that users can use it more conveniently and quickly. With the maturity of the broadband technology and the decrease of the market application threshold, the ADSL Broadband business has gradually gained the recognition of market applications. In some service fields, such as hotels, airports, large conference rooms, and restaurants, the degree of business intelligence is regarded as the criteria for evaluating service quality. Therefore, how can we effectively combine broadband and wireless networks, in this way, service levels can be improved to meet the increasing needs of mobile office services. Similarly, in the construction of networks in some industries, such as campus networks, even if the construction of various broadband private networks is complete, it is also faced with the problem of how to satisfy the mobile teaching network business.
At present, although the business needs vary in these fields, the application environment has the following characteristics:

First, the business flow is large, the crowd flow is frequent, the access method is required to be flexible, and the quality of the network is high. Second, as a supplement to the wired network, the establishment of the wireless network, consider the original network facilities, save costs as much as possible, optimize the network structure, and establish an economic access mode. Based on the above factors, D-Link designs two sets of wireless ADSL access solutions based on the actual situation of urban hotspots and campus networks, different user groups can enjoy "free broadband" wireless networks.

1. ADSL Access Solution in urban hotspot areas

ADSL Access Solution in urban hotspot areas
This solution is designed for public places such as hotels, airports, large conference rooms, and restaurants. In these places, users with high traffic and Internet access needs are generally business users who need to stay for a short time and have mobile PCs, laptops, handheld computers, and other mobile office equipment. Taking these factors into account, the flexible wireless access method is adopted in the solution, and DSL-604 + wireless ADSL Router is selected as the wireless broadband interface, and the telephone line is connected to the Internet network. In terms of coverage, a DSL-604 + indoor wireless coverage of up to 100 meters, outdoor width can be up to 400 meters, the user can be based on the actual application needs, determine the number of installation. The lower-end mobile users can easily achieve wireless Internet access by configuring the corresponding wireless network card. In the solution, D-Link provides three optional NICs: DWL-650 +, DWL-120 +, and DWL-660W.

The main features of this solution are: the unique 22 m wireless access can better meet the bandwidth requirements of users; supports a variety of wireless access terminal products; built-in DHCP and NAT, reducing the cost of network construction for Small and Medium LAN; DSL-604 + Built-in firewall function, to ensure the security of the local area network; the use of pre-payment card billing method, payment and Internet access is simple, account unified.

2. Campus ADSL Access Solution

Campus ADSL Access Solution
The above design is mainly designed for the actual situation of the school. This solution can be applied to the network environment with ADSL Broadband. In general, there are Internet access needs in the school library, step-level classrooms, and dormitories. However, the network needs and environments in each place are different. Under normal circumstances, the library and dormitory fixed terminal and mobile device coexist, so the scheme adopts the wired and wireless coexistence design; In the tiered classroom, there is usually no fixed terminal, thus, a wireless network architecture is adopted. From the figure, we can see that the entire network egress, using D-Link DSL-604 + wireless ADSL Router as the wireless access device. This product uses a physical design that combines wired ports and wireless interfaces, so that the network can support wireless connections from various terminal devices. Similarly, in the solution, D-Link provides two optional NICs: DWL-650 + and DWL-120 +, users can choose as needed. The main features of this solution are: large business traffic and fixed service locations, which can achieve economic access mode and secure network management. Two billing methods are available: monthly subscription and prepaid cards.
