The WiFi deployments are often much more complex than they appear. Public areas, merchant areas, employee areas, VIP rooms, and the use of networks vary from one region to another, as well as user identification.WiFi web certification systemThe zonal strategy is the most important part of the large market network project that needs to be thought out in advance.
Classification of the user groups for business scenes
The WiFi users in the mall are roughly divided into: general customers, shop employees, mall managers, outside construction workers, and VIP members.
The main demand for regular customers is to brush their phones, send out a circle of friends, watch videos. They don’t need high bandwidth, but they are many, and the entire shop will be filled with bandwidth soon if not limited.
Business people need a POS machine, a cashier system, and an inventory management system that is sensitive to network delays and requires high stability but does not require large bandwidth. They need independent authentication accounts that do not use the same network as their customers, otherwise they have a problem with the volatility of customer traffic.
Business managers (security, cleaning, property) need to use the internal system of the mall, such as video surveillance, broadcasting, emergency command.WiFi web certification systemis the corresponding permission configuration.
SSIID design and area isolation
SSID is designed to underpin the strategy for partitioning. Different user groups use SSIDs for access, and each SSID corresponds to different authentication strategies and network strategies, which are the clearest way of segregation. Typical design:
Public customer SSID: Open Access, Portal Page Certification, with bandwidth ceilings, content filtering strategies (defendance), and time limits for access to the Internet (e.g. 2 hours per authentication, overtime is required).
SSID: Account code authentication or WPA2-Enterprise, no bandwidth restrictions, no content filtering, higher priority than customer flow, independent certification account numbers for each household and specific store number binding.
SSID: The inner network is independent, not using a public certified server, and the management equipment is tied directly to the inside network and is not connected to the net.
SSID design takes care of one principle: do not take SSIDs too thinly. The more it appears to be detailed, the more it is managed, the more its wireless resources are used, the more impact on overall network performance is the greater. It is generally recommended that no more than four SSIDs be broadcast by individual APs.
Design of a flow management strategy
Several common design ideas:
Single user speed limit: each authentication account limits a maximum up/down bandwidth limit to prevent individual users from occupying the bandwidth. This is the most basic flow management, basically allWiFi web certification systemBoth support. Speed limit values are based on actual bandwidth resources and the number of users expected, not as small as possible——The small speed limit makes users feel that the network is too poor.
Regional master bandwidth limits: The WiFi total bandwidth in a public area is capped, and new users are certified successfully after reaching the ceiling but the speed of the net decreases. This design ensures that business bandwidth is not absorbed by customer traffic, but requires network equipment to support regional-level traffic control, not all AP or AACs can do so.
Dynamic adjustment of peak periods: weekends and holidays have several times the flow of people over normal days, allowing for a peak time strategy to be configured in the certification system——The speed of peak list users is more stringent and the low peaks are relaxed. This dynamic adjustment requires a time-frame strategy supported by certification systems, which can be automatically switched without manual intervention.
Specific challenges in managing business accounts
The large malls usually have hundreds of businesses, and there is a high turnover of traders, with each shop likely to leave and enter the workforce for one or two months."The staff left but the account number is still there."Security danger.
It's reasonable to have one for each business."Businessman"Permissions——Each business has a management account that allows itself to manage the shop’s employee accounts on the self-service portal, and it does not require any change or reduction of employees through the mall IT.WiFi web certification systemThe authority to support the account is graded and tenants are segregated.
Special treatment during major events
The certification system needs to be able to respond to more than 10 times the normal time for simultaneous requests for certification, while also matching marketing requirements such as jumping to the event page after a customer has completed the certification.
Advance capacity preparedness is critical, including the expansion of authentication server resources (in the case of cloud deployments, early build-up; in the case of local deployments, confirmation of hardware surplus), confirmation of SMS gateway dispatch caps (the volume of text messaging during major events may exceed a single service provider's limit) and consideration of activity-related ad hoc content replacement options on Portal page design.
The Portal page changes during the event will require a fast-distribution process that allows for rapid switching to the activity version before the event starts, quick recovery of the regular version after the event, and operation by the market ' s own IT team without relying on engineering cooperation.
The WiFi zoning and flow management of the business scene is a process that requires conceiving business needs at the design stage of the technical programme. It would be prudent to identify these requirements at the bidding documents and evaluation stage if it were to be completed, if it was found that the scheme did not take account of the classification of households or that the zonal particle size was inadequate, and the cost of readjustments would be high and could affect normal business operations.
