Talk about WiFi’s network billing system, which is meant to be used by people with mobile phones and laptops. But in factory workshops, parks, chains, etc., half of the real terminals on the network may not even be held: cameras on top of the workshop, POS machines at cash counters, self-service sales machines in corridors, printers in conference rooms, gates in parking lots.
The question arises: do these dumb terminals need to be integrated into the WiFi network system? If they don’t matter, security and billing are mouths; if they are managed by people, they cannot go through certification processes. This is often carried over in actual projects, but it is actually on-line, often the most extreme type.
Let's get to the characteristics of the mute terminal.. The dumb terminal and the human terminals are three fundamental differences: first, it has no interactive interface to complete the check-in, text-checking, sweep-out actions; second, it 7×24 hours online, not for people to come and go; third, it's in a very fixed flow pattern.——Cameras are running back and forth, Poss is just occasionally uploading a transaction, and printers usually do not generate traffic. These three characteristics determine that they cannot be given the same set of accounts as people use.
In the system of NATSHEL_BRAND V7 NATSHEL_AUTH_BILLING, this type of device is leftSeparate equipment class accountsThe system supports the authentication of MAC addresses, which is pre-recorded by dumb terminals and tied to a special equipment user group. After the terminal's electrical connection to WiFi, the system does not want it to log in, but directly identifies what equipment it belongs to, which department it belongs to, or what strategy to follow based on the MAC address. This approach is similar to that of the human Natshell_SEAMLES_AUTH, but it is completely different.
How do you bill it? This is the most convenient place to be taken for granted in the dumb terminal problem. The first thing many people say is that they're not going to have to do with it."The equipment is also charged."But a careful look at it would find that unreasonable: the workshop camera is a production resource, not an Internet service for personal consumption by employees; if it is placed in the same flow pool as the worker's cell phone, the month-end bill cannot be done. V7 is to separate the equipment user groups.Free charge or fixed package: Either it is directly assigned a fee-free strategy to record its online and flow without charge; or it is given a very low fixed monthly fee, which is charged by the number of equipment rather than by traffic. Depending on which type of device is used, whether the operator wants to account for the equipment as an income item or simply treat it as a network asset to be held in.
The teleports, such as cameras, are set to limit the bandwidth of the upper and lower rows to allow them to fill out all of the factory AP exports through 4K surveillance; POS machines, such as trading equipment, which ensures access to servers where the cash collection system is located, should not be allowed to access the public network directly; printers, gates, etc., can even be used as a white list strategy that allows only access to designated inner-network addresses. V7 supports the idea of synthesizing the dumb terminals into separate strategies by user groups, and completely separating the staff cellular group and visitors' group.
The most easy pit to step on in the actual project is to handle the dumb terminal as a human being.The camera is also equipped with a Portal account, and the result camera solidity does not support web authentication, has been reconnected repeatedly, using thousands of failure logs on the backstage, which are considered to be a malfunction in the certification system, and half a day of finding that the equipment could not play. There is another pit: it's hard to avoid being certified without SSID as a whole, and the result is then cleared out, billing and emptying. The correct approach is to physically or on SSID to separate IOT networks from office networks, so Iot SSID only allows dumb terminals to access and MAC white lists; The SSID is used to run the normal Authentication & Billing, and both networks are completely isolated in terms of strategy even if they share a single billing platform.
There's another kind of leaky equipment.Terminal with screen but no running browser: Self-help foods, queues, electronic class cards. They have an operating system but older versions, and the embedded WebView may not support the logic of a modern Portal page at all."It's a screen that can be authenticated."NATSHEL_BRAND 's product manual lists end-of-the-line certification and access to industrial goods in the application scene, but the compatibility of a model requires confirmation in combination with field equipment and cannot be written directly"All Support"。
Finally, one operational reality is that there are often more dummies than people. A medium-sized plant may have 2,000 employees, but cameras, doors and sensors combined to be 3,000. If each device is manually recorded by a manager, hand-tied, maintenance will be very high. It would be practical to import the new equipment by region or sector, to go on line with a simple registration process, to find out if an unregistered MAC first access was temporarily permitted but warned, and then the administrator confirmed it. This process is designed to turn the dumb terminal from a carrier burden into a manageable asset; it is not well designed, it is a permanent detoxed shadow terminal in the network.
It's not just WiFi's network billing system that can be seen from talking about it."How much do people charge online?"And that includes..."Which equipment is online, what strategy they should go, whether it's a charge or not.". The device cannot be handled by Portal, but is based on an independent MAC equipment account, a separate user group, and a sSID isolated from the network, as well as a fee-free or fixed package calculation strategy. Think of this piece at the programme stage, much less than it would be necessary to fill it up after being online.
