Most people do not understand the knowledge points of this article "what are the common enterprise-level WiFi building programs?", so the editor summarizes the following contents, detailed contents, clear steps, and has a certain reference value. I hope you can get something after reading this article. Let's take a look at this "what are the common enterprise-level WiFi building programs?"

Option 1: only router or AP coverage

Summary: use a router or AP to cover multiple wireless blind spots, and the deployment of multiple AP to achieve the coverage of the whole area.

Suitable for users: small offices, catering in small areas, etc. (the "small" here only covers a small area and has few users).

Advantages:

The cost of equipment is the lowest, the price of a home wireless router is about 100 yuan, and the price of an ordinary wireless AP is only about 300 yuan. Disadvantages:

The coverage effect is poor, and there are many blind areas, so it is necessary to increase the number of wireless access devices. The wireless access of a single device is about 10 users, which can not meet the access needs of a large number of users. The more the number of wireless access devices, the easier it is to cause wireless interference between wireless access devices. The electricity must be taken nearby and installed inside the ceiling is inconvenient for maintenance, which has a great impact on the signal; the installation on the outside also affects the appearance. Management is not convenient, it is necessary to manually set up each wireless access device and put it on record, it is difficult to plan, and it is impossible to troubleshoot in time when there is a fault. When the wireless access equipment fails and needs to be restarted, it must be powered off and restarted at its installation location, which is inefficient. The reliability of the equipment is poor and the performance is low. Comments:

This kind of wireless coverage networking mode is only suitable for small offices without management. For enterprises or hotels, such a plan is tantamount to not doing, it is deceiving yourself.

In such a case, when a hotel had more than 100 rooms, China Unicom gave away more than 100 routers when applying for optical fiber, so the hotel placed a router in each room. Since then, the engineering department has revolved around these routers almost every day. More than 100 routers, even if you manage them alone, you have a big head!

Scheme 2: AP+AC (thin AP+ wireless controller)

Suitable for users: high-density user access, seamless roaming, complex wireless environment (multiple AP deployments in the region) and other user environments.

Advantages:

Fit AP is generally designed for enterprise applications, and its hardware processing capacity is powerful. Generally, the maximum standby user of a single AP is 20-30. The equipment has good reliability and high performance. AP can be easily managed through AC. Equipment generally supports POE power supply, management, security and convenience. You can choose enterprise-class wireless access authentication equipment to provide high-level stepless security. It can automatically adjust the wireless transmission power and reduce the wireless interference between devices. Disadvantages:

The price of a single AP is generally more than one thousand yuan-several thousand yuan. AC is priced based on user authorization (the number of AP managed by each AC). Product debugging is professional and needs to be maintained by professional and technical personnel. Comments:

Thin AP+AC coverage scheme has obvious advantages in large-scale enterprise networks. perfect management, load, automatic power, channel and so on provide a stable network environment for enterprises. However, due to the high cost of products, the most important is AC, which is basically more than 2W, so small enterprises generally use less, which is suitable for large enterprises, such as Hanting hotel chain to force the use of Cisco thin AP+ controller for a kind of urban franchise stores.

Option 3: WOC scheme (WLAN Over Cable)

The cable network transmits wireless signals to each guest room without rewiring, replacing the original TV signal sharer and guest room cable TV panel, and then connecting to the wireless AP.

Applicable users: community operation, hotel industry

Advantages:

Every room has a good signal and there is no blind spot. Each guest room has low wireless transmission power and eliminates wireless interference between equipment. The wireless signal is stable and the Internet access effect is good. Wireless AP is free to choose. Disadvantages:

The cost of the project is high, and the equipment needs to use high-power carrier-grade equipment, and the WOC panel needs to be replaced in each room. The quality of the original limited line is required to be high. At present, the general limited network wiring structure of domestic completed hotels is not standard and the line quality is not standard, so the practical application effect is far from the theory. Comments:

In the infrastructure of the hotel, cable TV network is more important than wifi. With the help of the cable TV network equipped with wifi coverage, resulting in the hidden trouble of cable TV, so it is basically covered by the corridor layout of AP.

Scheme 4: wireless coverage of antenna and feed system (distributed antenna)-- the mainstream scheme adopted by telecom and mobile at present.

Each AP connects multiple antennas through a feeder, and the antennas are arranged in the coverage area to achieve large-scale coverage of a single AP.

Suitable for users: public areas, hotels, a wide range of low-density environment.

Large area Wireless WiFi coverage built in Wireless WiFi Environment of Scenic spot

Advantages:

Multiple areas can be covered by a single AP. (high-power equipment can connect up to 12-20 antennas when feeder attenuation allows.) There are no interference and roaming problems between the coverage areas of antennas connected to a single AP. The signal effect is good, and the channel is easy to plan. AP antenna feed system has a wide range of choices. Disadvantages:

The cost is higher, and the cost of accessories related to the antenna feed system is higher. The process requirements are high, and the production of the joints installed in the antenna feed system requires high process requirements. The effect of making (manual) on signal attenuation is very obvious. The antenna and feeder system needs to be wired. Comments:

Many medium-sized brand hotel chains use this approach, and the coverage effect is very good, and each coverage area is full of signals. However, this scheme also has its own shortcomings.

Because the same device covers multiple areas through multiple antennas, all the traffic and load in these coverage areas are through a single AP, which requires high performance of AP. When designing the scheme, we should not only consider the signal and coverage, but also consider the maximum number of users in the area. Secondly, 802.11g networking is generally used, because the core of 802.11n technology is MIMO antenna, that is, antenna array. In the network with antenna-fed scheme. General use of ordinary antennas, single feeder way. Of course, in theory, three groups of feeders and MIMO antennas can be used to achieve MIMO access, but the cost is high.

Scheme 5: embedded AP wireless WiFi coverage

This scheme can be said to be an extension of the lean scheme (AP+AC). The thin AP scheme mentioned earlier in this article refers to the traditional AP. Embedded AP (86 AP, wall-in-the-wall AP) is the latest product, which adopts the wireless access point designed with standard 86 bottom box size. Can be installed directly in the 86 bottom box. Embedded in the wall.

Applicable user: hotel

Advantages:

The construction is simple, there is no need for rewiring, only the existing panel needs to be replaced. The centralized management of multiple AP is realized through the controller (soft / hard AC). Using POE power supply, safe and easy to manage. Disadvantages:

It is not suitable for high-density user access. Generally speaking, the processing capacity of a single AP is 10-15 users. Users have limitations, basically only suitable for hotels, apartments and other project environment. Among the brands currently in contact with. The coverage effect of different brands is very large, which may be caused by the manufacturer's different positioning of this product. Comments:

The in-wall wireless coverage scheme first appeared in the second half of 2012, when it was mostly fat AP, that is, devices that could not be managed centrally, making it very difficult to manage when multiple AP were deployed. Since 2013. Mainstream manufacturers including H3C have launched centrally managed and fit-based devices. This plan has just been perfected.

For example, for a hotel, if an AP is placed in the corridor, the signal needs to penetrate the entry bathroom. The coverage effect of a single AP is not good, and the coverage area is small. The Tianfei scheme requires a lot of construction for hotels in operation. So there are limitations. The solution of wall-to-wall AP avoids these problems very well. Just install POE in the weak power room. Change the panel in the room.

In the actual network scheme, it is often to integrate the advantages and disadvantages of each scheme, as well as the actual needs of users to adopt a flexible configuration combination, which has reached the final application requirements.
