Day-Feed coverage scheme

Day-feed coverage, as the name implies is the use of AP, feeder, plus ceiling antenna to build wireless network. thereby reducing the use of APS to reduce the interference of the same frequency.

Working principle:

Day-feed coverage using APS are high-power industrial wireless APs, power is the general home wireless router 7-8 times, is the general ceiling-type AP 5-6 times, high-power is to ensure the basic coverage effect. The greater the power, the better the penetration effect. The feeder is a copper core line, which avoids the problem of severe attenuation of the signal during transmission. Ceiling antenna for passive parts, that does not require power to operate, so that the ceiling antenna is not easy to damage, aging speed is relatively slow, the biggest feature is the ceiling antenna is only used to transmit the signal of AP, will not occupy the additional channel, an AP regardless of the AP external 2 or 4 ceiling antennas, will not occupy the additional channel, The same frequency interference is completely avoided. Day-feed coverage scheme, generally an industrial-grade wireless AP External 2-4 ceiling antenna, covering 16-24 rooms. For example, in the middle corridor, the rooms on both sides of the hotel, the equipment installed in the corridor, the signal through the walls of both sides covered in the room. The use of a day-feed scheme, can be very good to avoid the same frequency interference.

Role:

Day-fed coverage is generally used in hotels, guesthouses, office buildings, these rooms are more than the number of people on the Internet more than the environment. Because the hotel, hotel and other network terminal use is mobile phone, tablet, so the traditional wired network coverage has little meaning and gradually replaced by wireless network lock. And for the hotel wireless coverage of the scheme and equipment, such as ceiling-mounted or panel-type coverage , each AP will occupy a channel, 2.4G wireless WiFi really does not interfere with only 1, 6, 11 of these 3 channels, AP channel repetition will produce the same frequency interference, affect the stability of the wireless connection. Simply said 2.4G Wireless WiFi band is too crowded, easy to co-frequency interference. and the same frequency interference is the problem of the AP community, the day-fed coverage is the same area with the environment, the use of equipment in the machine program is the least and the maximum elimination of the same frequency interference, has been widely used.

Day-feed coverage scheme:

AP and ceiling antenna installed in the corridor, the construction is simple, the wireless signal through the corridor on both sides of the room, not to each room for construction, but also to avoid equipment installed in the room easily damaged. The whole scheme has fewer equipments, less fault points, stable operation and no maintenance after installation and commissioning.

Placed on each floor a set of wireless APs, wireless APs via Poe Power in the computer room connected, wireless AP through the feeder connection ceiling antenna installed in the corridor, each antenna 10-20 meters apart, each antenna covering 6-10 rooms, 2-4 suction ceiling line can cover 16-24 rooms.

Its characteristics are: simple installation, low cost, can effectively avoid the same frequency interference.

Success Stories:

The early general is to move, Unicom and other communications companies for indoor-based, very few engineers use, after the mobile, unicom over the years covered the technology of maturity and coverage of the test, the day-feed coverage program has been widely promoted. Now there are many engineers to use the day-feed coverage scheme for hotel hotels to do network coverage, coverage effect has been the hotel and residents of the identity.

For example: Guangdong province Guangzhou Baiyun District Huangshi Street CongYun Lubehau Hotel, Guangxi Guilin Xiangshan District International Hotel, Harbin Commercial University, Harbin City, Heilongjiang province, Liaoning province Shenyang Kangping County Jin Xiang Business hotel, Shandong province Qingdao Shibei District Taiwan KTV and other hotels, guesthouses, student dormitories, KTV has been successfully used in the day-feed coverage scheme for network coverage.

Features of the antenna-fed coverage scheme:

1 , suitable for all hotels and old hotel renovation, equipment installation fast, maintenance simple, easy to expand.

2 , installed in the corridor, It is not necessary to carry out the construction of each room, but also avoid the equipment installed in the room easily damaged.

3 , the whole scheme of equipment, fewer points of failure, stable operation, installation and commissioning after the year without maintenance.

4 , support WAP2 key, with enterprise-class routing server for authentication management and traffic control.

5 , using a small number of APS, each layer of AP set different channels to avoid the same frequency interference, wireless connection stability.

6 , low cost of equipment, high coverage efficiency, no blind spots and dead ends of the signal, small radiation does not affect health.
