Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, below in conjunction with accompanying drawing the embodiments of the present invention are explained in detail.Yet, persons of ordinary skill in the art may appreciate that in each execution mode of the present invention, in order to make the reader understand the application better many ins and outs have been proposed.But, even without these ins and outs with based on many variations and the modification of following each execution mode, also can realize each claim of the application technical scheme required for protection.
The first execution mode of the present invention relates to the wireless access points equipment installation method in a kind of WIFI network, and idiographic flow as shown in Figure 2.
In step 210, according to the type of the type selecting wireless access points AP equipment of application scenarios.It will be understood by those skilled in the art that application scenarios can be divided into indoor, outdoor two large classes, in the present embodiment, describes as an example of indoor application scenarios type example.Therefore, the type of AP equipment comprises indoor distribution type AP equipment and the indoor dress type AP equipment of putting.Indoor distribution type AP equipment can be H3CGNP series radio reception device, this products characteristics is: defer to the 802.11n consensus standard, wireless transmission rate and the complete machine gigabit access capability of space 3 stream (3-Streams) 450Mbps can be provided, about 10 times of 802.11a/g product under the equivalent environment, by built-in integrated terminal sensing type hardware smart antenna soverlay technique, can be effectively from coverage, access density, the aspect such as stable provides more high performance mobile cloud access service and assisting users to realize optimal wireless network TCO (TCO/Total Cost of Ownership); The indoor dress type AP equipment of putting can be H3C WA3600i series radio reception device, and this products characteristics is: defer to the 802.11n consensus standard, maximum transmission power can reach 500mW.Using the distributed road of closing when disposing, can the indoor distributed road system of closing of compatible original operator, flexible, radio-frequency channel, every road can provide the wireless access rate up to 150Mbps, is about 2 ~ 4 times of 802.11b/g product under the equivalent environment.
Specifically, greater than the first thresholding that presets, and the built application scenarios that has multisystem to share is selected described indoor distribution type AP equipment for construction area; Less than the second thresholding that presets, and the number of users of unit are is selected the described indoor dress type AP equipment of putting greater than the application scenarios of the 3rd thresholding that presets for construction area; Wherein, described the first thresholding is more than or equal to described the second thresholding.
That is to say, large for construction area, user distribution is wider and the built occasion that the indoor distributed system that multisystem share is arranged, should select indoor distribution type AP equipment such as scenes such as large-scale office building, commercial and residential building, hotel, airport, stations, the type equipment access indoor distributed system is as the signal source of wlan system, to realize the covering to indoor WLAN signal.Occasion and the zone larger to capacity requirement that, area less simple for building structure, user concentrate relatively, should select the indoor dress type AP equipment of putting such as scenes such as small conference room, bar, leisure centers, the type equipment can be implemented to distribute according to varying environment flexibly.
Then, in step 220, according to the plane general layout of application scenarios, determine installation quantity and the installation site of AP equipment.Such as, if the plane general layout be around the room around the plane general layout of type, the installation quantity N1 of the AP equipment of then determining, the installation quantity N2 of the AP equipment of determining when being long strip type less than the plane general layout.If the plane general layout is the plane general layout of hall, the confused with errors and omission type in room and corridor, the installation quantity N3 of the AP equipment of then determining, the installation quantity N2 of the AP equipment of determining when being long strip type greater than the plane general layout.Wherein, described N1, N2, N3 are natural number.The installation site of AP equipment is also determined according to the plane general layout of application scenarios.Such as, if the plane general layout be around the room around type, then signal is stopped that degree is greater than the installation site as AP equipment, the position (being that signal stops strong position) of pre-set threshold value.If the plane general layout is long strip type, then will be along the corridor evenly spaced several positions as the installation site of AP equipment.If the plane general layout is the confused with errors and omission type in hall, room and corridor, several AP equipment then are set in the hall, each corridor because wall stops each position that causes loss, AP equipment is set respectively.
Then, in step 230, according to installation quantity and the installation site of the AP equipment of determining, AP equipment is installed; Wherein, AP equipment all connects with netting twine to switch.
Specifically, be exclusively used in industry, science and field of medicaments ISM(Industrial Scientific Medical because the WIFI transceiver adopts) frequency range, frequency range is 2400 ~ 2484MHZ.Communication bandwidth 84MHZ.Carrier frequency separation is 5MHz.Totally 14 frequencies, sequence number (ARFCN) is 1 ~ 14.Because the direct sequence spread spectrum mode that AP equipment adopts, the interval of AP equipment tranmitting frequency has also determined the flank speed of transfer of data, and is when guaranteeing that maximum transmission rate is 11Mbps, just higher to space requirement between available frequency.So generally speaking, recommendation channel 1(Ch1) frequency, channel 6(Ch6), channel 11(Ch11) carries out multiplexing.And the same with mobile telephone communications network, in order to expand the coverage area and to improve the availability of frequency spectrum, WIFI also must need to introduce honeycomb, as shown in Figure 3.In general, during planning AP frequency, need to try one's best with two adjacent AP apparatus settings on the channel of being separated by.When AP is regular distribution, can be with reference to such as the frequency reuse mode among Fig. 3.
In addition, WIFI is interference limiting system, and the frequency that adjacent two AP equipment adopt affects and connects signal quality (Link Quality).Along with the increase of distance, signal quality and intensity are understood variation and are weakened.The signal quality and the transmission speed that receive there is no absolute relation, but signal quality is poorer, and expression is disturbed and causes the probability of online interruption to increase, if interruption times increases, then transmission rate can reduce.In theory, the common keying of CCK(CorporateControlKey with the DQPSK (difference binary phase shift keying) of 2Mbps modulation or 11Mbps) under the modulation system, single Packet(packet) long, 1024bytes.FER(frame error rate) less than under 8% the condition, require the isolation of adjacent frequency 〉=35dB.
Therefore, when the access indoor distributed system, need to confirm first that existing indoor distributed system is to the compatibility of WIFI frequency range in this step.If former indoor distributed system contains the device of not supporting this frequency range, need to change, this is not supported the device of WIFI frequency range, be replaced by the device of supporting the WIFI frequency range.Do not transform on original horizontal antenna Some principles, must not access the dried equipment of putting of WIFI.When AP equipment is installed, be different frequent points with two adjacent employed frequency point setting of AP equipment; Wherein, two adjacent AP equipment comprise two AP equipment every the floor same position.And when the installation quantity of determining AP equipment and installation site, the quantity that the same area same frequency covers the lower AP equipment of determining is less than or equal to 3.That is to say that adjacent AP equipment (comprising two AP equipment every the floor same position) should avoid using same frequency as far as possible, the AP quantity that the same area same frequency covers should be above 3.Should avoid using the frequency identical with existing AP as far as possible, use in principle 2.4GHz frequency range 1,6,11 3 frequencies.When outdoor area is found to disturb, also can adopt the adjustment antenna directional angle, the method for avoiding antenna main lobe to aim at interference source avoids interference.
In addition, when AP equipment was installed, what need make as far as possible also that the AP device signal can be vertical passed (an angle of 90 degrees) wall or ceiling.It will be understood by those skilled in the art that WIFI signal space propagation model as shown in Figure 4, area of coverage field intensity basis is as follows:
To indoor covering system, adopt the loss of electric wave free-space propagation to stop that in conjunction with barrier pattern carries out, its free-space propagation loss Ls computing formula is:
Ls=(4πd/λ)2=(4πdf/c)2
In the formula, d is transmission range, and unit is m; F is wave frequency, and unit is Hz; C is the light velocity, is specially 3 * 108m/s, and λ is wavelength.
Be shown with logarithmic table:
Ls(dBm)=10lg(4πdf/c)2
=20lg(4π/c)+20lg(f)+20lg(d)=32.45+20lgf(MHz)+20lgd(km)
Under actual indoor environment, what electromagnetic loss will consider building structure in the radio wave propagation blocks loss and multipath loss.That is: the signal strength signal intensity indication that receives of RSSI()=antenna opening power+antenna gain-free-space loss-block loss-multipath loss.Present stage, available 2.4G electromagnetic wave was as follows for the empirical value of the penetration loss of various building materials
1, partition wall stops (brick wall thickness 100-300mm): 20-40dB
2, stopping of floor: more than the 30dB
3, wood furniture, door and other plank partition wall stop 2-15dB
4, heavy sheet glass (12mm): 10dB
In addition, when weighing wall etc. for the penetration loss of AP device signal, need to consider AP device signal incident angle.0.5 meter thick wall of one side when the straight line connection is miter angle incident between AP device signal and the overlay area, is equivalent to, and penetrates 1 meter thick wall, is equivalent to penetrate above 14 meters thick walls when 2 spend angle incident.So that obtains that better reception should make as far as possible that the AP device signal can be vertical passes (an angle of 90 degrees) wall or ceiling.
In addition, in this step, preferentially select the optical fiber mode to access AP equipment, put dress type AP equipment preferentially (Passive Optical Network: passive optical-fiber network) mode accesses by xDSL (Digital Subscribe Line digital subscriber line) or PON as indoor.Related AP equipment in the present embodiment can adopt POE(Power Over Ethernet, Power over Ethernet) and two kinds of supply power modes of power supplied locally.Preferentially use in principle power supplied locally, can adopt the Ethernet switch with the POE function to carry out remote power feeding; Can't solve in the power supplied locally situation, and in the situation of AP negligible amounts, can be connected in series the POE external module.
Because in the present embodiment, the type of AP equipment is determined by the type of application scenarios, the installation quantity of AP equipment and installation site are determined by the plane general layout of application scenarios, therefore, coverage effect that can Effective Raise WIFI network, shorten construction period, save cost of investment, increase customer satisfaction.
In addition, it is worth mentioning that, in the present embodiment, is to describe as indoor application scenarios as example take application scenarios, if the construction of outdoor website then should take full advantage of the existing resource of telecommunications.Such as near Personal Handyphone System, global eyes station, the phonebooth point etc. of being provided with, should preferentially select equipment is placed this type of website, according to actual conditions, can utilize the resources such as existing power supply, antenna, vertical rod and cable.And outdoor AP still can preferentially adopt the optical fiber mode to access, and restrains by LAN switch at local side.Can use greatly at need wireless bridging as transmission can't adopting wired mode or exist.
The second execution mode of the present invention relates to the wireless access points equipment installation method in a kind of WIFI network.The second execution mode has provided the concrete AP equipment installation method under a kind of concrete application scenarios on the basis of the first execution mode.In the present embodiment, concrete application scenarios is for comprising the building housing-group in building, Building three (such as building 1, building 2, building 3).Wherein, the plane general layout in building 1 is that the room centers on type all around; The plane general layout in building 2 is long strip type; The plane general layout in building 3 is the confused with errors and omission type in hall, room and corridor.Building 1, building 2, building 3 belong to all that building structure is simple, area less, user are concentrated relatively occasion and the zone larger to capacity requirement, therefore, the type of the AP equipment of selecting in step 210 in the present embodiment is the indoor dress type AP equipment of putting.
In step 220 and since the plane general layout in building 1 be around the room center on type, therefore, can determine 4 AP equipment of common installation, be installed in respectively signal and stop strong position, particular location as shown in Figure 5, AP all connects with netting twine to switch.Because the plane general layout in building 2 is long strip type, therefore, can determine 8 AP equipment of common installation, prolong the corridor and spread out, particular location as shown in Figure 6, AP equipment all connects with netting twine to switch.Because the plane general layout in building 3 is the confused with errors and omission type in hall, room and corridor, therefore, can determine to install altogether 12 AP equipment according to actual conditions; Install 3 in the hall, play the effect of effectively bearing the user concurrent number.Stop the position that loss is larger in each corridor because of wall, the AP equipment comparatively dense of setting; Particular location as shown in Figure 7, AP equipment all connects with netting twine to switch.
Persons of ordinary skill in the art may appreciate that the respective embodiments described above are to realize specific embodiments of the invention, and in actual applications, can do various changes to it in the form and details, and without departing from the spirit and scope of the present invention.
