How can guarantee WLAN characteristic is optimized
Though a lot of WLAN managers pay close attention to the fact in problem solving and avoid the safe loophole, WLAN characteristic optimizes and pays attention to the task list even more. Whether this method can not not merely consider thoroughly, and ignore and optimize or cause another factor of the disaster. If each AP only needs to support the flowrate of Net surfing of about ten users, the general characteristic can be accepted, but when AP is close to the heaped capacity and the utility program demand becomes higher, the bandwidth is consumed and the bottleneck will become very serious.
In order to realize WLAN characteristic is optimized, network manager and controller must use the new WLAN measuring and testing tool, they can check the network performance according to utility program type of running in the network. Looking for these tools will force the network administrator to look for more innovative products not including a present supplier and method of testing. Because these tools may be very expensive, their price may be several times higher.
Why need better WLAN performance test and network design?
Er early WLAN is usually according to empirical design, namely adopt circumference of coverage of one AP to show, among them the radius represents minimum signal intensity. Then use, stand spot scanning come, draw actual signal intensity, and with passive scan Or take the initiative ‘ Related Method about measurement. The tool used for carrying out and scanning is manual and labour-intensive; For example have a method require test clerk in carry on two measurement come on, collect passive initiative measuring result on the spot.
Obviously, these methods can’t well go on on bigger WLAN. More important, they can not reflect 802.11n and all kinds of increasingly many reliance actual function of high bandwidth and low delayed utility program. By using 802.11n, the transmission rate of different directions can be controlled, and the signal is strong might not be that one of the characteristic of the utility program can accept the index.
Gaugeable utility program demand of survey tool of WLAN characteristic
This is exactly the place where the new characteristic survey tool specially designed for 802.11n and important mobile service utility program can play a great role. For example, AirMagnet Survey not merely measures up run and link performance of descenting with iPerf, and it can be used for analyzing to offer 802.11n to recommend setting up and the fast pronunciation is assessed.
Veriwave WaveDeploy one comments on and estimates tools the acting station, it can produce test and flow, the hair reaches not only can measure TCP throughput, can still measure ” experience quality ” of Web, pronunciation and video behind the true customer end apparatus . An apparatus to adopt WaveDeploy of Pass The Test, the tester can produce the cover of the area that meet the requirement of the utility program to pursue. This is by measurement index for example, MOS and sound shake of each utility program Determination.
WLNA characteristic optimized: Test of persistent customer end
It is a complicated thing to optimize WLAN characteristic. After WLAN disposes, these new scanning tools should still continue using, in order to prove the performance objective has been satisfied all the time, and assess and plan to adjust and upgrade the influence brought. As time goes on, you may find there are completely different data rate and throughput in different customer end, even if send the same typological flowrate from the nearly identical position and do so.
For example in possible cases, meet abnormal low customer end of data rate, may refuse to roam a better AP. ” the unreasonable one ” The customer end not only throughput is low, but also they need to bring wide holding time to send the data of the same magnitude more. When the bandwidth competition is very fierce, each customer end will be influenced because of this unreasonable customer end. Need to use a piece of displacement means such as AirMagnet WiFi Analyzer at this moment, it can analyze the customer end is roamed and moved, discern unreasonable customer end and them to the characteristic of the utility program for instance, MOS divides Reality influence.
Use the fair algorithm of holding time to carry on RF measurement
Fixed test result course very useful to fine setting, forbid, find, will lead to the fact low the intersection of data rate and customer end that problem take place, or launch the customer and serve useful 802.11n and select. However, some characteristic questions are temporal, and it is and very responsive in the position to make the customer end up. If a visitor takes the problematic apparatus to the office, or just try to use WLAN in farther position, will present a slow customer end to tie down other customer end. The only effective method to deal with this kind of problem is to carry on measurement through real time response constantly.
Some WLAN suppliers have offered at present ” Holding time is fair ” The algorithm, can carry out real-time RF test, and use them to adjust the customer end and transmit the chance automatically. For example, when launching Dynamic Airtime Scheduling of Aerohive, it is assigned to transmit the chance. When the data rate of the customer end begin to drop, more quick customer end can obtain more transmission chances, thus optimize whole throughput. Then Performance Sentinel of Aerohive will concerned with real-time measuring result with each need and actual the intersection of throughput and goal of user these together closely. If SLA is unable to respond to the request that high flux supports customer end, NOC operating personnel will receive the obeying alarm.
WLAN testing tool of integration automation and sectionalization
Finally, most enterprise integration uses automation / centralization and moves / subdivides testing tool and method. As to some tasks, tests and are close to real time adjustment incessantly it is very significant with WLAN and WIPS basic framework. In some large-scale distributed networks that can’t carry on routine test, this method is very valid.
However, as to some other tasks, it is very valuable that the third party or handheld tool remains. The third party can offer one with testing tool ” The onlooker ” View. The displacement means can offer the flexibility to be higher than AP or sensor-based test. Though these tools may all need buying or training extraly, they are very valuable in looking for the loophole, debugging the question or isolating the characteristic question.
Perhaps the most important thing is to avoid short-sightedly, can’t always test your WLAN with products or tool that your supplier offer directly. This market changed fast will change as enterprises WLAN employ increasing.
