Experiment with different antenna positions until you have reduced the range of the wireless signal. DTIM stands for Delivery traffic indication map or message. It is basically an additional message added after the normal beacon broadcast by your router or access point.
The default value is 3. Wi-Fi MultimediaShares. WMM Wi-Fi Multimedia is an automated service that gives priority to multimedia running through your wireless network. Beacon frame is one of the management frames in IEEE It contains all the information about the network. Some routers give the end-user significantly more flexibility to play with the advanced settings of their WiFi, such as by adjusting the options for Beacon Interval, Fragmentation Threshold, RTS Threshold or various other things.
Generally speaking you should leave these well alone as most adjustments will often sacrifice something in one area in order to improve it in another and if you get this balance wrong then problems can occur.
But if you do want to try then here are a few quick suggestions. Setting a lower e. By contrast raising the setting above ms could save power but the likelihood of connectivity problems may increase. The RTS Threshold protocol is a tricky one to explain, but it helps to clear the channel before data is sent.
A lower setting may help in busy WiFi environments as it should reduce collisions, but set it too low or incorrectly and your network performance may suffer. Any data packets larger than the size programmed in this field will be fragmented. Setting smaller packets than the default can improve reliability, especially in busy environments, albeit at the cost of performance. Most routers allow you to make a backup of your current settings, so do that before attempting anything like this as it may come in handy.
Depend on scenario this may speed up or slows down the network. One aspect is, if connected clients are less then this is a good idea but for more clients AP will take more time to send multicast data to all connected STAs.
As per my knowledge, some Qualcomm AP supports this feature. Hi I have few questions. First unicast data packets TX will takes place later multicast follows. If there something wrong pls let me know. If you know any scenario where unicast is more priority than multicast then you can share.
DTIM count will be 2 1 If you have seen anywhere then please share , we will see that. For unicast STA can wake up on listen interval time. Your email address will not be published.

You'd have to set up a special, sensitive test to look for any difference, and I'm still not sure you'd be able to reliably measure one.
We initially changed the IPods to not "auto lock" which turns off battery saving, however battery life was reduced to 4 hours maximum, which was not acceptable. My experience says voice packets need 2 and some specialty devices, i. Vocera, may need 1.
If you are an in-home user then you can set it to 3 or 4. Sign up to join this community. The best answers are voted up and rise to the top. Stack Overflow for Teams — Collaborate and share knowledge with a private group.
