Wifi Question

[1D4LV]

Guys, tanong ko lang baka may nakagawa na sa inyo neto.

We have three access points that are spread out sa buong floor.
A user connects to a specific access point when he is in his working space.
Ang gusto ko mangyari, pag lumipat sya ng lugar, bibitaw yung connection nya sa default connection nya and connection nya would be transferred to the access point nearest his new location automatically. Pag bumalik sya sa workspace nya, babalik yung connection nya to the original access point.

Tanong-tanong lang. Users are connected via multiple devices (laptops, mobile phones, tablets). Laptops are on Mac and on Windows and tablets are on iOS and Android.

Do i still need to lower down the broadcast capacity of each AP? Hagip din kasi yung signal sa buong area maski saan ka magpunta.


Medyo naging clueless ako dito ah.

The WIFI devices (laptop, tablet, smartphone) will just automatically switch to the strongest listed WIFI signal once it's original signal has become weak and unstable. TO maximize WIFI network performance, just make sure the channel frequencies are not using the same number (usual default is 6 for most wifi router devices). Lowering the broadcast power would help to minimize interference. Interference will can cause wireless network slowdown. How much power to lower? Depends on the devices, some are sensitive while others need a very strong signal to connect well.

To minimize the need for many AP, place your AP high like the ceiling or upper part of a wall.

Probably you have to lower the signal for the AP's para di mag overlap..

Curious lang ako bakit ganun gusto mo mangyari?

Make sure that all APs are configured with the same SSID, encryption type, passphrase and are configured on non-overlapping channels (Ex. Ch. 1, 6, and 11 for the three AP's).

On Windows PC's, there's usually a parameter in the Advanced tab of the wireless adapter called Roaming Aggressiveness. The default value is 3 and if you increase it to 4 or 5 (max), it will become more aggressive in connecting to an AP with a higher quality signal.

Here's the definition from Intel:

Roaming Aggressiveness
This setting allows you to define how aggressively your Wi-Fi client roams to improve connection to an access point. Click Use default value to balance between not roaming and performance.

Lowest: Your wireless client will not roam. Only significant link quality degradation causes it to roam to another access point.
Medium-Low/Medium-High: Allow Roaming.
Medium: Balanced setting between not roaming and performance.
Highest: Your Wi-Fi client continuously tracks the link quality. If any degradation occurs, it tries to find and roam to a better access point.

The key term to understand here is signal quality. Signal quality is a measurement based on signa-to-noise ratio (SNR). Sufice to say that a weak signal with high SNR is better than a strong signal with poor SNR.

Analogy and example of SNR applied to real life:

Poor SNR:
Two people in a rock concert or a loud bar, standing 3 feet away will probably have difficulty understanding each other even if they shout.

Good SNR:
Two people in a quiet room, standing 15 feet away will probably understand each other clearly even if they speak at a normal volume.

On iPads and Androids, I don't think there's a setting for this. I may be wrong, though. I haven't really found a reason to change these parameters.

ok guys. thanks. sounds logical.

to avoid lang heavy usage on a single AP. guys are moving most of the time kasi, pero ang nangyayari is lahat sila ay naka connect dun sa single AP. ang gusto ko sana is pag medyo lumayo ang tao dun sa main AP, mag free up ng resource and ililipat sa iba.

what I am thinking din is to have a permanent connection ng mga units sa isang AP via mac address enrollment... kung saan naka connect ang isang device, dun na sya permanently...

btw, using Unifi APs.... maximum load is 20 connections. usually, each person has around 2-3 devices connected simultaneously.
internet naman is no problem. using one 15 mbps and one 10 mbps, on a link-load balancer.
