I want to create an application which hosts a sever in my phone and many people can use it after connecting to my wifi hotspot.

Suppose I want to implement it in a classroom with 50+ students, is it feasible?

I want to know how many clients can be connected to the wifi hotspot. Are there any limitations?

  • It's just another Q&A with no sources, but this would seem to indicate that it's not possible to connect that many devices - stackoverflow.com/questions/22680293/… – Saiboogu Jan 28 '15 at 18:50
  • If you search for android wifi hotspot maximum connections, most of the results mention 5, 8, 10,.. but nothing close to 50. The issue seems related to hardware capability, including overheating due to too much activity. – Andrew T. Feb 6 '15 at 6:51
  • The "normal" wifi hotspots limit it at least to 253 connections by using an IP-address like 192.168.43.x. So far I haven't seen one using 172.16.x or 10.x addresses. – ott-- Feb 6 '15 at 15:08
  • The software limit seems to originate from the /data/misc/wifi/hostapd.conf file which is generated by the system based on /system/etc/hostapd/hostapd_default.conf. Most phones have hard limits of 8 or 10 devices, yet some of them don't seem to have a limit built in. Your milage may vary depending on the device you're using. – gertmenkel Aug 16 '16 at 23:34

Note: Partial answer regarding no. of hotspot connections that can be connected to a device.

Google on the page "Set up tethering or portable Wi-Fi hotspot" has stated:

If your device has mobile data, you can turn it into a portable Wi-Fi hotspot for up to 10 other devices, like laptop computers[.]

See also,

These features depend on your mobile device and your carrier. You may be charged extra for tethering or Wi-Fi hotspot connections. If you have issues, check with your carrier to see whether tethering can be enabled.

As Andrew already mentioned in the comment, the results on web usually tells the limit to 5,6,8,10, but not more than 10.

I could not find any content that states that hotspot could connect more than 10 devices. One person mentioned(I asked) a limitation vaguely here(in the comments).

IMO, you can't connect more than 10 devices, not without a hack. And to hack, you need to know why you can't connect more than 10 devices?

Please, do ping here if you(reader) come to know the reason.

  • For rooted devices, od you know how to increase this limit? Thanks – Trung Jul 16 '17 at 11:29
  • I'm sorry. I do not know. – Firelord Jul 17 '17 at 17:50

if you are using 3g then you provide wifi for 5 connections and if you are using 4g then 10 clients can use hotspot.

    Can you provide a source? Is this device dependent? Will one answer confidently work for all? – wbogacz Aug 16 '16 at 12:34

    and what if you don't have a mobile data connection at all? – Dan Hulme Aug 16 '16 at 13:10

There can only be a 5 clients at a time on a Wi-Fi hotspot.

    Supportable statement through documentation? Please supply a link. – wbogacz Nov 8 '15 at 0:20

    What? My phone (a Micromax A350 running Android 4.4.2) says I can have 8 clients connected simultaneously to my hotspot. – Tamoghna Chowdhury Nov 9 '15 at 5:26
