Hello to all,  
I am working on the LoRaWAN network.  
I got some problems at the time of connection.  
If I connect 10 end devices, that time all 10 end devices connected to the gateway.  
But if I increase the end device quantity that time some end devices unable to connect to the gateway.  
I want to connect the 1000 end device to a single outdoor gateway.  
So can anyone give me a solution for this?

Hi for OTAA join the gateway must send and those are limited to.  
After the join a gateway will likely support more that 1000 end nodes.

Be aware that you’re gateway could fail and then the communication will be halted, for 1000 end nodes I would try to get two "independend"gateways. Would be good for you’re peace of mind.

See, emphasis mine:

> [@Multiple new devices trying to OTAA](https://www.thethingsnetwork.org/forum/t/multiple-new-devices-trying-to-otaa/8813/2):
>
> … you are probably running out of airtime for the gateway which has to adhere to the same limits a node is subjected to. If I recall correctly the console might list a message in the device data stating there is no gateway available to send the response.
> 
> If there is no gateway available to transmit a packet (join response or downlink) it is discarded. For joins a new join request will be sent by the node for which a new reply will be generated by the back-end.
> 
> **You could add gateways at your location to increase the available downlink capacity.** TTN will choose the gateway with best link and available airtime to transmit a packet.

Or: simply do not make 1,000 devices try to join at about the same time. Why would you need that?

See [Multiple new devices trying to OTAA](https://www.thethingsnetwork.org/forum/t/multiple-new-devices-trying-to-otaa/8813) and [Best approach to OTAA join for multiple devices turning ON at the same time](https://www.thethingsnetwork.org/forum/t/best-approach-to-otaa-join-for-multiple-devices-turning-on-at-the-same-time/24586).

hello @arjanvanb,  
I jst want to connect multiple end device through OTAA to gateway,  
so for that, there is any change i need to do in programming, there is any algorithm i need to foloow

Just do not switch on/join all devices at the same time. Wait 10 minutes between devices and you should be fine **if** your devices do not send uplinks with ack requests very often (each device may only request 10 downlinks a day anyway)

And just to be sure: you should not do an OTAA join for each uplink, if that’s what you’re doing. See [How often should a node do an OTAA Join, and is OTAA better than ABP?](https://www.thethingsnetwork.org/forum/t/how-often-should-a-node-do-an-otaa-join-and-is-otaa-better-than-abp/11192) and [OTAA best practice: how to not join every time?](https://www.thethingsnetwork.org/forum/t/otaa-best-practice-how-to-not-join-every-time/14601)

Hello @kersing,  
I read your following topic,

> [@Best approach to OTAA join for multiple devices turning ON at the same time](https://www.thethingsnetwork.org/forum/t/best-approach-to-otaa-join-for-multiple-devices-turning-on-at-the-same-time/24586):
>
> Hi everyone I have been trying to get the OTAA done perfectly , and this forum has helped a lot in the purpose. Thanks for that slight_smile The question is What is the best practice for OTAA devices if there are 20 devices booting at the same time and asking for a join request on TTN Gateway? Many a times . the join get accepted , but the data doesn’t make it through for some applications. What can be the possible solution for this? Thanks

in that, I got some idea to connect multiple end devices to single gateway.  
I have some question that,

1. there is any effect of ADC value?
2. if yes, whats is the effect? How I solve the effect?

Please start with studying LoRaWAN, the [LoRaWAN academy](https://lora-developers.semtech.com/resources/lorawan-academy/) would be a good resource. That should provide you with insight into what is relevant and what is not with regards to joining.

And keep in mind nodes do not join to a gateway. That is WIFI speak. In LoRaWAN nodes join a network. That distinction should be obvious after you completed the academy course.
