ESChat and Data Usage

Nancy Rodgers
  • Updated

Data usage is dependent on the device type and network service in use (3G, 4G, 5G, WiFi). 

For all network types:
  • Packet Latency :  200ms is our maximum allowed by default, not what we expect. Actual performance will be network and QoS dependent.
  • Packet Loss: We expect 0% but that expectation depends upon network performance. 
  • Jitter: Our default jitter buffer is 320ms.  Actual performance will be network and QoS dependent.

While ESChat is not in call:

  • ESChat usage is approximately 20 Megabytes/month regardless of device and network type.

While ESChat is in-call, and in-call location is enabled: 

  • While ESChat is in-call and a user is transmitting or receiving voice:
    • 4G/5G/WiFi : approx 23 megabytes/hour (384 kilobytes/minute)
    • 3G : approx  8.2 megabytes/hour (137 kilobytes/minute)
  • While ESChat is in-call, and nobody is talking:
    • Approx 403 kilobytes/hour (6.7 kilobytes/minute)

While ESChat is in-call, and in-call location is disabled: 

  • While ESChat is in-call and a user is transmitting or receiving voice:
    • 4G/5G/WiFi : approx 22 megabytes/hour (367 kilobytes/minute)
    • 3G : approx  8 megabytes/hour (134 kilobytes/minute)
  • While ESChat is in-call, and nobody is talking:
    • Approximately 273 kilobytes/hour (4.6 kilobytes/minute)

Examples:

Assume that you typically make calls that use 10 hours of talk time during a month on your :

  • 4G/5G/WiFi network , expect to use 220 megabytes/month (without location) or 228 megabytes/month (with location).
  • 3G network, expect to use 80 megabytes/month (without location) or 81.6 megabytes/month (with location).

Bandwidth:

Here are the minimum bandwidth rates for each type of connection:

  •  4G/5G/WiFi: 40 kbps
  •  3G: 18 kbps
  • Satellite  (Thales MissonLink only): 9.6 kbps

Please check with your provider for any special promotions or packages they might offer.  

Audio Codec Rates:

Here are the audio rates for each type of connection:

  • PCMU: 64kbps  / 1 packet per 20ms
  • 4G: 32kbps / 1 packet per 40ms
  • 3G: 14kbps / 1 packet per 100ms
  • 2G: 8kbps / 1 packet per 160ms
