FMB AVL ID

https://wiki.teltonika.lt/view/FMB_AVL_ID

• No. = old AVL ID (dismissed)
• Property ID = new AVL ID

All of the AVL ID's that are above 255 need to use Codec 8 Extended instead of Codec 8. The reason being, that Codec 8 AVL ID's have 1 Byte (Maximum value 255), while Codec 8 Extended has 2 Bytes for AVL ID's (Maximum value 65535). Also Codec 8 Extended can have variable size I/O elements.

Record and packet size

An AVL record contains basic AVL data. An AVL packet conveys one or more AVL records. An AVL packet is sent trough the cellular network as a cellular packet.

AVL record size:

• minimum: 45 bytes (all IO elements disabled);

• maximum: 783 bytes.

AVL packet size:

• minimum: 1 record;
• maximum: 1 kbyte (for FMB devices).

Most cellular network operators have a minimum billed packet size of 1 kbyte.

The cheapest way to set up the device would be to send as many records as they fit in a maximum size packet 81 kbyte).

Typical data consumption

Cellular data consumption depends on cellular network operator (tariff in home/roaming, what is charged and what is not). For example - some operators take extra fee for data session establishment; in this case, customers configure devices to hold a session open for all the time the vehicle is driving.

It also depends on how often device will send data, so configuration also matters.

Sending protocol:

• TCP uses different amount of data (headers, confirmations etc.);
• UDP uses about 3 times less traffic data then TCP.

So it is possible to have 2-3 Mb per month, or 10-15. All depends on your application and requirements.
