Based on the provided reference, the maximum data rate for Bluetooth, considering the versions listed, is 3 Mbit/s.
Bluetooth technology has evolved over various versions, each offering different capabilities in terms of speed, range, and power consumption. Data rate is a key metric defining how quickly information can be transmitted.
Bluetooth Data Rates by Version
The reference compares two specific versions: Bluetooth v2.1 (representing Classic Bluetooth with Enhanced Data Rate) and Bluetooth 5 (specifically the Low Energy variant mentioned). The table from the reference provides the following details:
| Feature | BLUETOOTH v2.1 | BLUETOOTH 5 (LE) |
|---|---|---|
| Frequency | 2.402 – 2.481 GHz | 2.402 - 2.481 GHz |
| Max data rate | 1- 3 Mbit/s | 2 Mbit/s |
| Application Troughput | 0.7-2.1 Mbit/s | Up to 1,360 kbit/s |
| Topologies | Point-to-point, scatternet | Point-to-point, mesh network |
As indicated in the "Max data rate" row of this comparison, Bluetooth v2.1 offers a maximum data rate of up to 3 Mbit/s, while Bluetooth 5 (LE) lists a maximum data rate of 2 Mbit/s. Therefore, the highest theoretical maximum data rate listed in the provided reference is 3 Mbit/s.
It's worth noting that the "Application Throughput" values represent the actual usable data speed after accounting for protocol overhead, which is typically lower than the raw "Max data rate".
