我使用的是RN1478，我对这个范围有点失望：视线中只有几米，这对于0 dBm的功率和90 dBm的灵敏度来说太短了。除了使用更多的引脚之外，使用RN48 70还有其他优点吗？谢谢，非常感谢

I'm using a RN4871 and I'm little disappointed about the range: only few meters in line of sight, which is a little too short for 0 dBm of power and -90 dBm of sensi
tivity.
How much range I will gain using a RN4870 instead of RN4871?
Are there other advantages using the RN4870, besides the more pins to use?
Thanks and best regards
Guido
