  1. dBm

  2. Types of batteries


The dBm (sometimes also dBmW or decibel-milliwatt) is a unit of measurement of power expressed in decibels (dB) relative to one milliwatt (mW). It is used in radio networks, microwave and optical fiber as a convenient measure of absolute power because of their ability to express both very large and very small values ??in short form. It is distinct from dBW, which refers to one watt (mW 1,000). Typical values:
  • 21 DBM-> 125 MW> Maximum output power for a mobile phone UMTS/3G (phone power class 4).
  • 15 DBM-> 32 MW> Typical power transmission WiFi laptops.
  • 0 DBM-> 1.0 mW = 1000 ?W-> Standard Bluetooth Class 3 coverage 1m.
  • DBM- -10> 100 ?W-> Typically the maximum Potentiometeria that can be received on a wireless network (-10 to -30 dBm).
  • -194 DBM-> 0.00004 AW-> thermal noise bandwidth of 1 Hz in outer space (4 kelvin).

Types of batteries

Within the wide range of batteries on the market we can differentiate two large groups, disposable batteries and rechargeable batteries.
Disposable batteries are those that only allow a single use and when they are exhausted they can not be recharged. These batteries can store their energy for years.

Rechargeable batteries are those that can be recharged once exhausted. This type is losing charge when they are storedaccording to voltage. The most common we can find them of 1.2V and 3.7V

As a last point you have to take into account that lithium batteries, Lipo, Life etc. Due to its composition, specific loaders should be used.
