Antenna Terminology Antenna Terminology
Electronics require antennas to convert data into RF signals (and vice versa). They are coupled
with radio transmitters and/or receivers to process the information that is carried over cellular
bands. Antenna design and functionality has evolved over time:
Internal Antennas: Internal Antennas: An antenna can be concealed within the casing of a device, as seen with
most smart phones. Internal antennas are potentially more prone to interference due to the
close grouping of electrical components.
External Antennas: External Antennas: Situating antennas further away from the rest of the circuit board can help
alleviate this problem by maximizing a device's natural reach. Instead of sitting inside the device
directly next to the modem or transceiver, they screw into place using SMA connectors and
protrude from the equipment (think "rabbit ears").
MIMO: MIMO: Multiple-Input and Multiple-Output (MIMO) technology expands the throughput capacity
of a transceiver by leveraging multiple antennas to simultaneously convert RF signals into data
(or vice versa), providing faster transfer speeds as a result. Think of it (loosely) as Carrier Carrier
Aggregation Aggregation for antennas -- once again combining individual lanes into a single, coordinated
superhighway. Networks must leverage MIMO antenna transmission to be technically
considered 4G.
