"How The Right Antenna Could More Than Double Your Speed"

Antenna boost Speed

Omni Antenna:

  • Benefits are that it can receive a signal from virtually all directions. I.e. the mobile or LTE enabled router can roam across various cellular mobile base stations in any direction. If the one cellular base station (tower) is congested or faulty, then the possibility of receiving another site is better than when compared to a directional antenna. You will, therefore, have a better probability to maintain good connection stability in these situations.
  • A disadvantage is that you will also potentially receive interference from all directions, which could degrade your experience. So, the benefit above could also be a disadvantage in higher interference areas (interference is the reception of unwanted signals that can degrade your experience).
  • The overall gain of the Omni antenna is lower, so the peak throughput is lower when generally compared to the directional antenna.
  • An Omni antenna is easier to install than a directional antenna and it does not require realignment/adjustment when the network changes (new sites, network problems, etc.).
  • Here are a couple of our best performing Omni-antennas for LTE:                         

 Directional Antennas:

  • When you are far away from cellphone towers and only have a marginal signal reception from a single site, then a directional antenna is often a better choice.
  • The benefit is that the signal from the target direction is improved through the directivity gain (like amplification). The gain from other directions is reduced as a result and hence the interference (unwanted signals) is suppressed. This can improve the Carrier to Interference Ratio (C/I) where a higher C/I is beneficial in cellular and other radio frequency (RF) systems reception. The signal reception stability is better for this reason, but only while the target base station (tower) is not congested nor faulty.
  • When the site to which you have directed the antenna starts performing poorly, you may need to re-align the antenna.
  • Implementation of the antenna may be more complicated as the antenna must be directed towards the target base station or transceiver. Selecting which site to direct the antenna towards is not always easy.
  • When the cellular base station (tower), which your antenna is directed towards, becomes congested or faulty, then the impact will become more severe when compared with an Omni antenna. From a general stability perspective, the omnidirectional antenna might be a better choice.
  • When the ability to receive a signal where there is virtually no signal or an area with high interference, then a directional antenna can be considered.
  • Here is one of our most recommended directional antenna.

 To Summarize:

  • Omni – better reliability overall (especially in cellular site outages and congestion scenarios). Slower throughput and less efficient in difficult areas. A better option for urban/suburban areas with sufficient cellular base station sites.
  • Directional – better throughput, but when the cellular base station is congested or out of service, then the experience can become terrible. This is where the Omni will perform better. However, in difficult areas (mostly distant rural areas) the directional antenna does reduce interference from other sites which are not in the same direction as the target site – this is what improves the C/I and thus the throughput.
