In the past, most satellite communication was provided over Ku-band. Today, Ka band is becoming increasingly popular and the band often recommended by satellite service providers in many areas of the world.
There are several different advantages to Ka band satellite services that are worthwhile considering for any business. As with most technology, Ka or Ku-band may be both be possible and acceptable, so it may be the slight differences and details that will tip the scales.
When considering the information from the top Ka band satellite services, there are several points that will stand out to businesses of all sizes. Keep in mind that the Ku-band operates in the 12-18 GHz frequency range while Ka band is in the 26.5 -40 GHz range.
Weather Issues
An issue known as rain fade is an important consideration for a business. This is sometimes called environmental interference, and it occurs when precipitation, either heavy rain or wet snow, cause the signal to fade. Both Ku and Ka band can have some level of impact from environmental conditions, but Ka band, with shorter wavelengths, is slightly more problematic in the heaviest precipitation.
With new technology and options that are built into the infrastructure of these systems, the best Ka band satellite services have addressed this issue, and it is not a concern.
Antenna Requirements
The size of the antennas required for Ka band satellite services is less than a quarter of the size required for the Ku band connection. This makes the Ka band easier to deploy and also makes it easier to move and use in very remote locations.
For most businesses, the deciding factor of the Ka band over the older Ku band option is the throughput. The Ka band can offer greater data transmission, which makes it a clear winning for many businesses, companies, agencies and even for the military and defence industries.
