Review Step 2c: Characteristics & Trade-offs

Satellite (cont.)

With improvements in satellite technology, data rates are increasing with next generation GEO satellites (HTS), new MEO satellites and emerging LEO deployments. LEO satellites have the particular advantage of lower latency, although deployments have shown that GEO latency is acceptable for VoIP and video calls and MEO latency is within range for MNO 4G deployments. Figure 26 illustrates the differences between GEO, MEO and LEO constellations.

Note: Not depicted are small satellites, nano satellites, cube satellites in the 50kg to 500kg range that are typically used for gathering scientific data and radio relay.
