In the CompTIA A+ Core 1 (220-1201) networking concepts, satellite internet is commonly associated with higher (increased) latency compared with terrestrial options like cable, fiber, or DSL. Latency is the delay between sending data and receiving a response. With satellite, signals must travel from the user’s dish up to a satellite and then back down to a ground station (and return again for responses). That long travel distance adds noticeable delay, which can affect real-time activities such as VoIP, video conferencing, and online gaming. Even though newer low-earth-orbit (LEO) systems can reduce latency compared with older geostationary systems, satellite service is still generally discussed in A+ as having higher latency characteristics to consider.

The other options do not best fit satellite internet. Proximity to urban infrastructure (A) is more relevant to cable/fiber availability. An eSIM requirement (B) relates to cellular/mobile service, not satellite broadband. Line of sight to a nearby tower (C) describes cellular or fixed wireless services that depend on tower connectivity; satellite instead needs a clear view of the sky toward the satellite (not a nearby tower). Therefore, increased latency is the best characteristic to consider.
