Select the 3rd and 4th statements.
- They search for signals to confirm that service is available. — True. Mobile devices scan for and measure base-station signals (cell selection/reselection, handoffs).
- They provide voice communications and Internet connectivity. — True. Cellular systems carry voice and data (e.g., GSM/CDMA, LTE, 5G).
The others are false: cellular coverage is planned as cells (often idealized as hexagons), not a fixed “grid,” and cellular systems use standards like GSM/LTE/5G, not IEEE 802.11 (which is Wi‑Fi).
