2G VS 3G DRIVE TEST WITH TEMS LEXCORP SOLUTIONS The document compares 2G and 3G networks and discusses performing drive tests using TEMS equipment from Lexcrop Solutions to measure key performance indicators (KPIs) such as dropped calls, call setup failure rates, handover failure rates, swapped feeders, signal strength, signal quality, and more. The TEMS equipment includes devices like the T610 and K800 for measurements, GPS, data cables, and laptops to analyze results from 2G, 3G, HSPA, and LTE networks during mobile or stationary tests.

1)To obtain sufficient coverage over the entire service area to ensure that high quality
voice services and data services with low error rates can be offered to the subscribers.
2)To offer the subscriber traffic network capacity with sufficiently low blocking and call
dropping rate.
3)Keep the call from dropping as mobile move out from individual cell
