Given a query, you need to generate five useful documents for the query.

The user is trying to answer the question: "what is the minimum speed of 3g network?" whose answer is 2 Mbit/s.
Each document should contain about 30 words, and these documents should contain useful information.

Query: minimum speed 3g network
Useful Output:

Doc 1: The average download data speed for 2G GSM networks is 30-50 kbps using the EDGE technology; the average speed for 3G UMTS networks on Evolved
Doc 2: The International Telecommunications Union (ITU) said it expects 3G networks to facilitate “a minimum speed of 2Mbit/s for stationary or walking
Doc 3: 3g: Bandwidth of at least 144kbps. 4g: Bandwidth of at least 2mbps (more generically: speeds that enable the use of multimedia, video, etc).
Doc 4: 3G offered 144 Kbps of throughput at mobile speeds, 384 Kbps at pedestrian speeds, and 2 Mbps in indoor environments.
Doc 5: The average speed of 3G connections is 3 megabits per second (Mbps), which was 30 times faster than 2G average speed of 100 kilobits per second
