Table 1 High-level overview of the characteristics of different wireless technologies

From: Insights in the cost of continuous broadband Internet on trains for multi-service deployments by multiple actors with resource sharing

Parameter Satellite network Cellular networks Wireless data networks
Bandwidth High Low to very high High to very high
  (2 to 50 Mbps) (0.17 to 14.4 Mbps) (2 to 50 Mbps)
   (4G: 0.1 to 1 Gbps) (WiMAX 2: 0.1 to 1 Gbps)
