Kindle Fire HD is 4G LTE capable, iPad 3 aint; and predictions for 4G capable iPhone 5 are out. However, Kindle Fire HD is grabbing the attention. However, to compare the speed of these devices it is not fair to count on LTE. Here comes, the comparison of Wi-Fi download speed of Google Nexus vs iPad 3 vs Kindle Fire HD, diretly from the official Kindle fire HD page.
Two Antennas, Better Bandwidth
This is what makes bandwidth faster in Kindle fire HD, the first tablet to feature dual Wi-Fi antennas and Multiple In/Multiple Out (MIMO) technology for powerful, HD-ready Wi-Fi. This allows reception or transmission over both antennas simultaneously to increase capacity and reliability. So you’ll enjoy fewer dropped connections, more than 40% faster media streaming, and be able to go further from your wireless hotspot than with other tablets.
Dual Band Support in WiFi
Many Wi-Fi devices, from other tablets to baby monitors, only operate in the 2.4 GHz band. The more of these devices that you and your neighbors have operating in the band, the slower your connection is. Kindle Fire HD is capable of automatically switching between the 2.4 GHz and 5 GHz Wi-Fi frequencies, which will allow you to use this less congested 5 GHz band for better range and less interference.
