Difference between 'G' and 'H'

[ahmedz123]

Hi

When my phone shows a 'G' signal at the top I can not open any webpages on my Sensation. However when it displays 'H' I can use the online services as usual. Should I be able to go online when i have a 'G' signal only?

What speed should be available on 'G' and 'H'?

You should get online with "3G"...But "H" is better..H is HSDPA..High-Speed Downlink Packet Access (HSDPA) Check this link for info High-Speed Downlink Packet Access - Wikipedia, the free encyclopedia

G in this context stands for generation of cellular network technology
1st generation is simple gsm for calls / texts and won't get you online (not counting wap... it's 2012 after all)
2G is gprs and if you see E, that's for edge (think of it as 2.5G) - both of these are fairly slow but get simple surfing done
and then there'e the quicker 3G and H (HSDPA - "3.5G")
next up 4G/LTE, but the sensation isn't capable of that
