Wow, it really gives you a headache reading this thread. A few things.
1.) 4g is a marketing term. Like "More bars in more places." It really does not mean anything. What proof? 3g just must allow voice and data simultaneous and a minimum of 200kbps connection. Do you have voice and data, with a minimum of 200kbps? IT IS A MARKETING TERM JUST LIKE 3G WAS.
2.)Speeds are only in theory. Do me a test. Go here,
T1 | Business Broadband & Voice Provider | Speakeasy Inc.. Run a speed test from your normal pc. Do you have 100mbps connection? There is no way in H.E double hockey sticks you are going to get a wireless connection of 100mbps when a fiber optic land line can not do it. You understand? If the fast speeds across the internet is only 21mbps. You are only going to get 21mbps. You are not going to get anything faster, because the internet, in the united states is privately owned mess.
3.)4g is 100mbps mobile, 1gbps fixed, please understand that.
4.) Hspa+ is a marketing term. The only truth it contains is the fact that it can go faster then 3g. But has to use 20hz bandwidth to do that. If you take 20hz bandwidth from a tower, you have taken most of the bandwidth on that tower. Most hspa+ towers get 20-40hz, which means that the magic maximum is only possible with 2 or less people using the system. Depending on the build, speeds drop dramatically once you start adding more and more people.
But let me digress, alphabet soup, warning geek speak.
1g technology fhss/dsss
2g technology tdma/gsm- edge
3g technology cdma, ofdm- evdo/edge/hspa+
4g technology ofdma- Wimax/lte
1g,2g,3g,4g is about how you split of the bandwidth, not really how fast it goes. When you increase the number scale you increase speed, but not always. Thank you Hedy Lamar, with love ROI
