Signal strength vs Speed

post #1 of 11
Thread Starter 
So I am soon going to be getting a mobile internet connection for my phone which I will be also using for some internet gaming (silly school internet blocking almost every single game out there) and my question is this.

Connection 1: 21Mbits/s 13e/month Signal strength 70%

VS.

Connection 2: 16mbits/s 15e/month Signal strength 95%

I'm getting the signal strengths from a website in my country that track different providers signals and I can see them on a map, I presume that is not 100% true anyways but I want to be sure to get the best one for the money.

So the question pretty much is should I get the faster one or the one with a better signal. Remember I will be gaming mostly!

Signal strength will likely have more of an impact on the consistency and latency of the connection, so the second one should be better for gaming.

Signal strength has no barring on latency unless it's causing packet loss thus re-transmission and even then it wouldn't be called "latency" but loss and jitter. There are other reasons for the "quantity of interest" to be demodulated with delay...

Understand that an EM wave propagates at the same speed ("near" speed of light) and it doesn't loss velocity as it transverses the universe... LOL It does lose "power density" though.

The DSP that decodes the OFDM wave though can add latency and it's ability to interpret the wave and errors in doing so can cause "latency" in the layman sense of the word. Fade can also cause this layman understanding of "latency".

This should help explain better than me...

Mobile broadband speed is heavily dependent on signal strength,
But for gaming mobile broadband is bad. Its not real Internet. A lot of simulation so dont expect miracles with latencies.
post #5 of 11
He's sure getting incredible speeds if it's a "3/4G" connection!!! The speed would have more to do with overhead on the tower your latched to or the reason the stronger one is getting less speed is due to multipath issues with the signal.

yes if the download is big. But latency? no
No matter what your provider says, it's not a real Internet connection (i.e. it is not using TCP/IP). Mobile networks emulate some protocols from the TCP/IP protocol suite, among them TCP, UDP and ICMP. They only do it to a certain degree and in most cases the emulation is not entirely transparent (for example, many providers reduce the quality of JPEG images when browsing Internet web pages to conserve bandwidth). To avoid applications running into timeouts all the time, many signal a successful TCP SYN-SYNACK-ACK handshake even though an end-to-end connection hasn't been established yet.

You'd think that poxy adjusting jpeg images would only affect HTTP traffic.

As for 3G/4G networks I was under the impression they use TCP/IP!

Are you sure your not confusing "Ack Regulators" for "long lived" TCP/IP flows?

They emulate it. Mobile networks havee to use arp proxies to get onto the Internet. To make matters worse they have to sent out 2 round trips at times to find its destination.
