March Monthly Post: Get Faster Data Speeds

Requirements:

• Root
• Android Device

For all of those who own an Android and want faster data speed check out this application on the Google Play Store, called 3G/4G Speed Optimizer developed by Vista. This application optimizes your Data network speed so you can obtain better data speeds. Without this application, I would be getting around 1.27 mb/s download speeds and 0.24 mb/s which is not the best. And with the application enabled, I obtained 1.87 mb/s download speeds and 0.31 mb/s upload speeds, and from these results you can see the results of this application.

How it works:
It optimizes the Build.prop in your phone to obtain a better scan for data.

How can an RF Field Engineer best troubleshoot cellular coverage in a city?

Answer #3:

By troubleshooting the internal software within a Radio Base Station.

3 Details:

1. Two key issues in the implementation of software radios are the development of optimal receivers that require the minimum number of bits in the wide-band analog-to-digital converter (ADC) and efficient channelizers that extract individual channels from the digitized wide-band signal.
2. The idea of software radio is to place the analog-to-digital converter (ADC) as close as possible to the antenna, ideally right after the low noise amplifier (LNA) and bandpass filter (BPF), thus the remaining RF/IF functions, such as channelization, downconversion, synchronization, and filtering, can be performed digitally on a general purpose processors (GPP) to provide the full advantages of reconfigurability.
3. The main advantage of software radio is flexibility. Application developers are interested in software radio because operating characteristics of the radio can be changed on-the-fly: frequency band, modulation scheme, error correction, etc
