Hi,all:
This is a junior engineer who is doing some work related to LTE. Before i come here, i only read the 3GPP specs, which ignore a lot of implementation detail. Several days ago i heard openlte. I get Lte code and read a lot of useful discussion. Thanks to all the contributors.
To learn openlte well and do some contribution if i can in future, i want to build one test environment firstly. In the readme file, testing configuration is required as following:
- Intel Core i5-2557M
- Ubuntu 12.04
- Intel Core i5-2557M
- Ubuntu 12.04
- GNU Radio 3.7.2
- GrOsmoSDR 0.1.1
- rtl-sdr 0.5
- UHD 3.6.0-1
- HackRF 0.2
- bladeRF 0.9.0

I have one pc with i5 core and ubuntu OS, but i am not familiar with the left configuration. I search them in internet, and know they are develop-platform.So i wonder:
1, where i can get the required items such as GNU radio, GrOsmoSdr and so on?
2, How much i will spend on them?

Any reply is warmly appreciated.
BTW, I am at shen zhen of china, if any guy is also at shen zhen, ur help may be much more useful.

With my best regards

Brick
