Configuration 2.1 MEC Hardware Setup Cables should be connected as shown in the image. 2.2 Ip address configuration (Optional) The default configuration is static with IP address 192.168.2.16, and you can change this IP following below operations. Login via SSH user: miab password: root@123 Edit IP configuration file with below command sudo vi /etc/netplan/01-netcfg.yaml Save file and exit To apply new configuration, use below command sudo netplan apply 8 3 Provisioning of execution and configuration 3.1.0 Provisioning of execution and configuration for RF1 Provision 1. Open terminals as required (min 3) i. Run the command in all the terminals ssh root@192.168.2.16 pass- root@123 3.1.1 Execution of L1&L2 For 4x4 Transmission For L1 2. Perform following steps for run processes: -

i. To run L1 binary enter following command: -

-> Go to first tab of terminal and enter path for L1 cd /opt/FCC_DEV0/L1/script Some Details required for running L1 Now first open the L1_NR.cfg by using the command vi ../cfg/L1_NR.cfg Go to the insert mode by pressing i key and edit the parameter. To change the Sampling Rate parameter Uncomment (Remove #) the samplingRate_kHz value according to the channel bandwidth as shown in below picture. To assign antenna port value Set the sdrTxSubdevSpec and sdrRxSubdevSpec should be given in the picture. If it is not similar to configuration in the L1 config file, then make it like this:

Once done, save the file press ESC and type command :wq then press ENTER. Now Run L1 by using this command

./runL1.sh dpdk For L2 To run MAC_NR binary enter the following commands in second terminal

-> Go to second tab and change path for MAC_NR cd /opt/FCC_DEV0/L2/src

-> To edit config file of L2 refer point (c) Configuration from page number 5 (Use another terminal)

-> Run L2 by using this command taskset -ac 20,21,84,85 ./MAC_NR 0 Once done, both L1 and L2 are live. Now just press ctrl+c after at least 10 seconds on the L2 terminal. Go to the L1 terminal, comment (Add # at the starting of command) on the previous sdrTxSubdevSpec and sdrRxSubdevSpec parameter, and uncomment (Remove #) the sdrTxSubdevSpec and sdrRxSubdevSpec, which are shown in the below picture. After that, just save the file, press ESC, type command :wq then press ENTER. Once done, run L1 and L2. Wait for some time until "L1 is now live" is visible on the terminal, then both processes are up. Once all LEDs are glowing on RF1, you are able to take observations on the 4 TX ports. Note: Whenever you want to change frequency and band, you need to repeat the above process. 3.1.2 Configuration for config file 3. Perform following steps for opening configuration file :-

i. Go to the third tab of terminal ii. Enter cd /opt/FCC_DEV0/L2/cfg for config path iii. Enter vim config.cfg to open config file in vim text editor. iv. After completion of vim command a list of parameters will appear as shown below. 10 Note : When you want to change frequency according to band, first edit the config file of L2

(above picture), then save it. After saving, first run L1 by using ./runL1.sh and then L2 by using taskset -ac 20,21,84,85 ./MAC_NR 0 4. Perform following steps to modify configuration file :-

i. Go to the insert mode by pressing i key and edit the parameter. ii. To save the file press ESC and type command :wq then press ENTER iii. If dont want to save file, press ESC and enter command :q! then press ENTER 3.1.3 MIMO (multiple input, multiple output) configuration Note : It is already defined 4x4 MIMO in config file of L1. i. Open new terminal and do ssh root@192.168.16 and provide password root@123 and the command below run ii. sudo vim /opt/FCC_DEV0/L1/cfg/L1_NR.cfg iii. After running this command L1_NR.cfg file will open shown in the picture below iv. As mention above in the picture the highlight portion, we can change MIMO configurations here. 6. Perform following steps to modify L1_NR.cfg configuration file :-

i. Go to the insert mode by pressing i key and edit the parameter as required. ii. To save the file press ESC and type command :wq then press ENTER iii. If dont want to save file, press ESC and enter command :q! then press ENTER 3.1.4 Troubleshooting In any case if you are not able to do the ssh or getting trouble while accessing hardware then connect monitor through HDMI/VGA cable. You will get username window then enter Username as miab and Password root@123. If you get blue screen then enter ctrl+alt+f3. Enter username as miab and Password is root@123. Once the authentication done enter command ipconfig for checking the IP address. 12 Now First do sudo su and password root@123 If you want to change the IP then enter vi /etc/netplan/00-network-manager-all.yaml. Once you enter, press insert and change the IP address mention in the below picture. 14 4.UHD UPGRADE 4.1.1 Prerequesit:

1. Sub_6GHz Hardware should be connected with internet 2. Command: vim /etc/resolve.conf nameserver 127.0.0.53 change it to 8.8.8.8 save and close file. 3. Now check ping google.com its output should be like below 64 bytes from del03s16-in-f14.1e100.net (172.217.167.46): icmp_seq=1 ttl=117 time=7.05 ms Steps to upgrade UHD if your are facing error something like -:

Reading package lists... Done Building dependency tree Reading state information... Done E: Unable to locate package uhd-packages root@phluido-NUC9i9QNX:~# apt-get purge libuhd-dev Reading package lists... Done Building dependency tree Reading state information... Done You might want to run 'apt --fix-broken install' to correct these.

run this command -: apt --fix-broken install run below given command 1. sudo apt-get remove uhd-host 2. sudo apt-get remove --auto-remove uhd-host 3. sudo apt-get purge uhd-host 4. sudo apt-get purge --auto-remove uhd-host while running these commands it will ask for permission Y/n then enter Y. dpkg -l | grep uhd apt-get purge uhd-packages vim /etc/apt/sources.list deb https://ppa.launchpadcontent.net/ettusresearch/uhd/ubuntu bionic main deb-src https://ppa.launchpadcontent.net/ettusresearch/uhd/ubuntu bionic main append above two lines, sva e& close files. Now run command: apt-get update while updating it sometimes throws error for key then apt-key adv --keyserver keyserver.ubuntu.com recv-keys received keys Now again run apt-get update run apt-get install libuhd-dev uhd-host -y run uhd_find_devices its output should look like below screen shot:

4.1.2 REBOOT MEC gNB Note: In case you face the problem like that uhd is not found or you you just want to restart the hardware Run the below command for rebooting the hardware reboot -f 16 4.1.3 FCC Regulations and RF Exposure FCC Regulations This device complies with part 15 of the FCC Rules.

This is to confirm that the FCC ID: 2BASDAMTMEC20234, known as MEC, has the SDR card N310 installed, and the FCC ID: 2BASDAMTBN20233, known as HC2, has the SDR card B210 and SDR card N310 installed. SDR cards of 2BASDAMTBN20233 and 2BASDAMTMEC20234 are electrically identical when installed in an end user device. Power settings, and configuration settings are programmed identically. Therefore, the conducted licensed testing of licensed band for 2BASDAMTBN20233 can be re-used to 2BASDAMTMEC20234. The HC2s conducted test data shall remain representative of the MEC so, MEC (this model) leverages conducted test data from HC2. The enclosure and other components, such as power supply and CPU, may be different. Yours sincerely, Amantya Technologies Pvt.
