Introduction to the Course.
Explore wired and wireless transmission types, from optical fiber and copper ethernet to microwave links, with single-mode and multi-mode fiber, high speed, high bandwidth, and half-duplex and full-duplex.
Explore the mobile network architecture enabling device-to-device communication from the nearest BTS to the MSC, highlighting call routing, call control, and quality control.
Explore how mobile site components—BTS, indoor and outdoor units, power and cooling systems, alarms, and microwave links—connect to route calls from BS antennas to the BCC.
Explore how to distribute mobile network infrastructure across a city using hexagonal segmentation, full site deployment with BTS and microwave links, and cascaded connections to the BCC.
Understand microwaves, electromagnetic radiation from 1 m to 1 mm wavelengths (300 MHz to 300 GHz), powering wireless links between mobile network sites for radar, medical, and satellite communications.
Install and configure the indoor and outdoor microwave link units, connect the IF cable, and monitor performance with the IDU, RAW, and DISH antenna sections across common bands.
Align microwave link antennas for a clear line of sight by tuning azimuth and elevation per the link design, then verify with avometer readings, SNR, and RSL targets.
Assess factors shaping microwave link signals, including site proximity to water, rain, and power lines, and determine elevations and line of sight to route traffic to BECC.
Explain the 1 plus 0 microwave link, with one rau, one microwave dish antenna, one idu, and one if cable, and compare its low cost to the lack of backup.
Examine microwave link configuration one plus one hot stand-by, using two RAUs, two IFP cables, and site couplers to secure traffic, enable fault tolerance, and note higher costs.
Learn how XSPEC cross-polarization interference cancellation expands microwave link capacity with 2+0 configurations, CCDB dual polarization, branch alignment, and XBI testing for isolation between branches.
MBL microwave links combine traditional microwave and E-band links into a single system using a dish, a coupler, and multi-band channels to boost capacity and reliability.
Apply space diversity to microwave links to reduce multipath fading and improve reliability by using main and diversity antennas that receive the same signal and select the best.
Explore the ags-20 indoor unit with 2 or 4 IF radio interfaces, enabling multiple chains and directions toward different sites, plus two serial ports for 16 e1s and LAN ports.
Master two local login methods to the SIA-AGS-20 node: login via the LCT port with 192.168.0.1 and admin admin, or via LAN3 with 10.250.30.5 and laptop 10.250.30.4.
Configure SEIA AGS-20 link by selecting link type and creating or removing links, set bandwidth, modulation, frequency, power, and ACM profiles; configure ports and vlans from LAN 1 to OduA.
Back up AGS-20 node via ftp using cssct, specify the laptop IP and backup path, and save a .bk file; restore requires the same path, software release, and hardware version.
Upgrade AGS-20 software on nodes; switch software between bench 1 and bench 2; upgrade boot and abbl for rows using SCT Craft FTP to align row a with row p.
Explains SEIA E-Band nodes Alpha 80 HD and HDX, their electrical and optical connections, 1+0 and 2+0 configurations, and how to access and manage via ports and console steps.
Examine how to perform a local login on the SIAE e-band within microwave links for mobile networks.
Analyze the SIAE e-band software upgrade and its role in advancing microwave links for mobile networks.
Explore Huawei RTN nodes for microwave links in converged networks, showcasing high capacity transmission, flexible configurations, and protection schemes across the ten 980, 950, 910, 905, and 380 series.
Configure the Huawei RTN microwave link by aligning node settings, enabling ports, and setting channel bandwidth, TX frequency, modulation, and power, then establish VLANs and OSPF.
Learn to back up, restore, and upgrade Huawei RTN using the DC software and FTP transfers. Configure the laptop IP and partition E to manage backup files and configurations.
