Question 1

What does Radio Link Aggregation (RLA) enable in Ericsson MINI-LINK microwave backhaul?

Accepted Answer

Bonding multiple radio links to increase total throughput beyond a single link's capacity

Answer

Routing IP packets over satellite fallback links

Answer

Reducing the frequency coordination workload

Answer

Enabling massive MIMO on microwave frequencies

Question 2

In Ericsson MINI-LINK terminology, what does an 'all-outdoor' configuration mean?

Accepted Answer

All radio, modem, and switching functions are integrated into a single outdoor unit requiring no separate indoor equipment

Answer

The system must be installed in rural areas only

Answer

The system operates exclusively above 20 GHz

Answer

Only the antenna is outdoors while all electronics are indoors

Question 3

What is the maximum modulation order commonly supported by modern Ericsson MINI-LINK high-capacity links?

Accepted Answer

4096-QAM

Answer

64-QAM

Answer

256-QAM

Answer

1024-QAM

Question 4

How does XPIC improve spectral efficiency in an Ericsson MINI-LINK co-channel dual-polarization deployment?

Accepted Answer

By allowing simultaneous use of vertical and horizontal polarizations on the same frequency channel

Answer

By doubling transmit power on each polarization

Answer

By dynamically switching between frequency bands

Answer

By compressing IP packet headers before transmission

Question 5

Which standard governs Synchronous Ethernet (SyncE) messaging used for frequency synchronization in Ericsson MINI-LINK?

Accepted Answer

ITU-T G.8264 (ESMC — Ethernet Synchronization Messaging Channel)

Answer

OSPF area synchronization

Answer

BGP community attributes

Answer

MPLS-TP signaling

Question 6

In microwave backhaul, what is the role of QoS traffic prioritization?

Accepted Answer

To ensure latency-sensitive traffic such as voice and signaling is forwarded ahead of best-effort data

Answer

To block unauthorized users from accessing the network

Answer

To increase the modulation order of the radio link

Answer

To manage IP address allocation across backhaul nodes

Question 7

Which standard or set of standards defines Ethernet OAM (Operations, Administration, and Maintenance) used in Ericsson microwave networks?

Accepted Answer

IEEE 802.1ag (CFM) and ITU-T Y.1731

Answer

IEEE 802.3ab (1000BASE-T)

Answer

SONET/SDH G.803 framing

Answer

ITU-T G.652 fiber characteristics
