Comba Telecom Introduces New Antennas to Solve 5G Infrastructure Challenges

Comba Telecom has released new Super Multiband and TDD+FDD Integrated antennas to assist the macro network evolution into the 5G era.

5G networks are expected to enable seamless and real-time connectivity for Internet-of-Things (IoT) and machine-to-machine (M2M) communications to raise living standards in a smart environment. However, telecom operators are facing challenges while planning for the full implementation of 5G infrastructure: network capabilities, CAPEX / OPEX and cell site overload and acquisition issues. To have efficient utilization of existing technologies and cell sites, the industry believes that LTE and 5G networks will coexist for a number of years. To keep pace with the market change, Comba Telecom has developed a series of tower top solutions for building a convergent network for LTE-based and 5G systems.

The Super Multiband Antenna and TDD+FDD Integrated Antenna are the latest 5G-oriented solutions of Comba Telecom. The antennas are designed to accommodate multiple systems in an integrated chassis, enabling high-quality convergent network. The innovative design helps operators minimize the overall antenna counts on tower top, simplify site deployment and optimize network efficiency while adding 5G massive MIMO antennas to the existing cell sites. The antennas will be invaluable for operators to enhance both network coverage and capacity in a highly efficient way. Key features of the antennas are as below:

Super Multiband Antenna

  • Supports ultra-broadband from low frequencies to high frequencies
  • Multiple ports ultra-broadband platform supporting all sub 3G 4T4R
  • 2LB+4HB arrays SBS design @498 mm width
  • Up to 8x8 MIMO solution for 1800, 2100 or 2600 MHz
  • Supports 700 or 800MHz 4x4 MIMO
  • Extends to 3LB and more HB ports with integrated diplexer
  • Greatly reduces number of antennas compared to traditional multi-band antenna

TDD+FDD Integrated Antenna

  • Integrated FDD and TDD arrays in a single radome
  • Multiple network integration: supports multiple TDD and FDD frequency bands
  • Two ultra-low bands 4 ports + three ultra-high bands 6 ports + one TDD 9 ports
  • 4x4 MIMO solution for 700, 800, 1800, 2100 or 2600 MHz
  • 2x690-960/1427-2690/2x1695-2690/3300-3800 MHz
  • Greatly reduces number of antennas compared with separate TDD and FDD antennas

Comba Telecom had showcased the antennas along with its other macro network, 5G, facial recognition and analysis, in-building wireless system, and smart city solutions at MWC 19 in Barcelona last month.
