Overview

SIST EN 301 215-2 V1.3.1:2003 defines the essential electrical characteristics for point-to-multipoint antennas used in fixed radio systems operating within the 24 GHz to 30 GHz band. Aligned with the European standard EN 301 215-2, this document is a key reference for manufacturers, network designers, and regulatory authorities working with fixed wireless access (FWA), digital radio relay systems (DRRS), and radio local loop (RLL) infrastructures.

A key revision in this version is the reduction of the terminal station’s minimum boresight gain in Gain Category 1 from 26 dBi to 22 dBi. This change facilitates broader equipment design options while optimizing the use of scarce radio spectrum resources.

Key Topics

• Frequency Range: Focuses on point-to-multipoint antennas operating in the 24 GHz to 30 GHz segment.
• Antenna Types: Applies to fixed beam, linearly polarized antennas for both terminal and central station use. Electronically steerable and circularly polarized antennas are not covered.
• Minimum Boresight Gain: Sets the minimum gain for terminal station antennas:
  • Gain Category 1: 22 dBi
  • Gain Category 2: 28 dBi
• Radiation Pattern Envelopes: Specifies standardized co-polar and cross-polar radiation pattern envelopes for various antenna classes to ensure consistent performance and minimize interference.
• Central Station Sector Antennas: Defines templates for sector (non-omni) central station antennas-outlining sector angles and corresponding minimum boresight gain requirements across the 24 GHz to 30 GHz band.
• Polarization: Requires all antennas to radiate a linearly polarized wave.
• Radome Compliance: Performance requirements, including gain and pattern, must be met with a radome installed if applicable.

Applications

SIST EN 301 215-2 V1.3.1:2003 is fundamental for:

• Fixed Wireless Access (FWA): Critical for last-mile broadband connections using radio links instead of traditional cabling.
• Digital Radio Relay Systems (DRRS): Used for robust microwave backhaul, enabling high-capacity network connections between base stations and core networks.
• Radio Local Loop (RLL): Supports local area coverage for telephony and broadband services, particularly in dense urban or difficult terrain.
• Frequency Coordination: By standardizing antenna parameters, this standard helps frequency planners and regulators minimize interference and maximize spectrum efficiency.
• Equipment Certification: Manufacturers use these requirements to ensure their point-to-multipoint antenna products meet regulatory standards for deployment in the 24 GHz to 30 GHz band.

Related Standards

For comprehensive implementation, reference to the following associated standards is recommended:

• EN 301 215-1: General aspects and overall framework for fixed radio system antennas (11 GHz to 60 GHz).
• EN 301 213-1: Fixed radio systems; point-to-multipoint digital radio systems in frequency bands 24.25 GHz to 29.5 GHz.
• EN 300 833: Point-to-point fixed radio system antennas in the 3 GHz to 60 GHz band.
• ETSI EN 301 126-3-2: Conformance testing for point-to-multipoint antennas, including definitions, requirements, and test procedures.

By adhering to SIST EN 301 215-2 V1.3.1:2003, companies contribute to the reliable and interference-resistant deployment of high-frequency fixed wireless networks, meeting both technical and regulatory needs in modern telecommunications.
