ZOOM-N-UMTS 3G/UMTS Socket Modem Equivalent & Substitute Parts

Part Overview

The ZOOM-N-UMTS is a 3G/UMTS socket modem manufactured by Siretta Ltd, designed for RF communication across multiple frequency bands including 800MHz, 850MHz, 900MHz, 1.7GHz, 1.9GHz, and 2.1GHz. The device supports GPRS protocol with dual interface connectivity via RS-232 and USB, delivering maximum data rates of 14.4Mbps with a receiver sensitivity of -108dBm. This product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ZOOM-N-UMTS is determined by strict alignment with the following critical parameters:

• Modulation Protocol: GPRS support is mandatory for functional equivalence
• Frequency Band Coverage: Substitute parts must support the complete set of bands (800MHz, 850MHz, 900MHz, 1.7GHz, 1.9GHz, 2.1GHz)
• Interface Connectivity: Both RS-232 and USB interfaces must be present
• Data Rate Performance: Maximum data rate must meet or exceed 14.4Mbps
• Receiver Sensitivity: Sensitivity specification must be -108dBm or better
• Compliance Status: RoHS compliance is required for regulatory equivalence

No substitute parts meeting all specified parameters are currently available in the provided dataset. Any future substitution must satisfy all parameters listed above without exception.

Engineering Selection Recommendations

Given the obsolete product status of the ZOOM-N-UMTS and the absence of documented substitute parts meeting all specified parameters, component selection must be based on the following engineering criteria:

• Compliance Verification: Any alternative must maintain RoHS compliance status to ensure regulatory alignment with the original design
• Protocol Compatibility: GPRS protocol support is non-negotiable for system integration
• Interface Requirements: Dual RS-232 and USB connectivity must be preserved to maintain compatibility with existing host systems
• Performance Specifications: Receiver sensitivity and data rate specifications establish the minimum performance threshold for functional replacement

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the ZOOM-N-UMTS?

A: A substitute must support GPRS protocol, cover all six frequency bands (800MHz, 850MHz, 900MHz, 1.7GHz, 1.9GHz, 2.1GHz), provide both RS-232 and USB interfaces, achieve 14.4Mbps data rate, deliver -108dBm receiver sensitivity, and maintain RoHS compliance.

Q: Why are no substitute parts listed?

A: The provided dataset contains no parts meeting all required parameters. Substitution requires exact alignment across protocol, frequency coverage, interface type, performance metrics, and compliance status.

Q: Can I use a modem with partial frequency band support?

A: No. The ZOOM-N-UMTS supports six specific frequency bands. Any substitute must support the complete set to ensure operational compatibility across all intended deployment regions.

Q: Is RoHS compliance mandatory for substitution?

A: Yes. The original ZOOM-N-UMTS is RoHS compliant. Regulatory equivalence requires substitute parts to maintain this compliance status.

Q: What if I only need RS-232 or USB, not both?

A: The ZOOM-N-UMTS provides dual interface capability. Substitutes must maintain this dual-interface specification to preserve design flexibility and system compatibility.
