Cellular Signal Analysers

The Siretta range of signal analysers are sophisticated yet easy to use from the SNYPER Handheld solutions to the embedded remote SENTRY. Depending on which solution you choose, 2G / 3G / LTE and LTE Cat M / LTE Cat NBIoT cellular technologies are covered. The SNYPER is a handheld, battery operated unit and can operate for several hours between charges (depending on use). It analyses all cellular signals from any network at any particular site being surveyed and displays the results in a simple and easy to understand format.

The SENTRY is a remote unit can be left unattended to conduct surveys in a fixed location and automatically saving them. Four types of survey can be performed: a “FULL” survey (4G, 3G and 2G combined), 4G/LTE only, 3G/UMTS only & 2G/GSM only. The SENTRY also has the capability to monitor cellular registration time, socket connection times, TCP/IP registration, Ping time and upload-download speed testing.

Technology Coverage
– Global 3G / UMTS with 2G / GSM Fallback- European LTE 3G / UMTS and 2G / GSM
– Asia Pacific LTE and 3G / UMTS
– North American LTE and 3G / UMTS
– Global LTE Cat M and LTE Cat NBIoT

Why would you use a SNYPER or SENTRY?
Surveying a Cellular network is a powerful way to allow engineers, project managers, developers to analyse, troubleshoot, and optimise IoT applications. By having a comprehensive view of network performance by capturing  network traffic, signalling, and radio frequency (RF) data that can determine the correct cellular application that is optimised for you.

Diverse Antenna Solutions

Antennas are a fundamental component of any wireless RF solution. Both, the most complex and the simplest wireless RF applications rely on antennas for end to end communication. The quality and performance of the antenna is critical to the correct operation of any wireless system, and it pays to specify it wisely.

Technology Coverage
– Global Cellular Bands (2G / 3G / 4G / LTE / Cat M / NB IoT / 5G)
– WiFi / BLE (2.4GHz / 5.8GHz) / Sigfox / LoRa / ZigBee
– GNSS Positioning (GPS / GLONASS / Galileo / BeiDou)
– Global ISM Bands (151MHz / 173MHz / 433MHz / 458MHz / 868MHz / 915MHz / 2450MHz)

Common Applications
– Enhanced Cellular Performance
– WiFi Linked Drones
– Solar Farm: ‘Panel Data Collection’
– Smart Energy Meters
– Sensor Monitoring and Data Collection
– Combined Antenna Technologies

RF Cable Solutions

Siretta coax pigtail assemblies are made from high quality components and assembly methods to control VSWR and Return Loss. Two cable types are available, the smaller and more flexible 1.13mm and standard RG174. Patch cables are typically used for machine to machine interconnections and the low loss cable type is suitable for good signal strength links. Extension Cables are made from high quality components to ensure signal loss is reduced to a minimum.

Technology Coverage
– Assemblies supporting technologies from 100MHz up to 6GHz
– 1.13mm
– RG174 / RG174 Low Loss
– RG58 / RG58 Low Loss

Common Applications
– Enhanced Cellular Performance
– Improved RF Link Budget
– Low Loss Cable for Long Cable Runs
– Improved Options for Device Placement
– Reduced Energy Usage
– Multiple Connection Options

RF Adapter Solutions

Siretta RF Adaptors are used to connect different configurations of cable termination together and to offer the ability to swap out or change the length of an RF link. Siretta stock a large range of adaptors for most of the common industry standard configurations used in the industrial environment. To improve network signal quality for antennas, they can be positioned separately to the connected device using a magnetic base. Surge protectors are used in industry to protect connected devices from destruction from lightening strikes when antennas are used externally.

Technology Coverage
