4G/LTE Modems

ZETA 4G Modems

ZETA is a great modem for systems that just need to get online with a 4G connection.   ZETA operates with a wide input voltage range making it ideal for vehicle applications.  In addition 5 GPIO lines are available to remotely monitor or control.

ZOOM 4G Modems

The ZOOM modems are a range of socket modems designed for 2G/3G/4G and with a fantastic feature-set.  ZOOM is designed to be integrated with your own designs and includes headers to make it easy to added connectivity to your product.

ZULU 4G Modem

The ZULU range of 4G /LTE modems are amongst the most advanced and capable modems available today. The range is available as two main versions - with or without GPS. Further options include a 2000mAh battery and an upgrade of flash memory to a total of 128Mbit. The ZULU range can be used as a simple modem, or with application software within the UMTS module. But its real strength, for the user, is as a comprehensive computing platform using its ARM Cortex M4 32bit processor connected to the 4G/LTE engine - all in one package. The ZULU design has been extensively tested and represents amazing value as a 4G/LTE connected powerful 32bit computing engine.


4G / LTE Routers


MICA Series 4G Routers

Its compact small size design, enables the MICA  Router to easily be embedded into other equipment or systems. With the GPS option, the MICA router is ideal for fleet tracking or access management.


QUARTZ Series 4G Routers

The QUARTZ 4G Routers have two SIM slots for applications which require an always-on connection.  The router can intelligently switch to an alternative network if the primary one becomes unavailable.  The QUARTZ router range has a dual SIM facility, RS232/ console port and 3 x I/O ports as standard. It also has a number of standard options, such as WiFi, GPS, 1 x WAN + 1 x LAN interface etc making the QUARTZ range one of the best to specify exactly your specification of router for low MOQs.


4G / LTE Antennas

We now have a growing range of 4G/LTE antennas in most mounting styles including embedded types. Our 4G antennas are equally competent at 3G frequencies making them future proof as to whether you will move from 3G to 4G bands as they become available or your project calls for it.

All of the 4G antennas also are good performers on the Quad band GPRS frequencies but the top gain is at 3G and 4G frequencies.

Extend your reach with Siretta quality, low-loss RF cables

Acquiring RF signals in poor reception areas (2G/3G/4G), short range wireless communication (line of sight for 433 and 868 MHz) or WifI connection in large buildings will require high gain antennas placed as high as possible to get the best reception. Problem is that the longer the cable length is from the RF equipment to the antenna, the higher the losses and consequently poorer reception. RG174 and RG58 are standard cables that everyone use for RF work, however the losses per metre escalate rapidly the higher the frequency goes. Antennas with cable lengths of 10M, 15M or 20M will suffer considerable loss over the length. It means that a more powerful transmitter and /or a more sensitive receiver is required. This all comes at a price in one way or another. Better to not have the losses there in the first place. Standard RG58 cable has an approximate loss per metre of 1dB at 2.5GHz - Wifi and Euro 4G frequencies. Bear in mind that a loss of 3dB of signal is actually halving the signal strength it is easy to see why systems are not very sensitive if they have long and standard cables to the antenna. Now take the LLC200 low loss RG58 equivalent it has a solid copper core and 2 levels of shielding and special connectors to accommodate the cable. It has a 0.55dB loss per metre at the same 2.5GHz frequency. Bearing in mind the logarithmic nature of measuring in decibels the signal arriving at the end 20M of RG58 cable at 2.5GHz is about 0.07% of what went it to the cable. Alternatively, using the LLC200 cable the signal arriving at the end of the cable is around 12% of what went in. 0.07% versus 12% is a massive difference in signal strength. This is the case for Siretta\'s low loss cable range! Siretta’s low loss extension cables provide the best solution in minimising losses and giving the required RF signal for a successful and continuous wireless connection. Generally speaking low loss cables are not very available as a stock item, however at Siretta we have a complete range of cable lengths and connector styles from stock or very short lead time. Available in cable lengths from 5m to 20m with a vast number of connector combinations, including, SMA, FME, N-Type and TNC etc. Look for the white cable marker telling that it is a Siretta quality cable, its part no. and length.....
