Sequoia

Sequoia is well known as the leading wireless product supplier from GPRS, GPS, Zigbee, 802.15.4 modules, to custom software to run the products. Sequoia has for some years now designed, developed and manufactured many of its own wireless products. These are used as end equipment for some customers or as OEM products for inclusion into our customers' systems. GPRS and 3G modem terminals are examples with Ethernet and micro controlled versions available. We even use our terminals in our own remote monitoring products within our Sensormetrix division. Cellular Signal strength testers for 2G and 3G networks are also popular Sequoia products.

Many companies and customers use Sequoia products for their cellular, GPS and antenna designs where we advise which products will perform the desired functionality, we help with PCB layout (or do it), supply relevant Sequoia customised software and antenna designs. In some cases we do the complete process including volume manufacture. Through the many years of experience in doing this customers know that Sequoia wireless designs work.

Our expertise in wireless technology has enabled us to not only build a broad and relevant product range, but also to provide a high level of technical support and advice to add significant value to our customer's designs.

Our antennas and matching RF cables are manufactured by our selected manufacturing partners in Eastern Europe or the Far East. This ensures a quality construction at a competitive price. Most antenna systems need RF cables internally or for connecting the antenna to the equipment - Siretta manufactures any permutation of cable with any length and connector or termination. Siretta antennas and cables are available from many distributors in Europe.
