Companies often need WLAN ( WIFI ) in the warehouse or even in the office. The prerequisite for complete WLAN coverage is an optimal number of access points. This is achieved by WLAN illumination. Based on floor plans we estimate the placement of the access points. On site we check and optimize the positions of the access points with measuring instruments. Finally, you will receive a recommendation for the equipment with access points.

Demands on security and speed of WLAN networks are constantly increasing. For your network solutions, we offer you not only WLAN illumination but also appropriate access points - whether for your office, warehouse or company premises. We take care of delivery, assembly and installation of access points and switches.

A company expansion required a new backup strategy and a new IT infrastructure for two server rooms ( VMware and SAN storage / backup and recovery solution ). To optimize administration and communication, all subsidiaries were connected to the data center and an IT migration to current versions of domain and Microsoft Exchange Server was carried out.  >> order notification

Due to expiring manufacturer warranty and reaching the performance limit, the procurement of new hardware and IT migration to current systems became unavoidable. In the implemented IT migration concept, old systems were partially reused, new systems were procured and Windows Server 2019, Exchange Server 2019 and all relevant data were migrated with minimized and planned downtimes.

As a certified Fujitsu partner with 30 years of IT competence, SIGMA is at your side with IT system support, IT monitoring and a hardware repair service. We replace defective components even after the warranty has expired and take care of spare parts procurement, installation and functional testing.

As part of a concept for modernizing the IT infrastructure, servers (host server, central storage unit and backup server) and a tape library were installed. Furthermore, an IT migration was carried out for the domain ( 2003 to 2008 ) and for the Microsoft Exchange Server from version 2003 to 2010. >> reference report

Based on IT system support, we create a technical documentation with an overview of your IT system network (server and storage), RAID, data storage, network configuration and a list of all IT systems including name, IP address, function and serial number. We document your LAN network structure including subnets and your configurations (e.g. Exchange, firewall, anti-virus software, email archiving and data backup).

Knowledge transfer is very important to us. In training courses and workshops, preferably on site at the customer's premises, we provide IT managers and administrators with the latest knowledge, e.g. on how to use new anti-virus software, the backup system or the latest version of Microsoft Office.

Due to the growth of the company, a roll-out of 125 Fujitsu clients (high-quality notebooks, high-performance mini workstations, small form factor desktop PCs and monitors) was carried out. SIGMA took over configuration, installation, roll out planning, coordination with software providers and creation and installation of images for the departments. After delivery, integration into the existing IT infrastructure took place.

Due to growing IT system requirements and to ensure a smooth running IT system, a comprehensive renewal of the clients was recommended.
In accordance with the technical and budget specifications of the customer, 155 suitable PCs and notebooks from Fujitsu were offered after compatibility and configuration checks. Despite a subsequent change in the number of units, an attractive price was granted.

In the context of a change in the IT infrastructure at CEFEG, a data backup concept was defined for the realization of a manipulation-free and audit-proof email archiving. It was decided to use the email management system of REDDOXX and SIGMA Chemnitz as competent project partner. >> reference report

Growing amounts of data and partly outdated hardware required an increased administrative effort. Even IT failure safety no longer met the requirements. This made the renewal of IT infrastructure urgently necessary, which required a well thought-out IT concept. In this concept, system requirements and dimensioning of necessary IT components were analyzed and based on this, the course of the project was determined. Subsequently, the IT project was implemented by SIGMA Chemnitz. >> reference report

We also offer our IT maintenance customers IT network solutions and IT system support outside Chemnitz. Increasing performance requirements and a growing number of users required a new procurement of PoE switches. LANCOM switches were chosen to meet these requirements. SIGMA's service package included the procurement and installation of the switches and a WLAN configuration.
