What is the IP address, network mask, gateway?

Exchanging data between at least two computers requires a dedicated computer network has to be created. In such a network, the devices communicate using transmission media via appropriate communication protocols. Not only computers and servers can be connected to a computer network these days, but also CCTV equipment, alarms, smart home components or household appliances.

Special HDMI to IP solutions with Signal HD converters supporting HDbitT protocol

Signal HD converters of HDMI (or VGA) to IP interface allow users to transmit and distribute high-resolution (HD) signals via computer IP networks to HD-enabled televisions/monitors (with HDMI or VGA inputs). They also enable users to control the source devices from the remote locations of the televisions/monitors through the original remote controls or, where applicable, through USB devices (mouse and/or keyboard – e.g. in the case of STBs and NVRs).

Twisted-pair cables - categories, shielding, applications

Twisted-pair cables are used to transmit signals in telecommunication systems and computer networks. The most popular twisted-pair cables are composed of four pairs of twisted insulated copper wires. The twisting strongly reduces the influence of external electromagnetic interference and mutual interference between the pairs, called crosstalk. Currently, the cables are mainly used in telephony and Ethernet networks.

Yagi-Uda antennas - putting the theory into practice - tailor-made designs!

The Yagi-Uda or Yagi antenna is one of the most popular antenna designs. Despite a comparatively simple construction, it has a high gain, typically greater than 10 dBi. Yagi-Uda antennas can operate in the HF to UHF bands (3 MHz to 3 GHz), but often within a limited bandwidth around the center frequency.

Industrial switches - equipment for all conditions!

ULTIPOWER Ethernet industrial switches enable data transmission at rates of 10/100 Mbps or 1000 Mbps. Their RJ45 ports support auto-negotiation and Power over Ethernet (PoE) functions. The devices automatically discover PD devices (///Power Device///) compliant with IEEE 802.3af standard and supply power to them. This way, it is easy to power network devices located in places without access to AC lines, such as access points, IP cameras, IP phones etc. The switches have been equipped with optical converters or SFP slots for installing modules changing the transmission medium to fiber.

Twisted-pair cables - nomenclature, standards, parameters

Twisted-pair cables are used to transmit signals in telecommunication systems and computer networks. Currently they are mainly used in analog telephony and Ethernet networks. Twisted-pair cables may consist of one or more pairs. The twisting strongly reduces the influence of external electromagnetic interference and mutual interference between the pairs, called crosstalk.

Types of connectors in WLAN, GSM, 3G, LTE devices

The user of a wireless network device such as access point, wireless adapter, modem etc. who wants to buy an external antenna should know the type of the antenna connector used in the device. A multitude of solutions and slight differences in appearance mean that less experienced users can have great difficulty in choosing the antenna with a matching connector.
