A computer network or data network is a telecommunications network which allows computers to exchange data. In computer networks, networked computing devices pass data to each other along network links (data connections). Data is transferred in the form of packets.

The transmission media (often referred to in the literature as the physical media) used to link devices to form a computer network include electrical cable (Ethernet, HomePNA, power line communication, G.hn), optical fiber (fiber-optic communication), and radio waves (wireless networking). In the OSI model, these are defined at layers 1 and 2 — the physical layer and the data link layer.

A widely adopted family of transmission media used in local area network (LAN) technology is collectively known as Ethernet. The media and protocol standards that enable communication between networked devices over Ethernet are defined by IEEE 802.3.

Ethernet transmits data over both copper and fiber cables. Wireless LAN standards (e.g. those defined by IEEE 802.11) use radio waves, or others use infrared signals as a transmission medium. Power line communication uses a building’s power cabling to transmit data.

Techno Sat Comm is specialized in LAN and WLAN Campus Access Networking projects. We have successfully installed the LAN and WLAN Secured Network in Medical University at PGIMS Rohtak, In Hyundai also we have done the same LAN and WLAN Networking Installation. Instead of that we have many other well known clients For LAN and WLAN like BCCI Mumbai, National Stock Exchange Mumbai.

In Hotel Industry also we are known for our specialization, We have given WLAN solution in some of 5 stars and 3 stars properties like Rangsharda Hotel Bandra.
