Digital multichannel radio extension RT-300

It is intended for transfer from 15-oe up to 120-oe user's channels and Internet on a radio channel on distance up to 40 km, with group speed 2 mbps.

Consists of a digital radio extension of group use "RT-300" and user's multiplexers of a series "IKM-6A" and "MC-115T."

Provides a fast and effective way of maintenance with communication and Internet the removed settlements at absence to them of communication lines and the organization distributed integrated (oaeaoiiey+aaiiua) departmental networks.

The Digital radio extension of group use "RT-300" this is analogue RRE " R-6/E1 ", transferred in strips of frequencies of 307,5-308,0 MHz and 343,5-344,0 MHz.

1. Reception of frequencies is made not in the main federal radio-frequency center, and in local (the regional radio-frequency center) with reduction of terms on reception of radio frequencies. The decision of the given question has removed the basic problem arising at operators if necessary of application smol chennel RRE for the organization of radiocarrying out of user's capacity or organization magisterial network.
2. Features of distribution of radiowaves in a range allow applying of 300 MHz "RT-300" at absence of direct visibility that excludes necessity of construction of mast constructions which conducts to increase of cost of projects.
3. Low cost of a digital radio extension "RT-300" and terminal multiplexers entering into its structure provides the cost price of one number in 5 thousand rbl. That becomes very attractive moment for realization of various programs on installation of telephones of village.
