Microwave Solution

LOS Technology is working with Neratel and solutions provider in Bangladesh. LOS is offering:


The solution for cost-effective deployment of low and medium capacity transmission networking. The CompactLink is fully a featured, microwave radio system for the global telecommunications market. The CompactLink operates in the frequency band 13, 15, 18, 23 and 38 GHz, and with data rates of 2, 4, 8, 16 E1 or E3+E1. ANSI versions operate with data rates of 2, 4, 8, 16 DS1 or DS3+DS. It is designed for transmission of voice, data and video traffic. Standardized data rates (E1/T1) and frequency bands are controlled by international organizations (FCC, ITU-R, ITU-T, ETSI). The IDU is frequency independent and fits into an ETSI rack or a 19″ rack. Alternatively, it can be used as a stand-alone unit. Both ETSI and ANSI transmission capacity requirements are supported.

– ETSI: 2E1, 4E1, 8E1, 16E1 and E3+E1.
– ANSI: 2DS1, 4DS1, 8DS1, 16DS1 and DS3+DS1.

In the unprotected configuration, one 1RU IDU is required and in the HSB configuration, one 2RU IDU is required. The Nera CompactLink ODU integrates transceiver and branching in one unit. For the HSB configuration, an outdoor RF hybrid is included to combine the two ODUs. The Nera CompactLink ODU is capacity independent, frequency synthesized and has adjustable T/R spacing. For unprotected configurations, the IDU and ODU are connected with a single coaxial cable (maximum 300 m). In the HSB configuration, the IDU and ODUs are connected via two separate coaxial cables. With the built-in SNMP agent, the Nera CompactLink – PDH Microwave Radio is capable of functioning as a Network Element (NE) in a managed transmission network. Management and supervision of the Nera CompactLink can be performed in various ways, from simple alarm monitoring to standardized management via SNMP. For network management and operation, the Nera Element vieW – Network Management System (NEW NMS) can be delivered. An integrated antenna/mount solution can be delivered with antennas having diameters of 0.3 m, 0.6 m or 1.2 m. When system performance requires higher antenna gain, independently mounted, larger antennas can be used.

The new comprehensive family of compact SDH long-haul radio Nera InterLink is the new generation of SDH radio-relay transmission equipment in the 4 to 11 GHz frequency bands. The InterLink family is ideally suited for long distance high capacity communication solutions. The new Nera InterLink provides more compelling reasons than ever to choose microwave radio for trunk networking environments. Naturally, it offers the outstanding generic benefits of microwave radio networks. It is considerably faster to plan and install compared to fibre optic cable. Overall, the Nera InterLink enables an uncompelled network rollout speed. Incorporating the latest generation electronics the Nera InterLink is also an inherently reliable solution.

Today’s society depends more and more on telecommunications and microwave radio offers secure and reliable solutions. Radio networks do not suffer from the long periods of outage that can be experienced when a fibre optic cable is cut. The Nera InterLink is therefore often chosen to protect mission critical communication services. Furthermore, it is a highly versatile modular system covering multiple applications, as well as being easily reconfigured and upgraded.
