Project Management

Presales consultancy

Himtel's experienced presales consultants are trained to analyze and advise a client in order to help the client make the best possible choices. Our consultants evaluate a business model and help the client develop a plan to meet those strategic goals.

RF Planning & System Dimensioning

Himtel’s mission is to empower the deployment and optimization of wireless technologies: reducing complexity while improving network performance. Our specialized experience and services enable our clients to excel in Radio design, Cell planning and Mobile Network Optimization. Our design for cellular and wireless networks ensures usage of fewer sites, maximum coverage, easy and faster deployable network and low installation costs.

We plan the most cost effective deployment of new radio base stations, cell sectors, and overlay technologies. Some of the steps involved are as follows:

  • Nominal planning using Aircom Tool
  • Determination of BTS site location (coordinates)
  • Determination of BTS configuration
  • Determination of Tower height, Antenna height
  • Line of sight check for Microwave Radio
  • System dimensioning of BSC/MSC (Trunk, E1, Cabinet, Rack)

Site Survey and Acquisition

This activity is start up activity of the site build up. Identification and acquisition of site within search ring with legally cleared and competitive rent is prime objective of site survey and acquisition team.

  • Based on nominal planning coordinates, we carry out survey, locate or relocate the site
  • Double-check/Recheck or confirm line of site with Mirror test with planning team
  • Confirm site location for GBT or RT Tower
  • Negotiate with landlord or VDC or municipality or Forest dept to acquire the site
  • Negotiate site rental – price, payment terms based on Telco guidelines
  • Sign the contract

Civil Works & Tower Erection

Civil works is the installation of the infrastructure which will house the electrical cables and equipment including civil survey of building/ground sites, layout drawings, structural suitability study for building sites and foundation design preparation and tower erection.

Installation & Commissioning

Himtel understands the value and significance of quality installation, pathing and testing of GSM and Microwave technology. Telco equipment installations require experienced engineers/technicians that are qualified and trained in state-of-the-art testing equipment for prompt set up and optimal performance. Himtel employs trained professionals in industry best practices to accommodate each vendor’s own specifications and requirements for seamless telecommunication equipment installations.

Due to the rapid growth in the field of telecommunication, sites enhancement and modernization for the purpose of sites reconfiguration, enhancing coverage or upgrading, Himtel has developed a full fledged suite of I&C services that caters to the whole country. Services vary from initial installation, systems modification/replacement to complete site reallocation. To date our teams of highly trained and certified engineers have successfully installed and commissioned many sites with diversified geographical flavours across the various development regions of Nepal.

These works include:

  • Site Installation: Civil Work, Equipment Installation, routing and Integration
  • Sites Reallocation: Dismantling and installation in of sites and MW links in new sites and different location
  • Site Dismantling: Unfixing cabinets, MW links and cables
  • Site Survey: Identifying numbers of cabinets, types of batteries and site configuration & routing
  • Site Acceptance: Ensuring quality of site, cabinet fixations, connections and proper isolation
  • 3G Expansion: Increasing connections and replacing old ones
  • MW Links I&C: Complete Installation, Commissioning and alignment of MW links

After identification of site, Himtel has the expertise to proceed with installation and commissioning of a Base Transceiver Station (BTS). BTS is a piece of equipment that facilitates wireless communication between user equipment (UE) and a network. UEs are devices like mobile phones (handsets), WLL phones, computers with wireless internet connectivity, WiFi and WiMAX devices and others. The network can be that of any of the wireless communication technologies like GSM, CDMA, Wireless local loop, WAN, WiFi, WiMAX and others.
