Telecom turnkey solution providers backed by world class manufacturing facilities.
O ICOMM offers a complete range of products & solutions on WiMAX, optical transmission, Radio Transmission & Turnkey services from Telecom Network Planning and Design to Operations & Maintenance for GSM, CDMA Networks and Defence Communications.
O ICOMM’s expertise in Project Management, RF survey, Telecom Tower Design of GSM & CDMA Towers, Site Leasing & Acquisition, Fiber Optic Networks, Interactive Mobile solutions, Telecom Shelters, Engineering services and O&M.
WiMAXO WiMAX - Worldwide Interoperability for
Microwave Access (WiMAX).O Wimax provides higher speed connection
up to 8 Mbps over the area of 15 miles.O There is no need for line of sight
connection between subscriber terminals and the base station in WiMAX technology and it can support hundreds if not thousands of subscribers from a single base station
O It is also specified in 802.16 standards that it will supports low latency applications such as voice, video, and Internet access at the same time.

WiMAX vs. Wi-Fi
O Wi-Fi and WiMAX are analogous to the difference between a cordless phone and a mobile phone.
O WiMAX coverage is about 30 miles and Wi-Fi coverage is very limited to some small area.
O WiMAX architecture is design to make possible metropolitan area networking (MAN) Wi-Fi is providing only local area networking (LAN).
O Wi-Fi - 802.11, WiMAX- 802.16O WiMAX has greater QoS over Wi-Fi
WiMAX architecture O The WiMAX architecture can be
divided into easily into three components for easy study.
•CPE•Antenna and BTS station•ASN gateway
RF Survey
O Purpose of Survey•The ultimate goal of RF survey is to determine the coverage requirement areas throughout a facility or city area. •Physical visit to design perfect coverage providing point in terms of coverage aspect.
RF Planning ProcessO Understand customer requirements for network
coverage and capacity.O Procure digital maps and antenna patternsO Get site information with current antenna height,
locations, tower height etc..O Run preliminary RF simulation using above
information create Frequency plan and run interfaces analysis.
O Conduct RF survey to collect actual site data.O Optimize the preliminary design by incorporating
accurate heights; azimuth's and tilts in design obtained the field data.
O Generate the site database for deployment.
O After the survey is done the installation of the antennas and the BTS station are done.
O The onsite components are:O AntennaO ODUO BTS station.
O Outdoor unitO The purpose of the ODU is to provide a
connectivity between the GPS antenna and the IDU which is in turn connected to the BTS station.
O 3 ODU’sO 3 Polarized antennasO Power cableO GPS cableO GPS antennaO Optical cable
Back Haul Connectivity and Types
O There are about five different types of backhaul techniques as required by BSNL
O A: Dark FiberO B: 8E1 ConnectivityO C: STM1 ConnectivityO D: GE Optical (GE Electrical SFP
interchangeable)O E: FE Optical (FE Electrical SFP
interchangeable)
CUSTOMER PREMISES EQUIPEMENT (CPE)
O Basically there are three types of CPEs used by customer:
1) Indoor CPE 2) Outdoor CPE 3) USB dongle
