The advantage of using wireless data transmission module... Data transmission can be simply divided into two major types: wired (including the installation of optical cables, cables or leased telecommunication lines) and wireless (including the establishment of dedicated wireless data transmission system or the borrowing of CDPD, GSM, CDMA and other public network information platforms).     In...

The structure of 4G DTU The main function of DTU is to transmit data from remote devices back to the background center via wired/wireless. Different data transmission modes of DTU include all-network-connected DTU, GPRS DTU, WIFI DTU, CAN DTU and 4G DTU. Today, we will have a look at the structure and work flow of DTU.   To complete...

4 reasons why 4G hasn’t scale up in India
One,Challenges for deploying 2300 MHz TD-LTE: The spectrum band licensed for BWA in India (TD-LTE on 2,300 MHz) has only been deployed in around 20 countries including Hong Kong, Australia and South Africa; the band lacks ecosystem support, device choices and network scale. Of the overall 1,000 devices launched by manufacturers for LTE, only 100 are suitable for the mode licensed in India. As a result, Indian operators have had to consider offering LTE services to a Wi-Fi router which in turn connects Wi-Fi-ready devices. The band is also weaker in offering in-building coverage compared to other modes of LTE.
Two, Better backhaul: Backhaul connections currently lack the coverage and quality required to render 4G services effective. Without the backhaul service to carry data at the same speed, the benefit of the 100 mbps connectivity offered by 4G cannot be realised by the end user. Over the last few years, Indian operators have invested heavily in rolling out fibre; we are now beginning to see scale and agreements falling into place.
Three, Combining data with voice: The advantage of offering super-high-speed data connectivity bundled with mobile voice is that the 4G service needn’t have to compete directly with fixed alternatives on price alone. Telecom regulations now allow an entity to hold a universal access licence to offer mobile voice. So, provided the BWA player has access to voice spectrum, it can now bundle high speed data and voice together.

Four,Capital constraints: A number of operators have put priority on deploying 3G first, due to capital and management constraints. And, in general, India’s capex to sales ratio has come down to 12-14 percent, while it is 22-25 percent for other emerging Asian countries such as China.
