$\"\"$ MUMBAI: Swedish telecom equipment maker Ericsson<\/a> is working on a fourth-generation technology that allows communication services to move seamlessly across frequencies and technology standards and may help operators overcome restrictions from frequency shortage.
\n
\nSuch a technology will over opportunities for spectrum-starved Indian operators, especially those holding multiple frequencies. One of the major beneficiaries could be Reliance Jio Infocomm, the Reliance Industries’ unit that has airwaves in the 1800 Mhz and 2300 MHz bands and yet to launch services.
“Operators in India are challenged for spectrum, but as a result of it comes some of the best technology innovations,” Arun Bansal<\/a>, the company’s radio business unit head, told ET in an interview.
\nEricsson’s technology allows a call to be completed in different bands: a caller can upload his voice onto the network in one frequency and receive the response in another. It is not possible at the moment – for instance, if the caller’s phone is using 900 MHz band to upload the voice, it will receive the respondent’s voice in the same frequency. Ericsson’s technology is already out of the lab and the company is now working on it with chipset makers.
Lower frequencies reach farther, while higher ones spread wider in an area and so are better suited to serve more customers in that area and offer fast data services. The advantage of the new technology<\/a> is that operators can deploy coverage to a larger area using the lower band as that would cost less, and use the higher band for augmenting capacity. The device will remain connected to the network in both bands.
\nA successful mobile deployment using just the 2300 MHz band can be twice as costly as 900 MHz, say experts, mainly because the higher frequency band requires more towers and antennas to take the signal to a large area, compared with the lower band.
\nReliance Jio has airwaves in the 2300 MHz band, the only one in the country to have the 4G band everywhere. But it has been dragging its feet on a 4G launch for over four years now, fearing that the lack of an ecosystem and devices for the 4G technology would play spoilsport. Earlier this year, the company acquired airwaves in the 1800 MHz band, and was pegged to launch services on two separate standards of 4G. If it adopts Ericsson’s technology, the company could reduce cost by deploying both bands to offer services.
\nThe same also holds true for Bharti Airtel, whose 4G launch in the 2300 MHz band across four major cities has been admittedly a slow starter. Globally around 50% of nearly 300 networks on LTE, a 4G technology, are built on the 1800 MHz band, Bansal said. The rest are evolving mostly on lower bands, barring China that is using 2300 MHz.
\nIndia is unlikely to skip a technology generation and will first experience the contours of 3G before adopting the next generation technology, Bansal said. “The handover from 2G to 4G technology is not smooth. If you see the ecosystem the 3G terminal (cellphone) is available at $50, for 4G that is still some time away.”
\nTo address coverage issues, Bansal believes the deployment business models are likely to change. For example, building owners may start deploying in-building solutions and charging for it in rentals, he said.
\nAccording to him, having more operators in India does not translate into higher sales for equipment vendors. “What finally matters is the usage, because the capacity still remains the 1.2 billion people. So whether it is three operators or seven operators, capacity is being built for just those people.”\n\n<\/body>","next_sibling":[{"msid":45336641,"title":"New hardware to boost efficiency of internet devices","entity_type":"ARTICLE","link":"\/news\/new-hardware-to-boost-efficiency-of-internet-devices\/45336641","category_name":null,"category_name_seo":false}],"related_content":[],"msid":45368395,"entity_type":"ARTICLE","title":"Ericsson working on technology to beat frequency limits","synopsis":"\u201cOperators in India are challenged for spectrum, but as a result of it comes some of the best technology innovations,\u201d Arun Bansal said.","titleseo":"ericsson-working-on-technology-to-beat-frequency-limits","status":"ACTIVE","authors":[{"author_name":"Deepali Gupta","author_link":"\/author\/479212148\/deepali-gupta","author_image":"https:\/\/etimg.etb2bimg.com\/authorthumb\/479212148.cms?width=250&height=250","author_additional":{"thumbsize":false,"msid":479212148,"author_name":"Deepali Gupta","author_seo_name":"deepali-gupta","designation":"Correspondent","agency":false}}],"Alttitle":{"minfo":""},"artag":"ET Bureau","artdate":"2014-12-04 10:30:43","lastupd":"2014-12-04 10:50:31","breadcrumbTags":["Telecom Equipments","new technology","Ericsson","Arun Bansal","Spectral efficiency","Radio Buisness Unit"],"secinfo":{"seolocation":"ericsson-working-on-technology-to-beat-frequency-limits"}}" data-authors="[" deepali gupta"]" data-category-name="" data-category_id="" data-date="2014-12-04" data-index="article_1">

爱立信致力于拍频技术的限制

“在印度运营商是光谱的挑战,但由于涉及一些最好的技术创新,“阿伦邦萨尔说。

孟买:瑞典电信设备制造商爱立信正在第四代技术,允许无缝移动通信服务频率和技术标准,可以帮助运营商克服限制频率短缺。

这种技术将在spectrum-starved印度运营商的机会,尤其是那些持有多个频率。可以依赖的主要受益者之一Jio Infocomm,信实工业的单位,电波在1800 Mhz和2300 Mhz乐队和发射服务。
“在印度运营商是光谱的挑战,但由于涉及一些最好的技术创新,“阿伦邦萨尔公司的无线业务单元负责人告诉ET在接受采访时说。
爱立信的技术允许一个电话在不同的乐队:完成一个调用者可以上传他的声音在网络在另一个频率和接收响应。目前是不可能的——例如,如果调用者的手机使用900 MHz频带上传的声音,它将接受被申请人在相同的频率的声音。爱立信的技术已经走出实验室,该公司目前正在与芯片制造商。
较低的频率达到更远,更高的传播更广泛的领域,因此更适合服务更多的客户在这个领域,提供快速的数据服务。的优势新技术是,运营商可以使用较低的部署覆盖面积较大的乐队,将花费更少,并使用更高的乐队扩充能力。连接到网络的设备仍将在两支乐队。
成功的移动部署只用2300 MHz频段可以900 MHz的两倍,专家说,这主要是因为更高的频带需要更多的基站和天线信号在很大面积,较低的乐队。
依赖Jio电波在2300 MHz的乐队,唯一一个在全国有4 g带无处不在。但它一直拖延4 g发射了四年了,担心缺乏一个生态系统和设备的4 g技术会扫兴。今年早些时候,该公司收购了电波在1800 MHz频带,并盯住发射服务两个独立的4 g标准。如果采用爱立信的技术,公司可以降低成本通过部署两支乐队提供服务。
同样也适用于Bharti Airtel的4 g在2300 MHz乐队推出四大城市已不可否认缓慢起动器。全球大约50%的近300在LTE网络,4 g技术,是建立在1800 MHz频带,邦萨尔说。其余的演变主要是降低乐队,除非中国使用2300 MHz。
印度不太可能跳过技术一代之前,将首先体验3 g的轮廓采用下一代技术,邦萨尔说。“回归从2 g到4 g技术并不顺利。如果你看到生态系统3 g终端(手机)可在50美元,4 g的仍然是一些时间。”
为了解决覆盖问题,邦萨尔认为部署商业模式可能会改变。例如,业主可能开始部署内部解决方案和收取租金,他说。
根据他的说法,有更多的运营商在印度不转化为更高的销售设备供应商。“最终重要的是使用,因为能力仍然是12亿人。所以三个运营商还是七个运营商,能力正在建造这些人。”
