For Long Term Evolution (LTE), the next-generation (post 3G) wireless broadband technology, today is a red-letter day. Why? Because one of the world’s largest wireless companies switched on its LTE network, ushering in a new high-speed wireless era, which will not only have technological, but also economic and social impacts. And while it is nice for us to celebrate Verizon’s newest offering, one cannot forget that the LTE revolution is spreading across the world like a house on fire.
So we decided to pour through our archives and talked to our
telecom industry contacts, and have put together a handy snapshot
of LTE across the planet.
So here goes:
Germany: 沃达丰宣布,当地时间12月1日在德国正式启动LTE服务。沃达丰在德国的LTE网络仅支持消费者及企业用户在热点区域使用数据卡应用,数据卡提供商为三星。此前,沃达丰选择华为及爱立信为其建设德国的LTE网络,并计划将在德国的所有基站升级至LTE。按照计划,沃达丰的LTE网络将在2011年3月前,覆盖德国1500个居民点。9月,沃达丰曾在滨海渡假地海利根达姆推出LTE的业务。沃达丰的LTE业务提供的套餐包括:39.99欧元可使用7.2Mbps无线宽带接入,49.99欧元可升级至21.6Mbps,69.99欧元则可升级至50Mbps。
China: It has been a late bloomer, but forecasts say that the world’s largest mobile market will have 57.9 million LTE connections by 2015, many of them using a Chinese variant of the mobile technology. China Mobile had put together an experimental TD-LTE network for World Expo Shanghai, held earlier this year. The company so far has built up 11 small TD-LTE networks and will be launching three trial networks in three costal cities – Xiamen, Zhuhai and Qingdao. Huawei is the key supplier to China Mobile.
Japan: NTT DoCoMo is all set to launch its LTE network later this month, probably around Christmas. The service is called Xi. Other major telecom companies in Japan are going to follow suit. Softbank will launch an LTE network in 2011 and EMobile in 2012. KDDI is currently trialing a LTE network with gear from NEC on 1.5 GHz frequencies, and that network should go live in 2012. KDDI also owns 800 MHz spectrum, which will be used for LTE too. Japan will have 26.5 million LTE connections in 2015.
India: The world’s second largest market is
reeling from a massive scandal around the 2G technologies, which
has left many shocked. [LINK?] The country is woefully late in its
3G deployments and in general is a wireless mess. And despite all
that, Alcatel-Lucent
expects that there will be some commercial LTE deployments by
the third or fourth quarter next year. India sold off 4G licenses
(2.3 GHz spectrum) in June 2010. I don’t believe anything
representatives of local vendors have to say, so I would say take
this claim with a pound of salt.
Rest of Asia: CSL of Hong Kong launched Asia’s first LTE network right before the Thanksgiving weekend. Singapore’s SingTel is currently trialing an LTE network that is likely to be launched sometime in 2011. Korea Telecom is likely to launch an LTE network in July 2011 in the 850 MHz band. Asia (excepting China/India) is expected to have about 65 million LTE subscribers by 2015 with Indonesia representing 13.1million connections, South Korea 9.8 million and Australia with 4.3 million connections.
Scandinavia: TeliaSonera of Sweden became the first network operator to launch a LTE network in December 2009, and since then many other new networks have come on line in Scandinavia, once the epicenter of wireless world. Telia recently launched a LTE network in Finland on December 1, 2010, adding to the list of networks it has operational in Norway and Uzbekistan. Denmark is next. Telia’s rivals, Tele2 and Telnor have rolled out a LTE joint venture, Net4Mobility.
In addition to these bigger markets, here are some developments.
- Trials have begun in Argentina, but spectral constraints are causing LTE delays in Latin America and don’t expect LTE to make a major splash before 2013, though countries like Brazil might see it come sooner. There are trials under way in Chile, Peru, Mexico and Columbia.
- Russian carrier Yota has made the switch from WiMAX to LTE.
- MetroPCS was the first major to launch a LTE network in the US.
- Harbinger-backed LightSquared is currently building a nationwide LTE network in the US.
