5．无线：风景这边独好

2008年全球无线领域的投资比例超过总投资的65 %，成为电信业最大的亮点。3G逐渐成为
互联网接入的主要手段，移动宽带（MBB）开始成为运营商 的主流业务。全球80%以上的
人口在蜂窝网络的覆盖之下，人们越来越多地通过移动装置上网，上网时 间逐渐超过了固定
终端。

与固定接入相比，移动接入的新概念更加丰富：WIS E（无线互联网业务环境）、USN（传感
器网络）、AUN（泛在网络）、Femto、Hybrid 等盛行一时；HSPA 用户全球每月增长400
万，从2007年的1100万增长到2008年的5 000多万，全球93个国家开展了应用；EV-DO
用户全球有9700万，应用在全球103个国家 的169个网络。预计2012年之前，全球3G用
户将远超过16亿。

全球很 多运营商的数据业务在2008年实现超过50％的增长。一些运营商把每月提升1%的
非话音业务收入 占比（年度贡献为12%）作为关键考核指标。 除SMS外，主要的数据业
务还包括音乐、VPN、视 频、游戏等，终端、业务和新商业模式都对移动数据通信产生正反
馈。随着数据业务流量的增加，将进一 步产 生对移动接入、Backhaul、城域、骨干、核心
网的扩容需求。然而，扩容技术复杂，如小 区分裂、Mesh Backhaul、Hybrid容量技术等，
这意味着即使是移动这个亮点，其发 展前景仍存在着很多困难和隐患。同时，IMS、Femto、
LTE等技术的 商用仍将缓慢成熟，期待着本质上的突破。

LTE Watch: Huawei Rides the Rails
Huawei Technologies Co. Ltd. is making some startling speed claims for its LTE testbed
on the Chinese version of the bullet train, in this week's roundup of what's happening in
the world of pre-4G technology.


Huawei has deployed an LTE network to support wireless connectivity on the fast MagLev
train, which runs between the center of the Shanghai district of Pudong out to Pudong
International Airport on 19 miles of magnetic track that the train to achieve
speeds in excess of 250 miles per hour. The company is claiming that its test can give
passengers maximum uplink speeds of 50 Mbits with a 99.5 percent successful handover
rate as the train speeds between cells.

ZDNet Australia took the 20-minute ride to test the network. It reports average downlink
speeds of 46 Mbits and very few dropouts unless another train went past.


This is by no means the only test where Huawei is claiming to be on the leading edge of
speeds offered over LTE. In its tests with mmO2 plc (NYSELondon: OOM) in the
delightful British town of Swindon, Huawei is claiming maximum downlinks of 150 Mbits
on the test network.

O2 has put up a video about its tests with LTE so far:

Debate over whether Verizon Wireless should really move to tiered pricing for LTE is
already heating up in the blogosphere. The operator actually only offers a maximum of 5
Gigabytes a month on its current mobile broadband laptop plan, so
been a fluid concept in this sector.

Surprising news from Pyramid Research suggests that the Middle East will surpass
Europe in early adoption of LTE. expect LTE adoption in the region to reach 6.1
percent of all mobile subscriptions by 2014, due to strong growth of demand for data
services, reliance on mobile rather than fixed access technologies, and the increasingly
competitive approaches of the telecom regulators,Pyramid Research analyst Kerem
Arsal says. One of the reasons driving strong expected LTE takeup in the region is the
lack of wired broadband infrastructure for users that want fast connections.
