China Wireless Technology Conference
Organizer: Mainly some media such as people's post, China radio.
Behind the consortium: mainly Intel, North Electric, Freescale chip manufacturer.
In four local sites, Shenzhen, Chengdu, Nanjing, Shanghai.
The speakers are mainly: 1. Operators, telecommunications, Netcom, no mobile operators. 2, main system manufacturers: Northern Electric, Motorola, Cisco, Huawei 3, program and chip supplier.
Arrangements and trips in Shenzhen:
1. The first is the leadership speech, and the time is 30 minutes.
2, telecom operators speak: main content
1) Introduce the construction of WLANs. Mainly certified, safe, and access methods. The key point has ACs to use Huawei ISN8850, certified with PPPoE and DHCP web, divided VLAN to distinguish between networking, future hopes WLAN CDMA1x, can adopt networks of city channels.
2) The positioning of the WLAN system is a supplement to the 3G service, which is made as an appreciation service.
3, Netcom operator spoke: Main content:
1) First introduced 3G, the views of the three standards, and then mention that the fixed network operator last year is very difficult,
2) Support some of its own views on 802.16 technology, mainly thinking that technology is immature, integrity, construction and maintenance costs are also too high, mention two policy risks 1-3G license 2-VoIP supervision.
3) This year's focus is IPTV and video calls, transformed the ADSL line, so that there is 2M bandwidth, which can operate IPTV. I hope to build a voice, data, and video unified carrier network.
4) Suggestions on WiMAX: do not use public and non-approval frequencies, the operator selects a certain frequency for equipment merchants.
5) The voice becomes a value-added service, the aggravation portal and content is provided. Let customers ignore the technology used, focus on business and service.
6) These are capital oligarchy, and the return will be long.
4, two foreigners speaking, mainly introducing 802.15 protocols, as well as wireless USB technology, total applications are digital home and sensor networks, these two markets are very large.
5, Huawei spoke: 1- Introduced Huawei's understanding and history of WiMAX, Huawei's 2000 tracking, June 2004, June 2004, prepare to release WiMAX 802.16D products in July this year, mainly in wireless access and base station interconnection .
Eating at noon, it is more expensive, it is difficult to eat, depressed one noon.
6, Nortel Network Speech: Propose WiFi WiMAX Network Program, claiming to claim to be revolutionary, qualitative WiFi network scheme, mesh network, is to turn the AP into a node that can automatically topology, with WiMAX, can independent Network. It has now been started in Taipei and Kaohsi. Key points to deploy such a network, applicable, such as public security, transportation, education, etc. Among them, the network of Kaohsiung is the government's investment, not an operator.
It is in contact with operators, saying that China Mobile is studying this application.
7. Motorola spoke: Motorola independently of the network from the cellular phone, becoming a parallel departments of 2G / 3G, mainly driving similar bridge, wireless access, mesh net things, and 802.16d, 802 .16E This product. The spokesperson is leaking, and it is negotiating with operators and hopes to build such a test network. Someone asked this network and 3G relationship, answer: mutual supplement, focus, 3G is mainly voice, the speed is relatively slow, and the cost is much more expensive than WiMAX, WiMAX network focus is data Voice is a weakness, but the cost is very low. 8, Ovantone speaking, introducing our WiMAX products, blowing a pass.
9, SEQUANS, providing manufacturers of chips and programs, but also blowing, their own products have no shortcomings, let people listen to people are very suspicious and very depressed.
10, then draw, but unfortunately an ipodmp3 flower.
Total feel:
WiFi WiMAX has many large manufacturers and operators to join, adopting new technology and networking programs, and independent networking is very likely to implement. From the data application, if a 1M data is transmitted, such a network is much cheaper than 3G.
802.16D products are in this year, and large manufacturers will be released.
802.16e's products are released in the first quarter of next year.
