With the AT&T and Barnes & Noble deals in place, Plastic Logic will be able to match functions of the Kindle, which uses Amazon's e-book store and a wireless connection provided by Sprint Nextel Corp.
Plastic Logic hasn't said what its device will cost, or how users will pay for the use of AT&T's network. Kindle users don't pay Sprint directly. Instead, Amazon pays the carrier using proceeds from its book sales. Nielsen Co. analyst Roger Entner has estimated that the carrier gets about $2 per month per Kindle user.
AT&T is eager to see more non-phone devices use its network, and has set up an Emerging Devices division to attract manufacturers. Other carriers are doing the same. An executive at competitor Verizon Wireless said in April that the carrier had been approached by five companies about wireless connections for e-readers.
Most hotels in Japan offer free internet in their guest rooms through a wireless network and/or wired internet via LAN cable. Internet in the room is slightly less common at ryokan. Instead, some ryokan provide wireless internet or a public computer in their lobby.
Both paid and free wireless (Wi-Fi) hotspots are available across Japan, which laptops, smartphones and other mobile devices can use to connect to the internet, especially around airports, train stations, convenience stores, restaurants, coffee shops and bars.
Thanks to efforts by businesses and governments, public Wi-Fi networks for free use by foreign tourists have become quite numerous. Tourists will encounter these networks at international airports, major railway stations (including all Yamanote Line stations and many shinkansen stations), inside an increasing number of trains and buses, selected coffee, fast food and convenience stores and many tourist information offices.
Wi-Fi routers (also called personal hotspots, personal Wi-Fi, pocket Wi-Fi, etc.) are small, battery-powered devices that use the cellular phone network to create a local wireless network. They are easy to set up, provide reasonably fast internet, work anywhere there is cell phone service, allow multiple devices to connect at once and are relatively inexpensive. Wi-Fi routers are available to rent on a daily basis at major Japanese airports or via the internet for delivery to your home or hotel.
The eduroam network provides wireless access to UNLV students, faculty, and staff who have a valid ACE account. It allows for a secure, seamless connection to wireless services at thousands of participating eduroam institutions. eduroam is also available to campus guests who use the service at their home institution. If you have university devices that are not capable of using eduroam, please contact the IT Help Desk for assistance.
Most wireless networks are based on the IEEE 802.11 standards.A basic wireless network consists of multiple stations communicating with radios that broadcast in either the 2.4GHz or 5GHz band, though this varies according to the locale and is also changing to enable communication in the 2.3GHz and 4.9GHz ranges.
802.11 networks are organized in two ways.In infrastructure mode, one station acts as a master with all the other stations associating to it, the network is known as a BSS, and the master station is termed an access point (AP).In a BSS, all communication passes through the AP; even when one station wants to communicate with another wireless station, messages must go through the AP.In the second form of network, there is no master and stations communicate directly.This form of network is termed an IBSS and is commonly known as an ad-hoc network.
Separate from the underlying transmission techniques, 802.11 networks have a variety of security mechanisms.The original 802.11 specifications defined a simple security protocol called WEP.This protocol uses a fixed pre-shared key and the RC4 cryptographic cipher to encode data transmitted on a network.Stations must all agree on the fixed key in order to communicate.This scheme was shown to be easily broken and is now rarely used except to discourage transient users from joining networks.Current security practice is given by the IEEE 802.11i specification that defines new cryptographic ciphers and an additional protocol to authenticate stations to an access point and exchange keys for data communication.Cryptographic keys are periodically refreshed and there are mechanisms for detecting and countering intrusion attempts.Another security protocol specification commonly used in wireless networks is termed WPA, which was a precursor to 802.11i.WPA specifies a subset of the requirements found in 802.11i and is designed for implementation on legacy hardware.Specifically, WPA requires only the TKIP cipher that is derived from the original WEP cipher.802.11i permits use of TKIP but also requires support for a stronger cipher, AES-CCM, for encrypting data.The AES cipher was not required in WPA because it was deemed too computationally costly to be implemented on legacy hardware.
The other standard to be aware of is 802.11e. It defines protocols for deploying multimedia applications, such as streaming video and voice over IP (VoIP), in an 802.11 network.Like 802.11i, 802.11e also has a precursor specification termed WME (later renamed WMM) that has been defined by an industry group as a subset of 802.11e that can be deployed now to enable multimedia applications while waiting for the final ratification of 802.11e.The most important thing to know about 802.11e and WME/WMM is that it enables prioritized traffic over a wireless network through Quality of Service (QoS) protocols and enhanced media access protocols.Proper implementation of these protocols enables high speed bursting of data and prioritized traffic flow.
FreeBSD supports networks that operate using 802.11a, 802.11b, and 802.11g.The WPA and 802.11i security protocols are likewise supported (in conjunction with any of 11a, 11b, and 11g) and QoS and traffic prioritization required by the WME/WMM protocols are supported for a limited set of wireless devices.
To use wireless networking, a wireless networking card is needed and the kernel needs to be configured with the appropriate wireless networking support.The kernel is separated into multiple modules so that only the required support needs to be configured.
Infrastructure (BSS) mode is the mode that is typically used.In this mode, a number of wireless access points are connected to a wired network.Each wireless network has its own name, called the SSID.Wireless clients connect to the wireless access points.
To scan for available networks, use ifconfig(8).This request may take a few moments to complete as it requires the system to switch to each available wireless frequency and probe for available access points.Only the superuser can initiate a scan:
This section provides a simple example of how to make the wireless network adapter work in FreeBSD without encryption.Once familiar with these concepts, it is strongly recommend to use WPA to set up the wireless network.
Once an access point is selected, the station needs to authenticate before it can pass data.Authentication can happen in several ways.The most common scheme, open authentication, allows any station to join the network and communicate.This is the authentication to use for test purposes the first time a wireless network is setup.Other schemes require cryptographic handshakes to be completed before data traffic can flow, either using pre-shared keys or secrets, or more complex schemes that involve backend services such as RADIUS.Open authentication is the default setting.The next most common setup is WPA-PSK, also known as WPA Personal, which is described in WPA-PSK. 153554b96e
