EVDO-WiFi Router

Model: WIFI-E100

The EVDO-WiFi Router lets you create your own WiFi hotspot via 3G (EVDO) network at families, small offices, home offices (SOHO), vehicles, and anywhere.

It is designed to provide a more cost-effective solution solution than deploying a new cablevision modem or ADSL modem. And its easy installation and maintenance can help 3G operators get fast return.

You just need to insert an EVDO UIM card into the socket on the router's rear side, and then each WiFi-enabled device (such as a notebook, desktop PC, PDA, game console, cell phone, MP3 player) can connect to the internet when within the range of the router. The router can support 20 to 30 users.

Features:
- Fast installation: without special professional skill;
- Seldom maintenance requirement;
- Multi-function: 3G modem, WiFi router, LAN switch;
- Portable: easy for office re-arrangement.

Application
Suited for the place where EVDO network is available:
- Coffe shops, lounge bar, hotels, restaurants;
- Sports area and recreation centers, like bowling, billiards...;
- Homes, apartements, enterprises in need of Internet sharing;
- Small offices, SOHO;
- Exhibition and convention sites;
- Beaches, gardens, swimming pools...;
- Mobile vehicles (trains, ships, buses, RVs, etc.)

Sharing a Broadband Internet Connection

Raymond J. Smith, WiFi Home Networking, McGrawHill Companies


If you have an existing network, and you’ve just installed a broadband link to the Internet, you can make that link work for all your existing computers, whether the link is via satellite, cable modem, or Telco digital subscriber line (DSL). You should check with your Internet service provider (ISP) before you do so, however, because their policies vary. Most don’t mind customers sharing access among their own PCs. Most do mind customers sharing with friends or neighbors. Some don’t care, and some flatly forbid it and actively seek out users who share in any way. As mentioned in the previous chapter, you should base your choice of ISP on this policy question as well as on other factors.

The simplest way to share an Internet line is to purchase additional Internet Protocol (IP) addresses from your ISP. No providers complain about this method, because they make a profit on the exchange. Prices may vary from $3 to $10 per month, assuming that your ISP is willing or able to sell extras.You will need one for each PC you plan to connect. Afterward, all the PCs will have to be interconnected through a hub or switch, which will also have a line to your broadband modem.

It is possible to achieve the same end by using a clever device that selectively channels traffic between the broadband link and your client PCs. It is called a router. This function can be carried out by a dedicated PC running special software or by a piece of special-purpose hardware. Many hardware routers are made more cost effective by including built-in firewalls
and high-speed switches, which makes them an increasingly popular solution for broadband sharing. Software and hardware routers are Network Address Translation (NAT) devices. They emulate a single PC when they connect to your ISP. They will even perform an auto-logon if they have to. Afterward, any traffic destined for a PC in your home is directed (routed) to it as though it were the only PC, even though you may have several. Similarly, any traffic from any PC to the Internet gets funneled into one DSL line. This provides an extra measure of security for your PCs because to someone on the outside it appears as though only one IP address is active. In this way, a NAT router acts as a firewall.

Another measure of security is gained from the range of IP addresses distributed to the clients, because they belong to a special class:
- 10.0.0.0 to 10.255.255.255
- 172.16.0.0 to 172.31.255.255
- 192.168.0.0 to 192.168.255.255 (the most common)

Addresses in this range function like any others, with the exception that Internet routers won’t pass them along. This means that your PCs are more isolated and therefore more protected. A hacker trying to access any of your addresses within these limits will have no luck, as his or her packets will hit an immediate dead end. DSL and cable are full-time Internet connections.

They make your PCs easier to find and more vulnerable to attacks from malevolent hackers than they were on your old dial-up connection. This is especially true if you have a static IP address since a hacker can automatically “bookmark” your home network and return to it at leisure.

IEEE Wireless Standards

Raymond J. Smith, WiFi Home Networking, McGrawHill Companies


The first attempt at a wireless standard was the HomeRF protocol, which did not catch on because of its slow (1.6 Mbps) speed. It was replaced by the
802.11 standard, which ran at 1 or 2 Mbps. Because of its limited speed, it is also history. In 1999, the IEEE added the “a” and “b” refinements.

Products conforming to the 802.11a standard operate at speeds of up to 54 Mbps on a very short-wave frequency of 5 billion cycles per second, or
5 gigahertz, abbreviated GHz. Its speed advantage is offset by its shorter range, which is typically 50 to 200 meters. Unlike the more popular b standard,
it uses a modulation scheme with the hefty name of Orthogonal Frequency Division Multiplexing (OFDM) that makes possible data speeds as
high as 54 Mbps and cuts down on cross-channel and reflected-signal interference. More commonly, communication takes place at 6, 12, or 24 Mbps.

Today the most widely followed standard by far is known as IEEE 802.11b. It moves data at a top speed of 11 Mb ps in the 2.4 GHz frequency
band. It is more prone to interference than 802.11a, but the lower frequency gives it a longer range, estimated at between 75 to 300 meters.

The 802.11g standard is now under development and discussion by members of the IEEE, but it won’t become official until released in 2003.
The g standard will be backward compatible with the b standard and will operate on the same 2.4 GHz frequencies. But it will be faster at 54 Mpbs
and less vulnerable to radio noise. Its greater capacity makes it a promising media for wireless streaming video.

As often happens with a burgeoning technology, as soon as the Committee handed down the standard, it began amending it. Other additions are in
the IEEE pipe:
1. 802.11d and h will accommodate European regulations governing radio devices.
2. 802.11e is due in January 2003. It adds quality of service (QoS) features.
3. 802.11f will add protocols that enable data sharing between disparate systems in 2003.
4. 802.11i addresses security holes in the present standards.
5. The Wireless Next Generation (WNG) specification seeks to combine all the above into one universal standard.
6. Ultrawideband (UWB) was granted a limited license in February 2002 for use in the 3.1 GHz and 10.6 GHz bands, but only indoors or in handheld peer-to-peer applications for now.
