Inside wireless and mobile technologies
Although you don't need to be a technology wizard to take advantage of wireless technologies, you can make better decisions about which solutions are best for you if you have a basic understanding of the terms and concepts associated with wireless. Generally speaking, wireless is a technology that uses radio waves rather than wires to send data along a communication path. Wireless devices can operate in three different network environments:

1. Wireless PANs (Personal Area Networks): a small collection of mobile devices that make up a piconet (tiny network), typically located in one room. The PAN replaces the wires that would normally connect one piece of equipment to another. For example, a PAN may connect a desktop to a nearby printer, digital camera, scanner, keyboard, mouse, and PDA. In a PAN, each mobile wireless device communicates directly with other devices, and devices must be relatively close together -- typically within 33 feet of each other.
2. Wireless LANs (Local Area Networks): a workgroup of wireless devices joined into a network, yet spread out over an entire office or perhaps one floor of a building. Instead of using cables to connect desktops and servers to the network, wireless LANs connect mobile devices to a small collection of wireless access points that are wired to the network. For example, employees with wireless notebooks or PDAs can access the Internet using wireless access points affixed to the ceiling in your office, and they are able to move from room to room without losing their connectivity. In a wireless LAN, each mobile wireless device communicates with the access point, which can be several hundred feet away.
3. Wireless WANs (Wide Area Networks): a network of wireless devices that work beyond a single building, operated by a public carrier such as your cellular provider. In a wireless WAN, you can use wireless to reach a carrier's voice or data network instead of plugging your notebook into a phone jack and dialing into the Internet. For example, field personnel can check prices or inventory while visiting a customer site by using a wireless WAN to query a database back at the office. In a WAN, each mobile device communicates to a public carrier's base station. Public carriers install networks of base stations (similar to cell phone towers) throughout large geographic areas, effectively providing coverage across entire states, regions, or even countries.
   

Utilizing these technologies has become much easier in recent years. Furthermore, industry standards have significantly stabilized and vendors of hardware and applications/software have created offerings with robust capabilities -- this means that data is kept safer during a wireless transmission or when a device is lost or stolen.

Wireless protocols
For computers, handhelds, printers, and other wireless devices to communicate with a wireless network, they have to speak the same language (technically called a protocol). Each type of wireless network has its own protocols and standards:  

• Bluetooth and Infrared for PANs

• BluetoothT (also known as the IEEE 802.15 standard for wireless PAN communication) is ideally suited for connecting up to eight devices within a single room. BluetoothT operates in the 2.4 GHz radio band (part of the "Unlicensed Spectrum" that does not require the user to obtain a license to operate the equipment). To minimize potential interference from other devices that might transmit in the same band, BluetoothT uses a technique called FHSS (Frequency Hopping Spread Spectrum) to ensure that each device transmits only briefly on a given radio channel and then moves (hops) to another channel.

• IR (Infrared) communication is a BluetoothT alternative that allows you to connect two devices that have built-in IR ports and are located in the same room. Simply line up the devices' IR ports and beam (or send) data.

• Wi-Fi for LANs: The IEEE 802.11 family of standards was introduced to establish a common, secure set of standards for device-to-device data communication over wireless in much the same way that Ethernet (IEEE 802.3) connects computers on a wired LAN. On a wired network, computers are connected to the network by cables plugged into Ethernet hubs and switches. In a wireless LAN, computers connect to the network by sending radio signals to an access point. Each access point is connected to a wired network and it relays traffic between wireless devices and the wired network. Today, most wireless LAN products support 802.11b (also called Wi-Fi), a standard that operates in the 2.4 GHz band at speeds up to 11 Mbps. However, a growing number of products are beginning to support two newer standards: 802.11a (operating in the 5 GHz band at speeds up to 54 Mbps) and 802.11g (sharing the same 2.4 GHz band at speeds up to 54 Mbps). As with BluetoothT, these frequencies were chosen to allow unlicensed operation.

• CDMA2000 and GPRS/EDGE for WANs

• CDMA2000 is a second-generation (2G) protocol originally designed to carry voice and then retrofitted to carry a modest amount of low-speed data traffic. 2G data services can support brief e-mails and other short transactions, but are too slow for transferring large files.

• GPRS (General Packet Radio Service) is an advanced wireless data network. Although it is faster than a 2G network, it is slower than a true third-generation network (3G network -- see below). For that reason, it is often referred to as a 2.5G network. GPRS uses exactly the same network as GSM, the voice network. A typical 2.5G network can transfer data at 40 to70 Kbps, a bit faster than v.90 dial-up Internet access, and is suitable for conducting business activities such as checking e-mail.

• EDGE is an upgrade to the GPRS network that offers 3G data services (>100 Kbps). These networks offer the promise of megabit speeds in the future to carry multimedia content.

DISPELLING WIRELESS MYTHS
Wireless is one of the hottest technology topics and as such receives a great deal of press. As is true about many other technologies before it, wireless has its fair share of myths about problems and risks. If any of these myths are preventing you from taking full advantage of the business benefits of wireless, read on to discover the truth behind the myths and remove them as a roadblock to your wireless success.

Myth: "Wireless LANs are not secure."

The most commonly cited myth about wireless networks is that they aren't secure. In reality, technologies and software exist to make a wireless network as secure as any wired network.

HP offers the latest in wireless security so you can implement a wireless network out of the box with confidence and without hiring an IT specialist. HP products support integrated data encryption as well as user and device authentication systems so that you can be sure that your data is secure. If you need additional assistance with specific security needs, contact an HP mobile and wireless expert.

Myth: "If I lose my notebook or handheld while on the road, I'll expose my company's confidential information."

HP ProtectTools makes it easy for you to protect and encrypt the data on your notebook or handheld so if it is lost or stolen, the data isn't compromised. HP is also working with best-in-class partners like Credant to provide solutions that extend security beyond the device and make managing security for all of your company's mobile devices easier.

Myth: "Wireless is only for road warriors."

Even though they don't travel away from the office during the day, your onsite staff members may find that they are spending a good portion of their workday away from their desk with limited access to their computer, printers, and the network. When you combine wireless connectivity with notebooks, tablets, handhelds, projectors, and even printers, all of your employees can continue to be productive even when they are away from their workspace.

Myth: "Wireless networks are expensive."

When you remove the cost of running wires throughout a building from the equation, you take away one of the most expensive elements of setting up and maintaining a network. HP wireless solutions can cost up to 30% less than creating equivalent wired networks, and the total cost of creating a wireless network that works with your existing technology can be as little as a few hundred dollars.

Myth: "Wireless networks are hard to set up."

HP delivers end-to-end wireless solutions including wireless notebooks, Tablet PCs, iPAQ handhelds, printers, projectors, and access points that are easy to set up and use. However, finding the right wireless networking solution with the right capabilities for your size business can be a challenge, as can finding the adequate in-house expertise and time to install and implement the wireless solution you choose. To make the entire process easier and more cost-effective, HP offers two affordable Care Pack services to help you sift through the options and implement cost-justified wireless solutions much faster, with less risk and less disruption: the HP Wireless LAN Site Assessment Service and the HP Wireless LAN Installation and Startup Service.

Myth: "I have to replace my wired network with wireless equipment to use wireless technology."

If you already have a wired network, you can easily extend it by adding wireless capabilities. Simply connect an HP wireless access point to your network and add wireless cards to your mobile devices. Expansion is easy -- just add another card or a wireless access point. Installation is simple and the technology is inexpensive

Myth: "Accessing e-mail with attachments, calendar, and contacts real time is expensive."

HP works diligently to be sure that cost doesn't prevent a business of any size from taking advantage of the latest in wireless and mobile technologies to stay connected with key business information. Our preferred partners offer specific capabilities that enable secure e-mail access for your business.

You only have to pick up a paper or hear the daily business news to know that viruses and hackers are a real threat to business networks of all sizes. The question is no longer "Is there a threat to my business?" but instead, "What should I do about it?"

HP backs this solution with a year of free phone support from some of the most experienced security engineers in the business. For safer network security, this solution classifies attacks and rapidly detects, prevents, and responds to potential network intrusions by examining each data packet that tries to enter a network.

Slow down new and unknown worms Antivirus software is designed to look for virus signatures and trap infiltrators before they can spread through your network. However, when a new worm virus is first released and its signature is unknown, that virus can potentially run rampant on your company's network. The virus attacks at machine speed and there's simply no way for humans to keep up.

HP Labs has developed Virus Throttle technology designed specifically to slow the spread of new, unknown worms so their damage to your network is as minimal as possible. Virus Throttle technology targets virus behavior instead of the virus signature.

Viruses tend to try to connect to many machines quickly, as opposed to uninfected machines that typically make fewer connections more slowly to fewer machines. When the technology detects rapid connections to many machines, it automatically limits the number of connections the potentially infected system can make and notifies an administrator of the potential problem. The Virus Throttle technology hampers, contains, and mitigates attacks to buy you time to respond.

HP's new Virus Throttle technology is currently available in select HP networking and server products:

• The ProCurve Networking Switch 5300xl comes with Virus Throttle technology built in and, when used as a router, can completely stop routed network traffic from infected network systems from propagating to the rest of the network. Because the ProCurve Switch 5300xl can monitor all ports on the switch for worm virus activity, virus throttling on the ProCurve Switch 5300xl provides a centralized ability to control worms. A free software update for the switch strengthens the security of your network, and gives network administrators more options to manage access for different classes of users. In addition, it prevents Denial of Service (DOS) attacks from impacting network availability, which increases network uptime and resiliency. It also simplifies and automates configuration of network devices to reduce the costs of deployment.
• The ProLiant Intelligent Networking Pack with Virus Throttle technology protects the local network environment in case one of your individual ProLiant servers becomes infected with a worm virus. This can help slow the spread of a virus from an infected server to other servers on your network.
