Wireless Wi-Fi or ev-do, in the end how to choose?

If your company is in the Tempe City of Arizona, State, you now face the choice of spending money on large area Wi-Fi or cellular digital services like 1X ev-do.

Wireless network problems As with most other things, finding the answer is not easy. Maybe you need to pay for both of these, depending on your end-user needs and the applications they use.

Currently, Wi-Fi providers are already using low monthly rents and high bandwidth to woo customers, and their services have been able to compete with cellular phone service providers like Internet services, VPN connections to corporate networks, and VOIP voice phones. Their services have a market for both business and personal mobile users.

To provide this service, the IEEE 802.11 standard mesh Network has been established in a large area, just like the Waztempe wireless network, which was established last week by the MobilePro Wireless branch Neoreach wireless network operator. Like almost all internet companies, Waztemp also operates in unlicensed 2.4GHZ and 5GHz wireless bands.

The entire network contains 550 outdoor nodes and wireless access points provided by the Strix systems. Each access point can connect two 802.11b/g standard client devices, while the two-way 802.11a standard wireless communication can be routed to adjacent access points. In 12 locations, these devices are connected to the latest Gigabit Ethernet fibre of the Cox Communications Company (Cox Communication Inc.). (Computer science)

Ryan Mccaigue, Neoreach's engineering director, said: Neoreach uses encrypted 802.1X protocols to identify users, then allocate users to unused VLANs, and can implement different quality of service, depending on what service options the user chooses.

In this way, neoreach companies and retailers that service through the wireless network infrastructure already have 1500 users. Their main goal is business users, because business users need higher bandwidth, stricter quality service guarantees, and special equipment like high gain or directional antenna.

The initial scheme is the monthly 29$, the bandwidth is 384kbit/sec upload speed and 1mbit/sec speed. In contrast, Mccaigue said, his own mobile phone calls only a month to spend 60$, of course, for about 210kbit/sec to 400KBIT/SEC data Services also need to spend more 40$.
It sounds like an easy thing for a network supervisor, doesn't it?

No brains, no way.

Let's look at some other remarks first.

In this report, co-author Phil Redman came to the conclusion that Boston's Yankee Study Group Inc. was submitting a report called "The Myth and reality of Wi-Fi mesh networks." "There is a limit to what you can do with unlicensed wireless communications," he said. "It is a fact that even though Wi-Fi is developing quickly, including 802.11n, it is assumed that by 2007 bandwidth reaches 300mbit/sec to 400mbit/sec, the service provider can also play to the top."

But retailers like Neoreach, as well as Strix System Inc.,tropos Networks Inc,belair Networks Inc., are deploying large-area Wi-Fi networks across the United States, which they all think is possible.

"If we're talking about technology, then these types of networks have covered some areas and have been used," says Redman. ”

However, whether Wi-Fi networks can become a pillar of the economy is still unclear. "For Wi-Fi business models, it is very difficult to work independently from a service that already has a certain market size," he said. ”

What a mobile worker needs

Bob Egan, new technology director at Tower Group Inc., is skeptical about whether Wi-Fi mesh networks can be deployed to mobile companies.
"802.11 has never and will not become a large area architecture," said Egan, a founder of the 802.11 standard. The large area Wi-Fi network is just a risky investment desire, not a practical structure. ”

He makes the assumption that you're sitting in a café using your laptop wireless office and you're about to make a deal with one of your clients, while three teenagers are playing a game that takes up a lot of bandwidth. Egan said: "You are trying to make money, but they are not." How do you say that in a commercial position? ”

Meanwhile, the ev-do service of Sprint Nextel crop, offers two solutions to business users. The first scheme, flexible connection, that is, the basis for each month 40$ cost to obtain a 40MB flow scheme. If the user needs to pay 0.001$ per thousand bytes over 40MB, the capping fee is 100$. The second option is unrestricted connection, the monthly fee is 80$, there is no limit to wireless data transmission.

Sometimes, the potential cost of Wi-Fi service is to have to pay the service provider in a separate location on weekdays. Of course, when the business and Wi-Fi service signed a contract, there will be no problem.

This ev-do is also feasible, it can achieve 400kbit/sec to 700KBIT/SEC data transmission rate, the maximum can reach 2mbit/sec. With the same wireless access card, users can still access the Internet using the Sprint PCS slow network, which is equivalent to using a dial-up modem or DLS.

Unity, consistency, simplicity

Connection speed, uniform, consistent, simple, and secure access, so that you are in the service area regardless of where, it seems to promote the enterprise to use cellular digital services. Sierra Wireless Inc. has created cards for some telecoms companies, including Sprint and Verizon Communications Inc. For the recent ev-do and high-speed downlink packet Access wireless card, Sierra company marketing and mobile product Department director Greg Speakman said: "We have a very dramatic development process." Sierra has not yet released any products, but it has embedded its ev-do modem in Lenovo and HP's laptops.

For Neoreach Company's Mccaigue, Tempe City will not have network problems. He said that conflicts can be avoided, and that both client-side wireless reception devices provide sufficient connectivity at their respective access points and the ability to access connections for intensive users.
