Wireless Internet Service Provider (WISPs)

Wireless Internet Service Provider (WISPs) are internet service providers with networks built around wireless networking. The technology used ranges from commonplace Wi-Fi mesh networking or proprietary equipment designed to operate over open 900MHz and 2.4GHz bands or licensed frequencies in the UHF or MMDS bands.

In 2005 the Federal Communications Commission released Report and Order, FCC 05-56 that revised the FCC’s rules to open the 3650 MHz band for terrestrial wireless broadband operations. On November 14, 2007 the Commission released Public Notice (DA 07-4605) in which the Wireless Telecommunications Bureau announced the start date for licensing and registration process for the 3650-3700 MHz band.

BroadBand Internet Access

Broadband Internet access, often shortened to just broadband, is high-speed Internet access—typically contrasted with dial-up access over a modem.

Dial-up modems are generally only capable of a maximum bitrate of 56 kbit/s (kilobits per second) and require the full use of a telephone line—whereas broadband technologies supply at least double this speed and generally without disrupting telephone use.

Although various minimum speeds have been used in definitions of broadband, ranging up from 64 kbit/s up to 1.0 Mbit/s, the OECD report is typical in counting only download speeds equal to or faster than 256 kbit/s as broadband, and the US FCC use 200 kbit/s in their definition.

Speeds are defined in terms of maximum download because several common consumer broadband technologies such as ADSL are “asymmetric”—supporting much slower maximum upload speeds than download.

“Broadband penetration” is now treated as a key economic indicator.

Satellite Internet Access

Satellite Internet services are used in locations where terrestrial Internet access is not available and in locations which move frequently. Internet access via satellite is available worldwide, including vessels at sea and mobile land vehicles. There are three types of satellite Internet service.

Remote sites use the proxy server at the earth station (teleport), which is configured to route all outbound traffic to the QoS server, which makes sure no user exceeds their allotted bandwidth or monthly traffic limits. Traffic is then sent to the encapsulator, which puts the IP packets inside of DVB packets. The DVB packets are then sent to the DVB modem and then to the transmitter (BUC).

Power-Line Internet

The advantages of a power-line network:

It’s inexpensive. It uses existing electrical wiring. Every room of a typical house has several electrical outlets. It’s easy to install. A printer, or any other device that doesn’t need to be directly connected to a computer, doesn’t have to be physically near any of the computers in the network. It doesn’t require that a card be installed in the computer (although there are companies working on PCI-based systems). The new PowerPacket technology provides a couple of other advantages as well. It is fast, rated at 14 megabits per second (Mbps). This speed allows for new applications, such as audio and video streaming, to be available throughout the house. There are some disadvantages to connecting through power-lines when using the older Intelogis technology:

  • The connection is rather slow — 50 Kbps to 350 Kbps.
  • The performance can be impacted by home power usage.
  • It can limit the features of your printer.
  • It only works with Windows-based computers.
  • It uses large wall devices to access an electrical outlet.
  • It can only use 110-V standard lines.
  • It requires that all data be encrypted for a secure network.
  • Older wiring can affect performance.

New power-line networking products are based on Intellon’s PowerPacket technology.

According to Intellon, PowerPacket technology eliminates many of these concerns, citing the following advantages:

  • It is very fast, rated at 14 Mbps.
  • It “avoids” disruptions in the power-line, maintaining the network’s connections and speeds.
  • It does not limit the features of your printer.
  • It can be compatible with other operating systems (depending on driver availability).
  • It may have the necessary circuitry embedded within the device, necessitating only a standard power cord to access an outlet.
  • It works independent of line voltage and frequency of current.
  • It includes encryption.
  • In tests, it showed no signal degradation due to older wiring.

Wireless Broadband

Wireless Broadband is a fairly new technology that provides high-speed wireless internet and data network access over a wide area.

According to the 802.16-2004 standard, broadband means ‘having instantaneous bandwidth greater than around 1 MHz and supporting data rates greater than about 1.5 Mbit/s. This means that Wireless Broadband features speeds roughly equivalent to wired broadband access, such as that of ADSL or a cable modem.

Technology and speeds

Few WISP’s provide download speeds of over 100 Mbit/s; most broadband wireless access services are estimated to have a range of 50 km (30 miles) from a tower. Technologies used include LMDS and MMDS, as well as heavy use of the ISM bands and one particular access technology is being standardized by IEEE 802.16, also known as WiMAX. WiMAX is highly popular in Europe but has not met full acceptance in the United States because cost of deployment does not meet return on investment figures. In 2005 the Federal Communications Commission adopted a Report and Order that revised the FCC’s rules to open the 3650 MHz band for terrestrial wireless broadband operations. On November 14, 2007 the Commission released Public Notice DA 07-4605 in which the Wireless Telecommunications Bureau announced the start date for licensing and registration process for the 3650-3700 MHz band.

Initially, Wireless Internet Service Providers (WISPs) were only found in rural areas not covered by cable or DSL.[4] These early WISPs would employ a high-capacity T-carrier, such as a T1 or DS3 connection, and then broadcast the signal from a high elevation, such as at the top of a water tower. To receive this type of Internet connection, consumers mount a small dish to the roof of their home or office and point it to the transmitter. Line of sight was usually necessary for this type of technology, but technologies by Motorola have not adhered to this general rule.

Mobile wireless broadband

Wireless broadband technologies also include new services from companies such as Verizon, Sprint, and AT&T Mobility, which allow a more mobile version of this broadband access. Consumers can purchase a PC card, laptop card, or USB equipment to connect their PC or laptop to the Internet via cell phone towers. This type of connection would be stable in almost any area that could also receive a strong cell phone connection. These connections can cost more for portable convenience as well as having speed limitations in all but urban environments.

Speedier but Heftier ISP Deals

For people who have been hooked on to the Internet these days, it remains that the only important thing is being connected on the web. Now the speed of your connection will vary. We have been witnesses to various Internet connections such as:

  1. Dial Up
  2. Cable
  3. DSL
  4. Broadband

Of these choices, we will of course choose the faster connections. But if you are just checking your email or surfing for a couple of minutes, do you really have to pay for the service that may not be justifiable if you are not a heavy Internet user?

These are things to consider. We need to save these days and whittling down our expenses such as ISP subscriptions can be a big help towards us.

High-Speed Packet Access

High-Speed Packet Access (HSPA) is a collection of mobile telephony protocols that extend and improve the performance of existing UMTS protocols. Two standards, HSDPA and HSUPA, have been established and a further standard, HSOPA, is being proposed.

The two existing standards (HSDPA and HSUPA) in the family provide increased performance by using improved modulation schemes and by refining the protocols by which handsets and base stations communicate. These improvements lead to a better utilization of the existing radio bandwidth provided by UMTS.

The number of commercial 3.5G networks–also known as High-Speed Downlink Packet Access, or HSDPA, networks–launched worldwide grew by 69 percent in 2007. There are now 174 commercial HSDPA networks in 76 countries. An additional 38 networks are committed to rollouts, which will bump the total to 211 HSDPA networks in 90 countries. Commercial HSDPA networks are widely available in Western Europe (61 networks), Southeast Asia (35), Eastern Europe (34), the Middle East and Africa (20), and the Americas and the Caribbean (16). Almost two-thirds (62 percent) of existing commercial HSDPA networks support downlink speeds of 3.6Mbps or more, while more than a fifth (21 percent) support the peak downlink speed of 7.2Mbps.

Many HSPA rollouts can be achieved by a software upgrade to existing 3G networks, giving 3.5G a headstart over WiMax, which requires dedicated network infrastructure. Rising sales of HSPA-enabled mobiles–aided by more-generous-than-expected operator subsidies of the hardware–are helping to drive the 3.5G market.
