The Boost4U DW1000 is the 1000 m² commercial model of the DW dual-band series, pairing Band 3 at 1800 MHz with Band 1 at 2100 MHz for an office floor, co-working space, retail shop, hotel, pub, restaurant, clinic, rural warehouse, multi-floor building or community hall. Band 3 carries the EE family's voice calls and 4G LTE data for EE, BT, ASDA and Virgin handsets; Band 1 carries 3G UMTS data and voice across all four networks — EE, O2, Vodafone and Three. Inside the chassis the two stages share ≥70 dB uplink and ≥75 dB downlink commercial gain, a ≥20 dBm output and a ≤5 dB noise figure, fed by the included high-gain Yagi donor aerial and distributed to four indoor whips through the optional 4-way splitter. This deep dive explains what each frequency block carries in the UK, how the commercial gain and output power cover a 1000 m² footprint, which business MVNO rides which host network, what remains covered outside the local 3G footprint, the honest gaps around rural 800 MHz 4G, legacy 2G and 5G, the Ofcom and UK conformity marks behind the commercial install, and how the DW1000 compares with the DW500, DW250 and the other 1000 m² band combos.
Answer first: on Band 3 (1710–1785 MHz uplink, 1805–1880 MHz downlink) the DW1000 amplifies EE-hosted voice calls and 1800 MHz 4G LTE for EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator handsets; on Band 1 (1930–1990 MHz uplink, 2110–2180 MHz downlink) it amplifies 3G UMTS data and voice for EE, O2, Vodafone and Three and their hosted MVNOs. The ≥70/75 dB commercial gain lifts the one to two bar donor picked up by the included Yagi, and the ≥20 dBm output spreads that recovered field through four whips across a 1000 m² premises for up to 100 users. Where the building sits beyond a local 3G footprint, EE-family handsets keep circuit voice on Band 3 while non-EE SIMs rely on the host's own fallback. The chassis does not tune Band 20 800 MHz rural 4G, Band 8 900 MHz legacy voice or any 5G NR layer, and it cannot help where the outside phone reads zero bars.
Band 3 at 1800 MHz: the EE-Family Voice Call and 4G Layer Across a 1000m² Premises
Band 3 occupies 1710–1785 MHz on the uplink, where handsets transmit, and 1805–1880 MHz on the downlink, where the mast transmits. In the UK this block carries the EE family's voice calls, texts and 4G LTE data, and it is the layer that keeps an EE, BT, ASDA, Virgin, Orange, T-Mobile or The People's Operator handset calling and browsing inside an office floor, shop, hotel, pub, restaurant or clinic where the handset alone drops behind masonry, glazing, concrete slabs or a party wall.
Why Band 3 carries both voice and 4G for the EE family
EE allocates its 1800 MHz spectrum across both voice circuit work and 4G packet data; a DW1000 handset on an EE-family SIM therefore keeps a normal circuit voice call and a 4G data session on the same band stages, rather than hopping to a separate voice layer the repeater does not carry. For an EE business account or cafe whose main account relies on reliable calls, texts and outgoing email, this Band 3 layer is the primary service: incoming and outgoing calls, texts, messaging apps and light browsing hold indoors through the reception, meeting rooms, upper office, retail bay and bar area after the 75 dB downlink gain stages amplify the block and the 3 dBi interior whips re-radiate it through the main zone and any split second, third or fourth room.
| Brand | Host | Band 3 service on site |
|---|---|---|
| EE | EE | Voice calls, texts and 1800 MHz 4G LTE data |
| BT Mobile | EE | Voice calls, texts and 1800 MHz 4G data |
| ASDA Mobile | EE | Voice calls, texts and 1800 MHz 4G data |
| Virgin Mobile | EE | Voice calls, texts and 1800 MHz 4G data |
| Orange, T-Mobile, The People's Operator | EE legacy family | Band 3 voice call layer on legacy plans where retained |
The DW1000 amplifies whatever band signals the host mast sends; one serving carrier is tuned band at a time, so a business with an EE main account and an O2 or Three secondary SIM should confirm both hosts' masts are visible through the chosen Yagi position. In a shared, mixed-carrier office, hotel or small business, the EE-family members hold calls on Band 3 while everyone falls back to Band 1 3G as the common cross-network layer.
Band 1 at 2100 MHz: the 3G UMTS All-Networks Fallback
Band 1 pairs 1930–1990 MHz uplink with 2110–2180 MHz downlink. This is the 3G UMTS layer, and on the DW1000 it carries data and voice across all four MNOs: EE, O2, Vodafone and Three. Its job on site is the shared safety net: a handset on a non-EE host cannot hold its own data layer on this chassis, or the building sits outside that newer 4G footprint, the phone steps to the 3G stage the chassis still amplifies.
How 3G keeps every network's calls and data alive indoors
3G UMTS supports circuit voice and packet data; an O2, Vodafone or Three handset that cannot hold a newer 4G bearer can still call, text, send a location fix or hold a low-bandwidth data session over the amplified 2100 MHz block. For a mixed-carrier office, staff on an O2 or Vodafone SIM, a hotel serving guests on several networks, a clinic booking system tethered to an O2 or Vodafone mobile hotspot, and a small business laptop tied to a Three connection all depend on Band 1 redundancy that a single-band Band 3 repeater cannot provide. The chassis tunes both bands together: the main whip feeds both donors, and the three branch whips re-radiate the combined field over floors and zones.
2100 MHz propagation inside brick, plasterboard and party walls
The 2100 MHz band travels shorter distances and loses more through thick brick, concrete, party-wall masonry, bar chrome, kitchen stainless steel and clinic stations than a lower rural band would, which is why the interior whips sit central to the main usage area rather than at the far edge of the premises. The ≥75 dB downlink gain recovers the faint handset-side signal back toward the mast, and the ≥20 dBm output keeps the room field audible across the main zones; an upper office or rear retail bay that reads light on Band 1 is the reason to move that zone's whip toward it or add the fourth branch whip, not to shift the donor mast bearing.
How ≥70/75 dB Gain and ≥20 dBm Output Cover 1000m² with Four Whips
The DW1000's radio numbers are sized for an office floor, hotel, pub, restaurant, retail shop, warehouse or community hall rather than a single flat; gain, output power, noise figure, included Yagi donor aerial and four-whip distribution each play a separate role in that 1000 m² field.
≥70/75 dB: commercial gain matched to the large-premises footprint
Gain is the chassis's amplification of the faint donor signal: ≥70 dB on the uplink from handset to mast, ≥75 dB on the downlink from mast to handset. That commercial-stage recovery sits ten dB above the DW500's ≥60/65 dB figures, and it is what allows the signal to reach a second reception, upper office, rear retail bay, hotel corridor and warehouse zone across 1000 m² rather than stopping at the main room. The 70/75 dB figures recover the one-to-two-bar donor behind glazing and masonry to a usable reading without pushing the stage into feedback inside a confined reception or bar area.
≥20 dBm: commercial output that feeds four branches across the building
The ≥20 dBm figure is the field the interior whips radiate into the rooms; this matches the flagship ≥20 dBm output on the 500 m² DW500 rather than rising further, because the commercial gain and four-antenna distribution carry the footprint expansion instead. The ≤5 dB noise figure keeps the amplified field clear of hiss and noise, and automatic gain control balances the level as handsets approach and leave each whip. The included Yagi matters at this tier because the donor for a large office, hotel or semi-rural warehouse often sits on a distant mast; its directional gain concentrates the receiver on that bearing and feeds a stronger combined Band 3 and Band 1 block into the chassis than a broad omni could pull at the same distance. The four-whip layout then spreads that recovered field over the wide footprint, with the main whip central and the second, third and fourth whips serving the spaces beyond concrete partitions, stairwells or rack rows.
| Parameter | DW1000 figure | What it delivers on site |
|---|---|---|
| Uplink gain | ≥70 dB | Weak handset call and data recovered back to the mast |
| Downlink gain | ≥75 dB | Faint donor amplified to the indoor whips across four zones or floors |
| Output power | ≥20 dBm | Balanced field for up to 100 handsets across four splitter branches |
| Noise figure | ≤5 dB | Keeps the amplified field clear of hiss and noise |
| Users / space | 100 handsets, 1000 m² | Office floor, hotel, pub, restaurant, retail, clinic, community hall, warehouse |
| Outdoor aerial | High-gain Yagi included in the kit | Roof or mast donor pick-up aimed at the best combined mast bearing |
| Indirect hardware | 3 dBi whip, 4-way splitter option | Main whip in the central zone; split whips in separate rooms, floors or bays |
MVNO Host Map: Which Business SIM Rides Which Host on the DW1000
A workplace or hotel using budget SIMs should know which host each brand rides; the DW1000 amplifies the host's Band 3 and Band 1 layers, so a SIM's indoor service follows its leased network rather than its own brand name.
| Brand | Host | Band 3 / Band 1 position indoors |
|---|---|---|
| EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile, The People's Operator | EE | Band 3 voice calls and 1800 MHz 4G plus Band 1 3G fallback |
| giffgaff | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Tesco Mobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Sky Mobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Lycamobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Plusnet Mobile | O2 | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Smarty | Three | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| iD Mobile | Three | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Lebara | Vodafone | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| Talkmobile | Vodafone | Band 1 3G data and voice; no EE-hosted Band 3 call circuit |
| FreedomPop, TalkTalk | Leased fallback host per plan | Check the SIM's current host in the handset status menu; service follows whichever host the plan leases |
Only the EE-hosted brands receive the Band 3 1800 MHz voice and 4G circuit through this chassis; O2-hosted, Three-hosted and Vodafone-hosted MVNOs rely on Band 1 3G indoors. A mixed-carrier office or hotel should test each staff and guest SIM at the main whip before buying the splitter expansion, because a weak non-EE donor bearing limits the Band 1 fallback even where Band 3 holds well.
Voice Fallback Outside the 3G Footprint and the VoLTE Position
Which calls remain connected beyond a local 3G area
If the premises sits outside the local 3G footprint, the EE-family handsets keep circuit voice on Band 3, because that layer is tuned into the DW1000 alongside the 4G data block; an EE, BT, ASDA or Virgin handset can still call and text indoors even where the surrounding area has no 3G coverage on other hosts. A non-EE member of staff or guest on O2, Vodafone or Three loses its repeatable circuit fallback through this chassis, because Band 1 is the only voice layer those hosts receive here; that handset relies on the host's own network fallback, which the repeater cannot create.
VoLTE: where 4G Calling applies
Where the handset and host support Voice over LTE, voice rides the 4G packet layer rather than a separate circuit channel; the DW1000 amplifies the Band 3 1800 MHz layer either way, so an EE-family VoLTE call follows the same amplified block as a normal Band 3 call. If 4G Calling is switched off in the phone settings, the handset falls back to the circuit voice channel on Band 3 for the EE family. This chassis carries no legacy 2G voice band, so a handset that depends on a 2G circuit call cannot be served by the DW1000 even where the host still transmits that layer locally.
DW1000 vs the Lower DW Tiers and the Other 1000m² Band Combos
The Boost4U commercial range splits by tuned band and coverage tier; the DW1000 is the only 1000 m² model that pairs EE-family Band 3 voice and 4G with all-network Band 1 3G. Choosing the wrong combo leaves either the EE call layer or the shared 3G fallback unboosted.
| Model | Bands | Service boosted indoors | Position versus DW1000 |
|---|---|---|---|
| DW1000 | Band 3 + Band 1 | EE-family voice and 1800 MHz 4G plus all-network 3G, ≥70/75 dB, ≥20 dBm, 1000 m², 100 users, four whips, Yagi included | Commercial voice-plus-3G combo for large premises and estates |
| DW500 | Band 3 + Band 1 | Same EE voice and 4G plus all-network 3G, ≥60/65 dB, ≥20 dBm, 500 m², 50 users, three whips, Yagi included | Half the space and users, ten dB lower gain, three-antenna split for a large home or medium business |
| DW250 | Band 3 + Band 1 | Same EE voice and 4G plus all-network 3G, ≥60/65 dB, ≥17 dBm, 250 m², 25 users, three whips, omni with Yagi upgrade | Home-sized footprint, lower output and donor aerial as an upgrade purchase |
| CD1000 | Band 20 + Band 3 | EE, O2 and Vodafone 4G data on 800 and 1800 MHz; no 3G band, no EE voice circuit | 4G data premises without voice calls or 3G fallback |
| CG1000 | Band 20 + Band 8 | O2/Vodafone 4G on 800 MHz plus legacy 2G voice on 900 MHz; no 3G, no EE 4G band | Rural 4G and legacy voice without the EE 4G or all-network 3G layer |
| CW1000 | Band 20 + Band 1 | O2/Vodafone 4G on 800 MHz plus 3G all-networks on 2100 MHz; no EE voice band | Rural 4G data plus 3G without the EE-family voice layer |
Choose the DW1000 where the priority is EE, BT, ASDA or Virgin voice calls and 1800 MHz 4G together with O2, Vodafone and Three 3G across a large premises. Choose the CD1000 for an EE, O2 or Vodafone 4G data workplace with no call band requirement; the CG1000 for O2/Vodafone rural 4G plus legacy 2G voice; the CW1000 for O2/Vodafone rural 4G plus all-network 3G without EE voice; the DW500 for a 500 m² premises, and the DW250 for a 250 m² home or small business space.
Honest Limits: What the DW1000 Does Not Tune, and the Compliance Marks Behind the Install
The bands and services this chassis cannot cover
The DW1000 carries no Band 20 on 800 MHz, so it cannot amplify the rural 4G layer that EE, O2 and Vodafone broadcast at long range; a site whose only outside reading sits on that 800 MHz block should compare the CD1000, CG1000 or CW1000 combos instead. It carries no Band 8 on 900 MHz legacy voice, so a handset relying on a 2G circuit call is not served here, and it carries no 5G NR layer of any band; 5G handsets indoors fall back to whatever 4G or 3G the host transmits on the tuned blocks. The repeater needs at least one to two bars outside the building on the target band; it cannot manufacture a signal where the mast transmits nothing, and it cannot rescue a basement, steel warehouse bay or concrete strongroom that the tuned waves cannot reach from the main chassis.
Compliance, climate and guarantee
The DW1000 is an Ofcom licence-exempt mobile repeater class device for indoor use, aligned with the Ofcom Technical Standard for Mobile Repeaters, carrying UKCA, CE and RoHS conformity marks; the Yagi donor aerial and indoor whips must be spaced to keep the stage from feeding back onto the macro masts, which is the separation rule covered in the installation guide. The chassis operates from minus ten to plus fifty five degrees Celsius, carries a 365-day money-back guarantee and lifetime technical support, and runs on a 5V DC adapter from an AC 100–240 V 50/60 Hz UK mains supply. On a handover between adjacent masts, the chassis follows the donor bearing the Yagi sees; if the premises sits on a soft mast boundary, re-aiming the Yagi toward the stronger combined bearing is the first check before assuming the chassis gain is at fault.
Frequently Asked Questions
Which paired bands form the DW1000 radio system, and what voice and data service does each carry across a 1000m² commercial site?
Band 3 at 1710–1785 MHz uplink and 1805–1880 MHz downlink carries EE-family voice calls, texts and 1800 MHz 4G LTE for EE, BT, ASDA, Virgin, Orange, T-Mobile and The People's Operator; Band 1 at 1930–1990 MHz uplink and 2110–2180 MHz downlink carries 3G UMTS data and voice for EE, O2, Vodafone and Three and their hosted MVNOs. The chassis tunes both blocks together through the included Yagi donor aerial and up to four indoor whips across a 1000 m² premises for one hundred simultaneous users.
Why does the 1800 MHz block keep EE-business calls and 4G browsing alive through a large office, shop and hotel where staff phones alone drop behind masonry?
EE allocates the 1800 MHz spectrum across both circuit voice and 4G packet data, so one handset keeps a normal call and a 4G session on the same band stages the DW1000 amplifies. The ≥75 dB downlink gain recovers the faint block behind brick, double glazing and concrete slabs, and the interior whips re-radiate it through the reception, meeting rooms, upper office, retail bay and bar area; no separate voice band is required for these EE-family brands.
When an O2, Vodafone or Three guest SIM loses its stronger 4G session inside an office floor, hotel corridor or warehouse aisle, what role does the 2100 MHz 3G stage still play for calls and low-bandwidth sessions?
A non-EE guest or staff SIM whose stronger 4G session fails behind a partition can still place a call, send a message, share a location fix or hold a low-bandwidth hotspot over the amplified 2100 MHz UMTS block, because 3G carries both circuit voice and packet data. This common cross-network reserve keeps mixed-carrier guests in a hotel corridor, booking devices in a clinic and staff laptops tethered on Three moving between zones; a single-band Band 3 repeater could not hold that O2, Vodafone or Three session at all.
How do the 70/75 dB commercial gain figures compare with the 500m² DW500 tier, and why does that extra headroom reach four antennas and a hundred users?
The DW1000 keeps the same ≥20 dBm output as the DW500 but raises the gain by ten dB: ≥70 dB uplink and ≥75 dB downlink against the DW500's ≥60/65 dB. That commercial-stage recovery extends the field from three zones and fifty users to four antennas and one hundred handsets across a 1000 m² footprint; the ≤5 dB noise figure keeps the field clear of hiss, the included Yagi supplies a stronger distant donor bearing, and the 4-way splitter distributes the recovered block over separate rooms, floors and warehouse bays.
List the business MVNO brands by their leased host on this repeater, and identify which SIMs receive no EE 1800 call circuit indoors.
EE, BT Mobile, ASDA Mobile, Virgin Mobile, Orange, T-Mobile and The People's Operator ride the EE host and receive the Band 3 voice and 4G layer; giffgaff, Tesco Mobile, Sky Mobile, Lycamobile and Plusnet ride O2; Smarty and iD Mobile ride Three; Lebara and Talkmobile ride Vodafone; FreedomPop and TalkTalk lease a fallback host per plan. Only the EE-hosted brands receive the Band 3 call circuit; every other host relies on Band 1 3G indoors through this chassis.
If the building lies beyond a 3G cell boundary, which leased-EE handsets continue to place normal calls on the tuned 1800 MHz circuit, and which guest or staff SIM loses its redundant circuit channel on this chassis?
EE, BT, ASDA and Virgin handsets keep the ordinary circuit voice call on the tuned 1800 MHz block even where the surrounding district has no 3G cell, because that circuit voice rides the same Band 3 layer the chassis amplifies. A guest or staff member on O2, Vodafone or Three loses its redundant circuit channel through this model, since Band 1 is the only voice block those hosts receive here; the handset then depends on the host's own fallback, which the repeater cannot supply.
A business phone has 4G Calling turned off in its connection menu; on which tuned circuit block does the EE-brand call then travel between the whip and the donor mast, and does the same block serve an O2 or Three SIM?
With 4G Calling off, the EE-brand call drops onto the Band 3 circuit voice channel on the same 1800 MHz block the chassis carries beside the 4G data layer; it follows the main whip and any branch whips like a normal Band 3 session. An O2, Vodafone or Three SIM does not receive that Band 3 circuit channel on this model, so the fallback applies only to EE-hosted handsets.
What three airwaves does this radio chassis skip entirely — the rural 800 MHz data layer, the 900 MHz legacy call layer and the new 5G standard — and which neighbouring Boost4U band combination covers each gap?
This radio chassis skips the Band 20 800 MHz rural data layer, the Band 8 900 MHz legacy call layer and every 5G NR standard; a donor reading that lives only on 800 MHz needs the CD1000, CG1000 or CW1000 combos, a handset on a 2G circuit call needs the Band 8 model represented by the CG range, and no current indoor repeater in this family supports 5G. The chassis also cannot assist where the outside phone reads zero bars on the tuned bands.
How faint can the outside mast reading be before this commercial chassis stops helping, and which enclosed building sections should be treated as separate donor sites rather than covered from the main whips?
The donor aerial needs at least one to two bars outside the premises on the target Band 3 or Band 1; the chassis enlarges an existing faint block and cannot conjure a signal the mast is not sending. A cellar beneath the donor floor, a steel warehouse bay or insulated metal workshop, a concrete strongroom and a separate outbuilding behind a thick party wall should be planned as their own donor sites with a separate repeater, rather than being covered by pushing one more whip from the main chassis.
Under which Ofcom licence class and conformity marks does this commercial indoor repeater operate, and what spacing prevents it radiating back onto the macro network?
The DW1000 sits in the Ofcom licence-exempt mobile repeater class for indoor use, aligned with the Ofcom Technical Standard for Mobile Repeaters, and carries UKCA, CE and RoHS conformity marks. Feedback onto the macro masts is prevented by the 10 m vertical separation between the Yagi donor and the indoor whips, correct BS and MS port connection, separate indoor and outdoor lead routing, and automatic gain control that balances the field as handsets move between zones; an over-close whip or reversed port can latch oscillation that these spacing rules are designed to stop.
